At TCT 2025, Professor Zhang Xiaochun from Zhongshan Hospital, representing the teams of Academician Ge Junbo, Professor Zhou Daxin, and Professor Pan Wenzhi, presented groundbreaking research titled "Noncoronary Sinus Pivot Implantation (NCPI) Strategy for TAVR with Self-Expanding Valve in Pure Native Aortic Regurgitation." 

The study demonstrated that using the NCPI strategy with the self-expanding TaurusElite valve system in pure native aortic regurgitation (PNAR) patients significantly improved device success rates and reduced complication risks, offering a new global solution for AR intervention.

The innovative NCPI technique establishes a stable pivot above the noncoronary sinus base, enabling stable valve deployment and anchoring while allowing the lower valve edge to extend into the LVOT and right coronary sinus for improved coaptation and support. Results showed the NCPI group achieved a remarkable 98.8% device success rate, significantly outperforming the non-NCPI group's 81.1% (p<0.001).
