[Modified Fontan's operation].

Nine-year-old female patient presented with cianosis since she was born, fatique and dyspnea when sucking. The diagnosis was univentricular heart with left ventricular morphology, transposition of the great arteries, moderate pulmonary valve stenosis and atrial septal defect. Submitted to surgical correction with superior vena cava-right pulmonary artery anastomosis, inferior vena cava anastomosis using lateral tunnel, with cardiopulmonary bypass. After surgical correction, the clinical and laboratorial (echocardiogram and cardiac catheterization) evaluation showed Fontan operation with good surgical results. Total cavopulmonary connection was proposed as a modification of the Fontan procedure that might have greater benefits than previous proposed techniques. The results demonstrate that this modification provides excellent early definitive treatment, increasing hemodynamic profile, with low morbidity and mortality, for a variety of complex congenital heart lesions.

[Ebstein's anomaly associated with interventricular communication].

Twelve-year-old patient, with congestive heart failure and mild, caused by Ebstein's anomaly with interventricular septal defect, was studied and submitted to surgical correction which consisted in covering the interventricular defect with a path of bovine pericardium and substituting for the tricuspid valve with a biological prosthesis (porcine). After surgical correction, the patient was submitted to strict clinical and laboratorial (echocardiogram and cardiac catheterization) evaluation which presented excellent adjustment of the cardiac antriums, with improvement of myocardial function index. The problems related to the diagnosis of the association of the Ebstein's anomaly with interventricular septal defect can be solved with a well done semiology, helped by accurate laboratorial procedures like echodopplercardiogram and cardiac catheterization. The total surgical correction can be achieved with results and, with this fact, change the natural development of the disease.
