A Virtual-Reality Imaging Analysis of the Dynamic Aortic Root Anatomy

Area of Science:

• Cardiovascular Imaging
• Medical Technology
• Anatomical Visualization

Background:

• Complex cardiac anatomy requires advanced visualization tools for research and surgical planning.
• Current methods may not fully capture dynamic changes in structures like the aortic root.
• Virtual imaging offers a promising avenue for detailed in vivo anatomical exploration.

Purpose of the Study:

• To present a novel method for evaluating dynamic aortic root geometry in vivo.
• To utilize the Vesalius 3D suite for detailed cardiac anatomy exploration.
• To assess the utility of virtual imaging in preoperative simulation and research.

Main Methods:

• Utilized electrocardiography-gated cardiac computed tomography data from systole and diastole.
• Reconstructed aortic root images for 3D visualization using the Vesalius 3D suite.
• Employed virtual interaction tools for exploration and measurement of aortic root structures.

Main Results:

• Achieved detailed visualization of aortic root internal structures.
• Enabled precise measurements of complex aortic root geometry and dynamic valve changes.
• Demonstrated high accuracy with less than 1 mm error compared to a known prosthesis.

Conclusions:

• The virtual imaging technology provides exquisite detail and precise measurements of aortic root anatomy.
• This approach may enhance understanding of aortic root form and function.
• The system is valuable for in vivo 3D exploration and measurement of cardiac anatomy, potentially aiding valve-sparing surgery.
