The mitral valve was approached through a modified incision in the roof of the left atrium in 100 consecutive patients to study exposure of the valve, complications of the method and the incidence of dysrhythmia. There were five deaths: one related to difficult atrial closure and another to breakdown of the atrial suture line. Two major and two minor non-fatal haemorrhagic complications occurred. Exposure of the valve was found to be superior to that of conventional atrial incisions in the great majority of cases. When comparing the incidence of perioperative dysrhythmia in our 100 patients with that of 56 patients approached through the conventional atrial incisions, no significant differences were found even though the sinus node artery is likely to be divided when incising the roof of the left atrium.
对连续100例患者通过改良的左心房顶部切口显露二尖瓣，以研究瓣膜显露情况、该方法的并发症及心律失常的发生率。有5例死亡：1例与心房关闭困难有关，另1例与心房缝线处裂开有关。发生了2例严重和2例轻微的非致命性出血并发症。发现在绝大多数病例中，该瓣膜显露方法优于传统的心房切口。将我们这100例患者围手术期心律失常的发生率与通过传统心房切口入路的56例患者进行比较时，尽管切开左心房顶部时可能会切断窦房结动脉，但未发现显著差异。
