[The direct closure of interventricular communications in infants].

The authors report the greatest number of cases of closure of Inter-Ventricular Communication of the newborn published to date. The use of the new technique of deep hypothermia and extra-corporeal circulation, together with the improvement of post-operative care, have permitted them to obtain results which are particularly satisfactory.

[Surgical correction of ventricular septal defects treated by banding the pulmonary artery. Apropos of 38 cases].

The authors report their experience with two-stage surgical treatment of severe ventricular septal defects in babies: initial banding of the pulmonary artery, followed by closure of the ventricular septal defect and removal of the band by an open-heart technique. Out of 162 operations to band the pulmonary artery, 90 were for cases of ventricular septal defect. The mortality was low (9.1%) when there was a ventricular septal defect with or without a patent ductus. It is considerably higher (31.4%) when there is a coincident coarctation of the aortic isthmus. So far 38 children have had the second operation, with 2 deaths. The authors have studied the surgical problems and the long-term results (6 months to 3 years follow-up) in the first 29 patients undergoing surgery. Although the results from this two-stage operation are good, when the authors take into account their current experience with one-stage closure of ventricular septal defects in the babies, they feel that this latter technique is to be preferred. Reservations must, however, be expressed when the child is very young (Weighing 3.5 kg or less), when there are multiple defects between the ventricles, and when the defect is severe, with a combination of VSD, patent ductus and coarctation of the aorta, and sometimes when the opertion must be carried out as an emergency.

[First stage closure of badly tolerated ventricular septal defects in the infant].

The authors report their experience of one-stage closure of poorly-tolerated ventricular septal defects in small children and babies. They use both extra-corporeal circulation and profound hypothermia. The results which they present have been very encouraging. They emphasise the fact that the closure is not complete after surgery, and that most of the murmurs which persist post-operatively disappear gradually. Of the neurological defects which were seen in two cases after surgery (one after profound hypothermia and one after extra-corporeal circulation) one resolved completely; in the other (in which there was a cardiac arrest followed by cardiac massage for one hour) certain intermittent visual defects have persisted. All of the other children can now be regarded as normal.

[Surgical treatment 0f 52 obstructive cardiomyopathies. 11-year experience (1964-75)].

The authors present their 11 year experience of treating severe cases of obstructive cardiomyopathy which were resistant to medical treatment. They consider that myotomy is the simplest procedure (it is always effective) in this mysterious disorder for which it must be admitted that there is no treatment that is entirely satisfactory.

[Left ventricular perforation after insertion of a mitral prosthesis. 6 cases].

The external ruptures of the left ventricule occuring in the first twelve postoperative hours and demonstrated by a disastrous haemorrhage or cardiac failure, the other traumatics accidents could be delayed and be observed during the first month, or even later. Essentially two mechanisms are implicated: -- Direct traumatism by a ball valve on the ventricular septrum. -- Sub-annular splitting in connection with the excision of a piece of calcareous valve. Two lines of approch can be offered to avoid these accidents: -- Choose a disc valve when the surgeon finds a small left ventricle below a stenosed and calcified mitral valve. -- Care in the decalcification of the mitral ring and the valvular resection, leaving in case of need a small calcified cuff for safety. The analysis of these findings clarify the main causes of left ventricular rupture after mitral replacement, rare complications, but ones which are very real.

[Atrio-ventricular canal. Apropos of 47 operated cases].

The authors present their experience of this "bad reputation surgery". The operations performed ranged from pulmonary artery banding to complete reparation of A and B forms. They insist on the value of the assessment during operation of the quality of valvular repair.
