Figure 2. CT-predicted risk of compromised coronary flow and access after redo-TAVI.

Figure 2

A) Based on the redo-TAVI criteria, the lowest risk for coronary flow compromise occurs when an S3 is placed at node 4 of the Evolut frame, and redo-TAVI is feasible 80% of the time. The risk of coronary flow compromise is variable based on the implantation depth of the S3. For Evolut-in-Evolut placed inflow-to-inflow, 29% of cases are at low risk for coronary flow compromise. B) Based on the redo-TAVI criteria, the lowest risk for coronary inaccessibility occurs when an S3 is placed at node 4 of the Evolut frame. S3-in-Evolut inflow-to-inflow is an approximation, and the node level is dependent on the size. It correlates with S3 outflow at node 4 for the 26 mm Evolut and S3 outflow at node 5 for the 29 mm and 34 mm Evolut valves.
