Official Description

Insertion of ventricular assist device, implantable intracorporeal, single ventricle

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The insertion of a ventricular assist device (VAD) is a complex surgical procedure aimed at providing mechanical support to the heart, specifically for patients with severe heart failure or those awaiting a heart transplant. A VAD is an implantable intracorporeal device, meaning that its components, including a mechanical pump, control system, and energy supply, are housed within the body. This type of device is crucial for patients who require assistance in maintaining adequate blood circulation due to compromised heart function. The procedure typically involves a midline chest incision that is extended into the upper abdomen, allowing for the creation of a device pocket where the VAD is placed. The driveline, which connects the device to the external power source, is tunneled from this abdominal pocket into the thoracic cavity. The surgical process may involve the use of cardiopulmonary bypass and cardioplegia to protect the heart during the implantation. Depending on whether a left or right VAD is being placed, specific techniques are employed to secure the device to the heart and ensure proper blood flow. This procedure is critical for improving the quality of life and prolonging survival in patients with significant cardiac impairment.

1. Indications

The insertion of a ventricular assist device (VAD) is indicated for specific clinical scenarios where patients exhibit severe heart failure or require temporary support while awaiting heart transplantation. The following conditions may warrant the use of a VAD:

  • Severe Heart Failure Patients with advanced heart failure who are not responding to medical therapy and are at risk of imminent cardiac death.
  • Heart Transplantation Patients who are on the waiting list for a heart transplant and require mechanical support to maintain adequate circulation until a donor heart becomes available.
  • Post-Operative Recovery Patients who have undergone heart surgery and need additional support to allow for the recovery of one or both ventricles.

2. Procedure

The procedure for the insertion of a ventricular assist device involves several critical steps to ensure proper placement and function of the device. The following outlines the procedural steps:

  • Step 1: Incision and Device Pocket Creation A midline chest incision is made and extended into the upper abdomen. This incision allows access to the thoracic cavity and abdominal area where the device will be implanted. A pocket is created in the upper abdomen to accommodate the VAD.
  • Step 2: Driveline Tunneling The driveline, which connects the VAD to the external power source, is tunneled from the abdominal pocket into the thoracic cavity. This step is crucial for ensuring that the device can be powered without exposing the patient to external components.
  • Step 3: Cardiopulmonary Bypass The patient is placed on cardiopulmonary bypass, which temporarily takes over the function of the heart and lungs during the procedure. Cardioplegia is induced to protect the heart muscle from damage while the device is being implanted.
  • Step 4: Left VAD Placement If a left ventricular assist device is being placed, the apex of the left ventricle is cored, and the inflow cuff is attached to the apex using pledgeted mattress sutures. The cuff is then secured to the VAD, ensuring a stable connection for blood flow.
  • Step 5: Outflow Graft Attachment The length of the outflow graft is determined, and the aorta is partially clamped and incised. An appropriately sized graft is sutured to the aorta, allowing for the outflow of blood from the VAD into the systemic circulation. Once secured, the clamp is released, and the VAD is filled with blood.
  • Step 6: Right VAD Placement If a right VAD is required, the procedure is performed similarly, with an inflow graft placed in the pulmonary artery and an outflow cuff positioned in the right ventricle.
  • Step 7: Weaning from Bypass The patient is gradually weaned from cardiopulmonary bypass, allowing the heart to resume its function while the VAD supports circulation.
  • Step 8: Hemostasis and Closure Suture sites are checked for hemostasis to prevent any bleeding complications. Pacing wires are placed on the heart, and chest tubes are inserted to drain any excess fluid. Drains are also placed in the abdominal pocket to manage any postoperative fluid accumulation. Finally, the chest and abdominal incisions are closed securely.

3. Post-Procedure

After the insertion of the ventricular assist device, patients typically require close monitoring in a critical care setting. Post-procedure care includes managing the patient's hemodynamic status, monitoring for any signs of infection at the incision sites, and ensuring that the VAD is functioning properly. Patients may also need to undergo rehabilitation to adjust to the device and improve their overall cardiovascular health. Follow-up appointments are essential to assess the device's performance and the patient's response to treatment, as well as to make any necessary adjustments to their care plan.

GC This service has been performed in part by a resident under the direction of a teaching physician
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
81 Minimum assistant surgeon: minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number.
