The aim is to compare effective growth true hypoplastic pulmonary arteries using Right Ventricle Outflow Tract Reconstruction by femoral allogenic vein valve conduit and systemic-to-pulmonary artery shunts (modified Blalock-Taussig shunt)

The use of femoral allogenic vein valve conduit for Right Ventricle Outflow Tract Reconstruction is good alternative systemic-to-pulmonary artery shunts (modified Blalock-Taussig shunt). Main advantages is straight, symmetrical, pulsating, systolic blood flow in hypoplastic pulmonary artery, which stimulate growth and prepares for a radical repair. Taking into account the absence randomized studies in this area of medicine, providing investigation evaluating parameters of safety for both methodics is very actual.
