Left atrial reduction is a surgical procedure designed in order to eliminate the chronic atrial fibrillation caused by mitral valve disease. However, this surgical technique is not high-risk free. Since a mount of tissue is excised from the left atrium, misalignment of the left atrium can be present. Bleeding of the posterior suture line in this chamber, as well as injury of the circumflex coronary artery may be fatal complications of this technique. Partial heart autotransplantation offers a good solution allowing an excellent visual operative field. The circumflex coronary artery is under direct vision while performing the anastomosis of the left atrium, and the suture line becomes safer and easier.
左心房缩小术是一种旨在消除由二尖瓣疾病引起的慢性心房颤动的外科手术。然而，这种手术技术并非毫无风险。由于要从左心房切除一定量的组织，可能会出现左心房排列不齐的情况。该腔室后缝合线出血以及回旋支冠状动脉损伤可能是这种技术的致命并发症。部分心脏自体移植提供了一个很好的解决方案，可获得极佳的手术视野。在进行左心房吻合术时，回旋支冠状动脉处于直视之下，缝合线变得更安全、更容易。
