Figure 1 Image of four-chamber cross-section myocardial perfusion angiography.
A there was delayed perfusion at the apex of ventricular septum before load (end of diastole of 5 cardiac cycles after ”Flash”, arrow). B the delayed myocardial perfusion areas were reduced at peak period (end of diastole of 2 cardiac cycles after ”Flash”, arrow) ,this was ” reverse reperfusion” .C the delayed areas of myocardial perfusion were significantly increased during recovery period.
