Contemporary approved echo contrast agents share a common approved indication of left ventricular opacification and enhancement of endocardial border delineation for the assessment of left ventricular function in patients with technically suboptimal echocardiograms (ECGs). The use of echo contrast agents with advanced imaging technologies has resulted in the conversion of many non-diagnostic ECGs…

Several advances in the field of echocardiography have led to improvements in the accuracy of stress echocardiography (SE) and further strengthened its established diagnostic and prognostic role in patients with known or suspected coronary artery disease (CAD). 1,2 In addition to its role in CAD, SE can be used to assess the severity of valvular heart disease and for detection of occult pulmonary…

Coronary artery disease (CAD) represents a tremendous financial and health burden as the leading cause of death in the US.1 Acute coronary syndrome and its subsequent manifestations, including heart failure and need for cardiac transplantation, are associated with significant morbidity and mortality. Hypertension, dyslipidemia, tobacco abuse, diabetes, chronic kidney disease, and family history…

Coronary artery disease (CAD) represents the leading cause of morbidity and mortality in western countries. Many non-invasive stress tests are currently available for detecting CAD and assessing prognosis. Non-invasive stress techniques comprise exercise electrocardiographic (ECG) stress testing and imaging techniques, namely exercise/pharmacological stress echocardiography (SEcho) and exercise…

How Far Have We Come?
Cardiac imaging using ultrasound (so-called ‘echocardiography’) was introduced more than 50 years ago. Resting echocardiographic detection of myocardial infarction was described as the reduction in regional contractile function,1 and the development of stress echocardiography in the early era was recognised after the introduction of 2D echocardiographic imaging. The initial…

Ultrasound contrast agents capable of transpulmonary passage following intravenous injection have been commercially available since the 1990s. These agents are microbubbles, which are smaller than red blood cells and persist long enough (due to reduced rate of gas diffusion) to reach the left ventricle (LV).1–3 Ultrasound contrast agent applications included LV cavity opacification, enhancement…

Contrast echocardiography (CE) is 40 years old this year. Gamiak and Shah first described the use of ultrasound (US) contrast in 1968 during the early days of M-mode echocardiography.1 In that study, US contrast was produced by inadvertently introducing air bubbles in the indocyanine green solution that was injected into the left heart during cardiac catheterisation and observing its appearance…

Contrast-enhanced ultrasound imaging (CEUS) is a non-invasive imaging modality that utilizes air-filled microspheres as blood pool agents, which act as intravascular indicators, resulting in improved accuracy and reliability in performing ultrasound images of the heart. CEUS is increasingly used throughout the US, South America, Australia, the Middle East, Europe, Japan, Canada, and Asia as a…
