Localized Right Atrial and Right Ventricular Cardiac Tamponade Detected by Transesophageal Echocardiography after Stanford Type A Aortic Dissection Surgery：A Case Report

Abstract

When the cause of circulatory failure cannot be identified by transthoracic echocardiography （TTE）in ICU patients, transesophageal echocardiography（TEE）has been reported to be useful and is recommended in guidelines. TEE may be particularly useful in patients with circulatory failure immediately after cardiovascular surgery, because TTE may not provide good images due to the effects of mechanical ventilation and protective materials on the surgical wound. In this report, we describe the case of a cardiac tamponade confined to the right atrium and right ventricle after Stanford type A aortic dissection for which TEE was useful in diagnosis.
