Further Evidence for a Critical Vessel Caliber in Experimental Coronary Shock
New experiments confirm previous observations that production of protracted coronary shock in the closed-chest dog following microsphere embolization is a critical function of the embolus size. The vessels occluded by the critical emboli have been located by a plastic coronary injection-tissue corrosion technic, and a definite relationship has been demonstrated between vessel caliber and anatomic type, in a dog heart, for the gradient from epicardium through endocardium.
