Official Description

Removal of permanently implantable aortic counterpulsation ventricular assist system; mechano-electrical skin interface

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 0457T involves the removal of a permanently implantable aortic counterpulsation ventricular assist system, specifically focusing on the mechano-electrical skin interface component. This system is utilized primarily in the management of acute cardiogenic shock or end-stage chronic heart failure. The primary function of the device is to alleviate the workload of the left ventricle while enhancing cardiac output and blood flow, thereby providing critical support to patients with severe heart conditions. The aortic counterpulsation system comprises several key components, including a pneumatic pump, a console that operates the pump using pressurized air, and electrocardiogram electrodes that facilitate synchronization with the patient's heartbeat. The pneumatic pump is surgically implanted into a subcutaneous pocket located above the pectoralis muscle, with a pneumatic drive line exiting through the skin in the right upper abdomen to connect to the console. An interposition vascular graft is surgically anastomosed to the subclavian artery, allowing for the main graft to connect to the pump. Additionally, subcutaneous electrocardiogram electrodes are strategically placed on the chest wall and linked to the console, while mechano-electrical skin interface leads are positioned over the wrist, finger, or ankle to effectively capture the heartbeat and ensure proper synchronization of the pump's operation. During the removal procedure, an incision is made to access the pump, vascular graft, pneumatic drive tubing, and any subcutaneous electrodes present. The procedure requires careful disconnection of the device components, including clamping the vascular graft at the subclavian artery, excising the graft, and repairing the artery. The pneumatic drive tubing and electrodes are also disconnected before the complete removal of the device. This procedure is critical for patients who no longer require the support of the ventricular assist system or who may be transitioning to other forms of treatment.

1. Indications

The procedure associated with CPT® Code 0457T is indicated for patients who have undergone implantation of a permanently implantable aortic counterpulsation ventricular assist system and require its removal. The specific indications for this procedure include:

  • Acute Cardiogenic Shock - A severe condition where the heart suddenly cannot pump enough blood to meet the body's needs, necessitating the use of a ventricular assist device for temporary support.
  • End-Stage Chronic Heart Failure - A progressive condition where the heart's ability to pump blood is severely compromised, leading to the need for mechanical support to improve cardiac output and blood flow.
  • Transition to Alternative Treatments - Patients who may be transitioning to other therapeutic options or who no longer require mechanical support may necessitate the removal of the device.

2. Procedure

The removal of the mechano-electrical skin interface as part of the aortic counterpulsation ventricular assist system involves several critical procedural steps:

  • Step 1: Incision - A surgical incision is made in the skin to access the implanted device. This incision is carefully planned to ensure adequate exposure of the pump and associated components.
  • Step 2: Exposure of the Device - The incision is extended to expose the pump, the subclavian artery, the vascular graft, the pneumatic drive tubing, and any subcutaneous electrodes that may be present. This step is crucial for safely accessing all components of the system.
  • Step 3: Clamping the Vascular Graft - The device is clamped at the subclavian artery to prevent any blood loss during the removal process. This step is essential for maintaining hemostasis.
  • Step 4: Excision of the Vascular Graft - The vascular graft is carefully excised from the subclavian artery. This requires precision to avoid damaging surrounding tissues and to ensure a clean removal.
  • Step 5: Repair of the Subclavian Artery - After the graft is removed, the subclavian artery is repaired using clips or sutures to restore normal blood flow and integrity to the vessel.
  • Step 6: Disconnection of the Pneumatic Drive Tubing - The pneumatic drive tubing is disconnected from the console, which is a critical step in the removal process to ensure that the device is completely detached from its power source.
  • Step 7: Removal of Subcutaneous Electrodes - Any subcutaneous electrodes that were used to monitor the heart's electrical activity are also disconnected and removed, completing the disassembly of the device.
  • Step 8: Complete Device Removal - Finally, the entire unit, including the mechano-electrical skin interface, is removed from the patient's body, concluding the procedure.

3. Post-Procedure

Post-procedure care following the removal of the mechano-electrical skin interface involves monitoring the patient for any signs of complications, such as bleeding or infection at the incision site. Patients may require pain management and should be advised on wound care to promote healing. Follow-up appointments are essential to assess recovery and to ensure that the patient is transitioning effectively to any alternative treatments or therapies that may be necessary following the removal of the device. Additionally, healthcare providers should monitor the patient's cardiac function and overall health status during the recovery period.
