Eko Foundation Analysis Software with Transformers (EFAST) vs Fetal EchoScan
Similar category, different focus. These tools serve overlapping but distinct needs.
Comparability 60/100
Comparability is an AI-graded 0–100 score of how directly these two tools compete — higher means a more apples-to-apples comparison.
AI Verdict
These tools are adjacent in the broader cardiology AI landscape but serve distinct clinical needs. EFAST is designed for adult patients, leveraging AI with digital stethoscopes to detect structural murmurs and atrial fibrillation during routine exams. In contrast, Fetal EchoScan focuses on prenatal care, utilizing AI-powered ultrasound to screen for congenital heart defects in fetuses.

Frequently Asked Questions
EFAST is designed to assist clinicians in identifying structural murmurs associated with heart disease and detecting atrial fibrillation during routine exams in adult patients. Fetal EchoScan, conversely, is an AI-powered ultrasound screening software that aids in the prenatal detection of congenital heart defects in fetuses during second-trimester anatomic ultrasound exams.
EFAST is an AI model that integrates seamlessly with Eko digital stethoscopes to provide real-time analysis during auscultation. Fetal EchoScan is a cloud-based software-only device that integrates with existing ultrasound workflows and machines, providing real-time guidance and feedback during ultrasound scans.
EFAST assists in the detection of structural murmurs associated with heart disease and atrial fibrillation. Fetal EchoScan is designed for the automated detection of congenital heart defects (CHDs) during prenatal ultrasound examinations.
EFAST boasts a 93% sensitivity and 91% specificity for structural murmur detection, and a 95% sensitivity and 94% specificity for atrial fibrillation detection. Fetal EchoScan is stated to reduce false-negative and false-positive errors in CHD detection and provides automated evaluation of fetal heart morphological signs suspicious for severe fetal heart defects, though specific sensitivity and specificity percentages are not provided.
EFAST is intended for use in Cardiology, Family Medicine, and Internal Medicine. Fetal EchoScan is designed to support Cardiology, Maternal-Fetal Medicine, and Radiology specialties.
