title: The Senning procedure as part of the double-switch operations for congenitally corrected transposition of the great arteries.
abstract: Anatomic correction of congenitally corrected transposition of the great arteries (ccTGA) has brought about the renaissance of the atrial switch. The Senning procedure has become the most widely used variant because of the lower incidence of pathway obstruction, baffle leak, and significant late arrhythmias. It is for this reason the Senning is discussed in detail here. The technical steps of the Senning are both ingenious and unique amongst cardiac surgical procedures. They must be made as safe and reproducible as possible because the procedure is no longer commonly performed and trainee surgeons may have only very limited exposure to these types of operation. In addition to its infrequency, there are additional technical issues regarding the atrial switch in the setting of ccTGA, particularly in relation to associated malposition of the heart and the conduction system. Outcomes for the Senning procedure in ccTGA have been very good, with early complications being extremely rare. Obstruction to the superior vena cava pathway has been recorded in less than 3% of cases and can usually be managed by interventional catheterization. Late problems with atrial arrhythmias have not been widely reported, but this may reflect the relatively short follow-up for these patient cohorts compared with older series in d-TGA.
