Highlights of the COMPARE-TAVI 1 Substudy

Among the key takeaways from the analysis of the COMPARE-TAVI 1 trial are the following:

1. A distinct phenotype of severe aortic stenosis (AS) exists, characterized by a normal stroke volume index (SVi ≥35 mL/m2) despite a reduced left ventricular ejection fraction (LVEF <50%), occurring in approximately 10.7% of patients undergoing transcatheter aortic valve implantation (TAVI).
