Methods
We searched the extant literature using the Mesh term “Transposition of
the great vessels”, and the key word “arterial switch”, to identify
the variations in the coronary arterial anatomy as published from 1966
through 2021. The search engines used were PubMed , Google Scholar,
Cochrane Database for Systematic Reviews, Cochrane Central Register of
Controlled Trials, Ovid MEDLINE (all; 31.12.2019), ACP Journal Club,
Ovid EMBASE (1974 to 31.12.2019), Database of Abstracts of Review of
Effectiveness. We searched the literature in all languages, including
reports of mortality subsequent to the switch procedure when coronary
arterial patterns had been described. When overlapping series were
published from a single institution, we selected the studies providing
data on the largest number of patients.
