[Use of valved tubes in the treatment of ventriculo-pulmonary discontinuity. Long-term results].

Forty five patients, 2 months to 42 years of age, had valved tubes implanted for ventriculo-pulmonary discontinuity. The underlying malformations were: certain forms of Fallot's tetralogy (16 cases), transposition of the great arteries with ventricular septal defect and pulmonary stenosis (8 cases), truncus arteriosus (9 cases), double outlet right ventricle (6 cases), other malformations (4 cases). Hospital mortality (at 30 days) was 31% (14 cases). This was mainly due to technical difficulties related to the large number of palliative procedures and to irreversible pulmonary hypertension, present in 43% of cases with fatal outcomes. Thirty one patients were followed up for 6 months to 7 years (mean 3 +/- 1,6 years). There were 3 late deaths, one during reoperation for a residual shunt. All survivors underwent clinical assessment with hemodynamic control in 17 cases (15 routine control catheterisations). To date it has only been necessary to change one valved tube: a good result was obtained.

[Cardiopathies in trisomy 21. Therapeutic indications].

Approximately 50% of patients with Trisomy 21 have congenital heart lesions and they account for 2.7% of the admissions to the Pediatric Cardiac Unit of the Cardiac Hospital of Lyons. In a series of 91 cases observed over a 10 year period (1070-1980) undergoing hemodynamic and angiographic investigation, 9 out of 10 cases - as previously reported - had the following abnormalities: endocardial cushion defect, 42.7% (39% of which were complete atrioventricular canals), ventricular septal defect, 33%, and Fallot's tetralogy, 12%. These lesions were characterised by the high incidence and precocity of pulmonary hypertension (69 out of 72 cases with a left-to-right shunt . A comparison of the hemodynamic data of children with Trisomy 21 with ventricular septal defects, and children without Trisomy 21 of the same age with ventricular septal defect showed the pulmonary arterial resistances to be significantly higher in the group with Trisomy 21, suggesting that Trisomy 21 plays a role in the pathogenesis of severe early pulmonary hypertension. The operative risk is much higher in these patients, especially with openheart surgery (4 operative deaths out of 12 cases of closure of VSD). The surgical indications are difficult to define because of the context of malformation and mental retardation, the high incidence of pulmonary hypertension and the high opertive risk requiring a large and detailed dialogue with the family.

[Right pulmonary artery-left atrium communication : a rare cause of refractory hypoxia in newborn infants].

Two cases of right pulmonary artery to left atrium in the newborn are described. Both patients presented with refractory hypoxemia cardiomegaly, hypovascular lung fields. Moreover one patient presented with continuous murmur and localised X-ray shadow. Echocardiographic left atrium enlargement suggested diagnosis and angiography confirmed it. Spontaneous improvement in one child is due to a decrease in pulmonary vascular resistance and has allowed the patient to attain an age and a weight in which surgical ligation has been performed more safely.
