Mitral Valve Repair & Replacement


Your doctor and nurse will discuss the risks of the procedure in detail with all patients. Those risks include the following:

  • Bleeding – There’s a small risk of bleeding from the site where the tubes enter the skin. The sites may be closed with a "stitch" or a "glue plug" or may be held by manual pressure after the tubes are removed. Bed rest is necessary for a few hours after the procedure to reduce the chance of bleeding. In a rare situation, a blood transfusion or surgery to repair a damaged blood vessel in the leg may be necessary.
  • Stroke, heart attack, allergy, or kidney injury – There’s a small risk of a stroke, heart attack, allergy or kidney problems related to the intravenous dye, irregular heart rhythm, and rarely death.
  • No improvement in the valve – There’s a small chance that the procedure won’t improve the opening of the valve. In that case, your doctor may discuss scheduling open-heart surgery to replace the valve in the following weeks or months.
  • Valve damage – There’s a small chance that the balloon may damage the valve, which would require open-heart surgery to replace the valve, possibly even that same day; this occurs with approximately 3 in 100 patients.
