[Results of the surgical treatment of congenital mitral insufficiency].

The authors report 21 cases of congenital mitral incompetence undergoing surgery between 1972 and 1977. There were 3 operative deaths and 2 late deaths. Of the survivors, 10 had a good result and 5 a fair result. The factors influencing the results have been associated lesions (aortic stenosis and ventricular septal defects are more serious than atrial septal defects and abnormalities of origin of the left coronary artery), the type of repair (which is better if it seeks to correct the frequently complex valvular abnormality at all levels), and especially the degree of dilatation of the left ventricle. By contrast, age had no influence either on the operative risk or on the quality of the results.

[Correction of cardiac malformations after corrected transposition of the great vessels. A series of 18 cases operated on by an open heart technique].

Recent progress in the surgical treatment of malformations after transposition has been dealt with has been made in three directions: 1. By knowledge of the position of the conducting pathways in relation to ventricular septal defects, so that total atrioventricular block, the first complication of this type of surgery, may be avoided; 2. By appreciation of the proximity of the conductive pathways to the elements contributing to pulmonary stenosis, which may contra-indicate direct removal of such stenosis. In such a case, a valved tube must be placed between the sub-pulmonary ventricle and the pulmonary artery; 3. By appreciating the frequency, the difficulty in diagnosis and the grave consequences of failing to recognise lesions of the atrioventricular valves, with the result that their systematic investigation should form part of the operative technique.

[Neonatal aortic valvular stenosis. Apropos of 8 cases].

Congenital aortic stenosis presenting in the neonate must be distinguished from the commoner hypoplastic left heart-syndrome, which is beyond surgical correction. It is certainly a serious problem, but early diagnosis and supporting angiography to rule out the presence of an associated left ventricular malformation and to check the volume of the left ventricular cavity should lead to a decision to operate. Out a 4 neonates from this series who were presented for surgery, the 2 survivors had good long-term results.

[Closure of ventricular septal defects. Comparison of 2 technics].

To be correctly done, closure of a ventricular septal defect must be sound, and must also avoid damage to the conducting tissue. These two essentials are somewhat contradictory, since in order to avoid the bundle of His in its position along the postero-inferior edge of the ventricular septal defect (VSD) in the membranous septum, the sutures inserted into this region must be superficial, and therefore weak. It is for this reason that the published series continue to show evidence of a significant number of post-operative shunts and atrio-ventricular blocks, as much in the closure of isolated VSDs as in the treatment of Fallot's tetralogy. This paper compares two techniques of suturing the prosthetic material which is used to close the VSD: the classical technique, in which it is intended to avoid the bundle of His by working below it, on the right side of the interventricular septum, and a different technique in which the sutures are applied directly to the free edge of the interventricular communication.

[Ostium primum and mitral cleft and aortic subvalvular stenosis. Apropos of 2 operated cases].

The two case reports are of children of 10 and 8 years of age with an ostium primum defect, with a mitral cleft and a stenotic fibrous ring below the aortic orifice. In the first case, the cause of the obstruction to left ventricular ejection was found at catheterisation, and in the second case it was an operative finding. In both cases there were large gradients, about 100 mmHg. The subaortic blockage was resected in both cases. A review of the literature has not revealed any similar case.

[Pulmonary stenosis with tricuspid insufficiency in the child].

The authors report 3 cases of pulmonary stenosis with an intact interventricular septum and tricuspid incompetence. The tricuspid regurgitation was corrected in all 3 cases. After recalling the clinical features, they emphasize the importance of seeking for this condition and correcting it in every case if the immediate and long-term results are to be satisfactory.

[Cor triatriatum in infants. Four cases with two surgical successes].

Four cases of cor triatriatum are reported in 6 weeks to 23 months old infants. Two were associated with partial anomalous pulmonary venous connection and one with a mild aortic stenosis. Two were successfully operated on and are now normal children: one of these underwent surgery at 3 months with an hemodynamic control one year later. The two others died: the youngest because of an inadequate overloading transfusion, the other soon after pulmonary angiography. Problems in diagnosis and treatment of this rare but very tractable condition are discussed.

[Agenesis of the pulmonary valve associated with interventricular defect].

The association between ventricular septal defect and pulmonary valve atresia is a rare congenital disease, which can provoke the compression of bronchioles, that make a high mortality rate possible in the first years of life. If this syndrome is tolerated, using a convenient medical therapy, it is possible to wait for a more suitable age for a complete correction, which must provide, besides V.S.D. closing, pulmonary valvular substitution by porcine aortic heterograft. The authors also report on their own experience of five cases surgically treated and studied from a pre- and postoperative hemodinamic point of view.

[Reconstruction of the pulmonary outflow tract with a valved conduit (author's transl)].

The authors describe 25 patients who underwent open heart surgery for reconstruction of the pulmonary outflow tract with a valved conduit. The following anomalies were observed: six cases of great vessels transposition, five cases of pulmonary artery atresia, five cases of truncus, three cases of tetralogy of Fallot and six cases of single ventricle. Two cases of single ventricle were treated in order to be transformed into a systemic ventricle. The pulmonary outflow was reconstructed with a valved conduit anastomosed between right atrium and pulmonary artery. This study includes pre- and postoperative hemodynamic values, surgical evaluation and a 5-months to 3-years follow-up. The authors emphasize that it is important that the surgical indications are closely related to the morphology and hemodynamics of pulmonary circulation for a better result.

[Anantomical aspects and surgical treatment of pulmonary stenoses and atresias with intact interventricular septum in the newborn and the infant under 6 months].

The series presented consists of 25 babies (18 of which were neonates), seen between 1972 and 1974. The anatomical and angiographic study revealed 5 anatomical types, according to whether the pulmonary orifice was patent or atretic, and according to the size of cavity of the right ventricle, which may be normal or reduced (perhaps almost totally). The diagnostic clinical features and findings on angiography are recalled. The operative procedure in all 25 cases was pulmonary valvotomy carried out with a brief normothermic period of cirulatory arrest. The technique is described briefly. The results, which vary widely with the anatomical type, were as follows: out of the 25 operated cases there were 12 deaths during or immediately after surgery. The figures are none-the-less encouraging, given the grave natural history of this condition in the baby. The best results were seen in cases in which there was a right ventricular cavity of normal or at least acceptable size. The maximum postoperative follow-up period was 3 years. Most of these children have a persistant pulmonary stenosis and hypertrophic right ventricle, and require a second operation in early infancy.

[Primary bacterial aneurysm of the aorta. 4 cases].

The causal agent was a Salmonella in three cases and a Pseudomonas Aeruginosa in one case. In these four patients there was no evidence of endocardities and the causal germ was verified by the bacteriological cultures of the anevrysmal lesions and/or by the blood cultures. In one patient full recovery was obtained by surgical repair after complete bacteriologic cure.
