[The selective induction of a spasm with ergonovine in a normal coronary artery in the presence of contralateral stenosis].
We present a patient with circumflex artery stenosis and recent unstable angina. Selective ergonovine administration on angiographically normal right coronary artery evidenced that at least some of the anginal crisis could be due to spasms of it. We comment the usefulness of the ergonovine intracoronary test in the presence of fixed obstructive lesions.
