case_images: TEE images depicting thrombi in the left atrium before treatment. TEE images depicting thrombi in the left atrium (LA) as dog-like shapes that appeared to be connected to the entrance of the right upper pulmonary vein (RUPV) and the right lower pulmonary vein (RLPV) (arrows). The thrombi included a large white area and were linear in shape. The blood flows from the RUPV and RLPV are shown as red areas (arrowheads).. LA, left atrium; RLPV, right lower pulmonary vein; RUPV, right upper pulmonary vein

case_images: FIG1
case_images: The LA thrombi had no periodical movement with heartbeats (Fig. 1 and Video 1). 80-MDCT demonstrated no thrombi in the LA; however, the RLPV appeared darker, indicating thrombi in the RLPV (Fig. 2).
case_images: TEE images revealing thrombi in the left atrium. TEE images revealing thrombi in the left atrium (LA) that appeared to be connected to the entrance of the right upper pulmonary vein (RUPV) and right lower pulmonary vein (RLPV). The thrombi, including the large white area, were linear in shape and did not clearly move inward. The blood flows from the RUPV and the RLPV are shown as red areas.. TEE images obtained after six months of edoxaban treatment. TEE images obtained after six months of edoxaban treatment revealing thrombi in the LA that appeared to be connected to the entrance of the right upper pulmonary vein (RUPV) and right lower pulmonary vein (RLPV). The thrombi, including some white areas, were curved and did not move extensively. The blood flows from the RUPV and the RLPV are shown as red areas. The thrombi moved more toward each other than in Video 1.. TEE images obtained after 18 months of edoxaban treatment. TEE images obtained after eighteen months of edoxaban treatment revealing thrombi in the LA that appeared to be connected to the entrance of the right upper pulmonary vein (RUPV) and right lower pulmonary vein (RLPV). The thrombi, including the small white area, were curved and periodically moved inward. The blood flows from the RUPV and the RLPV are shown as red areas.

case_images: The LA thrombi had no periodical movement with heartbeats (Fig. 1 and Video 1). 80-MDCT demonstrated no thrombi in the LA; however, the RLPV appeared darker, indicating thrombi in the RLPV (Fig. 2). However, the hyperechoic area of the thrombi decreased, and the shape of the thrombi showed curved areas (Fig. 3 and Video 2). 80-MDCT demonstrated no thrombi in the LA; however, the RLPV appeared clearer than previously observed (Fig. 4).
case_images: Oblique images from an 80-MDCT scan revealing the RUPV, RLPV, and LA before treatment. Oblique images from an 80-MDCT scan revealing the RUPV, RLPV, and LA; the location was similar to that in the TEE images in Figure 1. There were no images of thrombi in the left atrium (arrow). Additionally, there was a rather dark area in the RLPV.. LA, left atrium; RLPV, right lower pulmonary vein; RUPV, right upper pulmonary vein

case_images: However, the hyperechoic area of the thrombi decreased, and the shape of the thrombi showed curved areas (Fig. 3 and Video 2). 80-MDCT demonstrated no thrombi in the LA; however, the RLPV appeared clearer than previously observed (Fig. 4).
case_images: Oblique images from an 80-MDCT scan obtained after six months of edoxaban treatment. Oblique images from an 80-MDCT scan obtained after six months of edoxaban treatment revealing the RUPV, RLPV, and LA; the angle was similar to that of the TEE images in Figure 3. There were no images of thrombi in the LA (arrow). The dark area of the RLPV became slightly clearer, indicating that the thrombi had partly resolved.. LA, left atrium; RLPV, right lower pulmonary vein; RUPV, right upper pulmonary vein

case_images: However, the hyperechoic area of the thrombi decreased and became much darker, and the thrombi were curved (Fig. 5) and moved periodically with increasing heartbeat (Video 3). 80-MDCT demonstrated no thrombi in the LA, and the RLPV appeared clearer than previously observed (Fig. 6).
case_images: TEE images obtained after 18 months of edoxaban treatment. TEE images obtained after eighteen months of edoxaban treatment revealing thrombi in the LA that appeared to be connected to thrombi in the RUPV and RLPV (arrows). The shape of the thrombi, including the small, rather white area, was curved. The thrombi connected to the RUPV seemed to become broader.. LA, left atrium; RLPV, right lower pulmonary vein; RUPV, right upper pulmonary vein
