Hemodynamic assessment of patients with prosthetic valves can be challenging. Noninvasive techniques may be limited by interference from the prosthetic material, whereas access to the left ventricle for direct pressure measurements often is not possible using common methods. The technique of direct, percutaneous left ventricular puncture has been proven to be a safe method that often provides needed data to help manage difficult clinical situations. We report our 8-yr experience with this technique for assessment of patients with valvular prostheses. Direct left ventricular puncture is a safe technique in patients with prior cardiac surgery and provided significant diagnostic information in the set of patients with multiple valvular prostheses.
人工瓣膜患者的血流动力学评估可能具有挑战性。非侵入性技术可能会受到人工瓣膜材料干扰的限制，而使用常规方法通常无法进入左心室进行直接压力测量。经皮直接左心室穿刺技术已被证明是一种安全的方法，它常常能提供所需数据以帮助处理棘手的临床情况。我们报告了我们使用该技术评估瓣膜置换患者的8年经验。直接左心室穿刺对于曾接受心脏手术的患者是一种安全的技术，并且为患有多个人工瓣膜的患者群体提供了重要的诊断信息。
