RESUMO
A case of right ventricular tumor in a 14 year old male is presented. Congestive heart failure and a systolic pulmonary murmur due to right ventricular obstruction were the main symptoms. The diagnosis was confirmed by echocardiogram (M mode) and right ventricular angiography. The surgical treatment was curative and the histological exam revealed a myxoma.

Forty-two cases of preterm infants with respiratory distress syndrome who developed congestive heart failure secondary to large arteriovenous shunt across permeable ductus arteriosus and who were treated with indomethacin are presented. The cases were divided into three groups according to birth weight: group I less than 1,200 g, group II between 1,250 and 2,000 g and group III from 2,000 to 2,500 g. Satisfactory results were obtained by either ductal closure or by important reduction in the left to right shunt with disappearance of the congestive failure in 37.5% of group 1, 71% in group II and 69% in group III. We concluded that indomethacin is the treatment of choice for patients weighing more than 1,050 g and over 30 weeks gestational age and that surgical ligation is the treatment of choice in patients under this weight and gestational age.

A case of a two year old child with atrial flutter diagnosed at four months of age is presented. The child also had a large atrial septal defect. We were not able to convert the atrial flutter to sinus rhythm with medical treatment of electroshock. However, it did respond to mechanical stimulation during cardiac catheterization. The atrial septal defect was repaired and the patient has not had a recurrence of the flutter.

Sixteen newborn babies with severe respiratory distress and patent ductus arteriosus with congestive heart failure are presented. Fifteen of them were premature and one at full term. Management consisted of the accepted medical and ventilatory aids such as digitalis, diuretics, ventilators, etc. Thirteen cases were given indomethacin with clinical closure in five of them (38%). Ten cases underwent surgical closure with 30% mortality. It is recommended that these patients be given indomethacin inicially; if there is no response in 36 hours surgical closure of the duct should be performed prior to progressive deterioration and eventual death.

The author's experience in the association of right aortic arch and congenital cardiac malformations is reported. We found 56 cases out of 1200 congenital cardiac malformations which constitutes 4.6%. In the classification of Knight and Edwards, type I right aortic arch was the most frequent (96%) and it was associated principally with Tetralogy of Fallot (46%), transposition of the great vessels (14.3%), truncus arteriosus (12%), tricuspid atresia (10.7%) and complex cardiac malformations associated with the syndrome of visceral heterotaxy (10.7%). In type II and type III we found only one case of each and these were associated with pulmonary valvular stenosis, atrial septal defect and ventricular septal defect. It is noted that the right aortic arch has never been associated with total anomalous pulmonary venous return nor with mitral or aortic valvular malformations.
