Homograft aortic root replacement for destructive prosthetic endocarditis.
Prosthetic aortic valve endocarditis with extensive destruction of the aortic root, annular abscess formation, and left ventriculoaortic discontinuity was seen in 3 patients, with aorta to left atrial fistula formation in 2. Homograft aortic root replacement with use of the anterior mitral leaflet of the aortic root to repair the fistula was used successfully in all 3 patients. Their case reports are discussed to highlight the use of the homograft aortic root in these complicated cases, and to report the occurrence of aorto-left atrial fistula in prosthetic valve endocarditis.
