A case of aortic prosthetic valve endocarditis with aortic root aneurysm

A 72-year-old male who underwent patch closure of atrial septal defect and aortic valve replacement (AVR) 10 years ago was diagnosed as aortic prosthetic valve endocarditis for recurrent fever, coexisting paravalvular leakage and aortic root aneurysm by transthoracic and transesophageal echocardiography. Operative findings showed mechanical prosthesis was dehiscenced in part and limited subannular aneurysm that was healed macroscopically. The hole of the aneurysm was closed by direct suture. Re-AVR, mitral valve replacement and tricuspid annuloplasty for complicating mitral valve stenosis and regurgitation and tricuspid valve regurgitation was performed. The patient is now doing well for one year after the reoperation.
