[Assessment of the branches of the pulmonary artery by 2-dimensional echocardiography].

Sixty three cases of Fallot's tetralogy aged from 1 month to 30 years old, were studied by 2D echocardiography to evaluate the diameter of the pulmonary arteries and to detect stenosis of the main pulmonary arteries. The right pulmonary artery was visualised clearly enough to be measured in all 63 cases whereas the left pulmonary artery could only be adequately recorded in 58/63 cases. The junction of the two pulmonary arteries was confirmed by 2D echo in 61/63 cases; in two cases, the left pulmonary artery was not connected (2/63), confirmed at angiography and surgery. Six stenoses of the pulmonary arteries, confirmed surgically (6/7), were detected by 2D echo but there were also 3 false positive results. The pulmonary arteries were measured from suprasternal views; the values obtained ranged from 3 to 15 mm. There was a good correlation with the angiographic measurements (R = 0.81 for the right pulmonary, and R = 0.82 for the left pulmonary arteries). Good correlations were also observed between the peroperative and 2D echo measurements (R = 0.84 for the right pulmonary; R = 0.77 for the left pulmonary artery). 2D echocardiography is a non-invasive reliable technique for visualising the pulmonary arteries and their origin, for measuring the calibre of these vessels and for detecting severe proximal pulmonary artery stenosis.

[Diagnosis of a complete atrioventricular canal with infundibular pulmonary stenosis and left superior vena cava by 2-dimensional contrast echocardiography. Apropos of a surgically treated case].

The case of an eight year old child with complete atrioventricular canal, pulmonary infundibular stenosis and persistent left superior vena cava draining into the coronary sinus is reported. Two-dimensional echocardiography with injection of contrast in a left arm vein gave a precise and complete diagnosis of the malformations before catheterisation and angiography. The complete atrioventricular canal was demonstrated by apical four-chamber views. The pulmonary infundibular stenosis was visualised by a short axis subcostal view. Contrast echocardiography in the apical four-chamber view showed a right-to-left shunt at atrial level at the site of the ostium primum and a right-to-left shunt at ventricular level just below the hemivalve. The left superior vena cava was detected by a short axis suprasternal view which visualised its vertical trajectory as far as the coronary sinus. The lesions were confirmed at surgery, and a complete repair was performed.

[One stage repair of VSD in infants (author's transl)].

Concerning their experience between February 1973 and May 1979 about 258 infants less than 12 Kg operated up for large VSD, the authors studies the 27 deaths. Their is not statistical difference between patients under 6 Kg of weight (128 cases, 15 deaths) and patients over 6 Kg of weight (130 cases, 11 deaths). The procedure is performed under hypothermia and circulatory arrest under 5 Kg and moderate hypothermia with cardioplegic myocardial protection in other cases. The causes of deaths have been: --either post-op. complications (post-operative bleeding, catheter complication, mediastinitis), --or pre-operative error (Swiss cheese VSD, single ventricle). The indications for pulmonary artery banding remain multiples VSD, and VSD associated with other visceral malformations.

[Cor triatriatum associated with a ventricular septal defect in infancy. 2 cases treated surgically].

Although rare, the diagnosis of cor triatriatum in its classical form is usually made pre-operatively. The association with a large ventricular septal defect, as in the two cases reported here, masks the clinical and haemodynamic signs. In one case it was the echocardiogram and cineangiography which led to pre-operative diagnosis. The surgical correction of the two lesions was done successfully in one stage. In our second case, lack of recognition of the cor triatriatum led to the death of the patient in a low output state, following closure of the ventricular septal defect.

[A new anatomo-clinical entity? The left superior vena cava obstructing the interior of the left atrium in association with a left-right shunt. Apropos of 2 cases].

The association of a left-right shunt with obstruction to the pulmonary venous return must not be ignored. Failure to recognise this may be fatal post-operatively. We have described here what we believe to be a new cause of supra-mitral obstruction: an abnormal left superior vena cava. The echocardiogram was essential in the diagnosis, and allowed us to establish, after surgical correction, that all abnormalities of the left auricle had disappeared.

[Unexpected findings during surgery for interventricular communication and for banding of the pulmonary artery in the infant and child].

While the authors recognise the difficulty of obtaining a complete picture of the lesion in certain types of ventricular shunt with pulmonary hypertension, they emphasise the importance of a precise diagnosis, which may modify the medical treatment and the decision to operate. Conditions may nevertheless be found by surprise at operation, and lead to a modification of the planned action.

[Intraspinal venous hypertension due to multiple anomalies in the caval system. A major cause of myelopathies].

Increased venous intraspinal pressure is described as a venous system disease, resulting in numerous unexplained paraplegias and tetraplegias. The chronic venous stasis in the intraspinal plexuses, into which the circulation of the spinal cord is drained, is due to the association of multiple abnormalities (stenoses, compressions, thromboses) on the major pathways of the caval and azygos system. The abnormalities, most of which are not known, are demonstrated by a special procedure, the cavo-spinal phlebography, and some of them are subjected to surgery.

[Cavo-spinal phlebography in myelopathies of venous origin. Application of the method in 115 cases].

The intraspinal venous stasis, described by ABOULKER as the cause of numerous myelopathies, is due to the addition of multiple venous abnormalities, demonstrated by cavospinal phlebography. The venae cavae and their major affluents and the prespinal system (lumbar and ascending lumbar veins, azygos, hemi-azygos, right superior intercostal and vertebral veins) are explored by catheterization. Cavo-spinal phlebography reveals multiple obstacles and the resulting stasis in the intraspinal plexus.

[Cavo-spinal phlebography in myelopathies. Stenoses of internal jugular and azygos veins, venous compressions and thromboses].

Increased intraspinal venous pressure, resulting according to ABOULKER in numerous spastic paraplegias and quadriplegias is due to multiple venous abnormalities demonstrated by cavo-spinal phlebography. The most frequent are stenoses of the internal jugular veins, the left renal, the left iliac veins, the azygos veins and compressions of the innominate venous trunks. These abnormalities cause a permanent stasis in the intraspinal plexuses through excessive supply or insufficient drainage. Out of 80 patients, 60 per cent had at least 2 abnormalities, 38 per cent at least 3 abnormalities.

[Myocardial bridge compressing the anterior inter-ventricular artery. Apropos of a successfully operated case].

Report of the case of a 26-year-old male patient, presenting with left-sided thoracic pains combined with electrocardiographic changes. Coronary arteriography demonstrated the presence, during systole, of a long, semi-localized stenosis of the anterior interventricular artery. Operation consisted only in the section of the myocardial bridge enclosing the artery on 4 cm. The clinical and coronary arteriographic result was perfect. No report of a similar case could be found in the literature.
