A revised methodology for aortic-valvar complex calcium quantification for transcatheter aortic valve implantation

Structured PICO

Does aortic-valvar complex calcium quantification using CT scans predict paravalvular leak in patients undergoing TAVI?

Population

Patients undergoing transcatheter aortic valve implantation (TAVI)

Intervention

Aortic-valvar complex calcium quantification using non-contrast or contrast CT scans

Outcome

Paravalvular leak (PVL)surrogate

Leaflet and LVOT calcium quantification via CT (contrast or non-contrast) is a significant predictor of paravalvular leak in TAVI.

Abstract

Both leaflet and LVOT calcium are significant predictors of PVL and exert an important synergistic influence on this complication, even in appropriately sized valves. With careful attention to thresholds for detection, clinically relevant leaflet calcium volumes can be identified with either non-contrast or contrast CT scans.
