The VARC II time-related valve safety composite was defined as the rate of valve-related dysfunction (mean aortic valve gradient ≥ 20 mm Hg, EOA ≤ 0.9-1.1 cm2 depending on body surface area and/or DVI \<0.35, AND/ OR moderate or severe prosthetic valve regurgitation), aortic valve reintervention, prosthetic valve endocarditis, prosthetic valve thrombosis, thromboembolic events, and VARC II bleeding events.

The Evolut™ R system provides operators with the ability to resheath or recapture the valve before it is completely deployed in the event of initial suboptimal positioning. Successful resheath was defined as successfully retrieving a portion of the valve into the capsule of the delivery catheter, and successful recapture was defined as successfully recapturing the entirety of the valve into the capsule of the delivery catheter.
