Abstract
The endocardial anchoring technique is a novel modification of total anomalous pulmonary venous return repair that involves creation of an L-shaped flap of the pulmonary venous confluence, subsequently anchoring it to the endocardium. A wide and smooth pathway can be expected from the theoretical advantages of this technique, namely, a smooth inner surface of the anchored flap and traction force to extend the orifice of the connection. An application of this technique for a rare variant of supracardiac total anomalous pulmonary venous return suggests its potential to be an alternative to the conventional repair, especially in patients with a curved pulmonary venous confluence.
