B-49 | Impact of Insurance Status on Outcomes Following MitraClip for Severe Mitral Regurgitation: A National Inpatient Sample Analysis

were stratified into two groups based on solid organ transplants.Multivariate logistic regression and propensity score matching (PSM) were performed to assess outcomes.Results: Of the 39,867 patients who underwent TEER, 0.9% (n360) had SOT.SOT patients were younger (66 vs. 77 years), had longer lengths of stay (5.61 vs. 4.7 days), higher comorbidity scores (2.55 vs. 2.47), and greater resource utilization ($247,057 vs. $228,678 compared to non-SOT patients.SOT patients were more likely to be insured through Medicaid or private insurance.On multivariate analysis, SOTstatus was associated with higher odds of mortality (aOR 4.7, 95% CI 2.4-9.3;p<0.001), sudden cardiac arrest (aOR 2.3, 95% CI 1.3-4.1;p<0.001), postop syncope (aOR 10.0, 95% CI 5.9-16.9;p<0.001).Before PSM, SOT patients had significantly higher rates of mortality (5.6% vs. 2.01%), sudden cardiac arrest (8.5% vs. 3.7%), and MACCE (11.3% vs. 3.7%; p<0.001), total bleeding (9.9% vs 5.36%) and post-op syncope (4.1% vs 0.29%; p<0.001).Conclusions: SOT in TEER patients is associated with higher odds of mortality, sudden cardiac arrest, bleeding, and postoperative syncope.SOT patients are younger, experience longer hospital stays.
