Prosthetic valve obstruction with normal disk motion: usefulness of transesophageal echocardiography to define cause.
We describe a rare case of Björk-Shiley prosthetic valve obstruction with normal motion of the tilting disk. The cause of obstruction was the annular pannus ingrowth and was well defined by transesophageal echocardiography, but not by cardiac catheterization nor cineradiography.
