Björk-Shiley mitral valvular dehiscence. Documented by radiography, echocardiography, fluoroscopy, and cineangiography.

This case report presents combined radiographic, echocardiographic, fluoroscopic, and cineangiographic findings of the dehiscence of a Bjork-Shiley mitral prosthetic valve. The valvular dehiscence was confirmed at surgery. A distinct rounding of the opening phase of the valve was recorded on the echocardiogram. Other clinical evidence, documenting the severe valvular dehiscence, is reported in detail. Non-invasive procedures are therefore invaluable in recording prosthetic valvular dysfunction.
