Associated with preserved LV wall motion in obstructed arteries; leaves open whether collateral enhancement improves outcomes in prospective trials.
Does good coronary collateral circulation preserve left ventricular wall motion in patients with total or subtotal coronary obstruction?
Good coronary collateral circulation is associated with preserved left ventricular wall motion in areas with severe coronary obstruction.
