However, advancing a needle toward the thin and moving pericardium remains highly challenging and risky. To address this problem, we present a physics-driven sonification method for Extended Reality (XR)-based multisensory navigation to enhance user perception during the critical needle landing phase in PEA.\n  Dynamic cardiac anatomy from 4D CTA was reconstructed and registered to a real-world coordinate system. Real-time needle tracking provided the position of the needle tip re"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"The multisensory method significantly improved navigation safety (χ² = 11.30, p < 0.01), reducing myocardial contact (3.64% vs. 7.27%) and increasing correct access (90.91% vs. 52.73%).
