A rare case of left atrial dissection after mitral valve replacement is reported. Low output syndrome developed in the immediate postoperative period. Cardiac catheterization showed marked elevation of the pulmonary wedge pressure, and left ventriculography revealed massive paraprosthetic leakage with left atrial dissection. At the reoperation, the dissecting cavity was successfully closed from inside the left atrium under cardiopulmonary bypass. We consider this complication another variation of an atrioventricular discontinuity after mitral valve replacement.
报告了1例二尖瓣置换术后左心房夹层的罕见病例。术后即刻出现低心排血量综合征。心导管检查显示肺楔压显著升高，左心室造影显示人工瓣膜周围大量漏血伴左心房夹层。再次手术时，在体外循环下经左心房内部成功封闭了夹层腔。我们认为这种并发症是二尖瓣置换术后房室不连续的另一种变异形式。
