title: Massive right-sided cardiac thrombosis in Chagas' heart disease without left ventricular dysfunction.
abstract: A 63-year-old woman with the diagnosis of mega-oesophagus secondary to chronic Chagas' disease and no past cardiac history was referred for cardiac evaluation. The resting ECG showed right bundle-branch block, whereas a 2-D echocardiogram revealed marked right ventricular dilatation with hypokinesia, right atrial dilatation, normal pulmonary artery pressure, and normal left ventricular ejection fraction. A large, irregularly shaped mass, arising from the right atrium and protruding into the right ventricle through the tricuspid valve, with several different bizarre forms inside the right atrium during systole and/or diastole was seen on 2-D echocardiogram. Therefore, massive right-sided thrombosis can be detected in Chagas' disease patients with no overt right- and left-sided ventricular failure.
