Coronary artery disease (CAD) is the leading cause of mortality among aortic stenosis  (AS) patient populations due to common pathogenetic factors such as ageing, atherosclerotic plaques, multi-morbid risks including diabetes, hypertension and dyslipidaemia, or procedural related coronary access obstruction, with the revolution of transcatheter aortic valve implantation  (TAVI).
