ABSTRACT

Objective. Tetralogy of Fallot is one of the most frequent causes of congenital heart disease, ranking fourth in frequency of all congenital heart diseases worldwide. At the Hospital Infantil de Mexico, 272 cases had been operated on until 1996. Of the patients operated with the transannular patch technique, 53% progressed from moderate to severe pulmonary insufficiency. The aim of this study is to document the immediate postoperative evolution in those patients who underwent total correction and monocuspid valve placement in the immediate postoperative period. Material. A comparative, descriptive, prospective, observational, prospective study was carried out, in which 16 patients who underwent total correction of Tetralogy of Fallot and transannular patch placement were studied. During the period going from March 1, 2013 to March 31, 2015, a total of 40 total corrections of tetralogy of Fallot were reported, of which 18 of them were corrected with transannular patch. Two groups were analyzed, the first one made up of 9 patients who underwent monocuspid valve placement, and the second group made up of those individuals who did not undergo monocuspid valve placement. Results. The results suggest a clinical improvement in the immediate postoperative evolution, a shorter stay in the postoperative Intensive Care Unit (p=0.2), a tendency towards a decrease in the need for inotropic support (p=0.3), as well as a decrease in ventilation (p=0.7) and other morbidity variables that are not specifically analyzed. The length of hospital stay indirectly reflects the recovery and stability of the patient. The statistical analysis performed did not show significant differences in the variables analyzed, probably due to the number of patients included and the associated complications. Conclusions. Transannular patch implantation with modified monocuspid valve in right ventricle outflow tract reconstruction for total correction of Tetralogy of Fallot is actually simple and reproductible.
