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.
