Case contributed by Dr Yune Kwong

Presentation

Known coronary artery disease.

Patient Data

Age: 60-65 years old
Gender: Male
CT

ECG-gated coronary CT angiogram

Curved MIP shows critical stenosis (C) in the proximal LAD. Further moderate-to-severe (M) stenosis in the mid-LAD. A stent (S) is also seen more distally.

Reconstructed images show sub-endocardial hypodensity (arrows), consistent with a resting perfusion defect in the LAD territory.

DSA (angiography)

Catheter angiogram.

Catheter angiography confirms critical stenosis in the proximal LAD (arrow).
