Abstract

Assist devices have become available for the treatment of right ventricular (RV) failure. The present study assesses the efficacy of pulmonary artery balloon counterpulsation (PABC) in restoring RV output to normal levels. In a porcine model of RV failure during left heart bypass, PABC restored RV output to normal, provided that the RV output was not depressed to less than 50% of baseline values. When RV failure was more severe, PABC was not effective in restoring RV output to base line. This study suggests that a rational approach should be developed for the use of right heart assist devices. In moderately severe RV failure, PABC may be successful in restoring cardiac output to normal. However, in extreme failure a right heart bypass is necessary.

摘要

辅助装置已可用于治疗右心室（RV）衰竭。本研究评估肺动脉球囊反搏（PABC）将右心室输出恢复到正常水平的疗效。在左心旁路手术期间的猪右心室衰竭模型中，只要右心室输出不降至低于基线值的50%，PABC就能将右心室输出恢复到正常水平。当右心室衰竭更严重时，PABC无法有效将右心室输出恢复到基线水平。本研究表明，应制定合理的方法来使用右心辅助装置。在中度严重的右心室衰竭中，PABC可能成功地将心输出量恢复到正常水平。然而，在极度衰竭时，右心旁路手术是必要的。
