Single puncture approach guided by transesophageal echocardiography for atrial fibrillation ablation in a patient with prior percutaneous septal closure: case report.

ABSTRACT:

Background

Atrial septal defect (ASD) is associated with a risk of developing atrial fibrillation (AF) higher than in the general population, even after percutaneous or surgical septal closure. Catheter ablation is an effective treatment strategy for preventing recurrences and reducing the AF burden. However, electrophysiologists are faced with technical difficulties and the risk of complications with the left atrium access in patients with prior ASD percutaneous closure.

Case summary

We report a case of a patient with highly symptomatic paroxysmal AF, with an ASD, closed percutaneously many years before, who underwent a successful catheter AF ablation, using a single transeptal (TSP) approach guided by transesophageal echocardiography (TEE).
