Summary
Three-dimensional (3D) printing offers tangible cardiac anatomy models for planning structural heart disease (SHD) interventions. This technology aids in device testing, training, and communication, improving patient care.
Area of Science:
- Cardiology
- Medical Technology
- Biomedical Engineering
Background:
- Structural heart disease (SHD) encompasses non-coronary cardiovascular disorders requiring complex interventions.
- Current imaging techniques have limitations in precisely defining cardiac anatomy for SHD procedures.
- Catheter-based interventions for SHD have rapidly increased in complexity and type.
Purpose of the Study:
- To review the application, benefits, and challenges of 3D printing in structural heart disease interventions.
- To define the concept, workflow, and clinical integration of 3D printing in cardiology.
- To explore future advancements of 3D printing in SHD treatment planning and training.
Main Methods:
- Review of current literature on 3D printing applications in interventional cardiology.
- Analysis of how 3D printing aids in diagnostic workup and treatment strategy.
- Examination of 3D printing for procedural simulation and interventional training.
Main Results:
- 3D printing provides a tangible representation of cardiac anatomy for improved understanding.
- It enables in vitro testing of interventional devices and procedural planning.
- Applications include enhanced diagnostic workup, treatment guidance, and simulation for training.
Conclusions:
- 3D printing significantly enhances interventional planning and training for structural heart disease.
- It offers improved patient-clinician communication and facilitates hemodynamic research.
- Further development is needed to address existing challenges and maximize clinical benefits.
