Although left ventricular assist device (LVAD) implant is associated with an increased survival in patients with end-stage heart failure, severe right ventricular failure requiring a right ventricular assist device (RVAD) placement is associated with increased short-term morbidity and mortality. Patients not eligible for transplant have limited options, which may impact decision-making and outcomes at nontransplant centers. We conducted a retrospective review of all LVAD implants at our nontransplant center. Primary stratification was by the need for a postoperative RVAD implant. The primary outcome was survival. The Cox proportional hazards regression modeling was used to further evaluate mortality. From 2017 to 2022, 128 patients underwent a primary LVAD implant and 24 (18.75%) required a perioperative RVAD placement. RVAD implant was associated with increased operative mortality (1.92% vs 33.33%, p <0.01) and decreased 1-year (91.29% vs 60.60%, p <0.01) and 2-year survival (84.05% vs 36.36%, p <0.01). However, in patients who survived their index hospitalization, 1-year (93.00% vs 91.67%, p = 0.78) and 2-year (86.16% vs 55.00%, p = 0.10) mortality were similar. On multivariable analysis, the need for a RVAD was associated with an increased hazard of 1-year (5.60 [1.96 to 16.01], p <0.01) and 2-year (5.17 [2.01 to 13.28], p <0.01) mortality. In conclusion, our series from a nontransplant center suggests that patients who survive the implant have acceptable short-term survival, even if they do not have a transplant option; thus, carefully selected patients with biventricular failure may benefit from an LVAD implant, even if an RVAD is needed.
尽管左心室辅助装置 (LVAD) 植入可提高晚期心力衰竭患者的生存率,但需要右心室辅助装置 (RVAD) 植入的严重右心室衰竭与短期发病率和死亡率增加相关。不适合移植的患者选择有限,这可能会影响非移植中心的决策和结果。我们对我们的非移植中心的所有 LVAD 植入进行了回顾性研究。主要分层标准是术后是否需要 RVAD 植入。主要结局是生存。使用 Cox 比例风险回归模型进一步评估死亡率。2017 年至 2022 年,128 例患者接受了初次 LVAD 植入,其中 24 例(18.75%)需要围手术期 RVAD 放置。RVAD 植入与手术死亡率增加相关(1.92% vs. 33.33%,p<0.01),1 年(91.29% vs. 60.60%,p<0.01)和 2 年生存率(84.05% vs. 36.36%,p<0.01)降低。然而,在存活至出院的患者中,1 年(93.00% vs. 91.67%,p=0.78)和 2 年(86.16% vs. 55.00%,p=0.10)死亡率相似。多变量分析显示,需要 RVAD 与 1 年(5.60[1.96 至 16.01],p<0.01)和 2 年(5.17[2.01 至 13.28],p<0.01)死亡率增加相关。结论,我们的非移植中心系列研究表明,即使没有移植选择,存活至植入的患者也有可接受的短期生存率;因此,即使需要 RVAD,仔细选择的双心室衰竭患者可能会从 LVAD 植入中获益。
