Transcatheter closure of perimembranous and muscular ventricular septal defects: short and medium-term outcome

Abstract

Transcatheter closure of perimembranous and muscular ventricular septal defects: short and medium-term outcome ABSTRACT Objective: This study attempted to report the initial results: the safety and efficacy of transcatheter closure of ventricular septal defects (VSDs) at Hue Central Hospital with the short and medium-term follow-up. Methods: From September 2012 to May 2017, a total of 36 patients with perimembranous or muscular VSD underwent an attempt of transcatheter closure at the Department of Interventional Cardiology, Hue Central Hospital. Results: 14 males and 26 females participated in this study, with the age of 17,29  13.72 and 24.23  12.32 respectively. Among these patients, 19.44% of them were under 6-year-old; 72.22% had perimembranous VSDs, 27.78% had muscular VSDs, and 33.33% had aneurysm. The distance to AV was 5.62 ± 4.32 mm. The device size was 15.31± 8.12 mm. Procedures lasted for 57.17 ± 26.5 min with 15.31± 8.12 min of exposure. The complete closure rates by transthoracic echocardiography after 24 hours, 1 month, 3 months and 6 months (transthoracic) were 94.44%; 94.44% ; 97.22% and 100%, respectively. Mean time of follow-up was 11.92 ± 8.36 (3-38) months. Success rate was 97.22% and no death occurred. There was 1 case of hematuria, lasting 1 month; no Atrioventricular (AV) block. Conclusions: Transcatheter closure of VSDs is a novel, feasible and safe technique with high success rate (97.22%). The transcather approach provides a less invasive alternative than surgical closure and might become the first choice treatment in selected patients.
