ABSTRACT
Profound reduction of anterograde coronary flow with concomitant ischemia is seen occasionally during percutaneous coronary intervention despite technically successful procedure. We found interesting coronary flow pattern in a patient with acute myocardial infarction, showing angiographic no reflow phenomenon after direct PTCA. The coronary blood flow pattern of the angiographic no-reflow phenomenon in this case was characterized by minimal systolic flow and sharp deceleration of diastolic flow. Coronary flow reserve calculated by the ratio of adenosine induced maximal hyperemic velocity and basal velocity was reduced. The Dopplertipped guide wire was useful for observation of phasic coronary flow pattern of angiographic no-reflow phenomenon.
