Abstract 14339: Disparities in Transcatheter Mitral Valve Repair in Racial Minorities - From the National Inpatient Sample

Abstract

Introduction: Racial disparities in cardiovascular diseases and interventions have been widely reported in previous studies, Whether the racial disparities exist with transcatheter mitral valve repair (TMVr) is largely unknown. Hypothesis: The purpose of this study is to assess racial disparities in the utilization and outcome of TMVr procedure in the United States using the National Inpatient Sample (NIS) database. Methods: We analyzed NIS data from January 2013 to December 2017 using the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes and International Classification of Diseases, 10th Revision, Clinical Modification ICD-10-CM codes. Multivariable analysis was done by using logistic regression model to estimate adjusted odds ratios (aORs) with 95% confidence intervals (CIs) to determine variability in mortality, home discharges, vascular complications, cardiac complications, pulmonary complications, post op stroke and acute kidney injury by race. Results: A total of 13,410 weighted hospitalizations for TMVr procedure were included in our analysis. Multiple logistic regression analysis showed no significant difference in hospital mortality among the three racial groups. Pulmonary complications were more likely in the African American (adjusted Odds Ratio [aOR], 1.326[95% CI, 1.03-1.706], p-value= 0.03) and Hispanic population (aOR, 1.362[95% CI, 1.034-1.794], p-value= 0.03) (Figure). Conclusions: No significant difference in hospital mortality was noted among Caucasian, African American and Hispanic patients undergoing TMVr, however, we report a higher rate of post procedure respiratory complications in the minority races compared to Caucasian race.
