<C. E. Nerantzis> is an author of anatomical research on <coronary arteries> and their distribution in the human <heart>. The 1996 primary paper <Functional dominance of the right coronary artery: incidence in the human heart by C. E. Nerantzis and others> lists the author with the Pathology Department, University of Athens. Its byline establishes the initials used here; it does not by itself establish a fuller personal name.<Functional dominance of the right coronary artery: incidence in the human heart by C. E. Nerantzis and others>[Primary byline, affiliation and abstract]{ref}
Nerantzis and colleagues studied 200 human hearts after injection of radiopaque material, combining direct observation with <X-ray> analysis. They classified 178 as right dominant because the <right coronary artery> gave rise to the <posterior interventricular artery>. Within those 178, they distinguished 19 specimens with both a large posterior branch and a large continuation beyond the crux. The mapped <right coronary artery> in this subgroup supplied the <right ventricle> and nearly half the <left ventricle>.<Functional dominance of the right coronary artery: incidence in the human heart by C. E. Nerantzis and others>[Abstract, injected-heart methods and right-dominant subgroup]{ref}
The nested counts show why a classification and a detailed territory map are different observations: $178/200=89\%$ of this collection met the usual right-dominance criterion, but the described extended subgroup was $19/178\approx10.7\%$ of those right-dominant hearts. These sample fractions do not automatically estimate every population. The work illustrates how <coronary dominance> summarizes a branch origin while leaving additional variation in arterial extent.
Radiopaque filling makes the vessel paths visible; it does not directly measure living blood flow under exercise or after an obstruction. The anatomical observation motivates questions about which <myocardium> a proximal lesion could affect, while physiological flow and clinical outcome require additional evidence.
