title: The square left ventricle: an angiographic and radionuclide sign of left ventricular thrombus.
abstract: The association of mural thrombus with left ventricular aneurysm is well documented, though angiographic documentation of left ventricular thrombus can be difficult. The authors describe the unique appearance of the left ventricular cavity in 5 patients. In all cases, ventriculograms obtained in the right anterior oblique position showed a squared apex. In 2 patients this phenomenon was also demonstrated by radionuclide angiocardiography. All 5 patients were found to have left ventricular thrombus at operation or autopsy.
