| Aortic stenosis is a valvular heart disease (VHD) mainly caused by rheumatic fever sequelae, congenital aortic valve structural abnormalities, senile aortic valve calcification, and so on, among which calcific aortic stenosis is the chief form of aortic stenosis. Echocardiography is often used technique to evaluate and diagnose aortic stenosis in the world, the normal adults aortic valve area (AVA)≥ 3.0 cm2, when AVA decreases to 1/3 or more of the normal, the aortic valve forward flow will be blocked, most mild to moderate and some severe aortic stenosis patients have no clinical symptoms during daily activities. The epidemiology of aortic stenosis varies greatly in different regions, ages, genders, and races. Aortic stenosis increases the risk of perioperative cardiovascular complications in non cardiac surgery, the risk depends on VHD severity and non cardiac surgery type, the perioperative mortality of untreated severe aortic stenosis patients undergoing non cardiac surgery is high. This review describes the recent progress in the diagnosis, classification, pathological mechanism, treatment and perioperative anesthesia management of aortic stenosis undergoing non-cardiac surgery． |
