Twenty patients underwent mitral valve replacement or other surgical procedures within the left atrium with Dubost's transseptal left atriotomy. The left atrium was grossly enlarged in six patients. Exposure was considered to be excellent in 13 patients and poor in only two. One patient (with a second aortic and mitral valve replacement) required a permanent pacemaker after operation, none had a residual shunt at the atrial level, and none required reoperation for bleeding. The Dubost transseptal left atriotomy affords excellent exposure of left atrial structures, is easy to close, and does not increase the prevalence of postoperative rhythm disturbances.
20例患者采用杜博斯特经房间隔左心房切开术进行二尖瓣置换或左心房内的其他外科手术。6例患者左心房明显扩大。13例患者的手术视野被认为极佳，只有2例较差。1例患者（接受二次主动脉瓣和二尖瓣置换）术后需要永久起搏器，无一例在心房水平有残余分流，也无一例因出血需要再次手术。杜博斯特经房间隔左心房切开术能很好地暴露左心房结构，易于关闭，且不会增加术后心律失常的发生率。
