Usefulness of Doppler echocardiography in diagnosing right ventricular coronary arterial communications in patients with pulmonary atresia and intact ventricular septum and comparison with angiography.

Direct and indirect evidence of right ventricular coronary arterial communications has been detected by use of 2-dimensional and Doppler echocardiography in patients with pulmonary atresia and intact ventricular septum. We describe additional consistent and reproducible Doppler echocardiographic findings that were useful for identifying patients in whom abnormal coronary arterial flow patterns were detected angiographically.
