Abstract
In order to determine the effect of right atrial dysfunction on, clinical o utcome, size patients with inferior myocardial infarction with extension to right ventricle and right atrium involving only obstructions of the right coronary artery were examined with transesophageal echocardiography (TEE) a t the time of the event. Five of the patients were reexamined 15 to 55 mont hs later. Two patients underwent thrombolysis and maintained ratios of righ t-to-left ventricular diameters of less than 1, as well as normal convexity of the interatrial septum,. One patient had spontaneous reperfusion of the right coronary artery, reduction in right ventricular diameter, and normal ization of interatrial septum. Another patient underwent delayed angioplast y and manifested a diminished wall movement score (WMS) in the follow-up ec hocardiogram,m. One patient died during his first hospitalization. with sig nificant right ventricular dilatation, inverted convexity of the interatria l septum, and right atrial thrombosis. The last patient died during follow- up with right ventricular dilatation, increased WMS, right atrial akinesis, and inverted interatrial convexity. Serial TEE examination of patients wit h infarction of the left ventricular inferior wall is a safe technique for determining the degree of the extension of the ischemic process to the righ t chambers.
