title: Transaortic Edge-to-Edge Repair for Functional Mitral Regurgitation During Aortic Valve Replacement: A 13-Year Experience.
abstract: OBJECTIVE
  The study evaluated the feasibility of a transaortic edge-to-edge mitral valve repair (Alfieri stitch) for moderate or greater (≥2+) functional mitral regurgitation (MR) in high-risk patients undergoing aortic valve replacement.
  
  
  METHODS
  We retrospectively evaluated 40 consecutive patients who underwent aortic valve replacement combined with a transaortic edge-to-edge mitral valve repair for 2+ or greater functional MR, between February 2002 and April 2015. The MR was graded semiquantitatively as 0 (trace/none), mild (1+), moderate (2+), or moderate to severe (3-4+).
  
  
  RESULTS
  Thirty-two patients had aortic stenosis, and eight had aortic regurgitation. The mean ± standard deviation (SD) age was 77.5 ± 5 years, 34 (85%) were male, and the mean ± SD EuroSCORE II was 14.3% ± 12.9. At a median follow-up of 1 month (interquartile range, 0.75-10), there were significant improvements in preoperative versus postoperative median MR grade (3+ vs 1+, P < 0.001), mean left ventricular ejection fraction (34% vs 41%, P = 0.018), left ventricular end-diastolic diameter (54 vs 49 mm, P = 0.005), and pulmonary artery systolic pressure (49 vs 35 mm Hg, P < 0.001). Persistent 3 to 4+ MR occurred in two patients (5%). In 12 patients with at least 6-month follow-up (mean ± SD, 18 ± 11 months), a sustained improvement in all echocardiographic parameters was observed, with persistent 3 to 4+ MR occurring in one patient (8.3%). Actuarial survival at 1, 3, and 4.5 years was 82% ± 6, 71% ± 8, and 65% ± 10, respectively.
  
  
  CONCLUSIONS
  A transaortic edge-to-edge repair for 2+ or greater functional MR can be safely performed during aortic valve replacement and is associated with improvements in MR grade, left ventricular remodeling, and pulmonary hemodynamics.
