It has been reported by several authors that a right thoracotomy for mitral valve surgery can be useful after previous coronary aortery bypass grafting (CABG). A 76-year-old man with mitral valve regurgitation after previous CABG underwent mitral valve replacement with some modified techniques. Cardiopulmonary bypass was established with right brachial artery cannulation and right femoral venous cannulation with the aid of vacuum-assisted venous drainage. Ventricular fibrillation (VF) was induced by rapid pacing of the ventricle, and mitral valve replacement was performed under perfused VF with moderate hypothermia. The patient's postoperative course was uneventful. This method appears to be a safe and easy alternative mitral valve surgery for complicated cases of this type.
几位作者报告称，对于先前接受过冠状动脉旁路移植术（CABG）的患者，右胸切口进行二尖瓣手术可能是有用的。一名76岁男性，在先前CABG术后出现二尖瓣反流，采用一些改良技术进行了二尖瓣置换术。借助真空辅助静脉引流，通过右肱动脉插管和右股静脉插管建立体外循环。通过心室快速起搏诱发心室颤动（VF），并在中度低温下在灌注性VF状态下进行二尖瓣置换术。患者术后恢复顺利。对于此类复杂病例，这种方法似乎是一种安全且简便的二尖瓣手术替代方法。
