With the use of the superior transseptal approach during mitral valve surgery, good exposure of the mitral valve can be achieved with simple traction sutures, which minimize the risk of deformation of the mitral valve. For this reason, we routinely perform mitral valvoplasty using the superior transseptal approach; however, we, occasionally encounter cases that develop postoperative atrial dysrhythmia. We have therefore, devised a very simple technique for preservation of the sinus node artery in the superior transseptal approach, which is effective for reducing the incidence of postoperative sinus node dysfunction. In this technique, during incision of the dome of the left atrium, the sinus node artery is carefully dissected and preserved.
在二尖瓣手术中采用经房间隔上入路时，使用简单的牵引缝线就能很好地暴露二尖瓣，这将二尖瓣变形的风险降至最低。因此，我们常规采用经房间隔上入路进行二尖瓣成形术；然而，我们偶尔会遇到术后发生房性心律失常的病例。因此，我们设计了一种在经房间隔上入路中保留窦房结动脉的非常简单的技术，这对于降低术后窦房结功能障碍的发生率是有效的。在这项技术中，在切开左心房顶部时，要仔细解剖并保留窦房结动脉。
