Impact of prenatal diagnosis on outcomes of surgical correction in newborns with transposition of the great arteries comparing to other critical congenital heart defects

Abstract

A review of the literature data describing the influence of prenatal diagnosis of critical congenital heart defects on perioperative and long-term results is presented, with a focus on the features of prenatal detection of transposition of the great arteries. This heart defect is a convenient object of studying due to the relative anatomical homogeneity of the nosological form; the birth of patients, as a rule, at full term; the rarity of the combination of this pathology with multiple congenital malformations and chromosomal abnormalities that can potentially worsen the results of treatment; the similarity of the principles of preoperative management in this category of patients in different clinics; the performing of arterial switch surgery in a strictly defined time frame (usually during the first month of life); the relative similarity of surgical techniques used. The relevance of this study is to identify patterns that make it possible to improve existing protocols for the treatment of newborns with transposition of the great arteries and create new algorithms for interaction between gynecologists, neonatologists, resuscitators, and cardiac surgeons.
