摘　　要：To the Editor:Approximately 2%of people>65 years old have aortic stenosis(AS).[1]Without intervention,AS is a rapidly progressive valvular heart disease with a 2-year mortality of 50%.[1]Since the first transcatheter aortic valve replacement(TAVR)was performed by Cribier et al[2]in 2002,TAVR has been suggested to be non-inferior in AS patients of various risk stratifications.Post-TAVR complications are essential in predicting patient survival and improving quality of life,especially with the procedure being performed in an increasing population of low-risk patients.[3]Among them,myocardial infarction(MI)is a rare but life-threatening complication usually caused by the obstruction of coronary ostia.[1]In comparison,peri-procedural myocardial injury,primarily characterized by the elevation of cardiac markers,is a relatively common complication of TAVR.Although recent studies have demonstrated promising results of cardiac markers in predicting cardiovascular adverse events,the impact of peri-procedural myocardial injury on short-term and long-term mortality has yet to be established.
