Butterfly Network Advances AI-Powered Aortic Valve and Aorta Screening with
Aortic stenosis, a narrowing of the aortic valve, affects over 13% of Americans over 75 years old and is often missed until it’s advanced and symptomatic. Studies(1, 2) suggest that a significant number of AS cases remain undiagnosed, particularly among underserved and aging populations. This delay in diagnosis is associated with higher risk procedures, worse outcomes, and increased healthcare costs. As earlier identification and treatments of AS are increasingly associated with better patient outcomes, the need for upstream, accessible screening is critical.
“This research shows a promising path forward where lower-level providers, not just cardiologists or trained sonographers, could screen for aortic stenosis using AI-assisted handheld ultrasound,” said Dr.
The study validated that an ML model trained on hospital-grade ultrasound images performed well when adapted to Butterfly’s handheld ultrasound device. After fine-tuning the final layer of a neural network, researchers achieved an area under the receiver operator characteristic curve (AUROC) of 0.94 for differentiating between no aortic stenosis and any degree of aortic stenosis on handheld ultrasound images – a level of accuracy that supports potential clinical use in screening workflows.
In a related development, Butterfly has just released the latest expansion of its Butterfly ScanLab™ AI-powered ultrasound education app: an Aorta Exam Protocol. This educational app harnesses animations, anatomical labeling, and a quality indicator to help teach users how to scan the abdominal aorta and recognize normal anatomy. With that training, users can then use POCUS to detect life-threatening conditions like abdominal aortic aneurysms (AAA) and dissections. Designed for ease of use on an iPad, the module is included in every Butterfly membership and compatible with existing Butterfly probes.
