Claims

C1strongest claim

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%). Needle placement accuracy improved, with closer membrane proximity (Cliff delta = 0.19) and reduced variability (p < 0.05). NASA-TLX indicated lower cognitive load with multisensory guidance (p < 0.01).

C2weakest assumption

The phantom model and 4D CTA registration sufficiently replicate real clinical challenges of a moving heart under fluoroscopy, including tissue acoustics and needle-tissue interactions, so that observed improvements will translate to live patients.

C3one line summary

Physics-driven sonification via a multilayer membrane model improves needle navigation safety, accuracy, and reduces cognitive load in a cardiologist phantom study for pericardial access.
