Synthetic chordae used in mitral valve repair for rheumatic disease become indistinguishable from native tissue over time due to fibrosis. This long-term tissue integration offers a promising outlook for artificial chordae durability in mitral valve surgery.

Area of Science:

  • Cardiovascular Surgery
  • Biomaterials Science
  • Rheumatic Heart Disease

Background:

  • Presents a case study of mitral valve repair using synthetic chordae for rheumatic disease.
  • Follows a patient 13 years post-operative repair.

Observation:

  • Examined a previously repaired mitral valve using artificial chordae tendinae.
  • Utilized echocardiographic, pathologic, and histologic methods for assessment.

Findings:

  • Extensive fibrosis and thickening observed around the artificial chorda.
  • Fibroblasts and mature collagen integrated with the synthetic material.
  • Artificial chordae became indistinguishable from native tissue on gross and echocardiographic examination.

Implications:
