Abstract:
A 57-year-old man suffered recurrent mitral regurgitation after dehiscence of a 28 mm Physio ring 3 months after initial repair. We substituted a 30 mm Physio ring in reoperation, enabling successful mitral rerepair. This case points up the need for special care to be taken in determining the size of rigid rings and suture placement deep enough in annular tissue.
Insights
Mitral regurgitation recurrence after ring dehiscence necessitates careful ring sizing and suture placement during mitral valve repair. A larger ring and deep sutures ensured successful reoperation in this case.
Area of Science:
- Cardiovascular Surgery
- Cardiac Valve Repair
- Medical Device Technology
Background:
- Mitral regurgitation is a common valvular heart disease.
- Ring dehiscence can lead to recurrent mitral regurgitation after repair.
- Physio rings are used in mitral valve repair procedures.
Observation:
- A 57-year-old male patient presented with recurrent mitral regurgitation 3 months post-mitral valve repair.
- The initial repair involved a 28 mm Physio ring, which dehisced.
- The patient underwent reoperation for mitral valve rerepair.
Findings:
- A larger 30 mm Physio ring was successfully implanted during reoperation.
- The mitral valve rerepair was technically successful, resolving the regurgitation.
- Histopathological examination of the explanted ring and surrounding tissue was not performed in this case.
Implications:
- This case underscores the critical importance of accurate sizing of rigid annuloplasty rings.
- Proper suture technique, ensuring deep placement within the annular tissue, is crucial for device fixation.
- Careful consideration of ring material properties and annular tissue integrity is necessary to prevent dehiscence and ensure long-term repair durability.
