Key result
Intracoronary administration of 200 mcg nitroglycerin completely resolved catheter-induced multiple non-proximal coronary spasms that initially simulated fixed atherosclerotic stenosis.
Population

Intracoronary nitroglycerin may distinguish catheter spasm from fixed stenosis; this single case leaves open routine applicability and diagnostic impact.

Catheter-induced vasospasm can occur at multiple non-proximal sites and simulate fixed coronary stenosis, which can be resolved with intracoronary nitroglycerin to avoid misinterpretation.
Esenboğa et al. (2020) conducted a case report in Myocardial Infarction / Catheter-induced vasospasm (n=1). Intracoronary nitroglycerin was evaluated on Resolution of coronary spasm. Intracoronary administration of 200 mcg nitroglycerin completely resolved catheter-induced multiple non-proximal coronary spasms that initially simulated fixed atherosclerotic stenosis.
