Descriptive and analytical methods of epidemiologywere applied. The universally acknowledged methodology used in sanitary statistics is used to calculatethe extensive, crude, and age-specific mortality rates. Results: Kazakhstan is thought to be seeing an increase inmortality from VSDs in children. As a result, this study for the years 2011 to 2020 was conducted to retrospectivelyassess data from the central registration of the Bureau of National Statistics that was available throughoutthe nation. Age-standardized mortality data were obtained and compared between age categories. It was shownthat 507 children died from this condition throughout the time period under study. The average annual standardizedmortality rate was 1.88 per 100,000 population and tended to decrease over time. The peak of mortality wasnoted at the age of up to 1 year, namely the neonatal period. Cartogram mortality rates were calculated usingstandardized indicators. Additionally, age-sex variations were taken into account when performing all calculations.Conclusion: In recent years, the death rate from VSD has declined from 1.5 to 0.6 per 100,000 people, withthe trend remaining constant (T = 1.4%, R^(2) = 0.5825). The analysis of mortality trends related to VSD is crucial inboth theoretical and practical aspects, as it enables early detection and treatment of VSDs. The findings of thisstudy will be valuable to public health authorities in developing a strategy to treat VSDs effectively.展开更多

This study aims to useRT-3DE to evaluate the changes in biventricular volume and systolic function in children with ventricular septaldefect (VSD) and moderate to severe pulmonary hypertension (PH) before surgery. Methods: In this study18 children with VSD and moderate to severe PH (VSD + PH Group) and 18 healthy children of the sameage (Control Group) were recruited. Biventricular volume and systolic function were evaluated by RT-3DE.The measurements included: left and right ventricular volume indexed to body surface area (BSA), stroke volume(SV) indexed to BSA, and ejection fraction (EF). Results: The results showed left and right ventricular volumeindexed to BSA and SV indexed to BSA were significantly increased in VSD + PH Group (VSD + PH Groupvs. Control Group), LVEDV/BSA (ml/m2): 48.67 ± 21.46 vs. 25.59 ± 6.96, RVEDV/BSA (ml/m2): 55.98 ±15.35 vs. 27.69 ± 4.37, LVSV/BSA (ml/m2): 24.08 ± 9.30 vs. 15.14 ± 4.29, RVSV/BSA (ml/m2): 26.02 ± 8.87 vs.14.11 ± 2.89, (P < 0.05). While for EF in VSD + PH Group decreased (VSD + PH Group vs. Control Group),LVEF: 50.93 ± 7.50% vs. 59.38 ± 7.24%, RVEF: 45.84 ± 7.71% vs. 51.05 ± 6.90% (P < 0.05). Conclusion: Inchildren with VSD and moderate to severe PH, increased biventricular volume and decreased systolic functionwere observed with RT-3DE, but biventricular systolic function remained within acceptable limits. The childrenin this study recovered well after surgery without serious perioperative complications, suggesting that biventricularsystolic function may help facilitate the surgical decision-making process in children with VSD and moderate-toseverePH.展开更多

Methods Between September 2011 and February 2013, we collected 40 patients who underwent perventricular closure via a small lower sternal incision(minimally invasive group), aged 15.5±3.5 years(12 months to 32 years) with a body weight of 24.2±7.5 kg(10.8-58.0 kg). The mean size of VSD was 5.6±0.5 mm(2-14 mm). Another 40 patients were included as the surgical group, receiving the conventional surgical repair of VSD. The device of the minimally invasive group was released under the guidance of transesophageal echocardiography. Success rate, cardiac indicators, and clinical outcomes of the 2 groups were compared. Results The patients in the surgical group and those in the minimally invasive group showed similar results in success rate(both 97.5%). The procedure time, intensive care unit stay, hospital stay, and postoperative recovery time in the minimally invasive group were significantly shorter than those in the surgical group(58±21 minutes versus 145±26 minutes, 2±1 days versus 8±3 days, 5±1 days versus 16±6 days, 3±1 days versus 90±20 days, all P<0.05). The minimally invasive group had a higher incidence of conduction anomalies(17.5% versus 2.5%, P<0.05). In the follow-up period of 3-12 months, there was no new residual shunt, noticeable aortic regurgitation, significant arrhythmias, or device failure except for new complications in the surgical group. Conclusions The success rate of minimally invasive perventricular device closure of VSD under transesophageal echocardiography guidance is similar to that of conventional surgical repair, but the short-term outcomes of the minimally invasive approach is much better. Long-term follow-up is necessary to confirm the effectiveness of this technique.展开更多

However, the minimally invasive method of transcatheter closure has always attracted the attention of cardiologists and patients. The present study aimed to apply transcatheter occlusion in treating ventricular septal defect with right coronary cusp bulge and further evaluate the clinical effect through follow-up. Materials and methods: A total of 40 children diagnosed as having a ventricular septal defect with right coronary cusp bulge, examined using transthoracic echocardiography and cardiovascular angiography, were enrolled in this study. The ventricular septal defects were closed by placing occluders through transcatheter occlusion treatment. During the operation process, the children underwent angiography and transthoracic echocardiography examinations to check the position of the occlude and the extent of aortic regurgitation. The influence of occlusion on the conduction system was evaluated using a surface electrocardiogram. The children were followed up after their procedures. Results: All 40 patients were immediately and successfully occluded. Three patients with filament residual shunts were observed during the operations. No major surgical complications occurred during the perioperative period. During the follow-up period, the positions of all the occluders were good, the residual shunts in the three patients disappeared, and no new or aggravated aortic regurgitation occurred. Electrocardiogram did not reveal any atrioventricular blocks. Only one patient suffered from an incomplete right bundle branch block. Conclusions: Children diagnosed with ventricular septal defect combined with right coronary cusp bulge could be considered for transcatheter occlusion. With appropriate indications and methods, the effect may be favorable.展开更多

However, whether certain defects such as PmVSD with abnormally attached tricuspid are fit for interventional treatment is still disputable.AIM To explore the feasibility and safety of transcatheter closure of PmVSD with abnormally attached tricuspid chordae tendineae using an improved patent ductus arteriosus(PDA) occluder.METHODS We retrospectively analyzed 20 patients diagnosed with PmVSD with abnormally attached tricuspid chordae tendineae who underwent interventional treatment using an improved PDA occluder at our center from January 2012 to January 2016. Baseline characteristics and procedural and follow-up data were analyzed.RESULTS All 20 patients achieved procedure success. No heart block occurred during the operation. One patient had a transient complete right bundle branch block within48 h post-procedure and reverted to normal rhythm after intravenous injections of dexamethasone for 3 d. For all 20 patients, no residual shunt was observed by transthoracic echocardiography post-procedure. During the average follow-up period of 2.4 years, no severe TR was observed.CONCLUSION Using of the improved PDA occluder for the transcatheter closure of PmVSD with abnormally attached tricuspid chordae tendineae is a safe and promising treatment option. However, long-term follow-up in a large group of patients is still warranted.展开更多

Information was collected on collateral origin, arch sidedness, presence of central pulmonary arteries, and presence of an aberrant subclavian vessel. While patients with 22q11 deletion were more likely to have collateral origin from brachiocephalic vessels, patients without 22q11 deletion were more likely to have collateral origin from the descending aorta. There was no significant difference in arch sidedness or the presence of central pulmonary arteries. Patients with 22q11 deletion were more likely to have an aberrant subclavian artery (15/46 vs 5/54, p < 0.05), whether a left or right arch was present. Nine of the fifteen 22q11 deletion patients had a collateral originating from an aberrant subclavian artery.

文摘Background:The optimal surgical timing and clinical outcomes of ventricular septal defect(VSD)closure in neo-nates remain unclear.We aimed to evaluate the clinical outcomes of VSD closure in neonates(age≤30 days).Methods:We retrospectively reviewed 50 consecutive neonates who underwent VSD closure for isolated VSDs between August 2003 and June 2021.Indications for the procedure included congestive heart failure/failure to thrive and pulmonary hypertension.Major adverse events(MAEs)were defined as the composite of all-cause mortality,reoperation,persistent atrioventricular block,and significant(≥grade 2)valvular dysfunction.Results:The median age and body weight at operation were 26.0 days(interquartile range[IQR],18.8–28.3)and 3.7 kg(IQR,3.3–4.2),respectively.The median follow-up duration was 110.4 months(IQR,56.8–165.0).Seven patients required preoperative respiratory support,andfive had significant(≥grade 2)preoperative valvular dysfunction.One early mortality occurred due to irreversible cardiogenic shock;no late mortality was observed.One reopera-tion was due to hemodynamically significant residual VSD at 103.8 months postoperatively.The overall survival,freedom from reoperation,and freedom from MAE at 15-years were 98.0%,96.3%,and 94.4%,respectively.Pre-operative mechanical ventilation was associated with a longer duration of postoperative mechanical ventilation(p<0.001)and a longer length of intensive care unit stay(p<0.001).Conclusions:VSD closure with favorable outcomes without morbidities is feasible even in neonates.However,neonates requiring preoperative respiratory support may require careful postoperative management considering the long-term postoperative risks.Overall,surgical VSD closure might be indicated earlier in neonates with respiratory compromise.
文摘Introduction:Transcatheter closure is an alternative to ventricular septal defect(VSD)occlusion surgery.Nit-Occlud LêVSD coil is a new device yet to be evaluated.The study aimed to evaluate immediate and midterm results after transcatheter closure with the Nit-Occlud LêVSD device.Methods:The retrospective analysis included 30 patients with VSD referred for closure during the period from October 2015 to December 2020.Results:At the time of intervention,the patients’mean age and body weights were 7.5±5.6 years and 29.3±19.1 kg.The majority of the defects had perimembranous location(24/30),four defects had muscular and two outlet subaortic position.The mean effective right-side diameter of the VSDs was 3.6±1.3 mm.Single ventricular fibrillation,device embolization,and hemolysis developed in different patients and were successfully treated.None of the patients had a complete atrioventricular block.The coil was successfully placed in 25/30(83.3%)patients.The majority of the devices were 10 mm×6 mm(11/25)and 12 mm×8 mm(8/25)in size.Two patients required the implantation of a second device.The follow-up period was 2.1±1.4 years.Complete VSD closure was achieved in 48%of cases immediately after the intervention,74%during 2.1±1.6 months after the procedure,and 81%over follow-up.The remaining patients had a trivial residual defect.During the follow-up,approximately one-third of patients developed trivial aortic and mitral valve regurgitation,and half of the patients acquired trace/mild tricuspid regurgitation.Standardized(z-score)left ventricular end-diastolic diameter(0.15±0.37 vs.0.92±0.82,p=0.005)and left atrium dimension(0.47±0.58 vs.1.89±1.11,p=0.005),as well as the left atrium to aortic root ratio(1.2±0.1 vs.1.4±0.2,p=0.005)showed a significant decrease over follow-up related to the period before intervention.Conclusion:Intervention with Nit-OccludLêVSD coil showed appropriate results regarding VSD closure rate,complications,and chamber remodeling.The introduction of this device into clinical practice is a significant step forward in transcatheter perimembranous VSD occlusion.
文摘Objective: The aim is to study the trends in ventricular septal defect (VSD) mortality in children in Kazakhstan.Methods: The retrospective study was done for the period 2011–2020. Descriptive and analytical methods of epidemiologywere applied. The universally acknowledged methodology used in sanitary statistics is used to calculatethe extensive, crude, and age-specific mortality rates. Results: Kazakhstan is thought to be seeing an increase inmortality from VSDs in children. As a result, this study for the years 2011 to 2020 was conducted to retrospectivelyassess data from the central registration of the Bureau of National Statistics that was available throughoutthe nation. Age-standardized mortality data were obtained and compared between age categories. It was shownthat 507 children died from this condition throughout the time period under study. The average annual standardizedmortality rate was 1.88 per 100,000 population and tended to decrease over time. The peak of mortality wasnoted at the age of up to 1 year, namely the neonatal period. Cartogram mortality rates were calculated usingstandardized indicators. Additionally, age-sex variations were taken into account when performing all calculations.Conclusion: In recent years, the death rate from VSD has declined from 1.5 to 0.6 per 100,000 people, withthe trend remaining constant (T = 1.4%, R^(2) = 0.5825). The analysis of mortality trends related to VSD is crucial inboth theoretical and practical aspects, as it enables early detection and treatment of VSDs. The findings of thisstudy will be valuable to public health authorities in developing a strategy to treat VSDs effectively.
文摘Background:Ventricular septal defect(VSD)is the most common congenital heart disease.Transcatheter VSD closure is an effective treatment for patients with muscular and perimembranous VSD.However,there is a limit data for outlet VSD,especially impact to the aortic valve leaflet after transcatheter closure.This study aims to assess the outcomes of transcatheter closure of the outlet-type ventricular septal defect(OVSD)after 1 postoperative year.Methods:A retrospective study was performed including 50 patients who underwent transcatheter(n=25)and surgical(n=25)OVSD closure during the exact time frame at two medical centres.Results:The median age and body weight of patients in the transcatheter group were significantly higher than those of patients in the surgical group(7.0 vs.2.8 years;27.0 vs.11.4 kg;p<0.01).The defect size in the surgical group was significantly larger than that in the transcatheter group(5.0 vs.3.0 mm;p<0.01).All OVSD patients have successful transcatheter closure(100%)as effective as surgical closure.Less than small residual shunt was present 20%and 8%immediately after the procedure in the transcatheter and surgical groups(p=0.50),which decreased to 12%and 4%at the 1-year follow-up(p=0.61),respectively.No incidence of complete atrioventricular block and other complications was observed in both groups,and no significant differences were noted in the new onset or worsening of the aortic regurgitation in both groups(p=1.0).Conclusions:Transcatheter treatment could be effectively and safely achieved for OVSD closure at 1-year follow-up.
文摘Background:There is no gold standard sedation method for pediatric cardiac catheterization.In congenital heart diseases with intracardiac shunts,hemodynamic parameters are prone to change depending on the ventilation conditions and anesthetics,although few studies have examined these effects.The purpose of this study was to investigate the effects of two different sedation methods on the hemodynamic parameters.Methods:This study retrospectively evaluated consecutive patients with ventricular septal defect(VSD)below 1 year of age who underwent cardiac catheterization at Aichi Children’s Health and Medical Center,who were divided into age-and VSD diameter-matched general anesthesia(GA)and monitored anesthesia care(MAC)under the natural airway groups(n=40 each),for comparison of hemodynamic parameters.Results:In the GA group,arterial blood pH and arterial partial pressure of oxygen were significantly higher(p<0.01),whereas arterial partial pressure of carbon dioxide was significantly lower than in the MAC group(p<0.01).Mean pulmonary artery pressure(p<0.05)and systemic blood pressure(p<0.01)were lower in the GA group.Pulmonary vascular resistance index(p<0.01)and systemic vascular resistance index(p<0.01)were also significantly lower in the GA group than the MAC group.There were no significant differences in pulmonary blood flow index,systemic blood flow index,and pulmonary/systemic blood flow ratio between the two groups.Conclusions:Cardiac catheterization under GA in VSD patients results in different hemodynamic parameters compared to that under MAC.In particular,when using pulmonary artery pressure and pulmonary vascular resistance measured under GA for judgment regarding the surgical indications or perioperative management,consideration should be given to the fact that these parameters might be lower compared to those measured under MAC.

文摘Background: Real-time three-dimensional echocardiography (RT-3DE) could obtain ventricular volume andejection fraction rapidly and non-invasively without relying on ventricular morphology. This study aims to useRT-3DE to evaluate the changes in biventricular volume and systolic function in children with ventricular septaldefect (VSD) and moderate to severe pulmonary hypertension (PH) before surgery. Methods: In this study18 children with VSD and moderate to severe PH (VSD + PH Group) and 18 healthy children of the sameage (Control Group) were recruited. Biventricular volume and systolic function were evaluated by RT-3DE.The measurements included: left and right ventricular volume indexed to body surface area (BSA), stroke volume(SV) indexed to BSA, and ejection fraction (EF). Results: The results showed left and right ventricular volumeindexed to BSA and SV indexed to BSA were significantly increased in VSD + PH Group (VSD + PH Groupvs. Control Group), LVEDV/BSA (ml/m2): 48.67 ± 21.46 vs. 25.59 ± 6.96, RVEDV/BSA (ml/m2): 55.98 ±15.35 vs. 27.69 ± 4.37, LVSV/BSA (ml/m2): 24.08 ± 9.30 vs. 15.14 ± 4.29, RVSV/BSA (ml/m2): 26.02 ± 8.87 vs.14.11 ± 2.89, (P < 0.05). While for EF in VSD + PH Group decreased (VSD + PH Group vs. Control Group),LVEF: 50.93 ± 7.50% vs. 59.38 ± 7.24%, RVEF: 45.84 ± 7.71% vs. 51.05 ± 6.90% (P < 0.05). Conclusion: Inchildren with VSD and moderate to severe PH, increased biventricular volume and decreased systolic functionwere observed with RT-3DE, but biventricular systolic function remained within acceptable limits. The childrenin this study recovered well after surgery without serious perioperative complications, suggesting that biventricularsystolic function may help facilitate the surgical decision-making process in children with VSD and moderate-toseverePH.
文摘Objective:To evaluate the effectiveness of discharge planning on maternal caring knowledge,maternal caring behavior,maternal discharge readiness and the rehospitalization of children with ventricular septal defect and pulmonary arterial hypertension(VSD-PAH).Background:Children with congenital heart disease(CHD)with pulmonary arterial hypertension(PAH)have more complications after surgery than those without PAH.Discharge planning is an effective strategy to help children leave the hospital safely,and receive appropriate care after discharge.Methods:A quasi-experimental design was used.Sixty children and their mothers were recruited and divided into two groups:the control group received conventional care,the intervention group received both conventional care and additional discharge planning care.Results:(1)After admission,maternal caring knowledge between the two groups was similar.(2)At discharge,maternal discharge readiness,maternal caring knowledge and maternal caring behavior in the intervention group was significantly higher compared to the control group(t=3.35,p=0.001;F=84.74,p<0.001;F=23.82,p<0.001).This difference persisted after discharge,and was evident at one month and three months after discharge.(3)However,no significant difference in the readmission rate of children after discharge was evident between the two groups.Conclusions:Discharge planning improves the maternal discharge readiness,maternal caring knowledge and maternal caring behaviors.However,this planning did not reduce the readmission rate of children with CHD-PAH.

文摘BACKGROUND The intraoperative management of patients undergoing orthotopic liver transplantation(OLT)frequently encounters hemodynamic instability after reperfusion of the new liver graft.The resulting post-reperfusion syndrome is characterized by an increase in pulmonary vascular resistance and decrease in systemic vascular resistance.In the presence of a left to right intracardiac shunt,this hemodynamic perturbance can lead to shunt reversal followed by hypoxemia and embolization of air and debris into the systemic circulatory system.CASE SUMMARY A 43 years-old male with end-stage liver disease due to primary sclerosing cholangitis complicated by portal hypertension and hepatocellular carcinoma presented for an OLT.A bedside transthoracic echocardiography(TTE)was performed immediately before the procedure and unexpectedly identified a ventricular septal defect(VSD).The patient and the surgical team agreed to proceed with the surgery as it was a time critical donation after circulatory organ death.We developed an intraoperative plan to optimize pulmonary and systemic pressures using vasoactive support,optimized mechanical ventilation,and used transesophageal echocardiography(TEE)for intraoperative monitoring.During reperfusion,considerable turbulent flows with air were noted in the right ventricle,but no air was visualized in the left ventricle.Color flow Doppler showed no reversal flow in the VSD.At the end of the procedure,the patient was extubated in the operating room without complication and was transferred to the transplant unit for recovery.CONCLUSION Our case highlights the importance of echocardiography in the perioperative assessment of patients undergoing liver transplantation.The TTE findings obtained immediately before the procedure and the real-time use of intraoperative TEE to modify our management during the critical phases of the transplant resulted in continuity of care and a good surgical outcome for this patient.

文摘Objective:To evaluate the feasibility,safety and efficacy of transcathcter closure of ventricular septal defect(VSD)in patients with aortic valve prolapse(AVP)and mild aortic regurgitation(AR).Methods:Between January 2008 and July 2014,transcatheter closure of VSD was attempted in 65 patients.Results:The total intermediate closure successful rate in all subjects was 96.9%.During the perioperative period,no death,major bleeding,pericardial tamponade,occluder dislodgement,residual shunt or hemolysis occurred.Two procedures had been forced to suspend due to significant aggregation of device related aortic regurgitation,three cases of transient complete left bundle branch block occurred but did not sustain.At 1-year followup,no patients had residual shunts and complications.Furthermore,grade of residual AR were relieved in 61.9%(39/63)cases and degree of AVP were ameliorated in 36.5%(23/63)patients;Conclusions:Transcatheter closure VSD in selected patients with AVP and mild AR is technically feasible and highly effective.Long term safety and efficacy needs to be assessed.
文摘Objective To evaluate the efficacy of minimally invasive perventricular device closure of ventricular septal defect(VSD). Methods Between September 2011 and February 2013, we collected 40 patients who underwent perventricular closure via a small lower sternal incision(minimally invasive group), aged 15.5±3.5 years(12 months to 32 years) with a body weight of 24.2±7.5 kg(10.8-58.0 kg). The mean size of VSD was 5.6±0.5 mm(2-14 mm). Another 40 patients were included as the surgical group, receiving the conventional surgical repair of VSD. The device of the minimally invasive group was released under the guidance of transesophageal echocardiography. Success rate, cardiac indicators, and clinical outcomes of the 2 groups were compared. Results The patients in the surgical group and those in the minimally invasive group showed similar results in success rate(both 97.5%). The procedure time, intensive care unit stay, hospital stay, and postoperative recovery time in the minimally invasive group were significantly shorter than those in the surgical group(58±21 minutes versus 145±26 minutes, 2±1 days versus 8±3 days, 5±1 days versus 16±6 days, 3±1 days versus 90±20 days, all P<0.05). The minimally invasive group had a higher incidence of conduction anomalies(17.5% versus 2.5%, P<0.05). In the follow-up period of 3-12 months, there was no new residual shunt, noticeable aortic regurgitation, significant arrhythmias, or device failure except for new complications in the surgical group. Conclusions The success rate of minimally invasive perventricular device closure of VSD under transesophageal echocardiography guidance is similar to that of conventional surgical repair, but the short-term outcomes of the minimally invasive approach is much better. Long-term follow-up is necessary to confirm the effectiveness of this technique.

文摘Background: Perimembranous ventricular septal defect combined with right coronary cusp bulge generally should be treated with surgical thoracotomy, owing to the potential aortic regurgitation. However, the minimally invasive method of transcatheter closure has always attracted the attention of cardiologists and patients. The present study aimed to apply transcatheter occlusion in treating ventricular septal defect with right coronary cusp bulge and further evaluate the clinical effect through follow-up. Materials and methods: A total of 40 children diagnosed as having a ventricular septal defect with right coronary cusp bulge, examined using transthoracic echocardiography and cardiovascular angiography, were enrolled in this study. The ventricular septal defects were closed by placing occluders through transcatheter occlusion treatment. During the operation process, the children underwent angiography and transthoracic echocardiography examinations to check the position of the occlude and the extent of aortic regurgitation. The influence of occlusion on the conduction system was evaluated using a surface electrocardiogram. The children were followed up after their procedures. Results: All 40 patients were immediately and successfully occluded. Three patients with filament residual shunts were observed during the operations. No major surgical complications occurred during the perioperative period. During the follow-up period, the positions of all the occluders were good, the residual shunts in the three patients disappeared, and no new or aggravated aortic regurgitation occurred. Electrocardiogram did not reveal any atrioventricular blocks. Only one patient suffered from an incomplete right bundle branch block. Conclusions: Children diagnosed with ventricular septal defect combined with right coronary cusp bulge could be considered for transcatheter occlusion. With appropriate indications and methods, the effect may be favorable.
文摘BACKGROUND The off-label use of various devices has been reported for the transcatheter closure of perimembranous ventricular septal defects(PmVSD) because of serious complications, such as heart block and tricuspid regurgitation(TR),associated with conventional ventricular septal defect devices. However, whether certain defects such as PmVSD with abnormally attached tricuspid are fit for interventional treatment is still disputable.AIM To explore the feasibility and safety of transcatheter closure of PmVSD with abnormally attached tricuspid chordae tendineae using an improved patent ductus arteriosus(PDA) occluder.METHODS We retrospectively analyzed 20 patients diagnosed with PmVSD with abnormally attached tricuspid chordae tendineae who underwent interventional treatment using an improved PDA occluder at our center from January 2012 to January 2016. Baseline characteristics and procedural and follow-up data were analyzed.RESULTS All 20 patients achieved procedure success. No heart block occurred during the operation. One patient had a transient complete right bundle branch block within48 h post-procedure and reverted to normal rhythm after intravenous injections of dexamethasone for 3 d. For all 20 patients, no residual shunt was observed by transthoracic echocardiography post-procedure. During the average follow-up period of 2.4 years, no severe TR was observed.CONCLUSION Using of the improved PDA occluder for the transcatheter closure of PmVSD with abnormally attached tricuspid chordae tendineae is a safe and promising treatment option. However, long-term follow-up in a large group of patients is still warranted.
文摘We performed a retrospective analysis of patients with and without 22q11 deletion undergoing surgery for pulmonary atresia with ventricular septal defect and major aortopulmonary collaterals between January 2004 and August 2009 at our institutions. Information was collected on collateral origin, arch sidedness, presence of central pulmonary arteries, and presence of an aberrant subclavian vessel. While patients with 22q11 deletion were more likely to have collateral origin from brachiocephalic vessels, patients without 22q11 deletion were more likely to have collateral origin from the descending aorta. There was no significant difference in arch sidedness or the presence of central pulmonary arteries. Patients with 22q11 deletion were more likely to have an aberrant subclavian artery (15/46 vs 5/54, p < 0.05), whether a left or right arch was present. Nine of the fifteen 22q11 deletion patients had a collateral originating from an aberrant subclavian artery. In time, genomic and embryologic research may help determine the exact mechanisms by which 22q11 deletion contributes to the development of congenital heart disease such as pulmonary atresia with ventricular septal defect and major aortopulmonary collaterals.
