Summary
Mitral valve repair using 3D transesophageal echocardiography (3DTEE) can virtually resect prolapsed leaflets. This technique effectively restores leaflet coaptation and reduces stress, optimizing mitral valve repair outcomes.
Area of Science:
- Cardiovascular Surgery
- Medical Imaging
- Biomedical Engineering
Background:
- Mitral valve (MV) leaflet prolapse often requires surgical repair.
- Partial leaflet resection and ring annuloplasty are established MV repair techniques.
Observation:
- A 61-year-old male presented with severe mitral regurgitation due to posterior leaflet prolapse.
- Three-dimensional transesophageal echocardiography (3DTEE) revealed significant leaflet malcoaptation and high stress concentration.
Findings:
- Virtual posterior leaflet resection and ring annuloplasty were performed using 3DTEE.
- The virtual repair successfully decreased prolapse, restored leaflet coaptation, and eliminated high stress areas.
Implications:
- 3DTEE-based virtual MV repair strategies can optimize surgical planning.
- This approach shows potential for improving the reliability and reproducibility of mitral valve repair.
