Three-dimensional (3D) strain echocardiography and point of care ultrasound are both high-tech diagnostic tools highlighted in two research studies being presented during the 29th Annual ASE Scientific Sessions. Both technologies represent the safe, inexpensive, and worldwide use of echocardiography for the well-being of patients.

In the first study, researchers from Children's Hospital of Michigan in Detroit, MI, evaluated heart function using a novel 3D real-time strain echocardiography (heart ultrasound) technique in 31 children who had received anthracycline chemotherapy (Adriamycin) for cancer more than one year prior to enrollment, in comparison to 82 normal controls. Senior author, Sanjeev Aggarwal, MD, said, “Although the cancer-treated children did not have any heart-related symptoms and had normal function shown on a traditional echocardiogram, we detected significant decrease in 3D global longitudinal and circumferential strain measures, and systolic dyssynchrony index. Torsion and twist, additional measures of heart function which have been shown to be abnormal in adults who had received cancer medications, were comparable to normal controls in our pediatric study. We need to further assess the progression of these abnormalities over time in children.”

Authors on the study, “Three Dimensional Real Time Strain Echocardiography in Children Following Chemotherapy: A Novel Diagnostic Tool” include Gilda Kadiu, Yamuna Sanil, Ahmad M. Charaf-Eddine, and Sanjeev Aggarwal, from Children's Hospital of Michigan, Detroit, MI. Ms. Kadiu will present a poster based on this research on Sunday, June 24, 2018 at the Gaylord Opryland Resort & Convention Center.

A second research study highlights how using small, portable echocardiography devices can help make important cardiovascular diagnoses in resource-poor settings, especially in lower and middle income countries that face growing incidence, morbidity, and mortality from cardiovascular disease. Researchers from across the U.S., Australia, and Vietnam invited residents of Vietnam to participate in a one-day cardiovascular outreach as a part of routine village outreaches through the Vietnam National Heart Institute in 2015 and 2017. 653 participants were recruited at one site in Dong Anh district and two sites in Thanh Hoa province in northern Vietnam. “Innovation in echocardiography has powerful diagnostic implications. As technological developments allow increasingly sophisticated assessment of cardiac structure and function, and therefore improved diagnosis and care of patients, it is important to remember that miniaturization of echo machines continues to make the power of cardiac ultrasound available to underserved populations. This study in Vietnam demonstrates the value of echocardiography in resource-poor settings, above and beyond electrocardiograms, which record the electrical signals in your heart, to diagnose clinically important cardiac pathology. Finding these diseases in the community setting facilitates early treatment of conditions and may help with triaging patients to medical centers, saving on transportations costs for families living on the edge. The partnership of the ASE Foundation with the Vietnam National Heart Institute in conducting this and other studies has demonstrated the benefit of echocardiographic outreach in under-resourced areas.”
