Abstract
A 64-year-old woman referred with a 4-month history of intractable chest pain. Coronary angiography was
performed and showed normal left coronary arteries. Posterior descending coronary artery was filled via distal
left circumflex artery. The right coronary artery injection showed prompt filling of the distal circumflex through
prominent collaterals. There was no evidence of proximal obstructive disease or spasm. We present a case in
which a large collateral artery was seen in angiographically normal coronary arteries.
