Long-term outcomes of measured and predicted prosthesis-patient mismatch following transcatheter aortic valve replacement.

ABSTRACT:

Background

Both measured and predicted effective orifice area (EOA) indexed to the body surface area (EOAi) have been suggested to define prosthesis-patient mismatch (PPM) in patients undergoing transcatheter aortic valve replacement (TAVR). The impact of PPM on clinical outcomes may accumulate with extended follow-up and vary according to the definition used.

Aims

We aimed to investigate the long-term clinical impact of PPM in patients undergoing TAVR.

Methods

Patients in a prospective TAVR registry were stratified by the presence of moderate (0.65-0.85 or 0.55-0.70 cm²/m² if obese) or severe (≤0.65 or ≤0.55 cm²/m² if obese) PPM according to echocardiographically measured EOAi (measured PPM), predicted EOAi based on publish
