ABSTRACT

Objective. To describe the features and evolution of affected subjects who underwent surgery, and to determine possible prognostic factors in morbidity and mortality in a short and midterm.
Materials and Methods. This was a retrospective and descriptive study by revision of clinical files of subjects with great arteries transposition who were operated on between 2007 and 2016.
Results. 192 subjects diagnosed with great arteries transposition were selected (105 IVS / 85 VSD). In 127 out of them, a surgical correction during the first surgical procedure was achieved (anatomical 91% / physiological 9%), with a mortality of 22.8%. In 24 patients, the anatomical correction was done after ventricular preparation (mortality of 33.3%). A higher mortality was observed in patients with transposition with aggregates malformations, mainly coarctation of the aorta. In the linear regression analysis, we found significant significance for mortality in the following variables: cardiopulmonary bypass time, aortic cross clamp time, postoperative mechanical ventilation time, and the year operation was performed.
Conclusions. In our institution, the mortality associated with the surgical management of the transposition of the great arteries is higher than the reported in the literature; this is closely related to the learning curve and improvement of the surgical technique over the years.
