Enabling Automated Device Size Selection for Transcatheter Aortic Valve Implantation

Figure 6

The agreement between prosthesis sizes from the Edwards Sapien 3 (a) and Medtronic Evolut TAVR sizing chart (b). The plots represent how many sizes were selected for each available device size based on the model, observer 1, and observer 2. The arrows between the plots indicate disagreement with observer 1 (under- or overestimation). The weights indicate the number of patients that were sized differently as compared to observer 1.
