NCPI-Plus: A Novel TAVR Anchoring Strategy for PAR With Enlarged LVOT.
Transcatheter aortic valve replacement (TAVR) for pure aortic regurgitation (PAR) with an enlarged left ventricular outflow tract (LVOT) remains challenging due to inadequate anchoring.
A 74-year-old woman with severe PAR and an enlarged LVOT (perimeter 93.7 mm), deemed high risk for surgery, underwent TAVR using a 30-mm self-expanding valve. A modified noncoronary sinus pivot implantation (NCPI-plus) technique was performed, deploying the valve above the virtual annular plane on the noncoronary sinus side to create a supra-annular pivot point. Postprocedural imaging and 12-month follow-up confirmed stable anchoring and excellent valve function without regurgitation.
The NCPI-plus technique provides stable anchoring for TAVR in PAR patients with dilated LVOT, by using the supra-annular pivot point on the noncoronary sinus side as its core design to prevent downward valve displacement during deployment.
The NCPI-plus technique offers a feasible anchoring strategy for TAVR in PAR patients with enlarged LVOT.
