Abstract

In this cohort analysis of Medicare beneficiaries, use of mechanical aortic valves was associated with a higher risk for death on the date of surgery and within the 30 days after surgery compared with bioprosthetic aortic valves among patients who underwent concurrent AVR and coronary artery bypass graft but not isolated AVR.
