Key result
Pulmonary vein isolation in a 24-year-old patient with persistent atrial fibrillation and a dilated right atrium revealed sustained pulmonary vein tachycardia as a major AF substrate.
Case Report (n=1)
Sustained pulmonary vein tachycardia may serve as a major substrate for maintaining persistent atrial fibrillation in young patients with repaired congenital heart disease.
May implicate sustained PV tachycardia in persistent AF among young CHD patients; hypothesis-generating and requires validation before clinical adoption.
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.

Izumi et al. (2016) conducted a case report in Persistent Atrial Fibrillation (n=1). Pulmonary vein isolation was evaluated on Sustained pulmonary vein tachycardia. Pulmonary vein isolation in a 24-year-old patient with persistent atrial fibrillation and a dilated right atrium revealed sustained pulmonary vein tachycardia as a major AF substrate.
