title: Left ventricular outflow obstruction by a mitral valve prosthesis: Doppler ultrasound and cardiac catheterization findings.
abstract: Left ventricular outflow tract obstruction by a mitral valve prosthesis was noted several years following surgery when symptoms of congestive heart failure occurred. The diagnosis was made using two-dimensional echocardiography and Doppler techniques and confirmed at heart catheterization, using micromanometer tipped catheters.
