Permanent Atrial Fibrillation is Restored And Sinus Rhythm Maintained Without Catheter Ablation After Atrial Septal Defect Closure: A Case Report

Abstract

Giant atrial septal defect (ASD) often is associated with atrial arrhythmia, such as atrial fibrillation (AF). The recovery rate of AF is very low. Moreover, it is difficult for the intervention of a giant atrial septal defect, and it also is more difficult to perform atrial septal puncture and left atrial appendage (LAA) closure after ASD occlusion. Here, we report a case of a giant ASD and permanent AF. We find that the AF is significantly improved after atrial septal defect (ASD) occlusion and left atrial appendage (LAA) occlusion, which is manifested by spontaneous restoration and maintenance of normal sinus rhythm.
