Abstract
Objectives: The aim of this study was to report the 1-year results of transcatheter aortic valve replacement (TAVR) with the Edwards SAPIEN 3 (S3) valve in extremely large annuli. Background: Favorable 30-day outcomes of S3 TAVR in annuli >683 mm2 have previously been reported. Pacemaker implantation rates were acceptable, and a larger left ventricular outflow tract and more eccentric annular anatomy were associated with increasing paravalvular leak. Methods: From December 2013 to December 2018, 105 patients across 15 centers with mean area 721.3 ± 36.1 mm2 (range 683.5 to 852.0 mm2) underwent TAVR using an S3 device. Clinical, anatomic, and procedural characteristics were analyzed. One-year survival and echocardiographic follow-up were reached in 94.3% and 82.1% of patients, respectively. Valve Academic Research Consortium-2 30-day and 1-year outcomes were reported. Results: The mean age was 76.9 ± 10.4 years, and Society of Thoracic Surgeons predicted risk score averaged 5.2 ± 3.4%. One-year overall mortality and stroke rates were 18.2% and 2.4%, respectively. Quality-of-life index improved from baseline to 30 days and at 1 year (p < 0.001 for both). Mild paravalvular aortic regurgitation occurred in 21.7% of patients, while moderate or greater paravalvular aortic regurgitation occurred in 4.3%. Mild and moderate or severe transvalvular aortic regurgitation occurred in 11.6% and 0%, respectively. Valve gradients remained stable at 1 year. Conclusions: S3 TAVR in annular areas >683 mm2 is feasible, with favorable mid-term outcomes.
