- W2350508749 abstract "Objective To explore the myocardium perfusion improvement after percutaneous coronary intervention (PCI) by selective myocardium contrast echocardiography (MCE) and myocardium blush grade (MBG) and compare the two different methods in assessing the tissue perfusion after PCI. Methods MBG and intracorony MCE were performed before and after PCI in 24 patients with successful PCI (TIMI III flow achieved in epicardial artery). Both left ventricle ejection fractions (LVEF) as well as peak systolic velocity of the ischemic segments were measured before and 5 days after PCI with 2D echocardiography and tissue Doppler imaging (TDI). Results Myocardium perfusion improved significantly after PCI were demonstrated by MCE and MBG. LVEF and segmental peak systolic velocity were also significantly improved. MCE (r=0.77, P0.001) better correlated with improvement in LVEF 5 days after PCI than MBG (r=0.14, P0.05). ROC result revealed that segmental perfusion evaluated by MCE after PCI could predict the segmental peak systolic velocity (sensitivity:82%,specificity: 80%,P0.001). Conclusion Both MCE and MBG can reveal the perfusion status of myocardium. Intracoronary MCE can accurately quantity myocardium perfusion and predict short-term regional wall systolic function simultaneously. Intracoronary MCE has better clinical application value compared with MBG." @default.
