ISOLATED DEXTROVERSION - A CASE-REPORT

We report a case of an asymptomatic elderly women who was found to hav e isolated fdextroversion on a routine echocardiogram obtained before induction chemotherapy for acute myelogenous leukemia. On examination, the heart sounds appeared distant, with no other abnormalities. The c hest x-ray showed mildly elevated right hemidiaphragm, an enlarged sil houette, and left pleural thickening. The cardiac workup included an e lectrocardiogram, which was abnormal. An echocardiogram was done to as sess cardiac function. It showed dextroversion without transpositions of the great vessels or any other cardiac malformation; the ventricles appeared to point to the right. A contrast study confirmed the dextro version and normal attachment of the great vessels. Dextroversion was an unexpected finding on an echocardiogram done to assess cardiac func tion before induction chemotherapy. The echocardiogram excluded anteri or wall myocardial infarction and provided the correct explanation for an abnormal electrocardiogram.
