Abstract： Objective To summarize the methods and results of supra-annular aortic valve replacement（AVR） in patients with severely damaged aortic annulus. Methods Supra-annular AVR was performed in 5 patients between March 2008 and Dec. 2010 in Changhai Hospital, Second Military Medical University. There were 4 males and 1 female with their mean age of 46.3 years (ranging from 38 to 53 years). Non-specific infectious diseases were diagnosed in 4 patients who had severe paravalvular leakage after their first AVR operations (2 patients with Behcet’s disease and 2 patients with arteritis), and one patient had severe infectious endocarditis. All the patients had severely destroyed aortic annulus and could not undergo routine AVR. The prosthetic valves were fixed to the aortic sinus wall between the annulus and coronary arterial ostia, and the sutures passed through from the outside of aortic wall into the inside and prosthetic valve ring. Coronary artery bypass grafting was performed if the coronary ostium was involved. Results All patients recovered from the operations uneventfully, and were followed up from 6 months to 3 years. All patients were in New York Heart Association（NYHA） functional class Ⅰ or Ⅱ during the follow-up period, and paravalvalar leakage, pseudoaneurysm and aortic root aneurysm were not found by the examination of 3D computed tomographic angiography and echocardiography at 6 months（4 cases）, 1 year（2 cases）, and 3 years（1 case）, respectively . Conclusions Supra-annular AVR is an alternative surgical method for patients with severely damaged aortic annulus. The procedure is simple and effective to prevent paravalvular leakage and pseudoaneurysm formation.
