Self-expanding vs. balloon-expandable transcatheter heart valves in small aortic annuli.

ABSTRACT:

Background

Clinical consequences of prosthesis-patient mismatch (PPM) after transcatheter aortic valve replacement (TAVR) is currently in the focus of clinical research. Patients with small aortic annulus are at higher risk to display PPM. Data on incidence and clinical consequences of PPM after TAVR with either balloon-expandable (BEV) or self-expanding (SEV) transcatheter heart valves in small aortic annulus are sparse.

Methods

Patients with small aortic annulus (perimeter < 72 mm or aortic annulus area < 400 mm²) who underwent BEV or SEV with contemporary transcatheter heart valve types were identified from the institutional TAVR database. Propensity score matching was applied for imbalanced baseline characteristics between patients undergoing BEV or SEV. Echoc
