Explainable machine learning and unsupervised anatomical phenotyping of mitral valve prolapse in patients with severe mitral regurgitation

CONCLUSION: Explainable and unsupervised analyses concordantly identified a MAD-enriched, BD-dominant bileaflet/multiscallop MVP phenotype, supporting the concept that MAD is embedded within broader annular-leaflet remodeling rather than being an isolated binary abnormality.
