New Handheld Device Simplifies heart Valve Disease Detection
Updated June 9, 2025
A new handheld device developed by researchers at the University of Cambridge could revolutionize how doctors screen for heart valve disease. The device offers an easier and more accurate way to record heart sounds compared to customary stethoscopes, possibly leading to earlier diagnosis and treatment.
The device’s design allows for accurate readings even without precise placement on the chest. Its larger, flexible sensing area captures clearer heart sounds, and it can be used over clothing, increasing patient comfort during check-ups and screenings. Researchers are also developing a machine learning algorithm to automatically detect signs of valve disease from the recordings. The findings were published in the IEEE Journal of Biomedical and Health Informatics.
Heart valve disease, frequently enough called the “next cardiac epidemic,” can have a worse prognosis than many cancers. Early detection is crucial, as up to 50% of patients with notable valve disease remain undiagnosed until the condition is advanced.
Professor Anurag Agarwal, from Cambridge’s Department of Engineering, spearheaded the research. He noted the limitations of current diagnostic methods. “The accuracy of stethoscope examination for diagnosing heart valve disease is fairly poor, and it requires a GP to conduct the examination,” Agarwal said.
Agarwal added that echocardiograms,the “gold standard” for diagnosis,frequently enough involve long waiting lists. The new device aims to bridge this gap by providing a user-pleasant screening tool that can be used by various health professionals.
The device, about the size of a drinks coaster, contains six sensors and materials that transmit vibration through clothing. Gel between the sensors prevents interference, ensuring accurate readings. Initial tests involved healthy participants with diverse body types. The next step involves clinical trials comparing the device’s performance against echocardiogram results.
The researchers believe this device could be an affordable and scalable solution for heart health screening,particularly in areas with limited resources. It could also help prioritize patients awaiting echocardiograms, ensuring those with suspected valve disease are seen sooner.
What’s next
The researchers plan to conduct clinical trials to validate the device’s effectiveness in detecting heart valve disease in a real-world setting. They also aim to refine their machine learning algorithm to improve its accuracy in identifying the condition.
