Late surgical repair of ventricular septal defect due to nonpenetrating chest trauma: review and report of two contrasting cases.

Traumatic rupture of the interventricular septum is a rare condition usually presenting in infancy and childhood. This report describes two cases: a 3-year-old boy operated on soon after the diagnosis was made, and a 15-year-old girl operated on 12 years following the causative accident. Both patients had the diagnosis confirmed by cardiac catheterization. The typical appearance of a traumatic ventricular septal defect (VSD) was seen during surgical repair that was successfully carried out in both patients. The protracted clinical course of the second patient, eventually requiring corrective intervention, contributes to the understanding of natural history of traumatic VSD.

[Congenital rubella syndrome and the occurrence of congenital heart disease].

Aiming to document the incidence and type of associated congenital heart disease, 20 children affected with the congenital rubella syndrome have been evaluated during a 5 year period, starting 1988. Congenital heart disease was detected in 45% of the cases. Persistent ductus arteriosus was the most frequent finding, followed by ventricular and atrial septal defects. Hearing disturbances occurred in 83% of the 12 cases studied. Ophthalmic lesions appeared in 69% of the 13 cases analysed, congenital cataracts being the most frequent one. An association of 66% was found between ophthalmic and heart lesions. Regarding the nutritional index, 70% of the cases were situated between the 25th and 50th percentile. The relevant incidence of congenital defects and the documentation of an important number of cases in a short period of time point out to a significant prevalence of the syndrome with imperative need improve the vaccination programs.

[Incidence of heart defects in Down syndrome].

Eighty-six patients with Down Syndrome were studied with the main purpose of quantifying the incidence of congenital heart defects and the risk of occurrence according to the mothers age. Thirty-eight patients had the cariotypes determined, 35 of them having trissomy of chromosome 21 and translocation in 3 cases. Congenital heart disease was found in 44 (51%) of the patients, the most common one being ventricular septal defect. An important incidence of Fallot's tetralogy was also found (20%). These 86 children were submitted to 41 surgical procedures, most of them on the cardiovascular system. The maternal mean age was 33 -/+ 8.6 years and the estimated risk of Down Syndrome was 1/590, a lower value than the one reported in other studies.

[Cardiac evaluation in children with suspected heart disease. Preliminary results in 2000 patients].

Two thousand consecutive children have been evaluated for suspected heart disease in a 27-month period. The main reasons for referral were: murmur (70%), precordial pain (9.5%), suspicion of arrhythmia (8.5%) and breathless (5%). Five hundred and six (25%) cases did not complete the investigation and the results were not computed. A final diagnosis was obtained based on the reason for referral and the main conclusions were: 1) a high incidence of normality was found: murmur (83%), pain (98%), arrhythmia (97%) and breathless (94%); 2) heart disease is unlikely when other referral reasons were analyzed; 3) 14% of the children were considered abnormal and the necessity of therapeutic procedures was 0.8%. A pediatric cardiology outpatient clinic in a public setting seems to be justifiable in the region, due to the high current demand.
