数据说明

Background: There is a paucity of data regarding the comparative safety and effectiveness of transcatheter aortic valve replacement (TAVR) versus surgical aortic valve replacement (SAVR) in patients with prior myocardial infarction (MI).
Methods: We queried the NIS database (2012–2016) to identify patients with a prior history of MI who underwent isolated AVR. We conducted a propensity matching analysis comparing patients with TAVR versus SAVR based on patient demographics, comorbidities and hospital characteristics. The primary outcome was in-hospital mortality.
Results: Among 24,090 hospitalizations with prior MI undergoing isolated AVR, 58.5% underwent TAVR. Over the study period, there was an increase in the proportion of patients undergoing TAVR and a decrease in patients undergoing SAVR (PtrendConclusion: In this nationwide observational study, there has been a steady increase in the number of TAVRs performed in patients with prior MI. Compared with SAVR, TAVR was associated with similar in-hospital mortality and a lower rate of complications and length of stay.
