Direct drainage of the right pulmonary veins into the coronary sinus with intact interatrial septum: a case report.
Partial anomalous pulmonary venous connection to the coronary sinus is rare. This anomaly is even more rare in the absence of interatrial communication. Usually, the anomalous right pulmonary veins drain to the right atrium or venae cavae, while the anomalous left veins connect to the coronary sinus or left innominate vein. The present report is the first in the English literature to document a situs solitus case in which all three right pulmonary veins drained directly into the coronary sinus without an atrial septal defect. Closure of the coronary sinus orifice and unroofing of the coronary sinus into the left atrium is a safe and effective way of treating this anomaly.
