AB  - OBJECTIVE: Mitral subvalvular procedures in addition to restrictive annuloplasty 
      are promising for ischemic mitral regurgitation (IMR). However, the prevalence 
      and efficacy of specific subvalvular repair in severe IMR have not been 
      elucidated. This is the first nationwide survey regarding surgeons' attitudes 
      toward IMR in Japan. METHODS: A questionnaire was sent to 543 institutions. From 
      2015 to 2019, numbers of elective first-time mitral valve replacement (MVR) 
      with/without complete chordal preservation (CCP)/papillary muscle approximation 
      (PMA) and mitral valvuloplasty (MVP) with/without papillary muscle relocation 
      (PMR)/PMA in patients with severe IMR were collected. Concomitant procedures for 
      coronary artery, tricuspid valve, and arrhythmia could be included but left 
      ventricular reconstruction was excluded. RESULTS: Completed questionnaires were 
      received from 286 institutions (52.7%). The majority (90%) had less than 20 cases 
      within 5 years. The number of MVP (1413, 61.5%) surpassed MVR (886, 38.5%). CCP 
      was performed in half of MVR (50.0%), while PMA was included in only 1.9% of MVR. 
      PMA and PMR were also performed infrequently, in only 7.7% and 10.9% of MVP, 
      respectively. CONCLUSION: Japanese surgeons aggressively perform MVP for severe 
      IMR. Subvalvular repair was also aggressively performed in addition to MVR, but 
      not to MVP. A multicenter registry study is in progress.
