Echocardiograms were recorded in two patients with suspected aortic root dissection. In the first patient with a massive pulmonary embolus, a simultaneous recording of the mitral ring and posterior aortic wall created a pattern similar to true posterior aortic wall dissection; in the second patient with severe generalized atherosclerosis, thickened aortic walls recorded echocardiographically we...

are presented.
