This case study presents a novel technique for mitral valve replacement in high-risk patients. Continuous blood perfusion via the coronary sinus protected the heart during surgery on a beating heart.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Anesthesia
  • Cardiopulmonary Bypass

Background:

  • Mitral valve replacement is often necessary but carries risks.
  • Conventional techniques using cardioplegic arrest increase myocardial injury risk in high-risk patients.

Observation:

  • A patient requiring mitral valve replacement was deemed high-risk for conventional surgery.
  • The procedure was performed on a beating heart using cardiopulmonary bypass.

Findings:

  • The heart was continuously perfused with oxygenated, normothermic, noncardioplegic blood via the coronary sinus.
  • This approach successfully protected the myocardium during the beating-heart procedure.

Implications:

  • This technique offers a potential alternative for high-risk patients undergoing mitral valve replacement.

  • Coronary sinus perfusion may mitigate myocardial injury during cardiopulmonary bypass.
  • Further studies are warranted to validate this approach in a larger cohort.
