Pulmonary Vein Tachycardia after Pulmonary Vein Isolation fo
Abstract
The substrate for atrial fibrillation (AF) in young patients with congenital heart disease could be heterogeneous. We report a 24-year old patient with persistent AF having the dilated right atrium following surgical repair of congenital heart disease demonstrating sustained pulmonary vein tachycardia (PVT) after pulmonary vein isolation. The sustained PVT could have been a major substrate for the maintenance of AF in this young patient.

Case Report
The substrate for atrial fibrillation (AF) in young patients with repaired congenital heart disease could be heterogeneous. Here we report for the first time a 24-year old patient demonstrating sustained pulmonary vein tachycardia (PVT) after pulmonary vein isolation (PVI) for persistent AF. He underwent the patch closure for atrial septal defect (ASD) and the commissurotomy for valvular pulmonary stenosis when he was 1 year old. The echocardiography revealed no dilation of the left atrium (parasternal dimension 33 mm). As shown in Figure 1 (inset), the right atrium was dilated due to residual regurgitation from the repaired pulmonary and dysplastic tricuspid valves. He had a history of typical atrial flutter (AFL) when he was 18 years old, and spontaneous transition to AF was observed at the age of 20 years....
