title: Pseudoaneurysm of the ascending aorta 31 years after mitral valve replacement.
abstract: We describe a rare case of an ascending aortic pseudoaneurysm 31 years after mitral valve replacement with a Björk-Shiley mechanical valve. The aneurysm presumably expanded gradually during the years following surgery. As the valve was functioning normally, it was left in situ while the ascending aorta was replaced. This report provides valuable information regarding the long-term nature of this patient's pseudoaneurysm, and the long-term durability of the Björk-Shiley spherical valve in the mitral position.
