Surgical Treatment Of Native Double Valve Endocarditis

Objective：There are little data concerning surgical treatment andlong-term outcome in patients with native double valve endocarditis. Theaim of this study was to report the long-term results in patients withnative double valve endocarditis who received double valve surgeryduring acute phase.Method:From1998to2012a total of32patients (mean age,44±8years;78%male patients) with native double valve endocarditis underwentdouble valve replacement during acute phase. In-hospital morbidity andmortality, long-term survival and freedom from recurrent endocarditiswere analyzed.Result:There were3(9%) in-hospital deaths. Patients with the followingfeatures had a higher rate of operative mortality: preoperative serumcreatinine>2mg/dl, ejection fraction less than40%and urgent surgery.The3-,5-,8-year survival was87%±6%,81%±8%,69%±11%,respectively. And freedom from recurrent endocarditis was96%±4%at3years,80%±11%at8years.Conclusion:Surgical treatment of native double valve endocarditis duringacute phase is feasible with acceptable operative mortality, and thelong-term survival and freedom from recurrent endocarditis are alsogood.
