Official Description

Valvuloplasty, aortic valve, open, with cardiopulmonary bypass; complex (eg, leaflet extension, leaflet resection, leaflet reconstruction, or annuloplasty)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 33391 involves a complex valvuloplasty of the aortic valve, which is a critical surgical intervention performed to repair the aortic valve through an open chest incision while utilizing cardiopulmonary bypass. The aortic valve, situated between the left ventricle and the aorta, consists of three cusps or leaflets that regulate blood flow from the heart to the body. Over time, various factors such as infection, aging, and congenital defects can lead to the aortic valve becoming stiff and narrowed, a condition known as stenosis, which restricts blood flow. Alternatively, the leaflets may become loose and floppy, resulting in regurgitation, where blood flows back into the ventricle instead of moving forward into the aorta. To access the heart for this procedure, a surgeon typically makes an anterior midline incision in the chest, which involves opening the sternum, or alternatively, an intercostal incision may be made between two ribs on the left side of the chest. The use of cardiopulmonary bypass is essential during this surgery; it is initiated by placing a venous cannula in the right atrium, vena cava, or femoral vein, and an atrial cannula in the aorta, femoral or axillary artery, or apex of the heart. This allows for the heart to be temporarily stopped and cooled, facilitating the surgical repair of the valve. In the context of complex valvuloplasty, various techniques are employed to restore the function of the aortic valve. These may include leaflet extension, resection, reconstruction, or annuloplasty, each aimed at addressing specific structural issues with the valve. The complexity of the procedure necessitates careful planning and execution to ensure optimal outcomes for the patient.

1. Indications

The procedure of complex valvuloplasty of the aortic valve is indicated for patients experiencing significant aortic valve dysfunction due to various underlying conditions. These indications include:

  • Stenosis - A condition where the aortic valve becomes narrowed, limiting blood flow from the heart to the aorta, often due to calcium buildup or age-related changes.
  • Regurgitation - Occurs when the aortic valve leaflets do not close properly, allowing blood to flow backward into the left ventricle, which can lead to heart failure if untreated.
  • Congenital defects - Structural abnormalities present at birth that affect the aortic valve's function, potentially necessitating surgical intervention.
  • Infective endocarditis - An infection of the heart valves that can damage the aortic valve, leading to dysfunction and requiring surgical repair.

2. Procedure

The complex valvuloplasty procedure involves several critical steps to effectively repair the aortic valve. These steps include:

  • Accessing the heart - The surgeon begins by making an incision in the chest, either through an anterior midline approach by opening the sternum or through an intercostal incision between two ribs. This provides direct access to the heart.
  • Initiating cardiopulmonary bypass - A venous cannula is placed in the right atrium, vena cava, or femoral vein, and an atrial cannula is inserted into the aorta, femoral or axillary artery, or apex of the heart. This allows the heart to be temporarily stopped and blood to be diverted for oxygenation.
  • Cooling the heart - The heart is cooled, and medications may be administered to halt muscle contractions, ensuring a still and bloodless surgical field for the repair.
  • Performing the valvuloplasty - The surgeon makes an incision in the heart to expose the aortic valve. For complex cases, techniques such as leaflet extension, where pericardial tissue is sutured to the leaflets, or leaflet resection, where a wedge of tissue is removed, may be employed. Additionally, annuloplasty may be performed by attaching a ring to the leaflets to maintain the desired annulus size.
  • Inspecting and repairing chordae or papillary muscles - These structures are evaluated for any damage and repaired as necessary to ensure proper valve function.
  • Restarting heart contractions - Once the repairs are completed, the heart's muscle contractions are restarted, and the valve is checked for any signs of bleeding.
  • Weaning off cardiopulmonary bypass - The patient is gradually taken off the bypass machine, allowing the heart to resume its normal function.
  • Closing the chest - Drainage tubes are placed to manage any fluid accumulation, and the chest cavity is closed securely.

3. Post-Procedure

After the complex valvuloplasty procedure, patients typically require close monitoring in a recovery unit. Post-operative care includes managing pain, monitoring vital signs, and ensuring proper heart function. Patients may need to stay in the hospital for several days to recover fully. Follow-up appointments are essential to assess the success of the procedure and to monitor for any complications, such as bleeding or infection. Rehabilitation may also be recommended to help patients regain strength and improve cardiovascular health.

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).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) 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.
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
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).
