Area of Science:

  • Biomedical Engineering
  • Cardiovascular Surgery
  • Medical Imaging and Simulation

Background:

  • Advancements in 3D printing technologies, materials, and interdisciplinary collaboration are driving innovation in cardiovascular interventions.
  • 3D printing offers a promising avenue for enhancing procedural success and educational capabilities in transcatheter aortic valve replacement (TAVR).

Purpose of the Study:

  • To review current applications and future potential of 3D printing in TAVR.
  • To synthesize existing literature and group experience on 3D printing for TAVR.

Main Methods:

  • Literature review of publications on 3D printing for TAVR.
  • Synthesis of internal group experiences and case studies.
  • Analysis of novel 3D printing materials and techniques.

Main Results:

  • Patient-specific 3D models are utilized for TAVR device sizing, procedural complication prediction, and planning complex cases (e.g., valve-in-valve, bicuspid valves).
  • 3D printing aids in investigating TAVR complications and testing hypotheses regarding transcatheter heart valve (THV) implantation.
  • Emerging 3D printable materials are beginning to approximate cardiac tissue properties, enhancing simulation fidelity.

Conclusions:

  • 3D printing is a valuable tool for understanding TAVR challenges and improving procedural outcomes.
  • Innovative benchtop testing and multi-material printing advance the prediction of THV-patient anatomy interaction.
  • These advancements are poised to benefit other structural heart disease interventions, including mitral and tricuspid valve procedures.
