左心室辅助装置(LVAD)越来越多地植入晚期心力衰竭患者,以提高生存率和生活质量,无论是作为移植的桥梁,康复的桥梁还是作为目的地治疗。由于左心室的机械卸载,LVAD治疗通常伴随着肺动脉压的大幅降低。LVAD植入后持续性肺动脉高压(PH)增加了右心室衰竭(RVF)的风险。在这种情况下,肺血管扩张剂已被应用:a)作为减少后负荷和在术后早期使RVF患者脱离正性肌力药物的策略,B)作为旨在优化右心血流动力学和预防晚期RVF的长期治疗,以及c)为了降低LVAD后持续升高的肺动脉压(PAP)和肺血管阻力(PVR),使心脏移植成为候选。然而,这些战略和做法的风险和效益存在相当大的不确定性,各机构之间的差异很大。本文综述了LVAD患者使用肺血管扩张剂的现有证据和建议。
Left ventricular assist devices (LVAD) are increasingly implanted in advanced heart failure patients to improve survival and quality of life either as a bridge to transplant, bridge to recovery or as destination therapy. LVAD therapy is often accompanied by a profound lowering of pulmonary artery pressure due to mechanical unloading of the left ventricle. Persistent pulmonary hypertension (PH) after LVAD implantation increases the risk of right ventricular failure (RVF). In this context pulmonary vasodilators have been implemented: a) as a strategy to reduce afterload and wean patients with RVF from inotropes in the early postoperative period, b) as long-term therapy aiming to optimize right heart hemodynamics and prevent late RVF and c) in order to lower persistently elevated pulmonary artery pressure (PAP) and pulmonary vascular resistance (PVR) after LVAD and enable candidacy for heart transplantation. However, considerable uncertainty exists regarding the risks and benefits of these strategies and practices vary widely among institutions. This article provides an overview of the available evidence and existing recommendations regarding the use of pulmonary vasodilators in LVAD recipients.
