CTICasesCoronary artery spasm mimicking high-grade stenosis on CTA
Imaging findings
Coronary CTA in a 40-year-old male shows a high-grade soft plaque stenosis in the mid right coronary artery. Catheter angiogram demonstrated normal coronary arteries without stenosis.
Key takeaways
Coronary artery spasm or motion artifact can closely simulate high-grade organic stenosis on coronary CTA. Catheterization or functional assessment is needed to differentiate the two.
