Objectives:To access the effectiveness of our modified right-ventricular overhauling procedure on tricuspid valve(TV)growth in patients with pulmonary atresia with intact ventricular septum(PAIVS).Methods:We retrospectively reviewed 21 patients with PAIVS who underwent modified right ventricular overhauling(mRVoh)between 2008 and 2019 at two institutions.Our mRVoh consisted of wide resection of hypertrophied infundibular and trabecular muscle,peeling off fibrotic endocardial tissue in the right ventricle(RV)cavity,surgical pulmonary valvotomy,and Blalock-Taussig shunt or banding of ductus arteriosus under cardiopulmonary bypass.The TV annulus sizes were measured and analyzed using echocardiography before and after mRVoh.Results:No mortalities were observed during a median follow-up of 3 years(interquartile range:1.3–4.7 years)of follow-up were noted.mRVoh was performed at a median age of 163.5 days(range:21–560 days),including seven neonates and two infants(<60 days).During follow-up,the median TV annular z-score increased significantly from−2.24 to−1.15 before and after mRVoh(p=0.004).In ten patients with a prior history of percutaneous interventions for RV outflow tract(RVOT)widening at least 6 months before mRVoh,the TV annular z-score significantly changed during the period after mRVoh(−2.03 to−1.61,p=0.028)compared with the period before mRVoh(−2.51→–2.03,p=0.575)after percutaneous intervention only.Conclusions:mRVoh in PAIVS patients was positively associated with TV annular growth,and it was more effective than percutaneous RVOT widening interventions without mRVoh. 展开更多
