Transcatheter Aortic Valve Replacement in Patients With Small Aortic Annulus: An Observational Study.

ABSTRACT:

Background

The Small Annuli Randomized to Evolut or SAPIEN Trial showed superior hemodynamics of self-expanding valves (SEVs) over balloon-expandable valves (BEVs) in patients with small aortic annuli (SAA). The long-term clinical implications of these hemodynamic differences are unknown.

Methods

We conducted an observational cohort study of patients with SAA, defined as an aortic valve annular area ≤430 mm² on cardiac computed tomography, who underwent transcatheter aortic valve replacement using BEV or SEV at a single institution between August 2013 and February 2021. Patients undergoing valve-in-valve procedures or alternative access were excluded. Patient-prosthesis mismatch (PPM) was defined as moderate when indexed effective orifice area of 0.65-0.85 cm
