[Congenital "cardio-esophageal" syndromes. Congenital cardiopathies and multiple abnormalities syndromes in the child with esophageal abnormalities].

A case of esophageal stenosis and tracheo-esophageal fistula associated with dextrocardia due to dextrorotation, ventricular septal defect and complete double arotic arch is reported. In 116 cases of esophageal atresia and tracheo-esophageal fistula 9 had an associated cardiac malformation (4 right-sided aortic arch and 4 ventricular septal defects). The possible individualization of multiple abnormality syndromes in which these two types of malformations are associated with others such as vertebral arch defects, limb anomalies, imperforate anus, etc. is discussed. These are so-called "Vater" or "Vactel" syndromes.

[The exercise test in congenital aortic stenosis].

Exercise tests can be carried out without risk in a child or young adult with asymptomatic congenital aortic stenosis. In such a case, the ECG at rest gives only a very poor indication of the severity of the stenosis, which often becomes worse with age. The only sinister findings is that of repolarisation defects, which are almost always absent at rest. Exercise, by causing an imbalance between myocardial oxygen consumption and oxygen transport, will cause "ischaemic" signs to appear on the ECG. At the same time, the absence of compensation of pressure is a very important sign of poor tolerance; the test can usefully be concluded by using a floating catheter to measure the pulmonary capillary pressure. The correlation between a positive test and the stenotic pressure gradient, measured on catheterisation at rest, is good; but "negative" tests may be found in certain cases with a tight stenosis, especially if maximal rate could not be reached. In cases of stenoses which were initially mild or moderate, this test is very useful as a follow-up procedure, as such stenoses may become worse with age and require surgical correction. It is also useful for assessing the results of surgery, and of rehabilitation.

Idiopathic dilatation of the right atrium revealed in childhood by dysrhythmias.

A 7-year-old male presented with apparently banal but repetitive episodes of paroxysmal supraventricular tachycardia, along with other manifestations of atrial hyperexcitability. Isolated dilatation of the right atrium was discovered. This disorder is usually latent or benign, but sometimes it is serious because of conduction defects. Lack of relevant studies means the basis of the disorder is not understood.

Angiocardiography in congenital subvalvular aortic stenosis: prognosis and operative indications.

Twenty-three patients with congenital subvalvular aortic stenosis are reviewed. The importance of classifying this stenosis into four types based on angiocardiographic findings is stressed, as are the indications for left heart catheterization during the preoperative and postoperative course of the disease. The type of congenital subvalvular aortic stenosis should be an important consideration during the discussion of operative indications in both asymptomatic and symptomatic patients.

[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.

[Atypical pulmonary stenosis in certain polymalformative syndromes. Prevalence of associated hypertrophique myocardiopathy].

Certain pulmonary stenoses differ markedly from the usual types of isolated valvular stenosis in their clinical features (maximal murmur situated lower down), their radiological signs (absence of a prominent median arc), the electrocardiograph (atypical electrical axis), the haemodynamic findings (usually a poor gradient), and especially the angiocardiography (valvular dysplasia, lack of a post-stenotic dilatation). They are encountered especially in the multiple malformations, as shown by this series of 23 cases comprising the syndrome of Noonan (9), of Gorlin or 'leopard' (7), of Watson or 'café-au-lait spots' (3), or those defying classification, but always having a disorder of facial structure and mental deficiency, sometimes with deafness (4). The frequent finding of a gradually progressive hypertrophic cardiomyopathy is a feature of these syndromes, and usually accounts for the abnormal ECG findings. It leads to a discussion of the pathogenesis, and of the place of these syndromes in a wider context, alongside the phacomatoses and the hereditary forms of neuromuscular degeneration.

[Solitary azygos prolongation (author's transl)].

Azygos prolongation of the inferior vena cava is a congenital abnormality which is normally associated with a congenital cardiac lesion, abnormalities of the inferior caval system and, in some instances, abdominal heterotaxia. The authors report here a case which is exceptional in the sense that the azygos prolongation was isolated. Further radiological studies are essential in order to make the diagnosis following the discovery of a right-sided laterotracheal opacity on a plain chest film. Only five other cases were found in the literature.

Case report of congenital tricuspid insufficiency.

This is a report of a 16 years old male with moderate mitral disease, probably rheumatic, and with severe tricuspid insufficiency which at surgery appeared to be a congenital malformation of the tricuspid valve (absence of the anterior leaflet). A tricuspid heterograft was successfully inserted. The symptoms of congenital tricuspid insufficiency are discussed and this affection is differentiated from other causes of tricuspid insufficiency.
