Horseshoe thrombus in a patient with mechanical prosthetic mitral valve: A case report and review of literature

Figure 1 Prosthetic mitral valve thrombosis. A: Transthoracic two-dimensional echocardiogram in apical four-chamber view; B: Transthoracic continuous wave Doppler across mitral valve. Bi-leaflet prosthetic mitral valve seen with echo density, suggestive of thrombus, attached to the atrial side of the bi-leaflet prosthetic mitral valve. The maximum peak gradient across the prosthetic mitral valve is 14 mmHg and mean peak gradient 4 mmHg.
