Name of the Procedure:

Repositioning of Previously Implanted Transvenous Pacemaker or Implantable Defibrillator Electrode (Right Atrial or Right Ventricular)

Summary

This procedure involves adjusting the position of an electrode that has previously been implanted in the right atrium or right ventricle of your heart. This electrode is part of a pacemaker or implantable defibrillator system, which helps manage heart rhythm disorders.

Purpose

The procedure aims to correct issues like improper electrode positioning, which can lead to ineffective pacing or defibrillation. The goal is to ensure the device functions optimally, maintaining a regular heart rhythm and preventing serious cardiac events.

Indications

• Symptoms like dizziness, fainting, or irregular heartbeats
• Diagnostic tests indicating poor electrode placement or function
• Ineffective pacing or defibrillation
• Patient criteria: Those with an already implanted pacemaker or defibrillator experiencing issues with electrode placement

Preparation

• Pre-procedure fasting as advised by the doctor
• Medication adjustments, particularly blood thinners
• Diagnostic tests such as an ECG or echocardiogram to assess cardiac function

Procedure Description

1. The patient is given local anesthesia or mild sedation.
2. A small incision is made near the device implantation site.
3. The existing electrode is carefully repositioned within the heart's right atrium or ventricle.
4. The new position is tested using real-time imaging and electrical testing to ensure optimal function.
5. The incision is closed, and a dressing is applied.

Duration

The procedure typically takes 1-2 hours.

Setting

This procedure is usually performed in a hospital's cardiac catheterization lab or electrophysiology suite.

Personnel

• Cardiologist or cardiac electrophysiologist
• Nurses
• Anesthesiologist or sedation nurse

Risks and Complications

• Infection at the incision site
• Bleeding or bruising
• Damage to the heart or blood vessels
• Lead dislodgement or device malfunction
• Rarely, arrhythmias or cardiac perforation

Benefits

• Improved device performance and heart rhythm control
• Reduced symptoms of arrhythmias
• Prevention of serious cardiac events

Recovery

• Monitor in a hospital for a few hours or overnight
• Pain management with prescribed medications
• Avoid heavy lifting or vigorous activity for a few weeks
• Follow-up appointments to ensure proper device function

Alternatives

• Medication adjustments
• External pacing or defibrillation temporarily
• Complete replacement of the device, if necessary

Patient Experience

During the procedure, the patient might feel some pressure or slight discomfort at the incision site but should not feel pain due to anesthesia. Post-procedure, mild pain or discomfort at the incision site can be managed with painkillers. The patient might experience some restrictions on activity but should notice an improvement in symptoms once recovered.
