[Ascending aortic aneurysm with mucoid infiltration of the media and aortic leaflets. Pathogenic hypotheses- surgical consequences].

The theoretical and practical problems posed by aneurysms of the ascending aorta with mucoid infiltration of the Media and the aortic leaflets are discussed with reference to two suggestive cases. These histological changes are not specific for Marfan's syndrome, the relation with which is very inconstant. Incomplete replacement of the affected tissues risks a recurrence which is especially serious when the sinus of Valsalva is involved.

[Anatomic aspects of Prinzmetal's angina: apropos of an anatomo-clinical case].

Report of one case of Prinzmetal variant of angina pectoris with a typical clinical and electrocardiographic picture in a man aged 87. Severe arrhythmias resulted in death of the patient. On autopsy a moderate narrowing of the anterior interventricular artery was demonstrated.
