Assessment of Left Ventricular Filling Pressure by Applying Artificial Intelligence Algorithms to Left Atrial Speckle-tracking Echocardiography

This study is using artificial intelligence to analyze special heart ultrasound (echocardiogram) images of the left atrium, with the goal of more accurately measuring the pressure inside the heart's left ventricle — a key marker of heart failure. **You may be eligible if...** - You are 18 or older - You are not pregnant - You can provide good quality heart ultrasound images (good acoustic window) - You have consented to participate **You may NOT be eligible if...** - You are unwilling to participate - Your heart ultrasound images are of poor quality - You have more than mild mitral valve disease, significant aortic regurgitation, a heart valve prosthesis on the left side, or previous mitral valve repair - You have a condition that prevents accurate measurement of heart strain Talk to your doctor to see if this trial is right for you.
