Why the study?
Fracture of the mitral prosthesis in Björk-Shiley valves can cause acute left ventricular failure and requires prompt diagnosis and intervention.

Echocardiography may enable rapid diagnosis of rare prosthetic strut fracture; leaves open its role in routine surveillance of Björk-Shiley valves.
A 40-year-old man with Björk-Shiley valves implanted in the aortic and mitral positions nine months previously presented with central chest pain. Shortly after admission he developed clinical features consistent with left ventricular failure. Fracture of the mitral prosthesis was diagnosed by echocardiography. At emergency operation the outlet strut of the mitral valve was found to be fractured and the disc was in the left ventricle. The patient survived valve re-placement and is in good health four years later.
