title: [Influence of reconstruction of right ventricle outflow tract to the results of radical correction of tetralogy of Fallot].
abstract: We wanted to compare results of different methods of correction of right ventricle outflow tract (RVOT) obstruction. In our clinic 259 radical corrections of tetralogy of Fallot were performed from 1984 till 2002. Age of patients from 1 and a half-year to 55 years; 42 from them were children till 3 years age. One hundred twenty nine were primary corrections and 130 after palliative procedure. We divided patients into 6 groups. First group 83 cases - RV reconstruction with pericardial patch. II(nd) group 27 RV reconstruction and commisurotomy of PA. III(rd) group 97 cases RVOT reconstruction with transannular patch. IV(th) group - 30 cases. RVOT reconstruction with monocusp patch. V(th) group - 16 cases - we had used homograft conduit from RV to PA. VI(th) group - reconstructions were made through right atrium incision - 6 cases.
  
  
  RESULTS
  Early postoperative mortality 13.2% In I(st) group 10 (12%) patients died, in II(nd) group 3 (11.1%), in III(rd) - 14 (14.4%), in IV(th) - 4 (13.3%) and in V(th) - 3 (18.7%). In group VI nobody died. Main reason of death was acute heart insufficiency because of too high residual RV pressure.
  
  
  CONCLUSIONS
  Radical correction of TF may be safely performed for patients of all ages. Early postoperative mortality doesn't depend on way of correction. Main reason of early postoperative deaths is heart insufficiency because of too high residual RV pressure.
