BACKGROUND: Real time myocardial contrast echocardiography (RTMCE) is an emerging imaging modality for assessing myocardial perfusion that allows for noninvasive quantification of regional @entity296 ( @entity296 ). AIM: We sought to assess the value of qualitative analysis of myocardial perfusion and quantitative assessment of @entity296 ( @entity296 ) by RTMCE for predicting regional function recovery in @entity1 with @entity741 who underwent coronary artery bypass grafting (CABG). METHODS: Twenty-four @entity1 with @entity301 and @entity1002 (ejection fraction <45%) underwent RTMCE before and 3 months after CABG. RTMCE was performed using continuous intravenous infusion of commercially available contrast agent with low mechanical index power modulation imaging. Viability was defined by qualitative assessment of myocardial perfusion as homogenous opacification at rest in >= 2 segments of anterior or >= 1 segment of posterior territory. Viability by quantitative assessment of @entity296 was determined by receiver-operating characteristics curve analysis. RESULTS: Regional function recovery was observed in 74% of territories considered viable by qualitative analysis of myocardial perfusion and 40% of nonviable (P = 0.03). Sensitivity, specificity, positive and negative predictive values of qualitative RTMCE for detecting regional function recovery were 74%, 60%, 77%, and 56%, respectively. Cutoff value of @entity296 for predicting regional function recovery was 1.76 (AUC = 0.77; 95% CI = 0.62-0.92). @entity296 obtained by RTMCE had sensitivity of 91%, specificity of 50%, positive predictive value of 75%, and negative predictive value of 78%. CONCLUSION: Qualitative and quantitative RTMCE provide good accuracy for predicting regional function recovery after CABG. Determination of @entity296 increases the sensitivity for detecting hibernating @entity1562 .
