The role of the pulmonary artery index in management of surgical treatment of double origyn of the right ventricle vessels (DORVV) of tetralogy type was determined.
Between January 1991 and December 2008, 78 patients with DORVV (tetralogy type) had surgical treatment at the National Amosov Institute of cardiovascular surgery. 221 patients have been made radical correction. The extent of pulmonary artery hypoplasia branches was defined with the help of index of pulmonary artery (IPA).
If IPA>100 mm/m2, a one-stage surgical treatment of DORVV of tetralogy type is accompanied by good results after operation. With IPA<100 mm/m2, during total correction the risk of acute heart failure lethal results increase in an early postoperative period. In these cases two-stage correction of DORVV of tetralogy type is preferred.
