Mitral valve repair complications can arise from patch detachment, leading to acute mitral regurgitation. Careful surgical technique is crucial to avoid tension and ensure repair integrity.
Area of Science:
- Cardiovascular Surgery
- Cardiac Valve Repair
- Mitral Valve Disease
Background:
- Severe mitral regurgitation (MR) often necessitates mitral valve (MV) repair.
- Posterior leaflet augmentation is a technique used in MV repair.
- Coronary artery bypass grafting (CABG) may be performed concurrently.
Observation:
- A 65-year-old male developed acute MR with pulseless electrical activity one month post-MV repair with posterior leaflet augmentation and CABG.
- Surgical findings revealed detachment of the autologous pericardial patch from the anterior papillary muscle.
- The patient presented with chest pain and severe MR, indicating acute valve dysfunction.
Findings:
- Patch detachment following posterior leaflet augmentation caused acute mitral regurgitation.
- Emergency reoperation was required due to the complication.
- Mitral valve replacement was ultimately performed.
Implications:
- This case highlights the risk of patch dehiscence after mitral valve repair.
- Avoiding tension focalization during posterior leaflet augmentation is critical for successful MV repair.
- Careful surgical technique can prevent severe complications like acute MR and hemodynamic instability.
