Abstract
Congenital heart diseases (CHDs) are a complex of structural anomalies of the cardiovascular system that arise during embryogenesis (2-8 weeks of gestation). CHDs can be isolated or part of complex combined diseases. Epidemiological data indicate a stable prevalence of CHDs at 8-9 cases per 1,000 live births. Postoperative mortality within 30 days after cardiac surgery for CHD correction averages 3.5-4%, increasing to 8-9% in neonates. Tetralogy of Fallot (ToF) is one of the most common cyanotic CHDs, with an incidence of 3-5 per 10,000 live births. Morphologically, TF is characterized by right ventricular outflow tract stenosis, interventricular septal defect, aortic decstraposition, and right ventricular hypertrophy. The combination of these anomalies leads to a decrease in pulmonary perfusion and a disruption of systemic hemodynamics, manifesting as chronic hypoxemia. The severity of hemodynamic disorders is a key factor determining the clinical picture and surgical treatment tactics.
Key words
Tetralogy of Fallot, cardiovascular adaptation, postoperative period, hemodynamics, right ventricle, arrhythmias, echocardiography.
