The utilization of transcatheter aortic valve replacement (TAVR) has grown exponentially over the years with volumes now exceeding that of surgical aortic valve replacement (SAVR) and indications gradually expanding from patients with prohibitive operative risk to patients at low operative risk . It is, therefore, increasingly important to interpret the significance of periprocedural TAVR complications. While myocardial infarction is a rare (~1%) but serious complication typically related to coronary ostia occlusion following valve placement , periprocedural myocardial injury (PPMI) occurs in a majority of patients undergoing TAVR. PPMI rates have, in fact, ranged from 17% to 95% of TAVR patients ( Table 1 ), depending on the definition used in the study . The extent of myocardial injury post-SAVR is related to myocardial infarction and death , while the significance of myocardial injury post-TAVR remains the subject of investigation.
