The early postoperative care of a heart transplant recipient remains challenging, even in experienced centers with a long tradition of excellence. Approximately 10% to 20% of heart transplant recipients experience potentially life-threatening right ventricular dysfunction intraoperatively and early postoperatively due to an elevated pulmonary vascular resistance. In addition, heart transplant recipients experience a high risk of perioperative hemorrhage, as well as opportunistic infection and rejection. The authors describe a case of severe right ventricular dysfunction in a 46-year-old male several hours after heart transplantation for a dilated cardiomyopathy. This patient was salvaged by judicious multimodality therapy including the use of adrenergic agents, phosphodiesterase inhibitors, inhaled nitric oxide, and extracorporeal membrane oxygenation. The risk factors for the development of early graft failure after heart transplantation are reviewed, along with the principles of appropriate management of this complication.
心脏移植受者的术后早期护理仍然具有挑战性,即使在有着长期卓越传统的经验丰富的中心也是如此。由于肺血管阻力升高,约10%至20%的心脏移植受者在术中及术后早期会出现可能危及生命的右心室功能障碍。此外,心脏移植受者围手术期出血风险高,还存在机会性感染和排斥反应。作者描述了一例46岁男性在因扩张型心肌病接受心脏移植数小时后出现严重右心室功能障碍的病例。该患者通过明智的多模式治疗得以挽救,包括使用肾上腺素能药物、磷酸二酯酶抑制剂、吸入一氧化氮和体外膜肺氧合。本文回顾了心脏移植后早期移植物功能衰竭发生的危险因素,以及该并发症的适当处理原则。
