Although biventricular heart failure has been successfully managed with dual continuous-flow ventricular assist devices, the long-term use of 2 mechanically dissimilar pumps has traditionally been discouraged. We present the case of a 52-year-old man whose treatment with a HeartMate II left ventricular assist device was complicated by right ventricular failure, necessitating the implantation of a long-term right ventricular assist device. A HeartWare left ventricular assist device was placed along the right ventricular base to avoid interference with the HeartMate II housing. The patient was discharged from the hospital after routine postoperative care and dual-device training. This case shows that, despite logistical complexities, nonidentical continuous-flow device pairings can successfully provide long-term biventricular support.
尽管双心室心力衰竭已通过双连续流心室辅助装置成功得到控制，但传统上不鼓励长期使用两种机械结构不同的泵。我们报告一例52岁男性患者，其接受HeartMate II左心室辅助装置治疗后并发右心室衰竭，因此需要植入长期右心室辅助装置。将HeartWare左心室辅助装置放置在右心室基部，以避免干扰HeartMate II的外壳。患者在接受常规术后护理和双装置训练后出院。该病例表明，尽管存在后勤方面复杂性，但不同的连续流装置配对仍可成功提供长期双心室支持。
