Persistent left superior vena cava-An alternative feasible technique during Senning procedure.

Although rarely performed today in most centers, Senning procedure continues to be a good option for patients with transposition of great arteries presenting late with either regressed left ventricle or pulmonary hypertension. There are many subsets of patients including those having deficient atrial septal tissue, situs inversus, dextrocardia, and atrial isomerism which require complex modifications of technique. One such subset is patients having bilateral superior vena cavae (SVC), which requires coronary sinus cutback and creating a wide flap for the posterior venous baffle which unduly increases the complexity of the surgery. We describe an alternative way of rerouting a persistent left SVC by reimplanting onto the left atrial appendage which forms the part of the systemic atrium after the atrial switch surgery.
