Official Description

Valvuloplasty, mitral valve, with cardiopulmonary bypass; with prosthetic ring

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Mitral valvuloplasty is a surgical procedure aimed at correcting issues with the mitral valve, which is situated between the left atrium and the left ventricle of the heart. This procedure is primarily indicated for patients suffering from mitral valve prolapse and regurgitation, conditions characterized by the improper closure of the mitral valve. In mitral valve prolapse, the valve leaflets bulge upward into the left atrium during the contraction of the left ventricle, leading to a situation where blood can leak back into the atrium, known as regurgitation. The surgical approach typically involves accessing the heart through a median sternotomy or a right anterolateral thoracotomy, allowing for direct visualization and intervention on the mitral valve. During the procedure, cardiopulmonary bypass is established to maintain circulation and oxygenation of the blood while the heart is temporarily stopped. The surgical team initiates cardioplegia to protect the heart muscle during the operation. An incision is made in the left atrium to expose the mitral valve, and the specific repair technique is determined based on the nature and severity of the valve's damage. If the valve annulus is found to be dilated, an annuloplasty may be performed to reduce the size of the valve orifice, often utilizing a prosthetic ring for support. The procedure may also involve repairing the valve leaflets and addressing any issues with the chordae tendineae, which are the structures that help anchor the valve leaflets. Overall, mitral valvuloplasty with cardiopulmonary bypass and the use of a prosthetic ring is a complex but critical intervention aimed at restoring proper function to the mitral valve and improving the patient's quality of life.

1. Indications

Mitral valvuloplasty is performed for the following indications:

  • Mitral Valve Prolapse - A condition where the mitral valve leaflets bulge into the left atrium during heart contraction.
  • Mitral Valve Regurgitation - A condition characterized by the leakage of blood back into the left atrium due to improper closure of the mitral valve.

2. Procedure

The procedure for mitral valvuloplasty with cardiopulmonary bypass and the use of a prosthetic ring involves several critical steps:

  • Step 1: Accessing the Heart - The surgical team begins by performing a median sternotomy or a right anterolateral thoracotomy to gain access to the heart. This allows for direct visualization and manipulation of the mitral valve.
  • Step 2: Establishing Cardiopulmonary Bypass - Once access is achieved, cardiopulmonary bypass is initiated to take over the function of the heart and lungs, ensuring that blood is circulated and oxygenated while the heart is temporarily stopped.
  • Step 3: Initiating Cardioplegia - Cardioplegia is administered to protect the heart muscle during the procedure by inducing a state of temporary cardiac arrest.
  • Step 4: Exposing the Mitral Valve - An incision is made in the left atrium to expose the mitral valve, allowing the surgeon to assess the valve's condition and determine the appropriate repair technique.
  • Step 5: Performing Annuloplasty - If the valve annulus is dilated, an annuloplasty is performed to reduce the size of the valve orifice. This may involve plicating the edges of the valve orifice or placing a prosthetic ring to support the annulus.
  • Step 6: Repairing the Valve Leaflets - The valve leaflets may be repaired using an autologous pericardial patch, and if the chordae tendineae are damaged, they may be resected and reconstructed or replaced with special sutures.
  • Step 7: Closing the Heart Incision - After the necessary repairs are completed, the incision in the heart is closed, and the patient is gradually weaned off cardiopulmonary bypass.
  • Step 8: Post-Procedure Care - Chest tubes are placed as needed to drain any excess fluid, and the chest is closed to complete the surgical procedure.

3. Post-Procedure

Following the mitral valvuloplasty procedure, patients typically require close monitoring in a recovery setting. The expected recovery process may involve managing pain, monitoring for any complications, and ensuring proper heart function. Patients may have chest tubes in place to facilitate drainage of fluid from the chest cavity. The duration of the hospital stay can vary based on individual recovery, but patients are generally observed for several days before being discharged. Follow-up appointments are essential to assess the success of the procedure and to monitor the patient's overall cardiac health.

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).
GC This service has been performed in part by a resident under the direction of a teaching physician
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.
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).
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.
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).
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).
CC Procedure code change (use 'cc' when the procedure code submitted was changed either for administrative reasons or because an incorrect code was filed)
