 This study examined the effects of transcatheter aortic valve replacement, TAVR, on coronary blood flow in the left anterior descending LAD, left circumflex LCX, and right coronary arteries, RCA, using a computational model. The results showed that coronary blood flow in the LAD, LCX, and RCA varied depending on the patient. Additionally, valvular pressure gradient, left ventricle, LV, workload, and maximum LV pressure decreased by 61.5%, 4.5%, and 13% respectively, while men arterial pressure and cardiac output increased by 6.9% and 9.9%. This study provides valuable information regarding the effects of TAVR on coronary blood flow, which could potentially improve the accuracy of preoperative planning and postoperative monitoring.
