Gross examination of tissues around the device: (a) and (b) show the pcVSDO surface covered a slice of intact thicken membrane at 7 days after closure of defect. No dislocation, thrombus formation, and device fracture were observed. (c) shows the surface and surrounding of the commercial occluder presented a large number of neotissue, while (d) shows the tissue was significantly reduced compared to the commercial occluder.
