Echocardiography has now reached its maturity and plays a key role in the clinical assessment of cardiac function however its ability to assess myocardial perfusion remains a clinical challenge myocardial contrast echocardiography is a technique that uses microbubbles. Abstract contrast echocardiography is widely used in cardiology it is applied to improve image quality reader confidence and reproducibility both for assessing left ventricular lv structure and function at rest and for assessing global and regional function in stress echocardiography. Clinical protocols which assist sonographers and medical staff in selecting patients likely to benefit from the addition of echo contrast agents allowed the introduction of contrast echocardiography into this busy laboratory without undue impact on workflow. Focus on learning objectives understand the evidence and clinical practice for the use of contrast enhancement in echocardiography according to the updated eacvi recommendations. After fda approval of the new generation contrast agent optison mallinckrodt medical st louis mo january 1998 the use of contrast in echocardiograhy has become an invaluable tool a review of 100 patients revealed contrast to be useful for endocardial border definition and wall segment analysis enhancement of pulsed doppler and chamber opacification for the detection of thrombi
