[Double-chamber right ventricle, aortic subvalvular stenosis and interventricular septal defect. Apropos of 12 cases].

The authors report 12 cases of double-chamber right ventricle associated with discrete subaortic stenosis and ventricle septal defect. The statistics derived from 3,292 surgical reports of congenital heart diseases operated on at the Marie-Lannelongue Surgical Center over an 8 years period show that this association is 7 times more frequent than the law of chance. Twenty-two per cent of double-chamber right ventricles had an associated discrete subaortic stenosis and, in 9% of cases of subaortic stenosis a double-chamber right ventricle was observed.

[Outcome of patients with Eisenmenger syndrome. Apropos of 62 cases followed-up for an average of 16 years].

In an era when heart-lung transplantation offers a therapeutic option for patients with Eisenmenger's syndrome, it is important to assess the natural history of this condition. With this objective the authors studied 62 patients followed-up by the same cardiologist. The average follow-up period was 16 years, but 22 patients were followed up for over 20 years.

[Valvotomy and congenital aortic valve stenosis. Long-term results].

Twenty nine patients (average age 11 years) underwent valvotomy for congenital valvular aortic stenosis from 1967 to 1983. The medium and long-term results were analysed retrospectively: 14 children have been reoperated; 11 for restenosis and 3 for aortic regurgitation after an average period of 11 years. Thirteen of the other 15 patients have been regularly followed-up for about 10 years: there are 7 good results, 3 average results and 3 restenoses.

[54 cases of infectious endocarditis seen in 32 years in a population of 2038 congenital heart diseases].

A longitudinal study of a 32-year period (1954-1987) involving 2038 patients with congenital heart defects followed by the same physician yielded 54 cases of infective endocarditis (IE). Complex cyanogenic cardiopathies were particularly exposed to the risk of infection (8.2 IE for 1000 patient-years), then came ventricular septal defects (2.

[Tetralogy of Fallot. 20 years' experience in 144 cases].

Between 1968 and December 1987, 144 patients with tetralogy of Fallot were examined at La Pitié Hospital, Paris. 76 were female and 68 male, with a mean age of 8.1 years at the first visit.
