Background. This ­study was ­planned to ­show the ­effect of ret­ro­per­fu­sion and car­di­o­pul­mo­nary ­bypass on myo­car­dial hemo­dy­nam­ic recov­ery.
Methods. Eighteen ­dogs ­entered ­this ­study. After, ­left ante­ri­or descend­ing ­artery (LAD) was dis­sect­ed and occlud­ed, the ani­mals ­were divid­ed into ­three ­equal ­groups; ­Group I: ret­ro­grade cor­o­nary ­sinus per­fu­sion, ­group II: cardiopulmonary ­bypass and ret­ro­grade cor­o­nary ­sinus per­fu­sion, ­Group III: con­trol ­group, ­left ante­ri­or descend­ing ­artery occlu­sion ­only.
Results. In ­Group III, dete­ri­ora­tion of the hemo­dy­nam­ic val­ues pro­gressed par­allel ­with the ­degree of ischem­ic dam­age but in ­Group I, hemo­dy­nam­ic param­e­ters ­were bet­ter ­because of the ret­ro­grade cor­o­nary ­sinus per­fu­sion and min­i­mal­ly affect­ed by the reper­fu­sion. In ­Group II, at the end of the car­di­o­pul­mo­nary ­bypass min­i­mal myo­car­dial dam­age was ­observed.
Conclusions. There is no sta­tis­ti­cal dif­fer­ence ­between ­Group I and II if we exam­ine the ­data ­that was tak­en ­after reper­fu­sion ­although myo­car­dial per­for­mance was bet­ter in ­Group II.
