: A 54-year-old woman with a history of stage IV nonsmall-cell lung cancer, on treatment with chemiotherapy was hospitalized for acute coronary syndrome. Coronary angiography showed a tight stenosis of ostial left main coronary artery (LMCA) probably caused by external compression. Computed tomography scan confirmed LMCA compression and entrapment between a neoplastic mass and the root of the aorta, with vessel collapsing during diastole but patency and narrowing in systole. A drug-eluting stent was then successfully implanted at LMCA ostium without further episodes of angina.
