RESUMO
BACKGROUND: Prior studies have reported decreased use of an invasive approach for acute myocardial infarction (AMI) in patients undergoing transcatheter aortic valve replacement (TAVR). OBJECTIVES: The aim of this study was to determine whether prior TAVR affects the use of subsequent coronary revascularization and outcomes of AMI in a contemporary national data set. METHODS: Consecutive TAVR patients from 2016 to 2022 were identified from the U.S. Vizient Clinical Data Base who were hospitalized after the index TAVR hospitalization with ST-segment elevation myocardial infarction (STEMI) or non-ST-segment elevation myocardial infarction (NSTEMI). Patients with STEMI or NSTEMI with or without prior TAVR from the same time period were compared for the use of coronary angiography, revascularization, and in-hospital outcomes. Propensity score matching was used to account for imbalances in patient characteristics. RESULTS: Among 206,229 patients who underwent TAVR, the incidence of STEMI was 25 events per 100,000 person-years of follow-up, and that of NSTEMI was 229 events per 100,000 person-years. After propensity matching, the use of coronary revascularization was similar in the prior TAVR and no TAVR cohorts in both the STEMI (65.3% vs 63.9%; P = 0.81) and NSTEMI (41.4% vs 41.7%; P = 0.88) subgroups. Compared with patients without prior TAVR, in-hospital mortality was higher in the prior TAVR cohort in patients with STEMI (27.1% vs 16.7%; P = 0.03) and lower in those with NSTEMI (5.8% vs 8.2%; P = 0.02). CONCLUSIONS: In this large, national retrospective study, AMI events after TAVR were infrequent. There were no differences in the use of coronary revascularization for STEMI or NSTEMI in TAVR patients compared with the non-TAVR population. In-hospital mortality for STEMI is higher in TAVR patients compared with those without prior TAVR.

BACKGROUND: Minimalist approaches to Transcatheter aortic valve replacement (TAVR) have allowed for improved efficiency in care of patients. We hypothesized that improved efficiencies in care process may have led to increased adoption of a one night length of stay (LOS) in this patient group. OBJECTIVES: The authors aimed to study temporal trends in short length of stay following TAVR. METHODS: This is a nationwide temporal trends study using the 2016-2019 National In Patient Sample (NIS) registry. Short stay was defined as LOS of one night or less. Trends in proportion of patients with short stay were obtained. A multivariate model to identify predictors of short stay was built after adjusting for confounders. Secondary analysis of temporal trends was stratified by presence or absence of major complications (major bleeding requiring transfusion or pacemaker implantation [PPMI]). RESULTS: A total of 217,110 patients were included in the weighted sample. The proportion of patients with short stay significantly increased for those with and without complications (Ptrend < 0.001). The morbidity burden, as defined by the proportion of patients with a Charlson comorbidity index (CCI) score of ≥2 and rate of major complications decreased significantly. On multivariate analysis short stay was predicted by male sex, white ethnicity, Southern/Western regions and lower CCI score. Patients with major bleeding requiring transfusion or PPMI were less likely to have short stay (aOR 0.23 and aOR 0.12, p < 0.001 respectively). CONCLUSION: There is a national trend towards shorter LOS following TAVR. There is a decrease in major post procedural complication rates from 2016 to 2019.
