Objectives: The aim of this study was to determine factors affecting paravalvular leak (PVL) in transcatheter aortic valve replacement (TAVR) with the Edwards SAPIEN 3 (S3) valve in extremely large annuli. Background: The largest recommended annular area for the 29-mm S3 is 683 mm2. However, experience with S3 TAVR in annuli >683 mm2 has not been widely reported. Methods: From December 2013 to July 2017, 74 patients across 16 centers with mean area 721 ± 38 mm2 (range: 684 to 852 mm2) underwent S3 TAVR. The transfemoral approach was used in 95%, and 39% were under conscious sedation. Patient, anatomic, and procedural characteristics were retrospectively analyzed. Valve Academic Research Consortium–2 outcomes were reported. Results: Procedural success was 100%, with 2 deaths, 1 stroke, and 2 major vascular complications at 30 days. Post-dilatation occurred in 32%, with final balloon overfilling (1 to 5 ml extra) in 70% of patients. Implantation depth averaged 22.3 ± 12.4% at the noncoronary cusp and 20.7 ± 9.9% at the left coronary cusp. New left bundle branch block occurred in 17%, and 6.3% required new permanent pacemakers. Thirty-day echocardiography showed mild PVL in 22.3%, 6.9% moderate, and none severe. There was no annular rupture or coronary obstruction. Mild or greater PVL was associated with larger maximum annular and left ventricular outflow tract (LVOT) diameters, larger LVOT area and perimeter, LVOT area greater than annular area, and higher annular eccentricity. Conclusions: TAVR with the 29-mm S3 valve beyond the recommended range by overexpansion is safe, with acceptable PVL and pacemaker rates. Larger LVOTs and more eccentric annuli were associated with more PVL. Longer term follow-up will be needed to determine durability of S3 TAVR in this population.
