Repositioning of previously implanted subcutaneous implantable defibrillator electrode
CPT4 code
Name of the Procedure:
Repositioning of Previously Implanted Subcutaneous Implantable Defibrillator Electrode (S-ICD Electrode Repositioning)
Summary
The procedure involves adjusting the position of a subcutaneous implantable defibrillator electrode. This electrode is a part of a device designed to monitor and correct irregular heartbeats. Repositioning may be necessary if the electrode has moved from its initial position or is not functioning correctly.
Purpose
The procedure addresses problems with the placement of a subcutaneous implantable defibrillator electrode, which can affect its ability to detect and treat arrhythmias effectively.
Indications
- Failure of the defibrillator to detect arrhythmias correctly
- Discomfort or pain at the implant site
- Inappropriate defibrillator shocks
- Electrode migration detected through imaging tests
Preparation
- Fasting may be required for several hours before the procedure
- Review of current medications with potential adjustments
- Pre-procedure imaging or assessments, such as an ECG or chest X-ray
Procedure Description
- The patient is placed under local or general anesthesia.
- An incision is made near the site of the existing electrode.
- The defibrillator electrode is carefully repositioned to ensure optimal placement.
- The new position is verified using imaging techniques.
- The incision is closed with sutures and a sterile dressing is applied.
Duration
The procedure typically lasts about 1 to 2 hours.
Setting
Performed in a hospital setting, usually in a specialized cardiac catheterization lab or surgical suite.
Personnel
- Cardiologist or electrophysiologist (often the primary operator)
- Surgical nurse
- Anesthesiologist (if general anesthesia is used)
Risks and Complications
- Infection at the incision site
- Bleeding or hematoma formation
- Damage to the electrode or surrounding tissues
- General anesthesia-related risks (if applicable)
- Risks specific to individual patient health conditions
Benefits
- Improved defibrillator function
- Enhanced detection and treatment of arrhythmias
- Reduced discomfort or inappropriate shocks
- Benefits are often realized immediately or shortly after the procedure
Recovery
- Monitoring in a recovery room for a few hours post-procedure
- Instructions for wound care and activity restrictions
- Follow-up appointments to monitor the implant and check proper electrode function
- Full recovery typically within a week, with restrictions on strenuous activities for a few weeks
Alternatives
- Medication adjustments to manage arrhythmias
- External defibrillator use as a temporary measure
- Potential surgical revision to fix any underlying issues with the implant
Patient Experience
- Possible discomfort or mild pain at the incision site, managed with prescribed medications
- Minimal activity within the first 24-48 hours post-procedure
- Gradual return to normal activities over a week, with specific instructions from the healthcare provider
