Prosthetic valve thrombosis-case report and literature review.

Prosthetic valve thrombosis (PVT) is a dreaded complication of patients with mechanical valves, particularly those in the mitral position. The diagnosis is based on the clinical presentation, supported by echocardiography. As it provides a sustained benefit with low rates of embolization, thrombolyic therapy is a good non-invasive alternative to surgical therapy for carefully selected patients.
