title: Aortopulmonary window with anomalous origin of the right coronary artery from the pulmonary artery: two cases highlighting the importance of complete pre-operative echocardiographic evaluation of the coronary arteries in all conotruncal anomalies.
abstract: This report describes two infants with an aortopulmonary window in association with anomalous origin of the right coronary artery from the pulmonary artery. In both cases the diagnosis was made pre-operatively by transthoracic echocardiography, with the initial clue being extensive collateral flow within the myocardium. In each case there was surgical confirmation of the echocardiographic findings. These two cases demonstrate that coronary artery evaluation should be an integral part of every new echocardiographic evaluation, particularly in the setting of conotruncal anomalies.
