AI stethoscope listens for heart trouble, may replace costly scans

This study tested whether a computer program (AI) can analyze heart sounds recorded with a special stethoscope to find common valve problems like aortic stenosis and mitral regurgitation. Researchers compared the AI's results to standard tests like echocardiograms (heart ultrasound) or cardiac catheterization. The goal is to see if this quick, bedside listening test could someday help diagnose heart valve disease without needing more expensive or invasive procedures.
