Impact of mitral annular calcification in mitral valve surgery: 25-year Mayo Clinic experience.

ABSTRACT:

Background

Annular calcification [mitral annular calcification (MAC)] may complicate mitral valve (MV) surgery, and long‑term outcome data are limited.

Methods

We reviewed adult patients undergoing MV surgery at our Clinic between January 2000 and December 2024. MAC was identified on preoperative imaging, and operative strategy prioritized repair when feasible and employed conservative debridement when necessary. Patients with MAC were matched 1:1 with patients without MAC using a propensity score.

Results

Among 11,350 MV operations with or without concomitant procedures, 1,603 patients (14.1%) had MAC, the median age was 72.6 years [interquartile range (IQR), 65.3-78.6 years], 54.8% were female. In the MAC cohort, 21% of patients had a prior sternotomy. Concomitant a
