Herein, we report the successful use of a snare technique to facilitate valve delivery in a patient with a previously stented aortic coarctation and poststenotic dilatation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case summary<\/jats:title>\n                    <jats:p>A 66-year-old woman with Turner syndrome, prior aortic coarctation stenting, and surgical bioprosthetic aortic valve replacement presented with symptomatic severe prosthetic aortic valve stenosis. Advancement of a 23-mm Medtronic Evolut FX valve was hindered by the small caliber of the patent aortic stent and marked aortic tortuosity. A gooseneck snare was used to apply inferior traction while the delivery system was advanced from the contralateral femoral access, redirecting the catheter toward the center of the stented segment and enabling successful valve deployment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Snare-assisted redirection represents a valuable adjunctive strategy to facilitate self-expanding TAVR valve delivery in patients with complex or previously stented aortic anatomy.
