Key result
Pulmonary vein antrum isolation successfully treated paroxysmal atrial fibrillation without resection of the giant left atrial appendage, with only one episode of AF in 17 months follow-up.

Does percutaneous pulmonary vein antrum isolation prevent atrial fibrillation recurrence in a patient with paroxysmal atrial fibrillation and a congenital giant left atrial appendage?
Percutaneous pulmonary vein antrum isolation can successfully treat paroxysmal atrial fibrillation in patients with a congenital giant left atrial appendage without requiring surgical resection.
May support PVI without resection in giant LAA; hypothesis-generating and should not yet change practice.
A congenital giant left atrial appendage (LAA) is a rare condition only described in case reports [1]. Supraventricular tachycardias, including atrial fibrillation (AF), and systemic embolisation are the most common clinical findings [1, 2]. Almost all reported cases are treated by resection of the giant LAA [1]. A few cases are treated conservatively [3, 4]. Catheter ablation has not been reported as a treatment option. For the first time, we present a patient with paroxysmal AF and a congenital giant LAA who was successfully treated by percutaneous pulmonary vein antrum isolation (PVAI).

Hof et al. (2011) conducted a case report in Atrial fibrillation with a giant left atrial appendage (n=1). Pulmonary vein antrum isolation (PV AI) was evaluated on Recurrence of atrial fibrillation post-procedure. Pulmonary vein antrum isolation successfully treated paroxysmal atrial fibrillation without resection of the giant left atrial appendage, with only one episode of AF in 17 months follow-up.
