Detecting Heart Disease from Multi-View Ultrasound Images via Supervised Attention Multiple Instance Learning [PDF]

open access: yesMLHC 2023, 2023
Aortic stenosis (AS) is a degenerative valve condition that causes substantial morbidity and mortality. This condition is under-diagnosed and under-treated. In clinical practice, AS is diagnosed with expert review of transthoracic echocardiography, which produces dozens of ultrasound images of the heart.
