Objectives: This study sought to evaluate SAPIEN 3 (S3) (Edwards Lifesciences, Irvine, California) positioning using different strategies. Background: Aortic valve-in-valve (ViV) is associated with high risk of elevated gradients. Methods: S3 aortic ViV procedures in stented bioprostheses were studied. Transcatheter heart valve (THV) positioning was analyzed in a centralized core lab blinded to clinical outcomes. A combined endpoint of severely elevated mean gradient (≥30 mm Hg) or pacemaker need was established. Two positioning strategies were compared: central marker method and top of S3 method. Optimal final depth was defined as S3 depth ≤20%. Results: A total of 113 patients met inclusion criteria and were analyzed (76.5 ± 9.7 years of age, 65.8% male, STS score 8 ± 7.6%). THVs had incomplete shortening in comparison to fully expanded valves (92 ± 3.4%), and expansion was more complete in optimal positioning cases compared with others (93.2 ± 2.7% vs. 91.5 ± 3.5%; p = 0.027). The central marker method demonstrated greater correlation with final implantation depth than the top of S3 method (R2 of 0.48 and 0.14; p < 0.001 and p = 0.001, respectively). The combined endpoint rate was 4.3% in the optimal (higher than 3 mm) implantation group, 12% in the intermediate group, and 50% in the low group (p < 0.001). There were no cases of THV embolization. In cases with central marker higher than 3 mm, 72.4% had optimal final depth. In those with central marker higher than 6 mm, 90% had optimal final depth. Conclusions: Optimal S3 positioning in aortic ViV is associated with better outcomes. Central marker positioning is more reliable than top of S3 positioning. Central marker bottom position should be 3 mm to 6 mm above the ring.
