- W3200971520 abstract "Abstract Background Percutaneous mitral valve (MV) clipping for mitral regurgitation (MR) revolutionized MV repair; however, valve anatomies and pathologies vary. Often multiple clips are required, and predicting this pre-procedurally would be useful. We evaluated pre-procedural predictors for multiple clips. Results We retrospectively analyzed 127 severe MR patients treated by mitral clipping between January 2011 and August 2018. Patients were grouped according to the use of a single (group I) or multiple clips (group II) and pre-procedure echocardiographs compared. No demographic differences existed except group II had more males (68.1%) than group I (48.3%). Mean left atrial diameter was larger in group II, 51 ± 9 mm, than group I, 48 ± 5 mm, p = 0.026. Mean mitral annular diameter differed: 34 ± 4mm (group II) versus 33 ± 3 mm (group I), p = 0.017. The vena contracta was broader in group II than group I (6.6 ± 1 mm vs. 6 ± 0.9 mm, p = 0.001). Severe mitral annular calcification occurred more in group I (36.2%) than group II (10.1%), p = 0.0001. On multivariate analysis, vena contracta width correlated positively with multiple clips ( B 0.125, p = 0.013), but severe annular calcification correlated inversely ( B − 0.35, p = 0.002). Conclusions Vena contracta width and severe annular calcification are factors to consider when planning MV clipping." @default.
