End-capillary loops in the heart: an explanation for discrete myocardial infarctions without border zones.

E M Okun, S M Factor, E S Kirk.   

Abstract

Separate perfusions of canine coronary arteries with colored silicone-rubber compound reveal that in the region where two microcirculations abut, capillaries derived from individual large vessels are discrete, with no interconnections. Terminal homologous capillaries from loops rather than anastomosing with heterologous capillaries. This anatomic arrangement may account for discrete myocardial infarctions without ischemic border zones.
