Damus-Kaye-Stansel procedure in the case of an anteroposterior relationship of great vessels.

This video tutorial demonstrates a Damus-Kaye-Stansel procedure performed concomitantly with a bidirectional cavopulmonary shunt in a patient with a double inlet left ventricle, malposed great arteries, and a ventricular septal defect. Given the anteroposterior relationship of the great vessels, the DKS anastomosis was performed using a "double-barrel" technique with patch augmentation. Postoperative evaluation confirmed a widely patent systemic outflow tract and preserved semilunar valve integrity. The patient remains clinically stable at the 6-month follow-up.
