Why the study?
Three-dimensional aortic root evaluation using virtual reality techniques for valve-sparing aortic root replacement preparation had not yet been implemented.
Does preoperative virtual reality computed tomography (VR-CT) accurately measure aortic root geometry compared to intraoperative measurements in patients undergoing valve-sparing aortic root replacement?
Does preoperative virtual reality computed tomography (VR-CT) accurately measure aortic root geometry compared to intraoperative measurements in patients undergoing valve-sparing aortic root replacement?
Preoperative VR-CT provides accurate 3D anatomical measurements of the aortic root that strongly correlate with intraoperative findings, potentially aiding in graft size selection for valve-sparing aortic root replacement.
BACKGROUND: Three-dimensional aortic root evaluation using virtual reality (VR) techniques for valve-sparing aortic root replacement (VSARR) preparation has not yet been implemented, so we demonstrated VR computed tomography (VR-CT) and assessed its utility for VSARR. METHODS AND RESULTS: =0.79). Furthermore, mean GH was observed to be significantly different among the selected graft size groups; therefore, the preoperative mean GH could play a significant role in graft sizing. CONCLUSIONS: VR-CT evaluation allows a thorough understanding of aortic root anatomy, which could facilitate VSAAR.
