[Follow-up of patients treated by conduits between the right ventricle and the pulmonary artery].
Between 1981 and 1998, 77 right ventricle-pulmonary artery conduits were implanted in 67 patients (37 boys, 30 girls, average age 6.3 years; range: 3 months to 17 years). The diagnoses were transposition of the great arteries with ventricular septal defect and obstruction of the pulmonary outflow tract (N = 22), tetralogy of Fallot (N = 16), truncus arteriosus (N = 9), double outlet right ventricle with pulmonary stenosis or atresia (N = 8) and agenesis of the pulmonary valve with pulmonary stenosis (N = 2). The implanted conduits were homografts in 50 cases (43 aortic and 7 pulmonary), 11 valved Dacron grafts, 4 valved polystans grafts and 2 non-valved conduits. ⋯ The causes of replacement were pure stenosis (54.5%), pure regurgitation (9%) and mixed stenosis and regurgitation (27.2%). These results are comparable to other published series showing a 15 year survival rate of 65% and a 59% reoperation rate at 15 years. Homografts have a slightly longer life compared with valved Dacron conduits but the difference is not statistically significant.

Interest has recently risen regarding thiamine deficiency (beriberi). In industrial countries, not only alcoholics, but also deprived people with malnutrition, elderly patients and patients with AIDS are at risk of thiamine deficiency. ⋯ Cardiovascular (wet beriberi) manifestations of thiamine deficiency are characterized by peripheral vasodilatation with increased cardiac output, myocardial lesion, sodium and water retention and biventricular myocardial failure. Treatment consists of thiamine administration with rapid clinical improvement after supplementation.

Case Reports[Aortic dissection at 6 months gestation in a women with Marfan's syndrome. Simultaneous Bentall intervention and cesarean section].
A 31 year old woman with Marfan's syndrome had a dilatation of the aortic root (55-60 mm at the beginning of pregnancy). Pregnancy was continued with beta-blocker therapy and with regular echocardiographic follow-up. ⋯ The mother and baby girl are well two years later. The problems of pregnancy in patients with Marfan's syndrome are discussed.
