Why the study?
Techniques are needed to perform a transeptal puncture safely and effectively in patients postimplantation of an atrial septal defect occluder to facilitate catheter ablation of atrial arrhythmias.
Provides technical guidance on performing transseptal puncture in patients with existing ASD occluders who require catheter ablation.
Supports feasibility of post-ASD-occluder ablation; leaves open need for prospective validation before wider adoption.
The management of atrial septal defects (ASDs) has been revolutionized by the advent of percutaneous transvenous occlusion devices. This case series describes techniques required to perform a transeptal puncture safely and effectively in patients postimplantation of an atrial septal defect occluder to facilitate catheter ablation of atrial arrhythmias.
