BACKGROUND: Anatomical evaluation under physiologic status is quite important to achieve various kinds of cardiac procedures. We introduced novel workstations which create 3D Hologram Virtual Reality (3D-VR) images in the field of cardiovascular surgery. We present 3D-VR evaluation in the aortic root surgery including valve sparing aortic root surgery (VSARS) and aortic valve leaflet reconstruction (AVLRS) as well as complicated procedures of endovascular aortic repair (EVAR).
METHODS: Enrolled patients underwent enhanced ECG-triggered cardiac or enhanced thoracic, abdominal, and pelvic CT. Axial images were obtained early and late phase of enhanced images. DICOM data of these CT images were installed a 3-D workstation, EchoPixel Ture3D.
RESULTS: 1) VSARS: 3D-VR analysis could indicate important information preoperatively and clarify distortion of three commissures and deviation of nadirs, which were not easy to identify even intraoperative findings. 2) AVLRS: 3D-VR image analysis had notably provided valuable information for understanding of precise anatomy of the aortic root, especially excessive deviation toward the left ventricle on the nadir of non-coronary. In bicuspid aortic valve cases, we could design and simulate all procedures using 3D-VR image preoperatively as a "navigation" of the surgery. 3) EVAR: EVAR technique for complicated abdominal and iliac aneurysm required various kinds of technique. 3D-VR analysis was useful to clarify the precise branching direction of small branches.
CONCLUSIONS: 3D-VR image analysis had notably provided valuable information for understanding of precise anatomy under physiological condition in 3-D specific condition. Further growth in the field of structural heart disease or intraoperative imaging would be promising.
