Microprocessor control unit for use with electric ventricular assist device, replacement only
HCPCS code
Name of the Procedure:
Common name(s): Microprocessor Control Unit Replacement Technical term: Replacement of Microprocessor Control Unit for Electric Ventricular Assist Device
Summary
This procedure involves replacing the microprocessor control unit of an electric ventricular assist device (VAD), which is a machine that helps the heart pump blood in patients with severe heart failure. The microprocessor control unit is a critical component that ensures the VAD functions correctly.
Purpose
This procedure addresses malfunctions or failures in the microprocessor control unit of an electric VAD. The goal is to restore the proper function of the VAD, thereby enabling it to continue assisting the heart in pumping blood efficiently.
Indications
- Malfunction or failure of the microprocessor control unit in an electric VAD
- Alarming signs from the device indicating a control unit issue
- Decreased VAD performance affecting patient health
Preparation
- The patient may need to fast for several hours before the procedure.
- Adjustments to current medications, as advised by the healthcare provider.
- Pre-procedure diagnostic tests such as ECG, blood tests, and imaging studies to assess heart function.
Procedure Description
- The patient is positioned and prepared in a sterile environment.
- Local or general anesthesia is administered.
- The existing microprocessor control unit is accessed, typically through a small incision.
- The malfunctioning unit is carefully detached and removed.
- A new microprocessor control unit is inserted and connected to the VAD.
- The new unit is tested to ensure it is functioning properly.
- The incision is closed and secured with sutures or surgical glue.
Duration
The procedure typically takes about 1 to 2 hours.
Setting
This procedure is performed in a hospital or specialized surgical center.
Personnel
- Cardiothoracic surgeon
- Anesthesiologist
- Surgical nurse
- Biomedical technician
Risks and Complications
- Infection at the incision site
- Bleeding
- Anesthesia-related complications
- Device malfunction
- Blood clots or stroke
- Rejection of the device
Benefits
- Restored functionality of the VAD
- Improved blood circulation
- Enhanced overall heart function
- Reduced symptoms of heart failure
Recovery
- Observational stay in the hospital for monitoring.
- Post-procedure care, including wound cleaning and medication adjustments.
- Recovery time is usually around 1 to 2 weeks.
- Follow-up appointments to monitor device performance and patient health.
Alternatives
- Reprogramming the existing control unit, if possible.
- Total replacement of the VAD.
- Heart transplant for eligible patients.
- Medical management of heart failure with medications and lifestyle changes.
Patient Experience
During the procedure, the patient will be under anesthesia and should not feel pain. Post-procedure, there may be some discomfort or pain at the incision site, which can be managed with prescribed pain relievers. The healthcare team will provide instructions for care and activity restrictions during recovery to ensure optimal healing and device functionality.
