Is coronary artery transfer still the jugular for the arterial switch operation?

The outcomes of the arterial switch operation have improved over a period of time with the elimination of coronary artery anatomy as a risk factor for operative mortality in some series. However, cumulatively, when all the series published so far are analyzed, two coronary variations, namely the single sinus coronary artery origin and intramural type, persist as risk factors for an adverse operative outcome.
