Development of three-dimensional cardiac models from computed tomography angiography

Area of Science:

• Veterinary medicine
• Biomedical engineering
• Medical imaging

Background:

• Three-dimensional (3D) modeling and printing are emerging technologies in veterinary cardiovascular medicine.
• Patient-specific 3D models offer diverse applications, including medical teaching, cardiac function assessment, device development, and pre-surgical planning.
• These models improve communication between veterinary teams and pet owners.

Purpose of the Study:

• To highlight the applications and processes of 3D modeling and printing in veterinary cardiovascular medicine.
• To emphasize the role of 3D models in enhancing interventional procedures and veterinary education.

Main Methods:

• Acquiring volumetric imaging data (CT, CMRI, 3D echocardiography).
• Segmenting data using software to create virtual 3D models.
• Refining models with CAD software and 3D printing for physical replicas.

Main Results:

• 3D modeling and printing enable the fabrication of anatomically correct, patient-specific cardiovascular models.
• The reliability of 3D models depends on the quality of the acquired volumetric imaging data.
• Established imaging modalities like CT, CMRI, and 3D echocardiography provide the necessary data.

Conclusions:

• Cardiovascular 3D modeling and printing represent a novel tool in veterinary medicine.
• This technology expands capabilities in planning interventional procedures and practicing surgical skills.
• It significantly aids in communication, education, and the overall advancement of veterinary cardiovascular care.
