Methods of myocardial protection from ischemic and reperfusion injuries in various operations on the open heart were compared. The study demonstrated the advantages of combined antegrade-retrograde delivery of cardioplegic solution during ischemia in aortocoronary shunting and correction of valvular defects. The method of myocardial protection from reperfusion injury by perfusing the heart with blood solution of a special composition before removing the clamp from the aorta (controlled reperfusion) proved to be effective, which was confirmed by clinical and biochemical data presented in this paper. Hence, our findings confirmed that the optimal protection of the myocardium can be attained by combined cold crystalloid cardioplegia together with controlled reperfusion of the myocardium.

D015425 Myocardial Reperfusion Generally, restoration of blood supply to heart tissue which is ischemic due to decrease in normal blood supply. The decrease may result from any source including atherosclerotic obstruction, narrowing of the artery, or surgical clamping. Reperfusion can be induced to treat ischemia. Methods include chemical dissolution of an occluding thrombus, administration of vasodilator drugs, angioplasty, catheterization, and artery bypass graft surgery. However, it is thought that reperfusion can itself further damage the ischemic tissue, causing MYOCARDIAL REPERFUSION INJURY.

D015428 Myocardial Reperfusion Injury Damage to the MYOCARDIUM resulting from MYOCARDIAL REPERFUSION (restoration of blood flow to ischemic areas of the HEART.) Reperfusion takes place when there is spontaneous thrombolysis, THROMBOLYTIC THERAPY, collateral flow from other coronary vascular beds, or reversal of vasospasm.
