Rapid-Deployment Aortic Valve Replacement after Previous Mechanical Valve Implantation

摘要

Recent studies report a reproducible reduction of myocardial ischemic and cardiopulmonary bypass times along with excellent hemodynamics and low rates of paravalvular leakage for rapid-deployment valves. A 68-year-old female patient with aortic stenosis and a mechanical mitral valve which was implanted in 2006 received rapid-deployment aortic valve replacement. The procedure could be performed with a cross-clamp time of 45 minutes and a cardiopulmonary bypass time of 60 minutes. Postoperative course was uncomplicated and the patient was discharged to the referring hospital on postoperative day 8.
