In recent years, drug-coated balloons(DCBs) have become a new treatment strategy for coronary artery disease, and the drugs used in the coating and the coating technology have progressed in the past years. Without permanent implant, a DCB delivers antiproliferative drugs rapidly and uniformly into the vessel wall via the excipient during a single balloon dilation. Many evidence suggests that DCB angioplasty is an effective measure for dealing with in-stent restenosis and de novo lesions in small coronary vessels.As more clinical studies are published, new evidence is emerging for the use of DCB angioplasty in a wide range of coronary diseases, and the indications are expanding internationally. Based on the latest research from China and elsewhere, the Expert Writing Committee of the Chinese Expert Consensus on Clinical Applications of Drug-Coated Balloon has updated the previous DCB consensus after evidence-based discussions and meetings in terms of adequate preparation of in-stent restenosis lesions, expansion of the indications for coronary de novo lesions, and precise guidance of DCB treatment by intravascular imaging and functional evaluation.展开更多

The preferred treatment strategy for AMI patients is the use of drug-eluting stents (DES), as there is ample evidence to suggest that stent implantation can reduce major adverse cardiovascular events (MACEs). With the application of drug-coated balloons (DCBs) and the enhancement of the concept of interventional without implantation, the question is whether DCBs can be safely and effectively used in patients with AMI? The purpose of this study was to investigate the safety and effectiveness of DCBs in the treatment of AMI. A retrospective review of clinical data was conducted on 55 AMI patients who underwent primary percutaneous coronary intervention (PCI) from January 2020 to December 2021. Of these patients, 25 were treated with DCBs and 30 were treated with DESs. Optical coherence tomography (OCT) was used to measure the minimum lumen diameter, lumen stenosis, and coronary artery dissection before and after surgery, and angina pectoris attacks and various MACEs were recorded at 1, 6, and 12 months after surgery. The results showed that there were no significant differences in clinical baseline data between the two groups. However, the minimum lumen diameter of the DCB group immediately after the operation was smaller than that of the DES group, and the stenosis degree of the lumen in the DCB group was higher than that in the DES group. The incidence of coronary artery dissection in the DCB group was significantly higher than that in the DES group, but the majority of them were type B. At 1, 6, and 12 months after treatment, there was no significant difference in the occurrence of MACEs between the two groups. In conclusion, DCBs is a safe and effective treatment for AMI. However, the incidence of coronary artery dissection in DCB patients is higher than that in DES patients, but the majority of them are type B. .展开更多

[Method] 202 patients undergoing autologous arteriovenous fistula from July 2021 to June 2022 were randomly divided into a control group (101 cases) and an observation group (101 cases) to compare the incidence rates of postoperative complications, hospitalization days, hospitalization expenses, knowledge of self-management of arteriovenous fistula and nursing satisfaction. [Results] In the observation group, the incidence of arteriovenous fistula was higher than that of the control group, and the hospitalization days and hospitalization costs were lower than that of the control group. The difference between the two groups was statistically significant (P < 0.05). [Conclusion] The application of the clinical nursing path to intervene in patients with autologous arteriovenous fistula balloon dilation can reduce the incidence of postoperative complications, shorten the hospital length of time, reduce hospitalization costs and improve patient satisfaction, which is clinical promotion significance.展开更多

文摘Percutaneous coronary interventions have progressed through the era of plain balloon dilation, bare-metal stent insertion to drug-eluting stent treatment, which has significantly reduced the acute occlusion and restenosis rates of target vessels and improved patient prognosis, making drug-eluting stents the mainstream interventional treatment for coronary artery disease. In recent years, drug-coated balloons(DCBs) have become a new treatment strategy for coronary artery disease, and the drugs used in the coating and the coating technology have progressed in the past years. Without permanent implant, a DCB delivers antiproliferative drugs rapidly and uniformly into the vessel wall via the excipient during a single balloon dilation. Many evidence suggests that DCB angioplasty is an effective measure for dealing with in-stent restenosis and de novo lesions in small coronary vessels.As more clinical studies are published, new evidence is emerging for the use of DCB angioplasty in a wide range of coronary diseases, and the indications are expanding internationally. Based on the latest research from China and elsewhere, the Expert Writing Committee of the Chinese Expert Consensus on Clinical Applications of Drug-Coated Balloon has updated the previous DCB consensus after evidence-based discussions and meetings in terms of adequate preparation of in-stent restenosis lesions, expansion of the indications for coronary de novo lesions, and precise guidance of DCB treatment by intravascular imaging and functional evaluation.
文摘Objective:To prospectively follow up a cohort of anterior urethral stricture disease patients managed with balloon dilation(BD)for 3 years to evaluate the long-term outcomes and to study factors that contribute to recurrence.Methods:This study included men who had urethral BD for significant anterior urethral stricture disease between January 2017 and March 2019.Data about the patient age,stricture characteristics,and recurrence date were recorded,along with information on postoperative indwelling catheter use and operative complications.Furthermore,information about the self-calibration procedure was collected and where available,free flow(FF)measurements during the follow-up period were recorded and analyzed.Success was defined as a lack of symptoms and acceptable FF rates(maximum flow rate>12 mL/s).Results:The final analysis was conducted on 187 patients.The mean follow-up period was 37 months.The long-term overall success rate at the end of our study was 66.8%.Our recurrence rate was 7.4%at 12 months,24.7%at 24 months,and reached 33.2%at the end of our study.The time to recurrence ranged from 91 days to 1635 days,with a mean of 670 days.The stricture-free survival was significantly shorter with lengthy peno-bulbar(p=0.031)and multiple strictures(p=0.015),and in the group of patients who were not committed to self-calibration protocol(p<0.011).However,post-procedural self-calibration was the most important factor that may have decreased the incidence of recurrence(odds ratioZ5.85).Adjuvant self-calibration after BD not only reduced the recurrence rate from 85.4%in the non-self-calibration group to 15.1%in the self-calibration one(p<0.001),but also improved the overall stricture-free survival and FF parameters.
文摘Aortic stenosis(AS)stands out as the most prevalent individual valvular defect globally.The onset and progression of AS mirror an active process akin to atherosclerosis,and the traditional triad of symptoms includes chest pain,breathlessness,and loss of consciousness.Prognosis takes a significant downturn when symptoms manifest,with mortality reaching approximately 50%-85% within the subsequent 5 years after symptom onset.
文摘The X-ray sources of the universe are extraterrestrial in nature which emit X-ray photons.The closest strong X-ray source is the Sun,which is followed by various compact sources such as neutron stars,black holes,the Crab pulsar,etc.In this paper,we analyze the data received from several low-cost lightweight meteorological balloon-borne missions launched by the Indian Centre for Space Physics.Our main interest is to study the variation of the vertical intensity of secondary cosmic rays,the detection of strong X-ray sources,and their spectra in the energy band of^(1)0–80 keV during the complete flights.Due to the lack of an onboard pointing system,low exposure time,achieving a maximum altitude of only~42 km,and freely rotating the payload about its axis,we modeled the background radiation flux for the X-ray detector using physical assumptions.We also present the source detection method,observation of the pulsation of the Crab(^(3)3 Hz),and spectra of some sources such as the quiet Sun and the Crab pulsar.

文摘BACKGROUND:Resuscitative endovascular balloon occlusion of the aorta(REBOA)can temporarily control traumatic bleeding.However,its prolonged use potentially leads to ischemia-reperfusion injury(IRI).Partial REBOA(pREBOA)can alleviate ischemic burden;however,its security and eff ectiveness prior to operative hemorrhage control remains unknown.Hence,we aimed to estimate the effi cacy of pREBOA in a swine model of liver injury using an experimental sliding-chamber ballistic gun.METHODS:Twenty Landrace pigs were randomized into control(no aortic occlusion)(n=5),intervention with complete REBOA(cREBOA)(n=5),continuous pREBOA(C-pREBOA)(n=5),and sequential pREBOA(S-pREBOA)(n=5)groups.In the cREBOA and C-pREBOA groups,the balloon was inflated for 60 min.The hemodynamic and laboratory values were compared at various observation time points.Tissue samples immediately after animal euthanasia from the myocardium,liver,kidneys,and duodenum were collected for histological assessment using hematoxylin and eosin staining.RESULTS:Compared with the control group,the survival rate of the REBOA groups was prominently improved(all P<0.05).The total volume of blood loss was markedly lower in the cREBOA group(493.14±127.31 mL)compared with other groups(P<0.01).The pH was significantly lower at 180 min in the cREBOA and S-pREBOA groups(P<0.05).At 120 min,the S-pREBOA group showed higher alanine aminotransferase(P<0.05)but lower blood urea nitrogen compared with the cREBOA group(P<0.05).CONCLUSION:In this trauma model with liver injury,a 60-minute pREBOA resulted in improved survival rate and was effective in maintaining reliable aortic pressure,despite persistent hemorrhage.Extended tolerance time for aortic occlusion in Zone I for non-compressible torso hemorrhage was feasible with both continuous partial and sequential partial measures,and the significant improvement in the severity of acidosis and distal organ injury was observed in the sequential pREBOA.
文摘BACKGROUND Intracranial arterial narrowing is a significant factor leading to brief episodes of reduced blood flow to the brain,known as transient ischemic attacks,or fullblown strokes.While atherosclerosis is commonly associated with intracranial arterial narrowing,it is frequently of a non-atherosclerotic nature in younger patients.CASE SUMMARY Here,we present the case of a young stroke patient with narrowing of the middle cerebral artery(MCA),characterized as non-atherosclerotic lesions,who experienced an ischemic stroke despite receiving standard drug therapy.The patient underwent digital subtraction angiography(DSA)to assess the entire network of blood vessels in the brain,revealing significant narrowing(approximately 80%)in the M1 segment of the right MCA.Subsequently,the patient underwent Drug-Coated Balloon Angioplasty to treat the stenosis in the right MCA's M1 segment.Follow-up DSA confirmed the resolution of stenosis in this segment.Although the remaining branches showed satisfactory blood flow,the vessel wall exhibited irregularities.A review of DSA conducted six months later showed no evident stenosis in the right MCA,with a smooth vessel wall.CONCLUSION The use of drug-coated balloon angioplasty demonstrated favorable outcomes in repairing and reshaping the blood vessel wall in young patients.Therefore,it may be considered a promising treatment option for similar cases.
文摘BACKGROUND Over one-third of Americans carry the diagnosis of obesity,many also with obesity-related comorbidities.This can place patients at increased risk of operative and postoperative complications.The intragastric balloon has been shown to aid in minor weight loss,however its weight recidivism in patients requiring short interval weight loss has not been well studied.AIM To evaluate weight loss,ability to undergo successful elective surgery after intragastric balloon placement,and weight management after balloon removal.METHODS This study is a retrospective review of patients in a single academic institution undergoing intragastric balloon placement from 2019-2023 to aid in weight loss prior to undergoing elective surgery.Clinical outcomes including weight loss,duration of balloon placement,successful elective surgery,weight regain postballoon and post-procedure complications were assessed.Exclusion criteria included those with balloon in place at time of study.RESULTS Thirty-three patients completed intragastric balloon therapy from 2019-2023 as a bridge to elective surgery.All patients were required to participate in a 12-month weight management program to be eligible for balloon therapy.Elective surgeries included incisional hernia repair,umbilical hernia repair,inguinal hernia repair,and knee and hip replacements.The average age at placement was 53 years±11 years,majority(91%)were male.The average duration of intragastric balloon therapy was 186 days±41 days.The average weight loss was 14.0 kg±7.4 kg and with an average percent excess body weight loss of 30.0%(7.9%-73.6%).Over half of the patients(52.0%)achieved the goal of 30-50 lbs(14-22 kg)weight loss.Twenty-one patients(64%)underwent their intended elective surgery,2 patients(6%)deferred surgery due to symptom relief with weight loss alone.Twenty-one of the patients(64%)have documented weights in 3 months after balloon removal,in these patients the majority(76%)gained weight after balloon removed.In patients with weight regain at 3 months,they averaged 5.8 kg after balloon removal in the first 3 months,this averaged 58.4%weight regain of the initial weight lost.CONCLUSION Intragastric balloon placement is an option for short-term weight management,as a bridge to elective surgery in patients with body mass index(BMI)>35.Patients lost an average of 14 kg with the balloon,allowing two-thirds of patients to undergo elective surgery at a healthy BMI.However,most patients regained an average of 58%of the original weight lost after balloon removal.The intragastric balloon successfully serves as a tool for rapid weight loss,though patients must be educated on the risks including weight regain.
文摘BACKGROUND Endoscopic retrograde cholangiopancreatography(ERCP),with its clinical ad-vantages of less trauma and faster recovery,has become the primary treatment for choledocholithiasis.AIM To investigate the effects of different ERCP procedures on the sphincter of Oddi.METHODS The clinical data of 91 patients who underwent ERCP at Yixing Hospital of Traditional Chinese Medicine between February 2018 and February 2021 were analyzed retrospectively.The patients were divided into endoscopic sphinc-terotomy(EST,n=24)and endoscopic papillary balloon dilation(EPBD,n=67)groups.The duration of operation,pancreatic development,pancreatic sphinc-terotomy,intubation difficulties,stone recurrence,and incidence of reflux cho-langitis and cholecystitis were statistically analyzed in patients with a history of choledocholithiasis,pancreatitis,and Oddi sphincter dysfunction in the EST and EPBD groups.RESULTS Differences in hypertension,diabetes,increased bilirubin,small diameter of the common bile duct,or ampullary diverticulum between the two groups were not significant.Statistically significant differences were observed between the two groups concerning sex and age(<60 years).Patients with a history of choledocholithiasis,pancreatitis,and Oddi sphincter dysfunction were higher in the EST group than in the EPBD group.The number of cases of pancreatic development,pancreatic duct sphincterotomy,and difficult intubation were higher in the EST group than in the EPBD group.The number of Oddi’s sphincter manometries,ERCP surgical outcomes,and guidewires entering the pancreatic duct several times in EST group were lower than those in the EPBD group.The numbers of stone recurrences,reflux cholangitis,and cholecystitis were higher in the EST group than in the EPBD group.CONCLUSION In summary,common bile duct stones,pancreatitis history,and multiple guided wire introductions into the pancreatic duct are independent risk factors for EST and EPBD.Based on this evidence,this study can provide actionable insights for clinicians and researchers.
文摘The incidence of acute myocardial infarction (AMI) is increasing year by year, which seriously endangers human health around the world. The preferred treatment strategy for AMI patients is the use of drug-eluting stents (DES), as there is ample evidence to suggest that stent implantation can reduce major adverse cardiovascular events (MACEs). With the application of drug-coated balloons (DCBs) and the enhancement of the concept of interventional without implantation, the question is whether DCBs can be safely and effectively used in patients with AMI? The purpose of this study was to investigate the safety and effectiveness of DCBs in the treatment of AMI. A retrospective review of clinical data was conducted on 55 AMI patients who underwent primary percutaneous coronary intervention (PCI) from January 2020 to December 2021. Of these patients, 25 were treated with DCBs and 30 were treated with DESs. Optical coherence tomography (OCT) was used to measure the minimum lumen diameter, lumen stenosis, and coronary artery dissection before and after surgery, and angina pectoris attacks and various MACEs were recorded at 1, 6, and 12 months after surgery. The results showed that there were no significant differences in clinical baseline data between the two groups. However, the minimum lumen diameter of the DCB group immediately after the operation was smaller than that of the DES group, and the stenosis degree of the lumen in the DCB group was higher than that in the DES group. The incidence of coronary artery dissection in the DCB group was significantly higher than that in the DES group, but the majority of them were type B. At 1, 6, and 12 months after treatment, there was no significant difference in the occurrence of MACEs between the two groups. In conclusion, DCBs is a safe and effective treatment for AMI. However, the incidence of coronary artery dissection in DCB patients is higher than that in DES patients, but the majority of them are type B. .

文摘BACKGROUND Incomplete congenital duodenal obstruction(ICDO)is caused by a congenitally perforated duodenal web(CPDW).Currently,only six cases of balloon dilatation of the PDW in newborns have been described.AIM To present our experience of balloon dilatation of a perforated duodenal memb-rane in newborns with ICDO.METHODS Five newborns who underwent balloon dilatation of the CPDW along a prein-stalled guidewire between 2021 and 2023 were included.Nineteen newborns diagnosed with ICDO who underwent laparotomy were included in the control group.RESULTS In all cases,good anatomical and clinical results were obtained.In three cases,a follow-up study was conducted after 1 year.The average time to start enteral feeding per os was significantly earlier in the study group(4.4 d)than in the laparotomic group(21.2 days;P<0.0001).The time spent by patients in the intensive care unit and hospital after balloon dilatation was also significantly shorter.We determined the selection criteria for possible and effective CPDW balloon dilatation in newborns as follows:(1)Presence of dynamic radiographic signs of the passage of a radiopaque substance beyond the zone of narrowing or radiographic signs of pneumatisation of the duodenum and small bowel distal to the web;(2)presence of endoscopic signs of CPDW;(3)successful cannulation with a guidewire performed parallel to the endoscope,with holes in the congenital duodenal web;and(4)successful positioning of the balloon performed along a freestanding guidewire on the web.CONCLUSION Strictly following selection criteria for newborns with ICDO caused by CPDW ensures that endoscopic balloon dilatation using a pre-installed guidewire is safe and effective and shows good 1-year follow-up results.
文摘BACKGROUND The goal of therapy for traumatic carotid-cavernous fistula(TCCF)is the elimination of fistula while maintaining patency of the parent artery.The treatment for TCCF has evolved from surgery to endovascular management using detachable balloons,coils,liquid embolic agents,covered stents,or flow-diverter stent through arterial or venous approaches.Despite the withdrawal of detachable balloons from the market in the United States since 2004,transarterial embolization with detachable balloons has currently remained the best initial treatment for TCCF in several countries.However,the pseudoaneurysm formation following transarterial detachable balloon embolization has rarely been observed in long-term follow-up.AIM To determine the occurrence and long-term follow-up of pseudoaneurysm after transarterial detachable balloon for TCCF.METHODS Between January 2009 and December 2019,79 patients diagnosed with TCCF were treated using detachable latex balloons(GOLDBAL)of four sizes.Pseudoaneurysm sizes were stratified into five grades for analysis.Initial and follow-up assessments involved computed tomography angiography at 1 month,6 month,1 year,and longer intervals for significant cases.Clinical follow-ups occurred semi-annually for 2 years,then annually.Factors analyzed included sex,age,fistula size and location,and balloon size.RESULTS In our cohort of 79 patients treated for TCCF,pseudoaneurysms formed in 67.1%,with classifications ranging from grade 0 to grade 3;no grade 4 or giant pseudoaneurysms were observed.The majority of pseudoaneurysms did not progress in size,and some regressed spontaneously.Calcifications developed in most large pseudoaneurysms over 5-10 years.Parent artery occlusion occurred in 7.6%and recurrent fistulas in 16.5%.The primary risk factors for pseudoaneurysm formation were identified as the use of specific balloon sizes,with balloon SP and No.6 significantly associated with its occurrence(P=0.005 and P=0.002,respectively),whereas sex,age,fistula size,location,and the number of balloons used were not significant predictors.CONCLUSION Pseudoaneurysm formation following detachable balloon embolization for TCCF is common,primarily influenced by the size of the balloon used.Despite this,all patients with pseudoaneurysms remained asymptomatic during long-term follow-up.
文摘[Objective] To explore the effect of clinical care pathways in perioperative patients with autologous arteriovenous fistula balloon expansion. [Method] 202 patients undergoing autologous arteriovenous fistula from July 2021 to June 2022 were randomly divided into a control group (101 cases) and an observation group (101 cases) to compare the incidence rates of postoperative complications, hospitalization days, hospitalization expenses, knowledge of self-management of arteriovenous fistula and nursing satisfaction. [Results] In the observation group, the incidence of arteriovenous fistula was higher than that of the control group, and the hospitalization days and hospitalization costs were lower than that of the control group. The difference between the two groups was statistically significant (P < 0.05). [Conclusion] The application of the clinical nursing path to intervene in patients with autologous arteriovenous fistula balloon dilation can reduce the incidence of postoperative complications, shorten the hospital length of time, reduce hospitalization costs and improve patient satisfaction, which is clinical promotion significance.

文摘OBJECTIVE To access the efficacy and safety of the double-ProGlide technique for the femoral vein access-site closure in cryoballoon ablation with uninterrupted oral anticoagulants(OAC),and its impact on the electrophysiology laboratory time as well as hospital stay after the procedure in this observational study.METHODS Patients with atrial fibrillation undergoing cryoballoon ablation with uninterrupted OAC at Department of Cardiology,Beijing Anzhen Hospital,Capital Medical University,Beijing,China from May 2019 to May 2021 were enrolled in this study.From October 2020,double-ProGlide technique was consistently used for hemostasis(ProGlide group),and before that conventional manual compression was utilized(manual compression group).The occurrence of vascular and groin complications was accessed during the hospital stay and until the three-month follow-up.RESULTS A total of 140 participants(69.30%of male,mean age:59.21±10.29 years)were evaluated,70 participants being in each group.Immediate hemostasis was achieved in all the patients with ProGlide closure.No major vascular complications were found in the ProGlide group while two major vascular complications were occurred in the manual compression group.The incidence of any groin complication was obviously higher in subjects with manual compression than patients with ProGlide devices(15.71%vs.2.86%,P=0.009).In addition,compared with the manual compression group,the ProGlide group was associated with significantly shorter total time in the electrophysiology laboratory[112.0(93.3–128.8)min vs.123.5(107.3–158.3)min,P=0.006],time from sheath removal until venous site hemostasis[3.8(3.4–4.2)min vs.8.0(7.6–8.5)min,P<0.001],bed rest time[8.0(7.6–8.0)h vs.14.1(12.0–17.6)h,P<0.001]and hospital stay after the procedure[13.8(12.5–17.8)h vs.38.0(21.5–41.0)h,P<0.001].CONCLUSIONS Utilization of the double-ProGlide technique for hemostasis after cryoballoon ablation with uninterrupted OAC is feasible and safe,which has the clinical benefit in reducing the total electrophysiology laboratory time and the hospital stay length after the procedure.

文摘Hemorrhagic shock is a life-threatening disease often encountered in emergency departments(EDs).Hemorrhagic shock caused by extensive bleeding from multiple sites is often associated with high mortality and morbidity.In recent years,resuscitative endovascular balloon occlusion of the aorta(REBOA)has been widely used in traumatic hemorrhagic shock and is considered to be an effective resuscitation measure.[1]Some studies reported that REBOA was also effective for non-traumatic hemorrhage.[2,3]In this study,we report a case of hemorrhagic shock caused by acute upper gastrointestinal bleeding that was successfully treated and received REBOA to obtain a transition time.This report may provide feasible options for emergency physicians,gastroenterologists,or surgeons to more actively treat refractory gastrointestinal bleeding.

文摘BACKGROUND For the past few years,preventive interventional therapy has been widely used domestically and overseas,bringing great benefits to pregnant women at high-risk for complications,such as pernicious placenta previa(PPP)and placenta accreta.Nevertheless,there are still few reports on surgical complications related to interventional therapy,and its safety should be a concern.CASE SUMMARY We report a 36-year-old pregnant woman with PPP who underwent balloon implantation in the lower segment of the abdominal aorta before caesarean section.However,the balloon shifted during the operation,which damaged the arterial vessels after filling,resulting in severe postpartum haemorrhage in the patient.Fortunately,after emergency interventional stent implantation,the pa-tient was successfully relieved of the massive haemorrhage crisis.CONCLUSION It seems that massive postoperative bleeding has been largely avoided in preventive interventional therapy in high-risk pregnant women with placenta-related diseases,but surgical complications related to intervention therapy can also cause adverse consequences.It is equally important for clinical doctors to learn how to promptly identify and effectively treat these rare complications.
文摘Endoscopically placed intragastric balloons(IGBs)have played a significant role in obesity treatment over the last 30 years,successfully bridging the gap between lifestyle modification/pharmacotherapy and bariatric surgery.Since they provide a continuous sensation of satiety that helps the ingestion of smaller portions of food,facilitating maintenance of a low-calorie diet,they have generally been considered an effective and reversible,less invasive,non-surgical procedure for weight loss.However,some studies indicate that balloons have limited sustainable effectiveness for the vast majority attempting such therapy,resulting in a return to the previous weight after balloon removal.In this review we try to summarize the pros and cons of various balloon types,to guide decision making for both the physician and the obese individual looking for effective treatment.We analyzed the six most commonly used IGBs,namely the liquid-filled balloons Orbera,Spatz3,ReShape Duo and Elipse,and the gas-filled Heliosphere and Obalon-also including comments on the adjustable Spatz3,and the swallowable Obalon and Elipse-to optimize the choice for maximum efficacy and safety.

文摘BACKGROUND Controversy exists as to the optimal treatment approach for ostial left anterior descending(LAD)or ostial left circumflex artery(LCx)lesions.Drug-coated balloons(DCB)may overcome some of the limitations of drug-eluting stents(DES).Therefore,we investigated the security and feasibility of the DCB policy in patients with ostial LAD or ostial LCx lesions,and compared it with the conventional DES-only strategy.METHODS We retrospectively enrolled patients with de novo ostial lesions in the LAD or LCx who underwent interventional treatment.They were categorized into two groups based on their treatment approach:the DCB group and the DES group.The treatment strategies in the DCB group involved the use of either DCB-only or hybrid strategies,whereas the DES group utilized crossover or precise stenting techniques.Two-year target lesion revascularization was the primary endpoint,while the rates of major adverse cardiovascular events,cardiac death,target vessel myocardial infarction,and vessel thrombosis were the secondary endpoints.Using propensity score matching,we assembled a cohort with comparable baseline characteristics.To ensure result analysis reliability,we conducted sensitivity analyses,including interaction,and stratified analyses.RESULTS Among the 397 eligible patients,6.25%of patients who were planned to undergo DCB underwent DES.A total of 108 patients in each group had comparable propensity scores and were included in the analysis.Two-year target lesion revascularization occurred in 5 patients(4.90%)and 16 patients(16.33%)in the DCB group and the DES group,respectively(odds ratio=0.264,95%CI:0.093–0.752,P=0.008).Compared with the DES group,the DCB group demonstrated a lower major adverse cardiovascular events rate(7.84%vs.19.39%,P=0.017).However,differences with regard to cardiac death,non-periprocedural target vessel myocardial infarction,and definite or probable vessel thrombosis between the groups were non-significant.CONCLUSIONS The utilization of the DCB approach signifies an innovative and discretionary strategy for managing isolated ostial lesions in the LAD or LCx.Nevertheless,a future randomized trial investigating the feasibility and safety of DCB compared to the DES-only strategy specifically for de novo ostial lesions in the LAD or LCx is highly warranted.
文摘BACKGROUND Pulmonary vein stenosis(PVS)is an uncommon but known cause of morbidity and mortality in adults and children and can be managed with percutaneous revascularization strategies of pulmonary vein balloon angioplasty(PBA)or pulmonary vein stent implantation(PSI).AIM To study the safety and efficacy outcomes of PBA vs PSI in all patient categories with PVS.METHODS We performed a literature search of all studies comparing outcomes of patients evaluated by PBA vs PSI for PVS.We selected all published studies comparing PBA vs PSI for PVS with reported outcomes of restenosis and procedure-related complications in all patient categories.In adults,PVS following atrial fibrillation ablation and in children PVS related to congenital etiology or post-procedural PVS following total or partial anomalous pulmonary venous return repair were included.The patient-centered outcomes were risk of restenosis requiring re-intervention and procedural-related complications.The metaanalysis was performed by computing odds ratios(ORs)using the random effects model based on underlying statistical heterogeneity.RESULTS Eight observational studies treating 768 severe PVS in 487 patients met our inclusion criteria.The age range of patients was 6 months to 70 years and 67%were males.The primary outcome of the re-stenosis requiring re-intervention occurred in 196 of 325 veins in the PBA group and 111 of 443 veins in the PSI group.Compared to PSI,PBA was associated with a significantly increased risk of re-stenosis(OR 2.91,95%CI:1.15-7.37,P=0.025,I2=79.2%).Secondary outcomes of the procedurerelated complications occurred in 7 of 122 patients in the PBA group and 6 of 69 in the PSI group.There were no statistically significant differences in the safety outcomes between the two groups(OR:0.94,95%CI:0.23-3.76,P=0.929,I^(2)=0.0%).CONCLUSION Across all patient categories with PVS,PSI is associated with reduced risk of re-intervention and is as safe as PBA and should be considered first-line therapy for PVS.
