Summary
Severe intravascular hemolysis occurred after mitral valve repair. Re-operation with prosthetic valve replacement successfully stopped the hemolysis, likely caused by a regurgitant jet hitting repair materials.
Area of Science:
- Cardiovascular Surgery
- Hematology
Background:
- Mitral valve repair is a common cardiac procedure.
- Hemolysis, the destruction of red blood cells, can be a rare complication after cardiac surgery.
Observation:
- A patient developed severe intravascular hemolysis post-mitral valve repair.
- Mild to moderate mitral regurgitation was noted, but hemolysis was the primary reason for re-operation.
Findings:
- Prosthetic valve replacement led to an immediate resolution of hemolysis.
- The hemolysis is postulated to result from a regurgitant jet impacting Teflon pledgets used during the initial repair.
Implications:
- This case highlights a potential cause of hemolysis after mitral valve repair.
- Careful assessment of regurgitant jets and material placement is crucial to prevent such complications.
