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…

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…

Tissue Doppler-based measurements of myocardial strain are possible and accurate for structures that move along the ultrasound beam, but are underestimated in other directions and even impossible for angles close to 90º. To overcome these limitations, the speckle tracking technique was introduced in 2004, offering a more user-friendly workflow and better reproducibility.1 This echocardiographic…

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…

The cardiac imaging field has experienced significant improvements over the last decade due to technological advances. Cardiac computed tomography (CT), cardiac magnetic resonance imaging (MRI), nuclear cardiology, and echocardiography have all become feasible imaging modalities for physicians to evaluate in order to answer specific diagnostic questions. Each of the aforementioned modalities has…

Atherosclerosis and its thrombotic complications are the first cause of mortality and morbidity in industrialized countries. Furthermore, despite pharmacological intervention and lifestyle changes, cardiovascular disease (CVD) continues to be the principal cause of death in the US.1 Despite great advances in the understanding of the initiation and progression of atherosclerosis and its risk…

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…

Heart disease, specifically coronary artery disease (CAD), is the leading cause of death and disability among both men and women in the US. Reductions in blood supply due to narrowings of the arteries that supply the heart muscle with oxygen and nutrients (coronary arteries) result in chest pain and shortness of breath and may lead to permanent scarring of the heart muscle, as in the setting of a…
