Heart Disease : Mitral Valve Regurgitation and Mitral Valve Replacement : Risks & Complications

Risks of Mitral valve replacement vary according to the patient’s pre-existing problems or other associated defects.

Overall risk involved in degenerative mitral valve disease surgery is 0.4%. Risk of death is about 7% and thrombosis is about 5%.

Risk of death is high in patients with preoperative renal insufficiency, cerebrovascular disease, unstable angina and elderly patients.

The complications related to surgery are as follows:

  • Infection – Skin infections can be treated with proper antibiotics. Breastbone infection is a rare but serious complication. It may even result in the removal of the breastbone or death.
  • Bleeding
  • Blood clots because of the mechanical valve.
  • Thromboembolism – Blood clots travels in the blood and occludes a different artery.
  • Prosthetic Valve Infection – This is more common than infection of the native valve.
  • Valve failure (less than 0.01%). Another replacement surgery is required to correct this problem.
  • Heart attack during or immediately after surgery (0.004%).
  • Stroke (1%)

Mitral Valve repair is preferred in most patients where replacement can be avoided. The long-term outcomes are good for both, better in mitral valve repair. However, long-term results can be influenced by other pre-existing conditions.
