Summary
Ninety human hearts obtained from autopsies were used. The methods applied were post-mortem angiography, dissection and the construction of an arterial map by segments, according to the classification of Selvester et al. It was shown that the arteries which have the greatest extension are the anterior interventricular and circumflex aa., while irrigation by the right coronary artery is only moderate, except in the segments of the inferior wall. Differences in the perfusion territories of the main coronary arteries and between the patterns of arterial irrigation of the left ventricle (segmental pattern and grouped pattern) were found. Finally, we define risk groups on the basis of the proportion of the ventricular mass irrigated by each artery, which are of practical interest from the clinical, prognostic and therapeutic points of view.
Résumé
90 coeurs humains issus d'autopsies ont été utilisés. Les méthodes utilisées furent l'angiographie post-mortem, la dissection et la cartographie artérielle par segments, selon la classification de Selvester et al. De l'ensemble de la série, on peut conclure que les artères qui ont la plus grande extension sont l'a. interventriculaire antérieure et l'a. circonflexe, tandis qu'elle est modérée pour l'a. coronaire droite, sauf dans les segments de la paroi inférieure. Des différences ont été trouvées dans les territoires de perfusion des artères coronaires principales, entre les types d'irrigation artérielle du ventricule gauche (type segmentaire et type groupé). Finalement, nous définissons des groupes à risques sur la base de la proportion de masse ventriculaire irriguée par chaque artère, ce qui pourrait être d'un intérêt pratique du point de vue clinique, pronostique et thérapeutique.
