[Complete correction of Fallot's tetralogy in infants. Preliminary results].

Complete repair was undertaken in 28 infants with severe forms of tetralogy of Fallot because severe cyanosis or anoxic spells. Age at operation ranged from 8 days to 11 months (mean: 4,4 months). Among the 24 cases without any other intracardiac defect, there were 6 early deaths related in 4 cases to a wrong indication or a technical error. Re-investigation was performed in 14 out of the 18 survivors from 3 weeks to 6 months post-operatively: the result is good in 10 cases, fair in 1 case, and poor in 3 cases requiring twice a reoperation with 1 further death and 1 good final result. More accuracy in selecting the surgical patients and improvement in operative techniques should result in a further decrease of our early mortality rate. Primary complete repair should therefore become a substantial alternative to the palliative shunts which results seem to be hazardous in the more severe types of the defect.

[A case of subannular aneurysm of the left ventricle].

The authors present a case of sub-annular aneurysm of the left ventricle in a child of 7. It was associated with aortic incompetence, a ventricular septal defect, and coarctation of the aorta which were discovered during investigation of streptococcal septicaemia. As a first stage procedure, the aortic valve was repaired, the aneurysm was excised, and the ventricular septal defect closed. At a later stage, the coarctation was resected. The question of whether this lesion was congenital or acquired is discussed. After one year, the result remains satisfactory.

[Apparently primary acute heart failure in infants. Long-term outcome].

Cases of acute cardiac failure which are apparently primary, and occurring in babies or young children have one characteristics clinical picture. There are three etiological agents, which cannot be differentiated clinically: myocarditis, fibroelastosis, and primary non-obstructive cardiomyopathies. When the critical early period, which still carries a high mortality, has been passed, the outlook is relatively favourable. 61 babies or infants of less than 30 months with acute primary cardiac failure were followed up for a period of between 5 and 20 years. 33 of them were considered cured; 22 have minor sequelae (most frequently) left ventricular hypertrophy on X-ray or ECG); 3 have persistent cardiac failure despite treatment; 3 have died after a period of more than 5 years. There is no clinical, X-ray or ECG finding which can predict the longterm outlook in this condition. It is virtually impossible to differentiate between myocarditis and firboelastosis; it seems likely in the majority of cases that we are dealing with different modes of development in the same condition.

[Long-term results of 156 Mustard operations for simple transposition of the great vessels].

156 children with simple transposition of the great vessels have been operated on by Mustard's technique between 1-6-1967 and 31-12-1976, with an immediate overall mortality rate of 8%. In the longterm, the 9% of late deaths and more especially the complications are regrettable; complications were either of severe arrhythmia (almost 30%) leading to 2 late deaths and 7 pacemaker implantations, or venous obstruction relating to problems with the patch (25%). Despite the improved techniques and consequent reduction in surgical mortality and late complications, longterm prognosis is still unsure because of the unknown fate of the intra-atrial partition, and that of the "passive" rhythms which are so commonly found after this type of surgery.
