The “Lightbulb” Sign [PDF]

JACC: Case Reports, 2023
We report a case of fulminant COVID-19–related myocarditis requiring venoarterial extracorporeal membrane oxygenation where the use of an ultrasound-enhancing agent demonstrated a previously undescribed echocardiographic finding, the “lightbulb” sign ...

Validation of administrative claims to identify ultrasound enhancing agent use [PDF]

Echo Research and Practice
Background Ultrasound enhancing agents (UEAs) are an invaluable adjunct to stress and transthoracic echocardiography (STE) to improve left ventricular visualization. Despite multiple single center studies evaluating UEA use, investigation into the rates,

Identification of Need for Ultrasound Enhancing Agent Study (the IN-USE Study) [PDF]

Journal of the American Society of Echocardiography, 2020
Ultrasound enhancing agents (UEAs) are routinely used to improve transthoracic echocardiographic (TTE) image quality, yet anticipation of UEA need is a barrier to their use.Structured report data from 171,509 consecutive TTE studies in 97,515 patients who underwent TTE imaging from January 26, 2000, to September 20, 2018, were analyzed.

Selective Enhancement of Swine Myocardium with a Novel Ultrasound Enhancing Agent During Transthoracic Echocardiography [PDF]

Journal of Cardiovascular Translational Research, 2022
Ultrasound enhancing agents are approved to delineate the endocardial border and opacify the left ventricle cavity (LVC). We present a nested phase change agent (NPCA) designed to enable selective myocardial enhancement without enhancing the LVC by employing a dual-activation mechanism dependent on sufficient ultrasound intensity and the ...

An imaging artifact unmasked by contrast‐enhanced transesophageal echocardiography

Clinical Case Reports, 2023
Key Clinical Message Performing transesophageal imaging of the left atrial appendage is key before cardioversion for atrial fibrillation. Ultrasound artifacts may induce misinterpretation and decrease in confidence for thrombus exclusion.

Improved efficiency and diagnostic utility of inpatient transthoracic echocardiography following implementation of a sonographer-initiated perflutren-based contrast administration protocol

Cardiovascular Ultrasound, 2020
Background Up to 20% of resting echocardiograms obtained are suboptimal leading to further downstream testing and delays in diagnosis. Contrast enhanced echocardiography is well established and endorsed for use by the American Society of Echocardiography
