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.

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.

[Toxins of Byssochlamys nivea Westling. I. Preliminary study of toxicity in sheep].

The acute intoxication in 4 sheep, due to an extract from a Byssochlamys nivea culture containing patulin is attained by administering per os with a syringe or with an esophagal tube doses of patulin varying from 15 to 50 mg per kg of bodyweight. A dose of 20 mg/kg, given with a syringe, brought on the death of a sheep within 5 hours following the administration, while a dose of 50 mg/kg given by an esophagal tube, only led to some temporary and slight problems. Intoxication brings on such symptoms such as nasal discharge, the stoppage of ruminating, a painful sensitivity in the retro-sternal area, weight loss, and prolonged loss of appetite. With an autopsy, a sero-fibrinous peritoneal exsudate and considerable hemorrhaging in the abomasum can be found. Anatomo-pathological examinations pinpoint lesions in the liver and kidneys. Biochemical examinations revealed hemoconcentration followed by anemia, and a considerable drop in serum proteins. The urea level increases 24 hours after and attains a notable maximum at the 30th hour (50 to 200 per cent). During these acute intoxications, no disorder whatsoever in the nervous system was observed.

Congenital localized stenosis of the pulmonary veins.

One case of localized stenosis of the extrapulmonary portion of pulmonary veins is reported in a 3 years old child. The chest X-Ray showed a rounded and pulsatile opacification over the right hilum and on angiocardiography the right superior pulmonary vein looked very dilated. 20 other cases of segmental stenoses of pulmonary veins were collected from the literature.

[Radiological study of congenital mono and bicuspid aortic valves (author's transl)].

Bicuspid aortic valves are much more common than monocuspid valves and diagnosed by A. P. aortography and, above all, lateral views. One may distinguish the true bicuspid valves which include two Valsalva sinuses, often asymmetrical, and bicuspid valves whith a supplementary raphe, the commonest type, in which on angiography, one may distinguish three Valsalva sinuses, one of which is larger than the two others. These cases of bicuspid aortic valve may be associated with other malformations of the aorta or may occur alone. In the latter case, the main risks are aortic valvular stenosis or aortic incompetence.
