About this study

Severe aortic stenosis (AS) is often accompanied by coronary artery disease (CAD). While coronary computed tomography angiography (CCTA) is routinely used before aortic valve replacement (AVR) to evaluate coronary anatomy, it lacks physiological assessment of myocardial ischemia. This prospective, single-center, randomized controlled trial aims to evaluate whether integrating functional assessment using CT-derived fractional flow reserve (CT-FFR) with CCTA can optimize revascularization decision-making and improve clinical outcomes. A total of 300 severe AS patients scheduled for transcatheter or surgical AVR will be randomly assigned to either the experimental group (revascularization decisions guided by both CCTA and CT-FFR) or the control group (decisions guided by CCTA alone). Participants will be followed up for 1 year to assess major adverse cardiovascular events and other clinical outcomes.
