Short-and mid-term outcomes in patients deemed inoperable undergoing transapical and transfemoral tavr with an sts-prom below four percent

Abstract

Transapical (TA) TAVR is known to be associated with increased mortality and vascular complications compared with transfemoral (TF) TAVR in high-risk and inoperable patients. However, safe alternative access methods remain crucial. We aimed to (1) evaluate the 30-day and 1-year outcomes comparing TA and TF TAVR in patients with an STS-PROM of <4% deemed inoperable and (2) determine dependent and independent predictors for all-cause one-year mortality. Data were collected from a single-center registry consisting of 340 eligible patients. One-to-one propensity score matching was performed (n = 50 TA, n = 50 TF). Primary endpoints were all-cause mortality, stroke, and major bleeding. Predictors for all-cause one-year mortality were evaluated. Thirty-day mortality (TF vs. TA: 0.0% vs. 4.0%; p = 0.153) was comparable in both cohorts. One-year all-cause mortality was twice as high in TA patients (TF vs. TA: 10.0% vs. 20.0%, p logrank = 0.165, HR 2.10). Cerebrovascular events and major bleeding during one-year follow-up were similar. The multivariate analysis identified hemoglobin <12 g/dL at admission and dual antiplatelet therapy as strong predictors for one-year mortality. Although femoral access is the primary access with favorable 30-day and 1-year results, transapical access was successful for patients unsuitable for TF TAVR, showing acceptable short-and mid-term results in inoperable patients with low-risk profiles.
