AF is often found in association with an ASD.

There are an increasing number of patients undergoing transcatheter closure of an
ASD who subsequently develop AF in clinical practice.

Catheter ablation has emerged as an effective treatment strategy for drug-refractory
symptomatic AF.

While transseptal access to the left atrium (LA) is a prerequisite for AF ablation,
it may prove difficult in the presence of an ASD closure device.

Anticipating technical difficulties and potential complications may discourage operators
from considering catheter ablation of AF in this particular patient population. Herein,
we describe our experience with TSP in patients with prior implantation of an ASD
closure device.Abbreviations:
AF (atrial fibrillation), ASD (atrial septal defect), ICE (intracardiac echocardiography), LA (left atrium/atrial), PCI (percutaneous coronary intervention), PV (pulmonary vein), PVI (pulmonary vein isolation), TSP (transseptal puncture)Keywords
