“…Myocardial contrast echocardiography (MCE) has recently emerged as a potentially useful method for studying myocardial perfusion in coronary artery disease and reperfusion after acute myocardial infarction 3–6 . Experimental studies based on animal models confirmed that MCE accurately delineated myocardium during coronary occlusion, as well as quantifying the ultimate size of an infarct 7 …”

Echocardiography is a diagnostic technique that uses ultrasound (high frequency sound) to produce an image of the heart in real time. The comprehensive echocardiographic exam uses multiple imaging formats to evaluate the heart. These include direct imaging of the heart with M‐mode, two‐dimensional, and three‐dimensional formats and direct interrogation of blood flow through cardiac chambers and across valves with pulsed Doppler, continuous wave Doppler, and color flow Doppler. Echocardiographic transducers may be placed in multiple locations on the chest wall to obtain different views of the heart and also, using specialized devices, inside the esophagus and stomach and inside the heart mounted on special catheters that allow interrogation using a miniaturized transducer. To achieve usable information the reflected ultrasound signal is intensively processed after it is detected in the transducer. Modern transducers have upward of 256 transmit and receive elements that process the ultrasound signal. The reflected ultrasound signal is manipulated in multiple selective ways to best display the wide range of cardiac anatomy and motion encountered in the exam. Similarly, several different techniques of processing are used to display and quantify Doppler analysis of blood flow. Data from the echocardiographic exam is used to quantify anatomic size and shape of cardiac chambers, diagnose changes in cardiac structure characteristics of different kinds of cardiac disease, evaluate functional performance of the heart as a pump, characterize normal and abnormal anatomy, motion, and blood flow characteristics of heart valves, and determine the presence of various other abnormalities in and around the heart such as collections of fluid, blood clots, tumors, or areas of calcification. Echocardiography is a powerful diagnostic tool that safely and noninvasively evaluates the heart.

Over the past three decades, echocardiography has become a major diagnostic tool in the arsenal of clinical cardiology for real‐time imaging of cardiac dynamics. More and more, cardiologists' decisions are based on images created from ultrasound wave reflections. From the time ultrasound imaging technology provided the first insight into a human heart, our diagnostic capabilities have increased exponentially as a result of our growing knowledge and developing technologies. One of the most intriguing developments that brought about a decade‐long combination of expectations and disappointments was the introduction of echocardiographic contrast agents. Despite repeated waves of controversy regarding the readiness of this technology for clinical use, it has overcome multiple hurdles and currently provides useful clinical information that helps cardiologists to diagnose heart disease accurately. Since the initial reports on the use of ultrasound contrast media such as agitated saline or renografin, the major advances in the field of contrast echocardiography have included (1) the development of stable perfluorocarbon‐filled microbubbles, frequently referred to as second‐generation contrast agents; and (2) the development of contrast‐targeted nonlinear imaging modes, such as harmonic imaging, pulse inversion, and power modulation, which allow consistent real‐time visualization of these agents. These contrast agents in conjunction with the new imaging technology constitute powerful tools that improve our ability to evaluate left ventricular function and myocardial perfusion, and allow differential diagnosis of thrombi and intravascular masses. In this manuscript, we briefly review some of the literature that has provided the scientific basis for the use of echocardiographic contrast agents in the context of these important variables.
