We describe successful use of a minimal extracorporeal circulation circuit (MECC) as an alternative to conventional cardiopulmonary bypass (CPB) for the implantation of left ventricular assist device (LVAD) in a 65-year-old patient with ischemic dilated cardiomyopathy. A Jarvik 2000 was implanted through a median sternotomy with the outflow graft anastomosed to the ascending aorta. MECC circuit provides optimal circulatory support throughout the procedure and prevents hemodynamic instability caused by marked displacement of the heart for exposure of the left ventricular apex, while minimizing the adverse effects of conventional CPB.
我们成功地使用了一种最小体外循环回路（MECC）作为替代传统心肺旁路（CPB）的方法，为一名 65 岁患有缺血性扩张型心肌病的患者植入左心室辅助装置（LVAD）。通过正中胸骨切开术植入了一个 Jarvik 2000 型装置，流出移植物与升主动脉吻合。MECC 回路在整个手术过程中提供了最佳的循环支持，并防止了由于心脏明显移位以暴露左心室心尖而导致的血液动力学不稳定，同时最大限度地减少了传统 CPB 的不良影响。
