Official Description

Percutaneous balloon valvuloplasty; pulmonary valve

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Percutaneous balloon valvuloplasty is a minimally invasive procedure aimed at treating a stenosed, or narrowed, heart valve, specifically the pulmonary valve in this context. This procedure is performed by accessing the heart through a blood vessel, typically one of the femoral arteries located in the groin. The term "percutaneous" refers to the method of accessing the heart through the skin, which allows for a less invasive approach compared to traditional surgical methods. During the procedure, continuous imaging guidance is utilized to ensure accurate placement of the catheter and to monitor the heart's anatomy and function. The primary goal of balloon valvuloplasty is to dilate the narrowed valve, thereby improving blood flow and reducing the symptoms associated with valve stenosis. This procedure is particularly important for patients who may be at high risk for open-heart surgery or those who require immediate relief from symptoms caused by the obstruction of blood flow through the heart. The technique involves several critical steps, including the measurement of intracardiac and intra-arterial pressures to assess the severity of the stenosis and the effectiveness of the dilation once completed.

1. Indications

The procedure of percutaneous balloon valvuloplasty is indicated for patients who present with a stenosed pulmonary valve, which can lead to significant cardiovascular complications. The following conditions may warrant the performance of this procedure:

  • Stenosis of the Pulmonary Valve - A narrowing of the pulmonary valve that restricts blood flow from the right ventricle to the pulmonary artery, leading to increased pressure in the right ventricle and potential heart failure.
  • Symptoms of Heart Failure - Patients exhibiting symptoms such as shortness of breath, fatigue, or chest pain due to the obstruction caused by the narrowed valve.
  • Increased Right Ventricular Pressure - Elevated pressures in the right ventricle as measured during diagnostic evaluations, indicating the need for intervention to relieve the obstruction.

2. Procedure

The percutaneous balloon valvuloplasty procedure involves several critical steps to ensure successful dilation of the pulmonary valve:

  • Step 1: Accessing the Artery - The procedure begins with the preparation of the skin over the access artery, typically one of the femoral arteries. A needle is used to puncture the artery, and a sheath is placed to facilitate the introduction of catheters.
  • Step 2: Insertion of Guidewire - Using continuous imaging guidance, a guidewire is inserted through the sheath and advanced from the access artery through the aorta and into the heart, reaching the opening of the stenosed pulmonary valve.
  • Step 3: Catheter Placement - A catheter is then advanced over the guidewire and positioned within the heart. The guidewire is subsequently withdrawn, allowing for the measurement of intracardiac and intra-arterial pressures by placing the catheter tip in the appropriate heart chambers and arteries.
  • Step 4: Pressure Measurements - To assess the severity of the stenosis, pressures are measured in the right atrium, right ventricle, and pulmonary artery. This step is crucial for determining the need for balloon dilation.
  • Step 5: Contrast Injection and Angiography - Contrast material is injected through the catheter, and angiography is performed to visualize the valve and measure the valve annulus, which is essential for planning the dilation.
  • Step 6: Catheter Exchange - The initial catheter is exchanged for a wire-positioning catheter, allowing for the advancement of a guidewire through the stenosed valve.
  • Step 7: Balloon Valvuloplasty Catheter Advancement - A balloon valvuloplasty catheter is advanced over the guidewire and positioned at the center of the valve annulus, ready for dilation.
  • Step 8: Dilation of the Valve - The balloon is inflated to dilate the narrowed valve. This inflation may be repeated several times to achieve the desired level of dilation.
  • Step 9: Post-Dilation Pressure Measurements - After the dilation is completed, intracardiac and intra-arterial pressures are measured again to evaluate the effectiveness of the procedure.
  • Step 10: Completion Angiogram - A final angiogram is performed to assess valve mobility and the filling of cardiac chambers and great vessels, ensuring that the procedure has successfully improved blood flow.

3. Post-Procedure

Following the percutaneous balloon valvuloplasty, patients are typically monitored for any complications and to assess the immediate effects of the procedure. Expected recovery may involve a short hospital stay, during which vital signs and heart function are closely observed. Patients may experience some discomfort at the access site, which usually resolves quickly. Follow-up evaluations, including echocardiograms, are often scheduled to monitor the function of the pulmonary valve and to ensure that the dilation has been effective in relieving symptoms and improving blood flow. Additional considerations may include the management of any underlying conditions and the assessment of the need for further interventions based on the patient's overall health and response to the procedure.

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.)
