Are VR measurements as accurate as CT planning software for TAVI?

“The analysis showed no significant differences between the measurements and strong correlations with correlation coefficients between 0.874 and 0.994, P < 0.001.”

between 0.874 and 0.994

“The intraclass correlation coefficient (ICC) confirmed excellent consistency for annular measurements (ICC = 0.93), while the concordance correlation coefficient indicated very good overall agreement (CCC = 0.83, 95% CI 0.73-0.90).”

ICC = 0.93

“A higher level of agreement between the two software systems was observed for linear metrics (short, long, and average diameter).”

“There were no significant differences but strong correlations between the VR measurements compared with those performed with the 3mensio software.”

“Virtual reality visualization of the left atrium and appendage based on MSCT data is feasible and allows precise and reproducible measurements in planning of LAA occlusion procedures with enhanced 3D orientation.”

“AR (8 studies) enhanced intraoperative accuracy, reducing pedicle screw placement errors (98% vs. 91.7% control) and procedure times (e.g., 50% faster spinal screw placement).”

“Preoperatively, XR has been shown to evaluate mitral annular pathology more accurately than echocardiography, informing the surgeon about the optimal surgical technique, approach and plan for a particular patient's MV pathology.”
