ABSTRACT
The prevalence of coronary artery disease (CAD) varies between 40" and 75" in patents with aortic stenosis (AS) and increases with age. In patients with severe AS, CAD increases risks associated with surgical aortic valve replacement (SAVR). Significant CAD may be related to a higher risk of ischaemia associated with trans-catheter aortic valve implantation (TAVI). During TAVI, rapid pacing is performed at the time of balloon inflation and valve deployment. In patients undergoing TAVI, using a physiological scoring system to define the severity of CAD may be clinically useful and aid decision-making. This would define the complexity and extent of CAD and would also take into account the area of myocardium at risk. Data are available only in a high-risk population cohort and is limited to observational studies and registries. No meaningful data are available in the intermediate or low-risk cohort.
