Conclusions
Even in the current era, an intramural arrangement, or origin of the
three major arteries from the same sinus, remains associated with
adverse events following the arterial switch procedure. Optimizing the
technique for translocation of these challenging variants be crucial to
reducing these ongoing problems. The creation of the International
Congenital Heart Surgery Registry to address the issues of
reimplantation, having categorised the patterns present used an
all-inclusive system such as the original Leiden
convention,8 may now provide the data needed to answer
the persisting questions.
