Preprocedural computed tomography before cardiac implanted electronic device lead extraction: Indication, technique,...

Area of Science:

• Cardiology
• Radiology
• Medical Imaging

Background:

• Cardiac implantable electronic devices (CIEDs) require extraction for various reasons, including infection or hardware failure.
• Percutaneous extraction is the standard method, though it carries a risk of complications.

Purpose of the Study:

• To review the utility of dedicated pre-CIED extraction imaging using multidetector computed tomography (MDCT).
• To highlight how MDCT can assess lead trajectory, venous integrity, and cardiac structures to anticipate extraction challenges.

Main Methods:

• Review of indications for preprocedural imaging in CIED extraction.
• Description of the MDCT technique for evaluating CIED leads and surrounding anatomy.
• Discussion of image interpretation strategies for identifying potential complications.

Main Results:

• MDCT can visualize lead course, termination, and the condition of central veins and cardiac chambers.
• Preprocedural imaging aids in identifying potential complications that could affect extraction and reimplantation.
• This imaging modality provides crucial anatomical information for planning complex CIED extraction procedures.

Conclusions:

• Dedicated preprocedural MDCT is valuable for evaluating patients undergoing CIED extraction.
• MDCT imaging enhances procedural planning and risk assessment for CIED removal and subsequent lead implantation.
• Optimizing imaging protocols and interpretation is key to maximizing the benefits of MDCT in CIED management.
