In 104 hearts of infants and children, who died from non-vascular diseases, and whose ages ranged up to 10 years after birth, narrowing of the aortic isthmus, i.e. an internal diameter of 80% or less of that of the descending aorta, was found in 26 cases (24%). The remaining cases showed a lesser degree or no narrowing of the aortic isthmus. Among the 38(More)
In a post mortem material of 17 cases of transposition of the great arteries (TGA) from patients with an age range from birth to two years and ten months after birth, the internal calibres of the great arteries and the ostia of the heart proved to be the same as in normal hearts. Furthermore, the media of the ascending aorta and pulmonary trunk showed no(More)
La dégénérescence des plaques motrices, causée par voie cérébrospinale et neurovégétative, a été étudiée entre autres au moyen de la technique acétylcholinestérasique et celle de Champy-Coujard chez le rat et le lapin. En outre, des biopsies musculaires chez les patients neurologiques ont été examinées. Jusqu'ici nous n'avons pas réussi à trouver chez ces(More)
In an autopsy material of 29 cases of the hypoplastic left heart syndrome coronary fibroelastosis was found in 1 case, endocardial fibroelastosis in 8 eases. Figures for 10 cases of the hypoplastic right heart syndrome were 6 cases of coronary fibroelastosis and 1 ease of endocardial fibroelastosis. Age ranged from stillborn up to 11 1/2 months. Coronary(More)
After repair of coarctation of the aorta using the technique of resection and end-to-end anastomosis, the internal diameters of the aortic isthmus and descending aorta often fail to increase. Better results seem possible with aortoplasty using the left subclavian flap technique. In order to clarify this matter, we investigated the structure of the left(More)
