Contemporary outcomes of surgical aortic valve replacement in patients referred for a transcatheter approach.

The purpose of this study is to examine which patients referred to our structural valve clinic for potential transcatheter aortic valve replacement (TAVR) are receiving surgical aortic valve replacement (SAVR) whether due to unsuitable anatomy for TAVR versus other reasons. Individuals referred for TAVR from January 2019 to March 2022, who ultimately underwent SAVR were examined, retrospectively. Patients were divided into 2 surgical groups: TAVR was technically unsuitable (SAVR-TU) and those in which TAVR was technically feasible (SAVR-TF). 215 patients referred for TAVR underwent SAVR with 61 (28.4%) patients in the SAVR-TU group and 154 (71.6%) in the SAVR-TF group. The SAVR-TU group were more commonly female (52.5% vs 23.4%, p < 0.0001), had a higher incidence of stroke at baseline (9.8% vs 2.0%, p = 0.017) were frailer (5-m gait 5.2 s vs 4.7 s, p = 0.0035), and had a higher Society of Thoracic Surgery risk score (2.2 vs 1.7, p = 0.04). In the SAVR-TU group, unsuitability for TAVR was due to inadequate aortic root anatomy (86.9%), and poor peripheral access (6.6%). In the SAVR-TF group, the most common reasons for SAVR referral were concomitant coronary artery disease (42.9%), bicuspid aortic valve disease (16.9%), and concomitant aortic aneurysm (10.4%). Overall, in-hospital mortality was 1.4% with no difference between both groups. One-year survival was 96.7%. Despite a higher trend of aortic stenosis being treated with TAVR, higher risk patients unsuitable for TAVR can have SAVR with excellent outcomes. Moreover, patients with AS and concomitant other pathology should be evaluated for cardiac surgery.
