Minimally Invasive Mitral Valve Repair or Replacement for Degenerative Mitral Regurgitation

Hata and colleagues performed a propensity score-matched analysis comparing 85 pairs of patients who underwent either minimally invasive mitral valve repair or chordal-sparing replacement for degenerative mitral valve regurgitation. Freedom from major adverse cardiac and cerebrovascular events after seven years was similar between the groups. There was no difference in mortality and no difference in freedom from valve reintervention.
