Acute right ventricular failure after cardiac surgery occurring in the first postoperative hours is associated with a bad prognosis. We have used a centrifugal pump either for left, right or biventricular assistance. However, the use of this device for pure right ventricular assistance is rare. We report a 30 year-old female undergoing a mitral valve replacement and a 42 year-old male undergoing a cardiac transplantation, who had a successful right ventricular assistance using a centrifugal pump, due to a failing right ventricle, as the result of insufficient myocardial protection and severe pulmonary hypertension. These two cases illustrate the value of the mechanical ventricular assist device for the treatment of right heart failure.
心脏手术后数小时内发生的急性右心室衰竭预后不良。我们使用离心泵进行左心室、右心室或双心室辅助。然而，将该装置用于单纯右心室辅助的情况很少见。我们报告了一名30岁接受二尖瓣置换术的女性和一名42岁接受心脏移植的男性，由于心肌保护不足和严重肺动脉高压导致右心室衰竭，他们使用离心泵成功进行了右心室辅助。这两个病例说明了机械心室辅助装置在治疗右心衰竭方面的价值。
