Five patients with the left-sided or intermediate type (Lev) of the Taussig-Bing anomaly were found to have an associated straddling of the mitral valve. In four patients the anomaly of the mitral valve was not recognized preoperatively, and all four died postoperatively. The persistent subpulmonic obstruction caused by the abnormal attachment of the anterior mitral leaflet is considered a significant factor in the poor operative outcome. Retrospective study of angiograms in these four patients revealed diagnostic clues of straddling mitral valve which enabled us to diagnose a fifth patient angiographically and confirm the diagnosis by cross-sectional echocardiography. A surgical approach to correct this association of abnormalities is proposed which avoids operating upon the mitral valve. Its function is thereby preserved, yet the hemodynamic problem caused by the straddling is bypassed. The fifth patient in this series was successfully treated by the proposed operative method.
发现5例陶西格-宾畸形左侧型或中间型（Lev型）患者合并二尖瓣骑跨。4例患者术前未识别出二尖瓣异常，均于术后死亡。二尖瓣前叶异常附着导致的持续性肺下梗阻被认为是手术效果不佳的重要因素。对这4例患者血管造影的回顾性研究揭示了二尖瓣骑跨的诊断线索，使我们能够对第5例患者进行血管造影诊断，并通过横断面超声心动图证实诊断。提出了一种纠正这种异常关联的手术方法，该方法避免对二尖瓣进行手术。从而保留了其功能，但绕过了由骑跨引起的血流动力学问题。该系列中的第5例患者通过所提出的手术方法成功治愈。
