Transcatheter closure of congenital perimembranous ventricular septal defect using the Amplatzer duct occluder 2.

Objective: The objective of this study was to explore the clinical effect of the transcatheter closure of congenital perimembranous ventricular septal defect using the Amplatzer duct occluder 2.

Methods: Between February 2012 and December 2016, 51 patients were subjected to Amplatzer duct occluder 2 for transcatheter closure of perimembranous ventricular septal defect. A total of 51 patients with perimembranous ventricular septal defect who underwent transcatheter closure by the conventional membranous ventricular septal occluder comprised the control group.

Postprocedural Outcomes and Risk Factors for Arrhythmias Following Transcatheter Closure of Congenital Perimembranous Ventricular Septal Defect: A Single-center Retrospective Study.

Background: Currently, transcatheter closure of perimembranous ventricular septal defect (pmVSD) is a widely accepted therapeutic modality. However, arrhythmias, especially postprocedural heart blocks, are a concern and outcomes are not very clear. This study explored the outcomes and risk factors of arrhythmias associated with transcatheter device closure of pmVSD.
