Retrograde coronary sinus perfusion in aortic valve replacement with beating heart in five cases
Abstract：Continuous retrograde coronary sinus perfusion（CRCSP） withbeating heart was performed in three patients of aortic stenosis and insufficiency undergoing aortic valve replacement and two patients of aortic stenosis and insufficiency concurrent mitral stenosis and insufficiency undergoing aortic valve combined with mitral valve replacement.During operation the heart was perfused with oxygened blood.To determine the content of creatine phosphokinse（CPK）and lactic dehydrogonase（LDH）before and after operation.After operation，all patients had a good recovery and did not develope any serious arrhythmia or low-output syndrome or embolism of gas embolus.Dopamine was used postoperatively 0～5μg／（kg.min）.The difference content of CPK and the difference content of LDH have no significance bofore and after operation.CRCSP with beating heart under extracorporeal circulation with low dose temperature is a simpl，safe and physiological myocardial protection method.
