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.

Comparative Study Observational StudyHospital teaching status and trascatheter aortic valve replacement outcomes in the United States: Analysis of the national inpatient sample.
Evidence suggests that medical service offerings vary by hospital teaching status. However, little is known about how these translate to patient outcomes. We therefore sought to evaluate this gap in knowledge in patients undergoing Transcatheter aortic valve replacement (TAVR) in the United States. ⋯ Most TAVR related short-term outcomes including all cause in-hospital mortality are about the same in teaching and nonteaching hospitals. However, AKI, length of hospital stay and TAVR related cost were significantly higher in teaching than nonteaching hospitals. There was more use of mechanical circulatory support in nonteaching than teaching hospitals.
