  • Title: [Three cases of aortic root replacement by cryopreserved homograft with effective usage of its anterior mitral leaflet].
    Author: Shin H, Farnsworth A, Spratt P.
    Journal: Nihon Kyobu Geka Gakkai Zasshi; 1993 Jan; 41(1):101-4. PubMed ID: 8459127.
    Abstract:
    Homograft aortic root replacement was done to three patients and the anterior mitral leaflet of the homograft was used with success in all cases. Case 1. A 37-year-old man had late-onset active prosthetic valve endocarditis with a fistula from the aortic annulus to the left atrium. The fistula was closed by using a homograft anterior mitral leaflet and the aortic root was replaced by a homograft with reimplantation of the coronary arteries. He is very well without evidence of recurrent endocarditis 29 months after the operation. Case 2. A 37-year-old man had early-onset active prosthetic valve endocarditis and developed the same fistula as case 1. He was treated successfully as in case 1. He is very well 4 months after the operation. Case 3. A 50-year-old woman, who had undergone aortic commissurotomy due to aortic valvular stenosis fifteen years before, deteriorated again. She had subvalvular membranous stenosis and a small aortic annulus. Konno-Soma procedure was applied to enlarge the annulus and the aortic root was replaced by a homograft. The interventricular septal incision was closed successfully with use of the anterior mitral leaflet of the homograft. Homograft aortic root replacement was an attractive procedure for prosthetic valve endocarditis or a small aortic annulus, and the homograft anterior mitral leaflet was useful for closing the fistula due to the infection and for closing the interventricular septal incision of Konno-Soma procedure.
