Stuck Bioprosthetic Aortic Valve--A New Entity? A Case Report

Abstract

We describe herein a case of bioprosthetic valve malfunction, which closely imitates a stuck valve. Although the term "stuck" was used originally for the immovable mechanical valve leaflets, the echocardiographic manifestation of this malfunction is similar to those of a mechanical one. The clinical presentation of the stuck bioprosthesis is, however, far more benign than a stuck mechanical valve. Familiarity with this entity is important.
