Description
Norio Tada and colleagues study, in a 2026 retrospective analysis, how to line up a replacement aortic valve with the heart's natural seams during catheter implantation. Good alignment eases future coronary access and repeat procedures. The Navitor Vision valve travels on a flexible delivery system that can twist unpredictably on its way through the aorta.
Patients treated between April 2025 and March 2026 were split by strategy period. One approach set rotation low in the descending aorta. The other adjusted it higher in the ascending aorta under CT-guided views. Ascending adjustment improved final alignment, while the low setting often failed to hold. Timing of the twist mattered, and no rotation-related complications occurred. Operators get a practical handling lesson for this device.
