Myocardial staining is a complication of coronary angiography or intervention procedures
and consists of extravasations of contrast material into the myocardium. The powerful
injection of contrast (myocardial staining) is caused by the improper positioning
of the angiography or guiding catheter and can lead to refractory ventricular tachyarrhythmias
and occasionally cardiac death. It results in small puffs of dye extravasating into
pericoronary space (epicardial or myocardial).We presented an interesting image of
a massive myocardial staining and dense coronary and thebesian venous opacification
during complicated right coronary angiography. This case illustrates the value of
careful manipulation and positioning of the coronary catheter during coronary angiogram.
