Device extraction is increasingly common. This article details advanced techniques for transvenous lead extraction and leadless pacemaker retrieval, emphasizing multidisciplinary collaboration for safer procedures.
Area of Science:
- Cardiology
- Cardiac Surgery
- Electrophysiology
Background:
- The number of cardiac implantable electronic devices (CIEDs) has significantly increased over the past decade.
- Consequently, the need for CIED extraction procedures has also risen.
- These procedures are inherently risky and require careful planning.
Purpose of the Study:
- To review current and emerging techniques for transvenous lead extraction.
- To discuss methods for retrieving leadless pacemakers.
- To highlight the importance of multidisciplinary collaboration in CIED extraction.
Main Methods:
- Discussion of traditional transvenous lead extraction techniques.
- Exploration of non-traditional and advanced extraction methods.
- Review of strategies for leadless pacemaker retrieval.
Main Results:
- Evolving tools and techniques are improving the safety and efficacy of CIED extraction.
- Multidisciplinary collaboration is crucial for successful pre-procedural planning and complication mitigation.
- Both leaded and leadless CIED extraction present unique challenges and require specialized approaches.
Conclusions:
- Device extraction is a growing field requiring specialized expertise.
- Continuous innovation in extraction technology enhances patient safety.
- Team-based approaches involving cardiothoracic surgeons, cardiac anesthesiologists, and electrophysiologists are essential for optimal outcomes in CIED extraction.

Sampling Methods: Sample Types
Solid samples include a variety of substances, such as sediments from water bodies, soil, metals, and biological tissues. Two standard methods for extracting sediments from water bodies are grab sampling and piston coring. Grab sampling involves using a device to collect a discrete sediment sample from the bottom of a water body with minimal disturbance. Grab samples do not always represent the entire area due to...
