[Double mitral orifice. Apropos of a case]. / Double orifice mitral. A propos d'une observation.

The authors report a case of Double Mitral Orifice (DMO), existing in isolation and type 3 by the Floch Prigent classification. This rare anomaly is often associated with another congenital malformation, dominated by intra-atrio-ventricular defect. Two-dimensional echocardiography is the essential diagnostic factor. Hemodynamic consequences may be nil, but mitral insufficiency and/or stenosis may complicate this malformation. Treatment may be summarised as abstention, surgical repair or valve replacement, according to the severity of lesions.

Local thrombolysis and thromboaspiration in the treatment of acutely thrombosed arteriovenous hemodialysis fistulas.

Sixty-four thrombosed hemodialysis fistulas in 55 patients were treated by local low-dose infusion of urokinase, percutaneous angioplasty, and thromboaspiration. Lysis was initially successful in 38 cases (59%) without any negative side effects. At 1 year, 59% of these fistulas were still functional. When the procedures failed, surgery saved the vascular access in 17 cases. Local fibrinolysis combined with thromboaspiration and angioplasty provides a clinically useful means of access preservation.

[Postoperative iatrogenic coronary-ventricular fistula]. / Fistule coronaro-ventriculaire iatrogénique post-opératoire.

Acquired coronary cardiac fistulas are rare. To date, thirty cases have been published in the literature, all secondary to thoracic trauma. The right cardiac chambers were more frequently involved. A recent continuous cardiac murmur is the most constant finding. Nontreated, these lesions tend to induce coronary insufficiency and congestive heart failure. 22 of the 30 reported cases were managed surgically. We hereby report a case of postoperative coronary cardiac fistula secondary to left ventricular venting, in which the fistula involved the left ventricular cavity.

Anomalous origin of the right coronary artery from the ascending aorta.

A 47 yr-old man had an anomalous origin of the right coronary artery from the left anterior wall of the ascending aorta. This was demonstrated by aortography and by selective right coronary angiography.

[Magnetic resonance imaging in the diagnosis of pheochromocytoma]. / L'imagerie par résonance magnétique dans le diagnostic des phéochromocytomes.

The diagnosis of pheochromocytoma is biological. If ultrasound enables the visualization of certain adrenal tumours or hepatic metastasis, in fact two tests enable the topographic diagnosis, the screening of ectopic localizations and metastasis. They are IMBG scintigraphy and tomographic scanning. The place of magnetic resonance imaging is not yet specified. However, it has many advantages: absence of irradiations, good anatomic precision, meticulous screening of ectopic forms, of metastases and of adenopathies, study of the tissue characterization, good definition of the tumour relation with the vascular pedicles and the neighbouring structures.

[Diagnosis of disorders of the aorta and great vessels]. / Diagnostic des affections de l'aorte et des gros vaisseaux.

The great vessels (aorta, pulmonary arteries, carotid arteries, renal arteries, vena cava) can now be visualized by several methods, such as digital subtraction angiography, computed tomography, Doppler sonography and magnetic resonance imaging. The indications for these methods depend on the vessel studied and on the pathology investigated. The authors review the indications for each of the great vessels.

[Endocavitary fulguration in the treatment of cardiac arrhythmia]. / La fulguration endocavitaire dans le traitement des arythmies cardiaques.

Fulguration of the heart cavities seems currently to be a technique of increasing value in the treatment of untractable arrhythmias, of supraventricular junctional or ventricular origin. This study represents the evaluation of our experience with 64 patients, maximum follow-up is 54 months and the minimum follow-up is 7 months. Although the results are quite satisfactory in the fulguration of the bundle of his and in the fulguration of the arrhythmic site inducing ventricular tachycardia, these results are inferior in the Wolff-Parkinson-White syndrome in which fulguration of the coronary sinus seems contraindicated al filter (LEM type), resulting in the death of the patient. It is a true, early (1st week) migration after accurate positioning, opposite L4, and not an incident of insertion.
