Abstract

Patients with left ventricular assist device (LVAD) often develop aortic insufficiency requiring an intervention on the aortic valve. We sought to analyze the outcomes of patients with a history of LVAD who underwent either transcatheter aortic valve replacement or surgical aortic valve replacement. The Nationwide Readmission Database was used to extract relevant patient information from January 1, 2016, to December 31, 2018. The Nationwide Readmission Database is a nationally representative sample of all-payer discharges from United States nonfederal hospitals. The primary outcome of interest was in-hospital mortality. Secondary outcomes included length of stay, clinical outcomes, costs, and 30-day all-cause readmissions. Complex samples multivariable logistic and linear regression models were used to determine the association of procedure type with outcomes. Among 148 hospitalizations with a history of LVAD, 87 underwent transcatheter aortic valve replacement (TAVR), and 61 underwent surgical aortic valve replacement (SAVR). The inpatient mortality in SAVR group was numerically higher compared to the TAVR cohort, however, it did not reach statistical significance. The use of invasive mechanical ventilation, and rates of cardiogenic shock, bleeding, and vascular complications were higher in the SAVR cohort compared to the TAVR cohort. The mean length of stay and costs were higher in the SAVR cohort compared to the TAVR cohort. The 30-day all-cause readmission rate was numerically higher in the SAVR group but not statistically significant. TAVR in patients with LVAD may be a viable treatment option for patients with AI with potential for better inpatient mortality and inpatient outcomes compared to patients who undergo SAVR in appropriately selected patients.
