Objective -To test the feasibility, safety and accuracy of the adenosine protocol in the study of myocardial perfusion with microbubbles contrast echocardiography. Methods -

ObjectiveTo compare myocardial contrast echocardiography (MCE) using PESDA and adenosine in bolus (ADN) with myocardial nuclear scintigraphy (NS) ResultsIn 106/125 pts, . . For the LAD territory, concordance was 87.2%; for the RCA, 93.6%; and for the CX, 92.8% (P < 0.001). ConclusionAn excellent concordance exists between MCE and NS in assessing pts for coronary artery disease; therefore, MCE may represent a good alternative for assessing myocardial perfusion.
