Collateral presence and extent do not predict myocardial viability and ischemia in chronic total occlusions: A stress-CMR study

Well-developed collaterals are assumed as a marker of viability and ischemia in chronic total occlusions (CTO). We aim to correlate viability and ischemia with collateral presence and extent in CTO patients by cardiac magnetic resonance (CMR).
