The presence of mechanical heart valves in both aortic and mitral positions is a significant limitation for traditional left ventricular (LV) access, including retrograde transaortic and/or antegrade interatrial transseptal routes. We present a case of successful catheter ablation for ventricular tachycardia via a traditional transfemoral venous approach, which involves direct puncture of the inferior and medial aspect of the right atrium adjacent to the posteroseptal process of LV (PSPLV). Percutaneous trans-right atrial access to the left ventricle appears to be a safe and feasible method for catheter ablation of ventricular tachycardia in patients with mechanical aortic and mitral valves.
主动脉瓣和二尖瓣位置存在机械心脏瓣膜是传统左心室（LV）入路的重大限制，包括逆行经主动脉和/或顺行房间隔经中隔途径。我们报告了一例通过传统经股静脉途径成功进行的室性心动过速导管消融病例，该途径涉及直接穿刺右心房的下内侧和毗邻 LV 后间隔突起（PSPLV）的部位。经右心房穿刺入左心室似乎是一种安全可行的方法，可用于患有机械性主动脉瓣和二尖瓣的患者的室性心动过速导管消融。
