May 2019 | FDA grants clearance for eMurmur ID, heart murmur detection solution on a personal mobile device

May 7, 2019

eMurmur® today announced that its flagship “eMurmur ID” solution has received FDA clearance, enabling a new era in heart murmur detection. eMurmur ID is a mobile and cloud solution which operates in conjunction with a 3rd party electronic stethoscope. It uses advanced machine learning to identify and classify pathologic and innocent heart murmurs, the absence of a heart murmur, and S1, S2 heart sounds. The end-to-end solution is comprised of AI-based analytics, a mobile app, and a web portal (all HIPAA compliant). It supports the workflows of healthcare providers performing cardiac auscultation and has multiple applications including primary and specialty care, and corporate health.

Heart Murmur Detection: Past vs Future
Heart disease is the leading cause of death globally for both men and women, causing 31% of all deaths annually. Heart auscultation (meaning “to listen with a stethoscope”) is a 200+ year-old method to screen for heart disease by listening for abnormal heart sounds (murmurs), used worldwide for patients of all ages. However, heart auscultation is subjective in nature and studies have shown accuracy rates amongst primary care providers to be as low as 20-25%. With an accuracy rate of over 85%, eMurmur ID makes expert-level auscultation accessible to any healthcare provider performing auscultation.

“The eMurmur ID solution has the potential to disrupt medical care”, said Dr. Derek Exner, Professor and Canada Research Chair in Cardiovascular Clinical Trials at the University of Calgary. “The evidence for its utility is solid and includes five studies on over 1000 patients, including blinded, multi-centre trials. This system has been shown to be accurate, informative, and easy-to-use. It provides healthcare professionals with a potent screening tool and method to confirm their clinical diagnoses, enhancing patient care.”

“Receiving FDA clearance marks a significant milestone in our company’s history, and I’m very excited to finally be able to take the eMurmur ID solution to market,” said Andreas Schriefl, co-founder and CEO of eMurmur. “We believe that eMurmur ID has the potential to disrupt the status-quo of heart murmur screening and significantly reduce costs to healthcare systems worldwide.”

“From a technology perspective, receiving FDA clearance requires solid clinical proof of the algorithm performance characteristics, as well as a quality and risk management system that ensures patient safety and compliance with stringent regulatory standards,” said Andreas Reinisch, co-founder and CTO of eMurmur. “Through this process, our company has gained significant knowledge and expertise to facilitate and support future AI- based medical solutions,”

April 2019 | eMurmur releases Primer, accredited by Partners in Healthcare Education, LLC, accredited by the American Association of Nurse Practitioners

This month, we launched eMurmur Primer, an accredited app designed for nurse practitioners and nurses to improve their cardiac auscultation skills while earning continuing education credits. Creating an interactive and practical app for nurses took several months of development as we worked closely with several nurse practitioners and nurses to identify what they wanted in an app. We took their feedback to heart and used the library of 1,000 cardiologists-vetted, patient heart sounds from our clinical trials to design an app that would prime their cardiac auscultation skills. We partnered with top medical institutions to gather our research and design a straightforward continuing education course for use by any busy nurse. In one recent survey, we found that 7/10 nurses were not confident in identifying benign or pathological heart murmurs. To improve confidence in hearing heart murmurs and understanding the heart, we designed Primer based on the 3 Keys to Mastering Cardiac Auscultation by Cardiologist John P. Finley in his book Teaching Heart Auscultation to Health Professionals.

Download our app for free to understand heart anatomy, identify normal heart sounds versus abnormal, the difference between benign and pathological murmurs, and differentiate between murmurs that warrant further evaluation and those that do not with eMurmur Primer.

March 2019 | eMurmur Heartpedia launches in the Google Play and Apple App Store

Today, eMurmur announced the release of eMurmur Heartpedia, an app designed to help patients, parents and medical professionals to better understand heart defects through anatomically-correct 3D models and corresponding heart and murmur sound recordings for each defect. eMurmur Heartpedia is a major upgrade of the original Heartpedia app from Cincinnati Children’s Hospital Medical CenterCentre which has been downloaded over 100,000 times since its release in 2014.

"Congenital heart defects can be difficult to visualize, understand, and explain. Supplying easy-to-understand information on heart defects and established surgical repair strategies can result in improved comprehensive care for the patient,” says Peace Madueme, MD MS FAAP FACC FASE at Nemours Children’s Hospital in Orlando. "eMurmur Heartpedia is unique in that it provides validated patient heart sounds, 3D cardiac models and videos in an easy- to- use app that is accessible and understandable by anyone."

“The rich visual and audio heart information in eMurmur Heartpedia make it much easier to understand heart defects, which we expect will be invaluable to families, healthcare professionals, medical and nursing schools.” says Andreas Schriefl, founder and CEO of eMurmur

eMurmur Heartpedia is a downloadable app that runs on a mobile device such as a smartphone or tablet, and is available from both the IOS and Android app stores. Check out eMurmur Heartpedia in the Google Play and Apple App store.

Dec 2018 | Johns Hopkins study demonstrates 88% accuracy of eMurmur, as published in Pediatric Cardiology

Results from a study called "Artificial Intelligence-Assisted Auscultation of Heart Murmurs: Validation by Virtual Clinical Trial" have been published in the peer-reviewed journal of Pediatric Cardiology. This is the first reported comprehensive and objective evaluation of an AI-based murmur detection algorithm, and included 3180 heart sound recordings from 603 outpatient visits. Algorithm estimation of heart rate was similar to gold standard. Sensitivity and specificity for detection of pathologic cases were 93% (CI 90–95%) and 81% (CI 75–85%), respectively, with accuracy 88% (CI 85–91%). In conclusion, the eMurmur algorithm tested has high sensitivity and specificity for detection of pathologic murmurs, similar to levels reported for specialist auscultation, making it a potentially useful screening tool for heart disease.
