Longitudinal Hemodynamics of Transcatheter and Surgical Aortic Valves in the PARTNER Trial.

ABSTRACT:

Importance

Use of transcatheter aortic valve replacement (TAVR) for severe aortic stenosis is growing rapidly. However, to our knowledge, the durability of these prostheses is incompletely defined.

Objective

To determine the midterm hemodynamic performance of balloon-expandable transcatheter heart valves.

Design, setting, and participants

In this study, we analyzed core laboratory-generated data from echocardiograms of all patients enrolled in the Placement of Aortic Transcatheter Valves (PARTNER) 1 Trial with successful TAVR or surgical AVR (SAVR) obtained preimplantation and at 7 days, 1 and 6 months, and 1, 2, 3, 4, and 5 years postimplantation. Patients from continued access observational studies were included for comparison.

Interventions
