Abstract

Abstract: Background: Left ventricular assist device (LVAD) implantation is frequently employed in patients with end‐stage heart failure. The outcomes of addressing the repair of all substantial aortic valvular disease at the time of LVAD implantation remain unclear. We sought to assess the clinical outcomes in patients undergoing LVAD implantation concomitant with aortic valve procedures (AVPs) compared with isolated LVAD implantation. Methods: A literature search was performed using PubMed, Embase, and Cochrane library from inception till June 2022. Primary outcomes included short‐term mortality and long‐term survival. Random effects models were used to compute mean differences and odds ratios with 95% confidence intervals (CIs). Results: A total of 14 observational studies ( N = 52 693) met our inclusion criteria. Concomitant LVAD implantation and AVPs were associated with higher short‐term mortality (OR = 1.61 [95% CI, 1.06–2.42]; p = 0.02) and mean CPBt (MD = 43.25 [95% CI, 22.95–63.56]; p < 0.0001), and reduced long‐term survival (OR = 0.70 [95% CI, 0.55–0.88]; p = 0.003) compared with isolated LVAD implantation. No difference in the odds of cerebrovascular accident (OR = 1.05 [95% CI, 0.79–1.39]; p = 0.74) and mean length of hospital stay (MD = 2.89 [95% CI, −4.04 to 9.82]; p = 0.41) was observed between the two groups. On adjusted analysis, short‐term mortality was significantly higher in the LVAD group with concurrent AVPs when compared with the isolated LVAD group (aHR = 1.50 [95% CI, 1.20–1.87]; p = 0.0004). Conclusions: Concurrent AVPs were associated with higher short‐term mortality and reduced long‐term survival in patients undergoing LVAD implantation compared with isolated LVAD implantation. Abstract : Concurrent aortic valve procedures (AVPs) significantly increase short‐term mortality and reduce long‐term survival in patients undergoing left ventricular assist device (LVAD) implantation as compared to isolated LVAD implantation. This implies that concurrent AVPs should be performed with caution as they have their implications and risks.
