Echocardiographic diagnosis of a left atrial thrombus in a patient with normal prosthetic mitral valve.
A 20-year-old male with a Björk-Shiley mitral valve prosthesis on optimal anticoagulation and antiplatelet drug therapy presented with systemic embolization 11 months after mitral valve replacement. Cross-sectional and Doppler echocardiography revealed a left atrial thrombus attached to the posterior wall of the left atrium and normal function of the prosthetic valve. The findings were confirmed at surgery.
