Mitral valve replacement was performed through a right thoracotomy using femorofemoral bypass under profound systemic hypothermia in a 62-year-old man who had undergone coronary artery bypass grafting using both internal thoracic arteries. The right thoracotomy approach minimizes the risk of injury to the arterial grafts, and deep hypothermia obviates the need to interrupt the grafts to administer cardioplegia. This technique provides excellent exposure of the mitral valve while minimizing the operative risk.
在一名62岁男性患者中，采用右胸切口，在全身深度低温下使用股-股体外循环进行二尖瓣置换术，该患者曾使用双侧胸廓内动脉进行冠状动脉旁路移植术。右胸切口入路可将动脉移植物损伤风险降至最低，而深度低温可避免为施行心脏停搏而中断移植物。该技术能在将手术风险降至最低的同时，极好地显露二尖瓣。
