Cylindrical patch repair for circumferential subvalvular abscess due to prosthetic valve endocarditis

: A 51-year-old male underwent aortic valve replacement and vascular prosthesis implantation due to an aneurysm of the ascending aorta combined with aortic regurgitation caused by the bicuspid aortic valve. Semi-emergency surgery was performed due to severe paravalvular leakage with prosthetic valve endocarditis 16 months after the 1st operation. The circumferential annular abscess cavities were closed with a cylindrical patch, and a mechanical valve was installed on the upper edge of the sutured cylindrical patch. A vascular prosthesis was reimplanted to the ascending aorta. Use of the cylindrical patch provides a good exposure of operative field to close circumferential annular abscess cavity.
