RESUMEN
AIM: We sought to determine the racial and ethnical disparities in the delivery of TAVR and to evaluate the in-hospital outcomes and utilization of TAVR stratified by patient ethnicity. METHOD: Using a national inpatient sample database between 2011 and 2015, we identified all adult patients who had TAVR. Races were identified and white race was set as control. Multiple logistic regression analysis was performed for the primary outcome of in-hospital mortality. RESULTS: Out of 58â174 patients who underwent TAVR, 50â809 (87.3%) were white, 2327 (4.0%) were black, 2311 (4.0%) were Hispanic, 640 (1.1%) Asian, 105 (0.2%) Native American and 1982 (3.4%) of other ethnicities. We found a statistically significant linear uptrend in the utilization of TAVR in patients of all races between the years 2011 and 2015. White, black, Hispanic and Native American patients had a downward linear trend for mortality during the studied years (Pâ≤â0.005 for all). Black patients had lower in-hospital mortality [2.8 vs. 3.6%, odds ratio (OR)â=â0.62; 95% confidence interval (CI) 0.44, 0.81 Pâ<â0.001] compared with white patients, whereas Hispanic patients and Native Americans had higher in-hospital mortality compared with white patients (4.5% OR 1.26; 95% CI 1.01, 1.56 Pâ=â0.041), (9.5% OR 4.44; 95% CI 2.25, 8.77 Pâ<â0.001), respectively. CONCLUSION: Overall, TAVR utilization is associated with lower mortality. There is a rising trend in utilization of TAVR in the black population with a significantly favorable mortality trend compared with the white population.

BACKGROUND: The utilization of mechanical circulatory support (MCS) for percutaneous coronary intervention (PCI) using percutaneous ventricular assist device (PVAD) or intra-aortic balloon pump (IABP) has been increasing. We sought to evaluate the outcome of coronary intervention using PVAD compared with IABP in noncardiogenic shock and nonacute myocardial infarction patients. METHOD: Using the National Inpatient Sampling (NIS) database from 2005 to 2014, we identified patients who underwent PCI using ICD 9 codes. Patients with cardiogenic shock, acute coronary syndrome, or acute myocardial infarction were excluded. Patient was stratified based on the MCS used, either to PVAD or IABP. Univariate and multivariate logistic regression were performed to study PCI outcome using PVAD compared with IABP. RESULTS: Out of 21,848 patients who underwent PCI requiring MCS, 17,270 (79.0%) patients received IABP and 4,578 (21%) patients received PVAD. PVAD patients were older (69 vs. 67, p < .001), were less likely to be women (23.3% vs. 33.3%, p < .001), and had higher rates of hypertension, diabetes, hyperlipidemia prior PCI, prior coronary artery bypass graft surgery, anemia, chronic lung disease, liver disease, renal failure, and peripheral vascular disease compared with IABP group (p ≤ .007). Using Multivariate logistic regression, PVAD patients had lower in-hospital mortality (6.1% vs. 8.8%, adjusted odds ratio [aOR] 0.62; 95% CI 0.51, 0.77, p < .001), vascular complications (4.3% vs. 7.5%, aOR 0.78; 95% CI 0.62, 0.99, p = .046), cardiac complications (5.6% vs. 14.5%, aOR 0.29; 95% CI 0.24, 0.36, p < .001), and respiratory complications (3.8% vs. 9.8%, aOR 0.37; 95% CI 0.28, 0.48, p < .001) compared with patients who received IABP. CONCLUSION: Despite higher comorbidities, nonemergent PCI procedures using PVAD were associated with lower mortality compared with IABP.
