Automated Screening for Aortic Stenosis
||Validation of System for Automated Screening for Aortic Stenosis
Aortic Stenosis, Structural Heart Disease
Aortic stenosis (AS) affects over 12.6 million adults and causes an estimated 102,700 deaths annually. There is interest in novel approaches to identify valve disease earlier the disease course before symptoms occur. We previously used machine learning (ML) to develop a system for fully automated AS screening. Here we are validating the performance of this new me
- Referred for clinically indicated transthoracic echocardiography
- Prior valve replacment procedure
The study design involves 10 minutes of additional image acquisition after a routine transthoracic echocardiography. Point of care ultrasound (POCUS) data acquisition is non-invasive and by design appropriate for population screening. The acquisition will be similar to the imaging exam that was just completed (as part of routine care) but with a different device (Butterfly IQ+ device). This is a commercially available POCUS device. The POCUS imaging will be saved, encrypted, and uploaded to a HIPAA compliant cloud in standard fashion for automated analysis.
