Why the study?
Evaluation indices are used to predict intra-operative requirements and post-operative course in TOF, prompting the description of a novel pulmonary vein index indicator.
Does a higher pulmonary vein index predict a smooth post-operative recovery without low cardiac output syndrome in pediatric patients undergoing surgical correction of TOF?
Does a higher pulmonary vein index predict a smooth post-operative recovery without low cardiac output syndrome in pediatric patients undergoing surgical correction of TOF?
A novel pulmonary vein index derived from preoperative computed angiography may help predict post-operative recovery and the absence of low cardiac output syndrome in children undergoing Tetralogy of Fallot repair.
Tetralogy of Fallot (TOF) is a common cyanotic congenital heart disease. Its surgical correction requires ventricular septal defect (VSD) closure and right ventricular outflow tract obstruction (RVOTO) relief, with transannular patch enlargement (TAPE) of the pulmonary valve. The first successful repair of TOF was reported in 1954 and consisted of closure of the VSD through a large right ventriculotomy, and RVOTO relief with TAPE of the pulmonary valve. To predict the intra-operative requirements and post-operative course of patients with this condition, various evaluation indices are available that can provide a good indication of patient prognosis. In this case report, we describe a novel pulmonary vein index (PVI) indicator that offers prognostic indications for pediatric cardiac patients who have undergone surgical correction of TOF.
