超声心动图评估左心室辅助装置对围手术期右心室功能的影响

Echocardiography in evaluating effect of left ventricular assist devices on perioperative right ventricular function

终末期心力衰竭(HF)是心脏病发展到终末阶段的临床综合征,发病率和死亡率均较高。心脏移植是目前公认的治疗终末期HF的唯一有效手段,但心脏供体严重不足,使得左心室辅助装置(LVAD)成为治疗终末期HF的重要手段。右心室衰竭是植入LVAD后常见并发症,早期诊断植入LVAD后右心室衰竭是重要临床问题。本文对超声心动图评估植入LVAD围手术期右心室功能研究进展进行综述。

End-stage heart failure(HF)is a clinical syndrome in various heart diseases developed to end-stage with high morbidity and mortality.Heart transplantation is deemed as the only valid method for sufferers with end-stage HF,but implantation of left ventricular assist device(LVAD)has become an important treatment for HF patients at the end-stage for the critical shortage of cardiac donors.Right ventricular failure frequently occurred after LVAD implantation.Early identifying right ventricular failure after LVAD implanted has been an important clinical problem.The research progresses of echocardiography for evaluation on right ventricular function perioperative LVAD implantation were reviewed in this article.
