Outcome of Patients With Severe Aortic Stenosis and Normal Coronary Arteries Undergoing Transcatheter Aortic Valve Implantation

Coronary artery disease and severe aortic stenosis (AS) often coexist. This study sought to investigate the impact of normal coronary arteries as negative risk marker in patients undergoing transcatheter valve implantation (TAVI). Consecutive with AS TAVI were dichotomized according presence or absence arteries, defined lesions diameter ≥30% vessels ≥1.5 mm on angiogram without prior revascularization. The primary end point was 1-year mortality. Out 987 TAVI, 258 (26%) had arteries. These younger, more likely women, lower EuroSCORE II STS scores. Although mortality at 30 days similar atherosclerosis groups (3.1% vs 5.6%, p = 0.11), it those 1 year (8.9% 17%, p = 0.003). In multivariable analysis, independently predicted (adjusted HR 0.57, 95% CI 0.37 0.90, p = 0.02). conclusion, this TAVI.
