  • Title: Role of the coronary collateral circulation in the preservation of left ventricular function.
    Author: Hecht HS, Aroesty JM, Morkin E, LaRala PJ, Paulin S.
    Journal: Radiology; 1975 Feb; 114(2):305-13. PubMed ID: 1110994.
    Abstract:
    An angiographic assessment of the coronary arteries, the presence and quality of arterial collateralization and segmental left ventricular (LV) wall motion indicated that (a) in the presence of total or subtotal obstruction of a coronary artery, there was a significantly higher incidence of normal motion (p less than 0.001) if the segment of LV wall was supplied by good rather than poor collaterals, and (b) normal wall motion with good arterial collateralization was not associated with abnormal Q waves. It is concluded that a positive correlation exists between the quality of collateral filling and the preservation of LV wall motion in the area supplied.
