Abstract

Nowadays, the classifications of coronary arterial preponderance (Schlesinger, Baroldi, Gensini) do not provide the necessary information for a good systematization of coronary arterial irrigation. Based on segmental analysis (Selvester's method) an alternative classification of the arterial distribution of the left ventricle is presented. One thousand eighty ventricle segments corresponding to 90 human hearts (age range from 4 days to 94 years) are studied, using microdissection techniques. In order to obtain segmental arterial patterns, a cluster analysis was used. The alternative classification is based on the predominance of the segments irrigated by: the anterior interventricular artery (Type I; 31% of cases), the circumflex artery (Type II; 37% of cases), or a balance between both arteries (Type III; 32% of cases). Each group can be divided into two subgroups (A and B), according to the existence or not of a balance between the territories of anterior interventricular and circumflex arteries. This classification allows as a more realistic approach to the subject of arterial dominance, given that the left ventricle always presents a predominant irrigation from the anterior interventricular, the circumflex or both arteries. © 1993 Springer-Verlag.
