  Fig. 1. A. Hand paths illustrating performance of Patient 3 on the Visually Guided Reaching (VGR) task before and 3 months after TAVI. Radar plots illustrating B. pre-operative and C. post-operative parameters on VGR. The area between the dashed lines represents average performance. Values greater than the black dashed line (1.64) signify impairment. Values less than the green dashed line (−1.64) signify greater than average performance. The solid black line represents zero on the plotting scale. *Denotes significant change in task score. Unfilled circles represent significant change in parameter value. Patients 2 and 5 did not participate in the 3-month assessment timepoint.

• 

  Fig. 2. A. Hand paths illustrating performance of Patient 7 on the Reverse visually guided reaching (RVGR) task before and 3 months after TAVI. Radar plots illustrating B. pre-operative and C. post-operative parameters on RVGR. The area between the dashed lines represents average performance. Parameters values greater than the black dashed line (1.64) signify impairment. Parameter values less than the green dashed line (-1.64) signify greater than average performance. The solid black line represents zero on the plotting scale. *Denotes significant change in task score. Unfilled circles represent significant change in parameter value. Patients 2 and 5 did not participate in the 3-month assessment timepoint.

• 

  Fig. 3. Radar plots illustrating A. pre-operative and B. post-operative parameters on the TMT-A task. The area between the dashed lines represents average performance. The black dashed line represents 1.64 on the plotting scale. The green dashed line represents -1.64 on the plotting scale. The solid black line represents zero on the plotting scale. *Denotes significant change in task score. Unfilled circles represent significant change in parameter value. Patient 9 was not available to complete the trail making task prior to their TAVI procedure.

  Fig. 4. Radar plots illustrating A. pre-operative and B. post-operative parameters on the TMT-B task. The area between the dashed lines represents average performance. The black dashed line represents 1.64 on the plotting scale. The green dashed line represents -1.64 on the plotting scale. The solid black line represents zero on the plotting scale. *Denotes significant change in task score. Unfilled circles represent significant change in parameter value. Patient 9 was not available to complete the trail making task prior to their TAVI procedure.
