Summary

The variations of the direction of the myocardial bundles of the bridges over coronary arteries and branches were studied in relation to the direction of the vessels over which they are found. The investigation was performed on 82 hearts of individuals whose death was accidental and unrelated to cardiac disease. The hearts were obtained from cadavers of individuals of either sex and different racial groups, whose age ranged from 7 to 68 years. The angle between the direction of the musculature and of the vessels may explain why in some cases there is no change in the structure of the “pontine portion” of the wall.

Résumé

Ce travail étudie les variations de direction des fibres des ponts myocardiques et des artères coronaires et de leurs branches recouvertes par ces ponts. Les recherches ont été effectuées sur 82 coeurs de sujets décédés accidentellement et ne présentant aucune pathologie cardiaque. Ces coeurs ont été prélevés sur des sujets des deux sexes et de différents groupes raciaux dont l'âge s'échelonnait entre 7 et 68 ans. L'angle qui existe entre la direction des fibres musculaires et celle des vaisseaux peut expliquer pourquoi dans certains cas il n'y a pas de modification dans la structure de la paroi artérielle au niveau de sa “portion pontée”.
