Mitral transcatheter edge-to-edge repair (TEER) in patients with rheumatic heart disease (RHD) is challenging owing to leaflet thickening and calcification but is performed in select cases. Limited data exist on its outcomes. The aim of this analysis was to investigate the safety and efficacy of mitral TEER in patients with severe symptomatic rheumatic mitral regurgitation. We queried the Nationwide Readmissions Database for hospitalizations for mitral TEER between 2016 and 2018. Propensity score-weighted regression analysis was conducted to evaluate the association of RHD with in-hospital outcomes and 90-day readmissions after mitral TEER. A total of 18,240 procedures were included in the analysis, including 1,779 in patients with RHD. Mitral TEER in patients with RHD was associated with similar in-hospital mortality to that in patients without RHD (odds ratio [OR] 1.47, 95% confidence interval [CI] 0.94 to 2.30, p = 0.089). However, RHD was associated with higher acute myocardial infarction (OR 1.65, 95% CI 1.07 to 2.56), acute kidney injury (OR 1.58, 95% CI 1.30 to 1.94), ventricular arrhythmia (OR 1.50, 95% CI 1.12 to 2.01), high-degree heart block (OR 1.67, 95% CI 1.25 to 2.23), and conversion to open surgical repair/replacement (OR 2.53, 95% CI 1.02 to 6.30). Mitral TEER in RHD was also associated with higher 90-day all-cause readmission (hazard ratio [HR] 1.19, 95% CI 1.04 to 1.47, p = 0.012). In conclusion, mitral TEER in patients with RHD is associated with higher rates of hospital complications, crossover to surgery, and readmissions but could be performed selectively in patients at high surgical risk who have favorable anatomy.
