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…

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-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…

DEFINITY® (Perflutren Lipid Microsphere Injectable Suspension, Lantheus Medical Imaging, North Billerica, MA) received approval for clinical use by the US Food and Drug Administration (FDA) in 2001 for “opacification of the left ventricular cavity and enhancement of left ventricular border delineation in patients with technically difficult echocardiograms.”1 By 2007, it was estimated that two…

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…

Stress echocardiography is a widely used clinical technique that provides invaluable information in patients with known or suspected coronary artery disease (CAD). Common applications of stress echo include the diagnosis of reversible ischaemia, myocardial viability, and establishing the functional significance of known coronary lesions. Stress echo has been shown to have similar sensitivity and…

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…

Accurate detection of left ventricular (LV) thrombus affects clinical outcomes and therapeutic management, as thrombus provides a substrate for thromboembolic events and a rationale for anticoagulation. Relative risk (RR) for thrombus development is highest among subjects with systolic heart failure or myocardial infarction (MI), reflecting a link between impaired LV blood stasis, pro-coagulant…
