- Abstract: OBJECTIVE: To evaluate the the effect and prognosis of transcatheter device closure for perimembranous ventricular septal defects(PmVSDs)with aortic valve prolapse(AVP). METHODS: The clinical data of 1108 patients who underwent percutaneous closure from January 2011 to January 2017 were collected to conduct this retrospective study,mainly including transthoracic echocardiography,digital subtraction angiography data,occluder type and sociodemographic information(age,weight and gender). T-test and Mann-Whitney U test were used to compare group measurement data. Wilcoxon signed rank test was used for the nonnormal distribution of paired design data. Fisher exact test was used for the four fold table. Monte Carlo approximation exact probability method was used for the R×C table.Multiple Logistic-regression analysis was used to estimate the risk factors of AR. RESULTS: Compared with 10(0.9%)of1053 patients without AVP,8(14.5%)of the 55 children with preoperative AVP presented aggravated postoperative aortic regulation(AR)and AR usually occurred in the long-term follow-up(>1 year). None of the AR progressed to moderate or severe. There were no significant changes in left ventricular ejection fraction,left ventricular shortening rate or AR before and after interventional operation in PmVSDs with AVP. CONCLUSION: Percutaneous closure for ventricular septal defect combined with AVP is an effective alternative to surgery when using appropriate occluders,meeting related standards and operated in an experienced cardiovascular center.
