Abstract
The aim of the study was to determine the most significant risk factors of the right ventricular outflow tract obstruction, pulmonary artery stenosis and its branches in the long-term period after the arterial switch operation.
Materials and methods. The analysis of the results of treatment of 248 patients with transposition of the great arteries who was underwent the arterial switch operation. The incidence of the right ventricular outflow tract obstruction, pulmonary artery stenosis in the long-term period. The model for predicting the risk of developing this complication was obtained, the method of multiple logistic regression was applied.
Results. The mathematical model for predicting the risk of developing the right ventricular outflow tract obstruction, pulmonary artery stenosis, which includes the following factors: pulmonary artery reconstruction with ksenopericardium (OR 505.657, p=0.001), diameter of the aortic valve (OR 1.636, p<0.001).
Conclusion. Statistically significant predictors were revealed and a mathematical model for predicting the
risk of the right ventricular outflow tract obstruction, pulmonary artery stenosis in the postoperative period
was obtained, which has a sufficient level of statistical significance and predictive ability.
