We performed a transsubxiphoidal LV puncture (TSLVP) to evaluate left ventricular function in 21 patients with both mechanical prosthetic aortic and mitral valves and successfully obtained hemodynamic information on each patient. Analyzing cardiac hemodynamic information and ventriculographic findings obtained with TSLVP, we concluded that seven of the patients required repair of their prosthetic valves. Five of these seven patients agreed to replacement of their valves, whereas two did not. TSLVP was performed adequately and safely without severe complications, suggesting that this maneuver is easier than that of transapical LV puncture and should be recommended for the assessment of left ventricular hemodynamic functions instead of the transapical LV puncture, especially in patients requiring replacement of two valves.
我们对21例同时患有机械主动脉瓣和二尖瓣置换术的患者进行了经剑突下心室穿刺（TSLVP）以评估左心室功能，并成功获取了每位患者的血流动力学信息。通过分析TSLVP获得的心脏血流动力学信息和心室造影结果，我们得出结论，其中7例患者需要修复其人工瓣膜。这7例患者中有5例同意更换瓣膜，而2例不同意。TSLVP操作充分且安全，无严重并发症，这表明该操作比经心尖心室穿刺更容易，应推荐用于评估左心室血流动力学功能，而不是经心尖心室穿刺，尤其是在需要更换两个瓣膜的患者中。
