Abstract

The role of coronary collateral circulation has been thoroughly studied, and myocardial perfusion imaging has been a frequently employed method. Even angiographic invisible collaterals can support some degree of tracer uptake, but the clinical role of this evaluation is still uncertain, and this remains the main issue that should be clarified.
