Multicenter StudyPrognostic significance of aortic valve gradient in patients with severe aortic stenosis undergoing transcatheter aortic valve replacement.
To evaluate the effect of baseline aortic valve gradient (AVG) both as a continuous and a categorical variable on mortality in patients undergoing transcatheter aortic valve replacement (TAVR), focusing on the high-gradient severe aortic stenosis (AS) patients. ⋯ Baseline AVGs show an inverse association with mortality post-TAVR. These results were consistent also in patients with high-gradient AS, suggesting that AVG can be used to identify patients most likely to benefit from TAVR.

Multicenter StudyProcedural and 30-day clinical outcomes following transcatheter aortic valve replacement with lotus valve: Results of the RELEVANT study.
We report procedural and 30-day clinical outcomes following transcatheter aortic valve replacement (TAVR) with Lotus Valve system in a high-risk population. ⋯ RELEVANT study showed that TAVR using Lotus, in a real-world population of patients with severe aortic stenosis at high surgical risk, was associated with excellent device success implantation and early safety according to VARC-2 definition. The pacemaker implantation rate was about a third of patients. © 2017 Wiley Periodicals, Inc.
