Acute right ventricular overload: an echocardiographic clue to pulmonary thromboembolism

The Johns Hopkins Medical Journal

Abstract

Serial echocardiographic changes and angiographic correlation are presented in a patient with multiple pulmonary emboli. Interval development of right ventricular dilatation and paradoxical septal motion coincided with a clinical event which was proven angiographically to represent pulmonary thromboembolism. Echocardiographic findings suggested right ventricular pressure and/or volume overload. The differential diagnosis of this finding when acute is limited; pulmonary embolism is a prominent consideration. Echocardiography performed after the patient received anticoagulant therapy showed a complete return to normal. Echocardiographic evidence of right ventricular overload, particularly when acute, may indicate the presence of a pulmonary embolism, and may be clinically useful in selected cases.

Arrhythmogenic Right Ventricular Dysplasia

Arrhythmogenic right ventricular dysplasia is a congenital cardiomyopathy that is characterized by infiltration of adipose and fibrous tissue into the right ventricle wall and loss of myocardial cells. Primary injuries usually are at the free wall of the right ventricular and right atria resulting in ventricular and supraventricular arrhythmias.
