Overview

Highlights gaps in rheumatic mitral surgery planning; leaves open validation of predictive models and prosthesis-specific data.

Structured PICO

P
Population
Patients with severe rheumatic mitral stenosis with more than mild regurgitation
I
Intervention
Mitral valve repair
C
Comparator
Mitral valve replacement
O
Outcome
Midterm survival

This letter emphasizes the importance of detailed anatomical mapping, prosthesis differentiation, and mechanistic subtyping to improve personalized surgical planning in rheumatic mitral valve disease.

Limitations

  • Lack of a formal risk model for postoperative residual or recurrent regurgitation
  • Failure to differentiate prosthesis type or anticoagulation-related outcomes
  • Lack of detailed analysis of calcification patterns
  • Failure to clarify mechanism-based subgroups of regurgitation
