Summary
Left bundle branch pacing (LBBP) is a physiological pacing method. Three-dimensional (3D) printing models confirm optimal lead placement, aiding physicians in achieving successful LBBP and reducing the learning curve.
Area of Science:
- Cardiovascular Interventions
- Medical Device Technology
- Cardiac Electrophysiology
Background:
- Left bundle branch pacing (LBBP) is increasingly utilized for physiological cardiac pacing.
- Successful LBBP requires precise lead tip orientation, perpendicular to the interventricular septum (IVS).
- Lead placement challenges can lead to LBBP procedural failure.
Observation:
- Three-dimensional (3D) printing offers a novel approach for simulating cardiovascular interventions.
- A patient-specific 3D heart model was generated from a case with successful LBBP.
- The 3D model accurately depicted the lead tip positioned perpendicularly to the IVS.
Findings:
- The 3D printed heart model successfully demonstrated the optimal lead tip orientation for LBBP.
- This visualization confirmed the perpendicular relationship between the lead tip and the IVS in a successful case.
- The model serves as a valuable tool for understanding critical lead placement parameters.
Implications:
- 3D printing technology can enhance the understanding of optimal lead placement in LBBP.
- This approach has the potential to significantly shorten the learning curve for early-career operators.
- Utilizing 3D models may improve procedural success rates and patient outcomes for LBBP.
