D-39 | Inpatient Outcomes of Mitral Valve Transcatheter Edge-to-Edge Repair (TEER) in Patients With Acute Decompensated Heart Failure

TEER is a favorable alternative to surgery in patients with heart failure (HF) and mitral regurgitation (MR), but its effect acute decompensated (ADHF) not well studied. We aim study the short-term outcomes of these using largest US inpatient database. queried 2016-2019 NIS database ICD-10 codes identify all adult MR ADHF. Outcomes who underwent during index hospitalization were compared those did not. Multivariate logistic regression was used compare rates cardiogenic shock, mechanical ventilation, use circulatory support (MCS), cardiac transplant, kidney injury (AKI) need dialysis; linear length stay (LOS). Of 1,854,806 ADHF, 24,905 (1.36%) TEER. Overall mortality 3.39% significantly lower recipients [aOR 0.39 (0.30-0.49), p<0.01]. LOS shorter group (4 vs 5.9 days). had ventilation 0.81 (0.70-0.94), p=0.01] AKI 0.43 (0.39-0.47), p<0.01], although requiring dialysis comparable. higher shock. Rates MCS comparable except intraaortic balloon pump placement, which more frequent group. ADHF associated LOS. Prospective trials are needed establish as feasible intervention
