Name of the Procedure:

Battery Replacement for Ventricular Assist Device (Non-Lithium-Ion)

Summary

This procedure involves replacing the battery of an electric or electric/pneumatic ventricular assist device (VAD) with a new one, which isn't lithium-ion. The VAD is a mechanical pump that supports heart function and blood flow in individuals with weakened hearts.

Purpose

The procedure is essential for ensuring the proper functioning of a ventricular assist device. The main goals are to restore reliable power to the VAD and maintain its functionality, thereby supporting adequate blood circulation and heart performance.

Indications

• Device alert or alarm indicating a battery issue.
• Routine battery replacement as part of maintenance.
• Patient experiences symptoms of VAD failure such as fatigue, dizziness, or shortness of breath.
• Decreased battery performance or lifespan.

Preparation

• Pre-procedure consultation to review medical history and existing health conditions.
• Instructions to continue or adjust usual medications.
• No special fasting needed unless instructed otherwise by the healthcare provider.
• Routine blood tests and an echocardiogram to evaluate heart function.

Procedure Description

1. Patient is positioned comfortably and the replacement procedure is reviewed.
2. Existing VAD battery is carefully disconnected by a trained healthcare professional.
3. New non-lithium-ion battery is connected to the VAD, ensuring proper attachment and function.
4. VAD is tested to confirm it's operating correctly with the new battery.
5. Patient is monitored for any immediate complications.

Tools and Equipment: Non-lithium-ion battery, VAD connection tools, monitoring equipment.

Anesthesia or Sedation: Typically not required; local anesthesia may be used for device area discomfort.

Duration

The procedure typically takes about 30 minutes to an hour.

Setting

Usually performed in an outpatient clinic or dedicated VAD center.

Personnel

• Cardiologist or VAD specialist.
• Nurse or technician trained in VAD management.
• Possible involvement of anesthesiologist if local anesthesia is applied.

Risks and Complications

• Minor risk of infection at connection site.
• Temporary discomfort or pain.
• Rare risk of VAD malfunction.
• Potential for allergic reaction to the battery material.

Benefits

• Ensures continuous, reliable operation of the VAD.
• Promotes heart health and symptom relief.
• Allows the patient to maintain an active lifestyle.

Recovery

• Monitoring for a few hours post-procedure for immediate complications.
• Routine daily activities can usually be resumed shortly after the procedure.
• Follow-up appointments scheduled to ensure ongoing VAD function.

Alternatives

• Continuous VAD management and battery checks to delay replacement.
• Upgrading to a newer VAD system if deemed necessary by a healthcare provider.

Pros: Non-invasive, quick recovery, reliable power source. Cons: Requires periodic replacement, potential minor procedure risks.

Patient Experience

• Should expect minimal discomfort during the procedure.
• The process is generally straightforward and involves routine checks rather than invasive surgery.
• Post-procedure, patients may feel relief from symptoms and improved overall device functionality.
• Pain management includes over-the-counter pain relievers if needed, and comfort measures are provided throughout care.
