Can a Smartphone Listen to Your Heart? A Performance Study on Detecting Abnormalities in Your Heart Sounds

Condition(s) studied

Investigational drug(s) / intervention(s)

Computer algorithms: Collection of lightweight computer algorithms called ausculto™ that is designed to perform real-time heart sound analysis to detect heart murmur.

Study summary

This observational study aims to assess the performance of the software called ausculto™. ausculto™ is a collection of computer algorithms that intend to analyse heart sounds recorded from the built-in microphone of a smartphone for abnormal sounds.

Participants will have their heart sounds recorded during their regular clinic appointment after consenting to participate in this study.

Researchers will manually annotate the recorded heart sounds to create a database for use in future training and testing of artificial intelligence (AI) intended for medical uses.

Eligibility

Primary outcome measure(s)

• Sensitivity of ausculto™ Using Auscultation Paired with Echocardiography as Ground Truth — Day 0
  Sensitivity is defined as the percentage of true positives out of all positive cases from the ground truth. Cardiologist electronic stethoscope heart sound recording annotations paired with echocardiography diagnosis will be used as the ground truth. Heart sound recordings from electronic stethoscope will be rated by two independent cardiologists for presence or absence of murmur, with a third cardiologist consulted in case of disagreement.
• Specificity of ausculto™ Using Auscultation Paired with Echocardiography as Ground Truth — Day 0
  Specificity is defined as the percentage of true negatives out of all negative cases from the ground truth. Cardiologist electronic stethoscope heart sound recording annotations paired with echocardiography diagnosis will be used as the ground truth. Heart sound recordings from electronic stethoscope will be rated by two independent cardiologists for presence or absence of murmur, with a third cardiologist consulted in case of disagreement.
