In this study, the use of a constrictive mesh for vein graft was evaluated. Fourteen sheep were subjected to a 5 cm resection of the carotid artery. Six sheep (Group A) received a(More)

A patent foramen ovale (PFO) was looked for in 500 consecutive adult autopsy studies (265 men, 235 women) in which death was due to acquired cardiovascular pathology (mainly coronary artery disease); this condition was demonstrated in 73 cases (42 men, 31 women); 14.6%. A PFO forms a short inter-atrial communication (average length 5 mm) directed anteriorly(More)

Intracardiac ectopic thyroid tissue was removed in a 51 years old woman, after echography has discovered a tumor in the right ventricle. There was a normal thyroid gland in the neck and thyroid function tests were normal. Intra-cardiac ectopic thyroid tissue is very rare; it is due to an abnormality of embryological development, when thyroid anlage is in(More)
In an anatomical study of 187 patients who had died from various heart disorders, the anterior descending artery (ADA) had an intra-mural course in 33 cases (17.65 p. 100). This abnormal course had had no correlation with the sex of the patients, the nature of the disease, length of the trunk of the left coronary artery, and to the relative sizes of the(More)
