Left ventricular outflow tract obstruction after mitral valve replacement may occur when a retained native anterior leaflet prolapses between prosthetic struts. Existing reports of left ventricular outflow tract obstruction by this mechanism lack emphasis on its surgical treatment. We obtained definitive relief of left ventricular outflow tract obstruction by transaortic exposure, division, and partial excision of the obstructing leaflet. This approach minimizes the complexity and potential morbidity of the correction.
二尖瓣置换术后左心室流出道梗阻可能在保留的天然前叶在人工瓣膜支柱之间脱垂时发生。现有关于这种机制导致左心室流出道梗阻的报道缺乏对其手术治疗的重视。我们通过经主动脉暴露、切开并部分切除梗阻叶，使左心室流出道梗阻得到了确切缓解。这种方法将矫正的复杂性和潜在发病率降至最低。
