Summary

Mitral valve repair for congenital malformations offers good survival rates. However, associated heart defects significantly impact outcomes, increasing mortality and reoperation risk.

Area of Science:

  • Cardiovascular Surgery
  • Pediatric Cardiology
  • Congenital Heart Defects

Background:

  • Mitral valve congenital malformation (MVCM) can occur in isolation or with other cardiac defects.
  • Understanding outcomes and predictors of poor results in MVCM patients is crucial.

Purpose of the Study:

  • To evaluate early and mid-term survival and reoperation rates in children with MVCM.
  • To identify predictors for adverse outcomes in patients undergoing mitral valve repair.

Main Methods:

  • Retrospective analysis of 58 children with MVCM undergoing mitral valve-conserving surgery (1990-2001).
  • Patients divided into isolated MVCM (Group I) and MVCM with associated congenital heart defects (ACHD) (Group II).
  • Analysis of surgical techniques, ventilation time, postoperative mitral regurgitation, survival, and reoperation rates.

Main Results:

  • Hospital mortality was 5% in Group I and 13% in Group II.
  • Five-year actuarial survival was 91.5% (Group I) and 86% (Group II); reoperation-free survival was 85% (Group I) and 73% (Group II).
  • Predictors for poor event-free survival included age >12 months, hammock MV, and ACHD.

Conclusions:

  • Mitral valve repair for MVCM yields acceptable early and mid-term survival and reoperation-free rates.
  • Associated congenital heart defects significantly diminish both early and late postoperative survival and freedom from reoperation.
