Aortic Valve Disease Screening from PPG via Physiology-Guided Self-Supervised Learning
A physiology-guided self-supervised pretraining scheme for PPG waveforms improved aortic stenosis/regurgitation screening in a UK Biobank cohort (AUROC ~0.76–0.80), but inconsistent reporting and missing ablations temper the claim.
