Figure 4

Cross sectional and longitudinal CT angiography views of the Reducer in the coronary sinus 6 months after implantation. The flow of contrast demonstrates continued patency of the device. The green and red bars in the longitudinal image, on the right, mark the positions of the cross-sectional images shown on the left. The red bars that appear in the third cross-sectional image and in the longitudinal image are in the same relative position in the two images and mark the positions of the opposing walls of the Reducer.
