Stenting right ventricular outflow tract in newborns and patients with tetralogy of Fallot

The article looks at a few cases of stenting the right ventricular outflow tract (RVOT) as a possible alternative to aortopulmonary bypass in staged surgical treatment of adult patients and newborns with tetralogy of Fallot (TF). A comparative analysis of technical support and outcomes in adult and neonatal patients is performed. Emphasis is placed on the importance of endovascular techniques in treatment of patients with TF and the causes of a failure of intervention in adults. RVOT stenting in TF adult and newborn patients is found to be technically feasible, but it is essential to take into account the expressed hypertrophy of the right ventricle in adult patients, which requires the use of optimal stent length and diameter with high radial resistance.
