Abstract
Methods and apparatus are provided for use in intraoperative and percutaneous procedures for supplying long-term retrograde perfusion of the myocardium via one or more conduits disposed between the left ventricle and the coronary venous vasculature. The conduits are of a selected size and number, and portions of the venous vasculature or coronary ostium are partially or completely occluded, to maintain a parameter related to the pressure attained in the venous vasculature to a value less than a predetermined value.
