  1. Findings of complete visualisation of coronary artery segments with antegrade flow or coronary segments found with retrograde flow (n = 111). LM = left main coronary artery, pLAD = proximal segment of left anterior descending artery, mLAD = middle segment of left anterior descending artery, dLAD = distal segment of left anterior descending artery, pCx = proximal segment of circumflex coronary artery, mCx = middle segment of circumflex coronary artery, dCx = distal segment of circumflex coronary artery, pRCA = proximal segment of right coronary artery, mRCA = middle segment of right coronary artery, PDA = posterior descending artery
