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.
在一名患有预激综合征的57岁男性患者中，在对后外侧旁路进行射频导管消融后，因“弹出”现象诱发了左心室假性动脉瘤。假性动脉瘤位于房室沟，伴有中度心包粘连，破裂部位位于二尖瓣后叶P3瓣环下方。鉴于这种解剖结构以及存在粘连的情况，我们通过在二尖瓣后叶做切口，从心脏内部修复了破裂部位。这种经二尖瓣入路可能是治疗此类二尖瓣下左心室假性动脉瘤的一种合理手术选择。
