Twelve-month healthcare utilization and expenditures in Medicare fee-for-service patients with clinically significant mitral regurgitation.

Aim: This study sought to quantify the healthcare burden of Medicare patients with clinically significant mitral regurgitation (sMR). Materials & methods: Proxy definitions were used for sMR, including MR surgery, atrial fibrillation, pulmonary hypertension or >2 echocardiograms. Results: In this study, 11,173 patients had significant degenerative MR (sDMR); 25,402 had significant functional MR (sFMR); and 12,232 had significant uncharacterized MR (sUMR). Patients with sFMR (18,880) were more likely to be hospitalized and present to the emergency department compared with patients with sDMR (9,795) or sUMR (10,587). Annual healthcare expenditures for sMR patients were: US$29,328 for sFMR; US$17,112 for sUMR; and US$12,870 for sDMR. Conclusion: Novel therapeutic interventions merit further evaluation to reduce the substantial healthcare burden of sMR in the Medicare population.
