Adult cardiac & structural heart: How often does VR change the surgical plan?

“Overall, senior physicians reported that XR influenced their surgical decisions more, suggesting that the utility of XR varies with physician experience and patient age.”

“However, because routine empirical ablation of the left PV carina is not part of our standard strategy, this finding did not lead to a predefined modification of the initial ablation plan.”

“The incision site marking made using HoloLens® 2 differed by one intercostal space from the marking made using a conventional surgeon's mental reconstructed image from the patient's preoperative imaging and was found to be a more appropriate site of entry”

“In Patient 1, virtual reality simulation revealed that, according to the distance and angulation from the annulus, the ideal puncture site was the second intercostal space.”

“Processed images and virtual reality showed intense adherences of the leads to the veins, right ventricle, and right atrium endocardium and between them that preclude a difficult extraction and required a carefully planning and sometimes a different technical approach.”

“In 33% of cases (two out of six), the preoperative decision was adjusted due to the 3D VR-based evaluation of the anatomy.”

“The surgical strategy was adjusted in 11.8% of the cases due to the 3-dimensional virtual reality-based anatomy evaluation.”
