Two technical maneuvers are presented to make the administration of cardioplegia feasible in the presence of moderate aortic valve incompetence. In the first maneuver, the cardioplegic solution is administered through a double-lumen balloon catheter inserted retrograde through the aortic wall and the aortic valve into the left ventricle; the inflated balloon obstructs the aortic orifice while the solution is injected through the proximal hole. In the second, after proximal anastomoses of the saphenous vein grafts are performed, the portion of the aorta from which the vein grafts rise is excluded by double cross-clamping and the cardioplegic solution is injected into this excluded segment.
