最近，增强现实（AR）解决方案允许医生在心脏电生理研究中更准确地将消融导管放置在指定的病变部位。导航精度的提高可能会对室性心动过速（VT）消融终止产生积极影响，但在临床中对此进行评估是困难的。新型个性化虚拟心脏技术能够无创地识别梗死相关室速的最佳病灶靶点。本研究旨在评估这种导管导航精度提高对虚拟室速消融的潜在影响。包括2个基于mri的虚拟心脏和2个硅诱导的VT （VT 1, VT 2）。以虚拟的“实相”心内膜消融病变终止VTs。先前在一项评估AR引导下消融导管导航精度改善的临床研究中评估的106个导航误差值（有53个，没有53个）被用来取代“地面真实”消融目标。根据这些误差对相应的烧蚀进行模拟，并对每次模拟的VT终止进行评估。在54例VT - 1消融模拟中，与没有AR的误差相比，AR的较小误差显著导致更多的VT终止（25）（P<0.01）。在52个VT - 2消融模拟中，有AR（11）和没有AR（13）的误差没有显著差异（P=0.58）。基材特性可能会影响精度提高对VT终止的影响。虚拟心脏表明，AR引导所提供的导管导航精度的提高会影响VT终止。
Recently, an augmented reality (AR) solution allows the physician to place the ablation catheter at the designated lesion site more accurately during cardiac electrophysiology studies. The improvement in navigation accuracy may positively affect ventricular tachycardia (VT) ablation termination, however assessment of this in the clinic would be difficult. Novel personalized virtual heart technology enables non-invasive identification of optimal lesion targets for infarct-related VT. This study aims to evaluate the potential impact of such catheter navigation accuracy improvement in virtual VT ablations. 2 MRI-based virtual hearts with 2 in silico induced VTs (VT 1, VT 2) were included. VTs were terminated with virtual “ground truth” endocardial ablation lesions. 106 navigation error values that were previously assessed in a clinical study evaluating the improvement of ablation catheter navigation accuracy guided with AR (53 with, 53 without) were used to displace the “ground truth” ablation targets. The corresponding ablations were simulated based on these errors and VT termination for each simulation was assessed. In 54 VT 1 ablation simulations, smaller error with AR significantly resulted in more VT termination (25) compared to the error without AR (16) (P<0.01). In 52 VT 2 ablation simulations, no significant difference was observed from error with (11) and without AR (13) (P=0.58). The substrate characteristic may impact the effect of improved accuracy to an improved VT termination. Virtual heart shows that the increased catheter navigation accuracy provided by AR guidance can affect the VT termination.
