Does aortic-valvar complex calcium quantification using CT scans predict paravalvular leak in patients undergoing TAVI?
Does aortic-valvar complex calcium quantification using CT scans predict paravalvular leak in patients undergoing TAVI?
Leaflet and LVOT calcium quantification via CT (contrast or non-contrast) is a significant predictor of paravalvular leak in TAVI.
Answers are grounded in this paper and cite their sources.
CT calcium quantification may aid PVL risk stratification in TAVI; leaves open prospective validation of clinical impact.
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.
