WebbThis condition is referred to as “no-reflow phenomenon.” [1,2] According to Kloner et al,[3] no-reflow is defined as suboptimal myocardial reperfusion through a part of coronary circulation without angiographic evidence of mechanical vessel obstruction. Mechanism and Pathogenesis of No-Reflow This unique phenomenon is still poorly understood.
