- W2785109077 abstract "Background The transapical echo-guided NeoChord repair is a procedure to correct mitral regurgitation (MR) without the need for concomitant annuloplasty for degenerative mitral valve (MV) disease. Lacking strict criteria to define normal annular dimensions for patients undergoing MV repair, we consequently missed having precise selection criteria to identify patients who can benefit from a ringless procedure with respect to who would need a combined annular and leaflet repair. The aim of this study is to identify whether a new preoperative echocardiographic index may predict postoperative outcomes after NeoChord repair. Methods All consecutive patients with posterior leaflet disease who underwent NeoChord repair between November 2013 and January 2016 presenting complete postoperative echocardiographic assessment up to 1 year were included. Leaflet-to-Annulus Index (LAI) was defined as the ratio between the sum of anterior leaflet length (AML) and posterior leaflet length (PML) over antero-posterior length (AP; AML + PML/AP). Measurements were performed with 2D transesophageal echocardiography. Results Sixty-six patients were enrolled. At 1 year MR was absent in (24) 38% of patients, mild in (28) 44%, moderate in (10) 16% and severe in (1) 2%. Logistic regression analysis identified LAI as positive prognostic predictor of MR ≤ mild for values >1.35 at 3 months, 1.30 at 6 months and 1.25 at 1 year. At 30 days LAI was not associated with the grade of residual MR. Conclusions LAI is a positive postoperative predictor of MR ≤ mild at 1-year follow-up and can be used to identify patients who could benefit from a ringless NeoChord repair procedure for the absence of a leaflet-to-annulus mismatch." @default.
