Twenty-eight-year survival of stent-mounted aortic homograft in the mitral position: case report.
The case is presented of a long-term survivor after bioprosthetic valve implantation. A stent-mounted aortic homograft had been implanted in the mitral position, and survived for 28 years before being removed due to a tear in the base of leaflet, resulting in mitral regurgitation. The technique was discontinued in the mid- 1970s following reports of detachment of aortic valve cusps from the stent. The current case report may rekindle interest in the method, and also lead to an investigation of the factors that influence structural deterioration of bioprosthetic valves.
