Official Description

Valvuloplasty, mitral valve, with cardiopulmonary bypass; radical reconstruction, with or without 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 techniques employed depend on the nature and severity of the valve's damage or malformation. The procedure may involve various methods, including annuloplasty to reduce the size of the valve orifice, the use of autologous pericardial patches for leaflet repair, and reconstruction of the chordae tendineae if they are ruptured or elongated. The complexity of the repair can vary, with radical reconstruction being performed in some cases, which may or may not involve the use of a prosthetic ring. This comprehensive approach aims to restore the normal function of the mitral valve and improve the patient's overall cardiac health.

1. Indications

The mitral valvuloplasty procedure is indicated for the following conditions:

  • Mitral Valve Prolapse - A condition where the mitral valve leaflets bulge into the left atrium during heart contraction, potentially leading to regurgitation.
  • Mitral Valve Regurgitation - Occurs when the mitral valve does not close tightly, allowing blood to flow backward into the left atrium, which can lead to heart failure and other complications.

2. Procedure

The procedure for mitral valvuloplasty involves several critical steps to ensure effective repair of the mitral valve:

  • 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, allowing for a still and bloodless surgical field.
  • Step 4: Exposing the Mitral Valve - An incision is made in the left atrium to expose the mitral valve, providing the surgeon with access to assess the valve's condition and determine the appropriate repair techniques.
  • Step 5: Performing Valve Repair - The type of repair performed is based on the specific damage or malformation of the valve. If the valve annulus is dilated, an annuloplasty may be performed, which involves plicating the edges of the valve to reduce the orifice size. If a ring annuloplasty device is utilized, the annulus is sized, and the ring is secured with sutures. Additionally, if the valve leaflets are damaged, they may be repaired using an autologous pericardial patch. In cases where the chordae tendineae are ruptured or elongated, they may be resected and plicated, or replaced with special sutures. Other techniques may include transferring or transposing chordae from one leaflet to another to restore proper function.
  • Step 6: Closing the Heart - After the repair is completed, the incision in the heart is closed, and the patient is gradually weaned off cardiopulmonary bypass. Chest tubes may be placed as necessary to drain any excess fluid, and the chest is then closed securely.

3. Post-Procedure

Post-procedure care for patients undergoing mitral valvuloplasty includes monitoring in a recovery area to ensure stable vital signs and proper heart function. Patients may require pain management and will be observed for any signs of complications, such as bleeding or infection. The placement of chest tubes allows for the drainage of fluid and helps prevent complications related to fluid accumulation. The expected recovery period can vary, but patients are typically advised on activity restrictions and follow-up appointments to assess the success of the procedure and the function of the mitral valve. Rehabilitation may be recommended to aid in recovery and improve overall cardiovascular health.
