Glossary Entry: Intracardiac Catheter


Definition: An intracardiac catheter is a medical device used to access the interior chambers of the heart for diagnostic or therapeutic purposes. It enables direct visualization and intervention within the cardiac structures, allowing for precise assessments and treatments.

Detailed Description

Types and Variations

Variations: Intracardiac catheters come in various sizes and configurations, including diagnostic and therapeutic models. They may also differ in the specific features and functions, such as navigation capabilities or imaging modalities.


Common Uses: Intracardiac catheters are commonly used for procedures such as cardiac ablation, electrophysiological studies, biopsy, and intracardiac echocardiography. These devices play a crucial role in the diagnosis and treatment of cardiac arrhythmias, structural abnormalities, and other cardiac conditions.

Insertion and Placement

Procedure: The insertion and placement of an intracardiac catheter require meticulous guidance and precision. Specific techniques, such as the Seldinger technique, may be utilized to access the cardiac chambers safely and accurately.

Clinical Considerations

Potential Complications

Risks: Potential complications associated with intracardiac catheterization include cardiac perforation, thromboembolism, infection, and vascular injury. Careful monitoring and adherence to procedural guidelines are essential to mitigate these risks.

Care and Maintenance

Maintenance Requirements: Proper care and maintenance of intracardiac catheters involve meticulous sterilization, storage, and handling to prevent contamination and ensure optimal performance during subsequent uses.

Additional Information
