[Results of surgical correction of ventricular septal defects in infants].

Of a consecutive series of 91 babies aged less than 2 years, operated on for closure of a ventricular septal defect during the last four years, the 61 cases with a minimum post operative follow up period of 18 months were retained for review. Closure of the ventricular septal defect was carried out directly 41 times, and after pulmonary artery banding in the other 20 cases, using deep hypothermia with a short period of circulatory arrest and cardiopulmonary bypass.

[Deep hypothermia on the infant: physiopathology and technics of ECC].

In 81 operations for correction of infants's cardiopathies, authors used, associated with E.C.C., a deep hypothermia allowing a circulatory arrest of an average duration of 52 minutes, according to the technics described by BARRAT-BOYES in 1971. From this experience, authors study the modifications brought to the organism by this hypothermia, and discuss the technical aspects in pre, per and post-operative periods. Mortality of this series is of 13,5 p. 100. It is in relation with the cardiopathy or it's correction, without anu possibility or directly charge the technique of hypothermia in its determinism. The early mortality includes a bilateral phrenic paralysis, an air embolism, three septic complications and two neurologic complications probably related to a poor thermic repartition. Advantages of this technique concern the possibility to operate in a bloodless field and a diminution of E.C.C. time.

[Value of dacron aortoplasty in the treatment of coarctation of the aorta during the 1st six months of life].

Between September 1st 1974 and June 1st 1976, 12 infants under the age of 6 months have been operated on by a dacron patch aortoplasty for coarctation of the aorta. The associated lesions were a patent ductus arteriosus in each case, a VSD in 8 cases, and a trans-position of the great arteries in 5 cases. A pulmonary artery banding was performed with the aortoplasty in 8 cases, and a Blalock-Hanlon operation in one instance. There were two operative deaths (17 p. 100), amongst them one in a 1400 g premature infant, and a late death (3rd month). Two infants have a clinical aspect of recoarctation. In four infants, the post-operative hemodynamic and angiographic study carried out before the treatment of associated intra-cardiac lesions, shows a good result of the coarctation repair. This particular technique, although not performed as a routine in the infant with coarctation of the aorta, seems to be of interest in the most severe forms of the disease, with diffuse isthmus narrowing and intra-cardiac defects.

[Results of complete correction of various forms of transposition of the great vessels in the infant].

Over the past 3 years, a Mustard operation has been performed in 38 infants aged 30 days to 24 months, among them 29 less than one year of age. There were 27 TGV with intact ventricular septum, 8 TGV and VSD, (isolated in 3, and associated with PS in 2 and with coarctation of the aorta in 3), 2 TGV with isolated PS, and 1 TGV with aorta-pulmonary window. The operation was carried out under deep hypothermia, circulatory arrest and limited by-pass, using a pericardial patch in all cases but one. The operative mortality is 8% (3 cases) for the whole group, 7% in infants less than one year of age, and 3% for all TGV with intact ventricular septum. The long term results are reviewed, with a follow-up of 2 to 36 months (mean 17 months).

[Discussion on therapeutic attitude in Prinzmetal's angina. Apropos of 6 cases].

1. 46 cases of Prinzmetal's angina have been studied: there were 36 males and 10 females, with an average age of 54.6 years. 19 patients (group A) were treated medically, and 12 of these were followed up for more than 6 months (average follow-up period 45.1 months). 27 patients (group B) underwent a coronary by-pass procedure: 22 of these were followed up for more than 6 months after surgery (average postoperative follow-up period 21.6 months). 2. One patient from group A and two patients from group B died, one of them from postoperative renal failure. None of the three deaths could be attributed directly to the coronary artery disease. 2 patients from group A and 5 patients from group B had a myocardial infarction without fatal outcome. 5 of the 12 patients in group A and 16 of the 22 patients in group B were asymptomatic after more than 6 months of follow-up. 3. The treatment policy should take account: - of the prognosis of Prinzmetal's angina, which is on the whole better than that of an unstable angina pectoris of the common type; - of an assessment of the risks in each individual case; these are increased when there is a combination of risk factors for atherosclerosis, and/or severe arrhythmia with syncope, and/or persistant electrical changes in the territory of the anterior descending artery, and/or coronary artery lesions involving two or three major vessels. 4. Surgery is used if there is a failure of treatment with beta-blockers, which are used under cover of a pacemaker when there is a paroxysmal block. If medical treatment is successful, surgery is indicated in high-risk cases.
