Echocardiography strain imaging at ASE. #ASE2020

August 20, 2020 — DAIC – Diagnostic and Interventional Cardiology

All ASE 2020 abstracts can be viewed at:

More than 350 posters featuring cutting edge research on the advances in cardiovascular ultrasound were presented during the American Society of Echocardiography (ASE) 2020 annual meeting, Aug. 8-10. A special group of investigators were selected as the ASE Foundation’s Top 20.

These early career abstract presenters were selected by the Scientific Sessions Program Committee abstract chairs based on the scientific merit of their research projects and were awarded complimentary registration to the ASE 2020 Virtual Experience from the Foundation.

“The abstracts selected for presentation at our Scientific Sessions represent the very best cardiovascular imaging research in the United States and around the world,” said Michael Main, M.D., FASE, from Saint Luke’s Mid America Heart Institute, Kansas City, Mo., and ASE 2020 abstract chair. “The breadth and depth of these presentations is truly remarkable, and includes novel applications of advanced technologies such as three-dimensional imaging, ultrasound enhancing agents, and artificial intelligence in both pediatric and adult populations.”

The Alan S. Pearlman Research Award, was given to Priyanka Asrani, MBBS, Boston Children’s Hospital, Boston. This annual award of $1,000 is supported by a grant from Elsevier to the ASE Foundation and is presented to the highest scoring early career investigator. Asrani’s research titled “Technically Successful Fetal Aortic Valvuloplasty Acutely Improves Left Heart Output” focuses on evaluating left heart output before and after fetal aortic valvuloplasty (FAV), a surgery that is done on the fetus in utero. The findings show a significant increase in mitral valve velocity-time interval and blood flow through the left heart after a technically successful FAV. Ultrasound and echocardiography both play a very important role in successfully diagnosing a heart abnormality in a fetus and performing a FAV surgery.

Another research study highlighted in the Top 20 is “To Give or Not to Give? Ultrasound Enhancing Agents Remain Underutilized Tools for the Quantification of Left Ventricular Ejection Fraction.” The use of ultrasound enhancing agents (UEAs) has been demonstrated to improve left ventricular ejection fraction (LVEF) quantification and impact clinical decisions. In this study, researchers from Mount Sinai Hospital in New York, N.Y. found that contemporary guidelines are not sufficiently robust to guide sonographers in the decision to use ultrasound enhancing agents (UEA) and that higher utilization of UEAs is necessary for accurate TTE LVEF quantification.

A study out of Seoul, Korea titled “Global Longitudinal Strain for the Prediction of Sudden Cardiac Death in Patients with Hypertrophic Cardiomyopathy” investigated the predictive value of left ventricular global longitudinal strain (GLS) for sudden cardiac death (SCD) in hypertrophic cardiomyopathy patients. It was found that GLS could better discriminate patients at increased risk of SCD, especially in the low- and intermediate-risk groups. GLS is a robust predictor and provided additive prognostic value to the HCM Risk-SCD model.
