Abstract:
We present an illustrative case report of the mid-vessel left anterior descending (LAD) coronary artery spasm, which has been enhanced by straightening of the tortuous LAD segment with a guidewire ("accordion effect") thus resistant to intracoronary nitroglycerine and mimicking a coronary artery dissection. Dynamic appearance of this iatrogenic pseudo-lesion upon administration of intracoronary nitrates and recognition of these angiographic phenomena prevented from unnecessary further intervention.

Coronary Circulation
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...
