  FIGURE 1. After LAAC, the occluder fell off into the aortic arch and was feathered out, before the 33-mm Watchman device was occluded again. (A,I,J) LA TEE images. (A) Preoperative LAA: ostial of 25–30 mm and an effective depth of 28 mm. (I,J) Two-dimensional and 3-dimensional images after the second closure with the Watchman device. (B,C,E,F,H) DSA images. (B) Preoperative LAA with an opening of 28 mm and a depth of 31 mm. (C) After occlusion with the 33-mm Watchman device. (E,F) Endoscopic Raptor forceps were used to clamp the umbrella trabeculae and drag it into the sheath. (H) Second closure with the Watchman device. (D,K) Chest CT image. (D) Occluder in the aortic arch. (K) LAAC with the Watchman device. (G) Modified occluder.

  FIGURE 2. After LAAC, the occluder detached into the LA and was retrieved, before the Lacbes 2834 device was occluded again. (A,B,I) TEE images. (A) Preoperatively, the diameter of the LAA opening was 18.3–22 mm and the diameter of the anchoring area was 16.5–24.4 mm. (B) The Lacbes 2834 was placed in LAA, the fixed column was exposed, and the residual shunt at the upper edge was 4.3 mm. (I) After the second LAAC procedure with Lacbes 2636, the covering disc adhered well and had no residual shunt. (C–H,J) DSA images. (C) Preoperatively, the diameter of the LAA change opening was 28.56 mm and the diameter of the anchoring area was approximately 31.47 mm. (D) After closure with the Lacbes 2834 device. (E) The Lacbes fell into the LA. (F–H) Endoscopic Raptor forceps were used to clamp the umbrella trabeculae and drag them into the sheath. (J) After the second LAAC procedure with the Lacbes 2636 device.
