Swin Transformer for Automated Severity Classification of Aortic Regurgitation from Echocardiographic Images: A Multi-Center Study

2026-07-24

Abstract excerpt

<title>Abstract</title> <p>Background Accurate grading of aortic regurgitation (AR) is essential for follow-up, treatment planning, and prognostic assessment. Transthoracic echocardiography is the first-line modality for AR evaluation, but conventional grading depends on image quality, operator experience, and multiparametric interpretation, leading to subjectivity and interobserver variability. This study aimed...
