Abstract:
Objective To study the effect of heart function and histopathology after coronary vein bypass grafting.Methods 16 pigs were divided into experimental group and control group.Following 16 pig models of chronic myocardial isehemia of left ventri- cle were established,the left internal mammary artery (LIMA)-great cardiac vein (GCV) anastomasis in 8 pigs were completed 4 week later.After GCV occlusion at proximal,retrograde coronary venous perfusion was afforded.At 8 week,coronary angiography,echo- cardiography and myocardial radioisotope scanning were performed.After harvesting these hearts,histopathologic examination and electron microscope were undertaken.Results All anastomotic vessels of experimental pigs were smooth.LVEF in experimental group was significant higher than that in control group (P
