title: Double connections in total anomalous pulmonary venous connection.
abstract: Three infants who underwent operation for total anomalous pulmonary venous connection had unobstructed drainage of all the pulmonary veins to both the coronary sinus and left vertical vein. In one patient the anatomy was demonstrated preoperatively and complete correction accomplished without difficulty, but in two patients the second connection was discovered only at postoperative reinvestigation. Arbitrary classification of total anomalous pulmonary venous connection into cardiac, supracardiac, infracardiac, and mixed types does not lend itself to description of such lesions and may obscure their clinical importance. For these less common variants of total anomalous pulmonary venous connection, a more detailed and precise definition of morphology facilitates accurate surgical repair.
