Abstract
BACKGROUND: Asian patients have smaller aortic annuli. Although 20-mm balloon-expandable (BE) transcatheter heart valves (THV) are manufactured for transcatheter aortic valve implantation (TAVI) in these cases, the supra-annular design of self-expandable (SE) THV is considered more suitable; however, real-world comparative data are scarce. METHODS AND RESULTS: ) was significantly less with SE-THV than with BE-THV (8% vs. 55%; P=0.04). Hemodynamic findings were consistent up to 1 year. CONCLUSIONS: Small annuli are often seen in Asian patients, for whom SE-THV implantation results in favorable hemodynamics with less PPM.
