Acute coronary syndrome (ACS), also known as heart attack, is a leading cause of morbidity and mortality worldwide, resulting in millions of emergency department (ED) visits and billions in hospital costs each year. Patients at risk are expected to have wall motion abnormalities (WMA) in the area supplied by the affected vessel.
Emergency room and point-of-care clinicians typically order an electrocardiogram (ECG), a blood test and an ultrasound when a patient presents with ACS symptoms. The ultrasound images, which are vitally important given that ECG and blood tests are not always conclusive, are typically viewed visually. The results are often dependent on the clinician’s level of training and experience. Moreover, in the case of the wall motion, detecting abnormality is not possible with the naked eye.
This is where LVivo SAX comes in.
LVivo SAX -First AI-based ultrasound tool, assisting clinicians to detect signs of coronary heart disease
LVivo SAX uses artificial intelligence to analyze segmental left ventricle wall motion using the parasternal short axis view, which is a common cardiac view used in point-of-care ultrasound settings as it provides views of cardiac tissue supplied by all three major coronary vessels and is relatively easy to acquire without manipulating the patient’s posture.
The tool is designed to provide medical clinicians who have varying levels of ultrasound analysis or cardiological experience the ability to automatically measure, track and evaluate cardio functions, and to detect abnormalities that reduce variability and increase efficiency.
Using LVivo SAX at the ED aims to provide reliable and reproducible information to support clinician's decision, by providing auto-analysis of the following AI based parameters:
Segmental Analysis – Wall Motion and Strain
Fractional area change (FAC)
Global Circumferential Strain (GCS)
LVivo SAX also provides segmental function including wall motion evaluation and segmental circumferential straining a “Bullseye” diagram, and segmental score index.
By using LVivo SAX, medical centers may analyze cardiac abnormalities better and therefore optimize echo lab, CT scans and cath lab referrals, as well as reduce hospitalization time for patients.
"LVivo SAX has the potential to change the way we manage patients with suspected acute coronary syndrome"
