3D Model Guiding Transcatheter Aortic Valve Replacement in a Patient With Aortic Coarctation

Area of Science:

• Cardiovascular Surgery
• Medical Imaging
• Biomedical Engineering

Background:

• Transcatheter aortic valve replacement (TAVR) requires precise vascular access planning.
• Complex patient anatomy poses significant challenges to successful TAVR procedures.
• Traditional imaging modalities may not fully capture intricate vascular details.

Observation:

• A patient presented with complex vascular anatomy, including aortic coarctation, severe iliofemoral disease, and a tortuous left subclavian artery.
• A patient-specific, 3-dimensional (3D) printed model was utilized for pre-procedural planning.
• The 3D model facilitated detailed visualization of the patient's unique vascular structures.

Findings:

• The 3D printed model accurately represented the complex vascular anatomy.
• It enabled effective planning of the optimal vascular access route for TAVR.
• The model assisted in anticipating and mitigating potential access-related complications.

Implications:

• 3D printing offers a valuable tool for enhancing surgical planning in complex cardiovascular interventions.
• This technology can improve patient outcomes and procedural safety in TAVR.
• Personalized anatomical models can guide complex vascular access strategies.
