Transthoracic and transoesophageal echocardiographic documentation of disappearance of massive right atrial and pulmonary artery thromboemboli after fibrinolytic therapy and normalization of left ventricular dimensions and function.

In this paper, we report a case of dilated cardiomyopathy with right atrial thrombi and pulmonary artery thromboemboli, in which regression of thromboemboli followed fibrinolytic therapy, and normalization of left ventricular dimensions and function were documented at echocardiographic follow-up. The important role of transoesophageal echocardiography in diagnosis and follow-up of right intracavitary masses and thromboemboli in the main pulmonary arteries is discussed, as is the role of echocardiography in follow-up of cardiomyopathy.
