title: Stenosis of the coronary sinus ostium. An unusual site of obstruction in total anomalous pulmonary venous drainage.
abstract: A patient with total anomalous pulmonary venous connection to the coronary sinus and stenosis of the right atrial opening of the coronary sinus is described. While the initial studies were compatible with increased pulmonary blood flow, subsequent evaluation demonstrated severe pulmonary venous obstruction. Successful operative correction was performed.
