Infl uence of percutaneous transcatheter closure of an atrial septal defect on the atrioventricular conduction

Abstract

ASD patients presented with significantly longer PR interval than PFO patients before closure. In contrast with the PFO group, the PR interval increased in the ASD group after medium-term follow-up. These findings indicate the need for further follow-up after ASD repair in order to detect potential late AVCD.

Amplatzer occluder versus CardioSEAL/STARFlex occluder: a meta-analysis of the efficacy and safety of transcatheter occlusion for patent foramen ovale and atrial septal defect

“…[2][3][4] Therefore, occlusion may not be necessary for all patients with patent foramen ovale or atrial septal defect, as some may suffer from its complications, including peripheral embolism, thrombosis, and arterial hypertension. 5,6 Moreover, if the patients are troubled with coronary artery disease, arrhythmia, or diabetes, the patent foramen ovale or atrial septal defect may lead to a higher incidence of major cardiovascular complications. Patients are only considered to receive an intervention in cases of cryptogenic stroke or thrombotic attacks.…”
