Key result
Pannus excision and removal of the artificial ring successfully reduced the mean trans-mitral pressure gradient from 10 mmHg to 3 mmHg in a patient with mitral stenosis after mitral valve plasty.

Reoperation with pannus resection and annuloplasty ring removal successfully treated late-onset mitral stenosis due to pannus formation after mitral valve plasty.
Single-case success with pannus resection suggests a feasible option; leaves open generalizability and need for prospective data.

Miyanaga et al. (2024) conducted a case report in Mitral stenosis due to pannus formation after mitral valve plasty (n=1). Pannus excision and removal of the artificial ring was evaluated on Mean trans-mitral pressure gradient. Pannus excision and removal of the artificial ring successfully reduced the mean trans-mitral pressure gradient from 10 mmHg to 3 mmHg in a patient with mitral stenosis after mitral valve plasty.
