Supplementary materials for occluder device endothelialization study.

This supplementary information contains comprehensive data including tabulated baseline characteristics of various occluder devices(Table A), quantitative correlation analyses of factors influencing tissue fibrosis and endothelialization processes (Fig 1‘), scanning electron microscopic characterization of fibrous tissue formation and endothelial cell morphology (Figs 2, 3), and clinical imaging documentation of device-related procedures including surgical explantation of left atrial appendage occlude (Fig 4‘), patent ductus arteriosus (PDA) occluder removal (Fig 5’), and contrast-enhanced imaging of atrial septal occluder integration (Fig 6’).
