Abstract
In part 2 we present review about modern palliative endovascular techniques in treatment of infants and small children with tetralogy
of Fallot, in which stenting of the right ventricular outflow tract (RVOT), PDA and balloon valvuloplasty of pulmonary artery valve is
possible. Balloon valvuloplasty of the pulmonary artery valve if followed by a good clinical results and good oxygenation of the arterial
blood, pulmonary artery and annulus growth. Stenting of the patent ductus arteriosus (PDA) is a more appropriate intervention
in patient with anomalous coronary arteries crossing RVOT; in patients with pulmonary arteries hypoplasia and major aorto-pulmonary
collateral arteries; in patients with severe stenosis or atresia of the left pulmonary artery – when the pulmonary circulation is
dependent of PDA. Stenting of the RVOT allows growth and development of the hypoplastic pulmonary arteries due to adequate
antegrade blood flow. An endovascular palliative method allows quick clinical stabilization of the patients due to elimination of the
arterial hypoxemia and may be considered as an alternative to palliative surgical interventions in certain group of patients.
