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.
