We report intermittent mitral valve regurgitation with 17 acute pulmonary edemas over a 16-month period after aortic valve replacement due to combined aortic valve disease in a 51-year-old man. The mechanism of mitral regurgitation was explained by the relatively large size of the prosthetic valve which had had to be sutured partly below the aortic annulus. It was suspected to interfere with the closure of the mildly diseased mitral valve when under pressure or subjected to volume loadings of the left ventricle which provoked free mitral regurgitation. There was no recurrence of pulmonary edema in the 50 months following mitral valve replacement.
我们报告了一名51岁男性，因合并主动脉瓣疾病行主动脉瓣置换术后16个月内出现间歇性二尖瓣反流，并伴有17次急性肺水肿。二尖瓣反流的机制是由于人工瓣膜尺寸相对较大，不得不部分缝合在主动脉瓣环下方。怀疑在左心室受压或承受容量负荷时，人工瓣膜会干扰轻度病变二尖瓣的关闭，从而引发二尖瓣反流。二尖瓣置换术后50个月内未再出现肺水肿。
