The objective was to determine which factors might help to predict the need for mechanical right ventricular support following insertion of a left ventricular assist device (LVAD). A retrospective analysis was performed on 24 patients with cardiomyopathies who had insertion of a LVAD as a bridge to heart transplantation at Presbyterian University Hospital during the period 1987 to 1991. Group 1 consisted of 18 patients who could be adequately supported with the LVAD alone, while Group 2 consisted of 6 patients who required additional support with a right ventricular assist device. Group 2 exhibited longer periods of hypotension on cardiopulmonary bypass, increased inotropic support and decreased right ventricular ejection fraction at time of chest closure post-LVAD.
目的是确定哪些因素可能有助于预测在植入左心室辅助装置(LVAD)后对机械性右心室支持的需求。对1987年至1991年期间在长老会大学医院接受LVAD植入作为心脏移植桥梁的24例心肌病患者进行了回顾性分析。第1组由18例仅用LVAD就能得到充分支持的患者组成,而第2组由6例需要右心室辅助装置额外支持的患者组成。第2组在体外循环期间出现低血压的时间更长,在LVAD植入后关闭胸腔时,正性肌力支持增加,右心室射血分数降低。
