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 pseudolesion upon administration of intracoronary nitrates and recognition of these angiographic phenomena prevented from unnecessary further intervention.
