A 61 year-old man was admitted with fever and chest discomfort. He had undergone aortic root replacement for annuloaortic ectasia at age 57. Computed tomography showed a pseudoaneurysm and an abscess formation around the aortic root. Prosthetic valve endocarditis was diagnosed and the underwent repeat aortic root replacement. After debridement and irrigation of the abscess cavity, the left ventricular outflow tract was reconstructed with an equine pericardium, which was rolled to form a conduit. The pericardial conduit was securely sutured to the healthy left ventricular wall and the mitral annulus. A 25 mm-Freestyle valve was then sutured to the distal end of the conduit. The previous prosthetic vascular graft was removed and Completely replaced with a new prosthesis. This method provided secure fixation of a new prosthetic valved conduit to the normal left ventricular tissue with an excellent operative visual field.
