The hypothesis tested was that left ventricular septal myectomy improved coexisting mitral regurgitation. The pre- and postoperative cine left ventriculograms of 39 patients were compared. The mean difference in time between studies was 15 months. Approximately one half of the patients had a reduction in mitral regurgitation. There was no association between relief of obstructive pressure gradient at rest or with provocation or symptoms and improvement in mitral regurgitation.

检验的假设是左室间隔肌切除术 改善了同时存在的二尖瓣返流。 前和 39例患者术后行左心室电影造影， 比较了 研究之间的平均时间差异为15 个月 大约有一半的患者的 二尖瓣返流 没有任何关联救济之间的 静息或激发时的阻塞性压力梯度，或 二尖瓣返流的症状和改善。
