Histopathological observation of PLLA ASD occluders by HE staining and IHC at different follow-up points of 3 (A), 6 (B), 12 (C), 24 (D) months. Green arrows indicated the PLLA ASD occluder. Blue arrows indicated fibroblasts, collagen fibers, inflammatory cells or multinuclear giant cells. Red arrows indicated the endothelial cells in the new endocardium. Black arrows indicated the endothelial cells in new small vessels. PLLA: poly L-lactide. ASD: atrial septal defect. HE: haematoxylin-eosin. IHC: immunohistochemistry
