Right ventricular regional wall motion abnormality in congenital heart disease.

Four cases of congenital heart disease with right ventricular overload and echocardiographic evidence of persistent right ventricular regional wall motion abnormalities are presented. Right ventricular infarction could be a possibility. Such regional wall motion abnormalities could add to overall right ventricular dysfunction in these cases. Echocardiography is useful in diagnosis. Right ventricular wall motion abnormalities should be studied in detail in all cases of congenital heart disease with right ventricular overload.
