Left ventricular thrombus with normal left ventricular function and hyperaggregable platelets in a patient with polycystic disease of multiple organs.

Mural thrombus is a well-recognized cause of systemic embolization. A case is presented where systemic emboli occurred from a mural thrombus in a patient who had no underlying intrinsic heart disease but who had an apparent hypercoagulable state due to hyperaggregable platelets. This mural thrombus was diagnosed by two dimensional echocardiography in which it was observed that the left ventricular wall motion was normal.
