title: Transatrial repair of submitral left ventricular pseudoaneurysm.
abstract: In a 57-year-old man with Wolff-Parkinson-White syndrome, a left ventricular pseudoaneurysm developed, induced by the pop phenomenon, after radiofrequency catheter ablation of the posterolateral accessory pathway. The pseudoaneurysm was positioned at the atrioventricular groove with moderate pericardial adhesions, and the rupture site was located just below the P3 annulus of the posterior mitral leaflet. With this anatomy and in the presence of adhesions, we repaired the rupture site from within the heart through an incision made in the posterior mitral leaflet. This transmitral approach might be a reasonable surgical option for treating this type of submitral left ventricular pseudoaneurysm.
