PURPOSE: To measure and explore complex cardiac anatomy in research and preoperative simulation, a virtual imaging technology-the Vesalius 3D suite (PS Medtech, Amsterdam, Netherlands)-combines Vesalius three-dimensional (3D) image-processing software with an optic-tracking navigation system running PST-Client software. We present a novel method of evaluating dynamic aortic root geometry in vivo using this visualization system.
DESCRIPTION: Based on electrocardiography-gated cardiac computed tomography data in systole and diastole, images of the aortic root in a healthy adult were reconstructed for 3D visualization. Virtual interaction tools were used to explore and measure the aortic root structures.
EVALUATION: Virtually reconstructed images revealed the aortic root internal structures in exquisite detail. Highly accessible 3D interpretation promptly permitted precise measurements of repair-relevant anatomic parameters, including geometrically complex curves of the aortic root wall and dynamic changes in the aortic valves. Measurement accuracy examined against a known prosthesis showed within 1 mm of error (less than 0.5%).
CONCLUSIONS: This technology may promote understanding of aortic root form and function, and facilitate valve-sparing surgery, and seems valuable for 3D exploration and measurement of cardiac anatomy in vivo.
