Abstract Two-dimensional and Doppler echocardiographic findings in 20 patients with double chambered right ventricle are described. All patients had the diagnosis established by cardiac catheterisation and confirmed at operation. Echocardiographic evaluation was done prior to surgical correction. Anomalous muscle bands in right ventricular cavity were detected in 16 patients. Doppler flow velocities in the right ventricular cavity suggested infundibular obstruction to blood flow at a low level in all 17 patients studied by Doppler echocardiography. Ventricular septal defects (11 patients), pulmonary stenosis (3 patients), and aortic regurgitation (3 patients) were detected accurately before operation by echocardiographic examination. Failure to detect the anomalous muscles in right ventricular cavity may occur in adult patients with poor anterior resolution and in those with severe right ventricular outflow obstruction and myocardial hypertrophy. Two dimensional echocardiography with Doppler flow analysis is useful in the evaluation and differential diagnosis of right ventricular outflow obstructions prior to invasive studies and surgical intervention.
