Percutaneous transluminal angioplasty of native or recurrent coarctation of the aorta

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Percutaneous transluminal angioplasty of native or recurrent coarctation of the aorta is a minimally invasive procedure aimed at treating the narrowing (coarctation) of the aorta, which is a major blood vessel that carries oxygenated blood from the heart to the rest of the body. This procedure utilizes a transcatheter approach, meaning that a catheter is inserted into the body through a small incision, typically in the groin area, and guided to the site of the coarctation under imaging guidance. The catheter is equipped with a balloon at its tip, which is inflated at the site of the narrowing to widen the aorta and restore normal blood flow. This method is preferred over traditional open surgical techniques due to its reduced invasiveness, leading to shorter recovery times for patients. However, it is important to note that there is a possibility of the coarctation re-narrowing after the procedure, which may necessitate additional interventions, such as repeat balloon angioplasty, to maintain adequate blood flow through the aorta.

1. Indications

The procedure of percutaneous transluminal angioplasty of native or recurrent coarctation of the aorta is indicated for specific clinical scenarios where the aorta is narrowed, leading to compromised blood flow. The following conditions warrant this intervention:

  • Coarctation of the Aorta - This condition involves a congenital or acquired narrowing of the aorta, which can lead to hypertension and reduced blood flow to the lower body.
  • Recurrent Coarctation - Patients who have previously undergone surgical repair of aortic coarctation may experience a recurrence of the narrowing, necessitating this procedure to restore normal blood flow.

2. Procedure

The procedure for percutaneous transluminal angioplasty of native or recurrent coarctation of the aorta involves several critical steps to ensure successful treatment of the narrowed aorta. The following outlines the procedural steps:

  • Step 1: Access Site Preparation - The procedure begins with the preparation of the access site, typically located in the groin area. The skin is cleaned and sterilized to minimize the risk of infection, and local anesthesia is administered to ensure patient comfort during the procedure.
  • Step 2: Catheter Insertion - A sheath is inserted into the iliac artery through the access point. A catheter is then threaded through this sheath and navigated under fluoroscopic imaging guidance toward the aorta. The physician carefully maneuvers the catheter to reach the site of the coarctation.
  • Step 3: Balloon Deployment - Once the catheter is positioned across the narrowed section of the aorta, a balloon at the tip of the catheter is inflated. This inflation expands the artery at the site of the coarctation, effectively widening the lumen and restoring blood flow.
  • Step 4: Balloon Deflation and Catheter Removal - After the balloon has been inflated for a specified duration to achieve optimal dilation, it is deflated and removed along with the catheter. The physician may perform imaging studies to assess the success of the procedure and ensure that the aorta remains adequately expanded.
  • Step 5: Closure of Access Site - Finally, the access site in the groin is closed, and the patient is monitored for any complications or signs of bleeding. Post-procedure care instructions are provided to ensure proper recovery.

3. Post-Procedure

After the completion of the percutaneous transluminal angioplasty, patients are typically monitored in a recovery area for a period to ensure stability and to watch for any immediate complications. It is common for patients to experience a shorter recovery time compared to traditional surgical methods. However, they may be advised to limit physical activity for a few days following the procedure. Follow-up appointments are essential to assess the success of the angioplasty and to monitor for any potential re-narrowing of the aorta, which may require additional interventions. Patients should be educated on signs of complications, such as increased pain, swelling, or changes in circulation, and instructed to seek medical attention if these occur.

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).
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.
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.)
