Figure 1. Anatomic predictors for procedural success and failure after TMVr. A: flail scallop is associated with worse hemodynamic success after TMVr in primary mitral regurgitation patients; B: A single or multiple jets originating from one flail scallop are associated with hemodynamic success after TMVr; lower tenting volume (C) and tenting height (D) are associated with optimal MR reduction; E: low mitral valve leaflet-to-annulus index predicts residual MR; F: increasing annular height predicts optimal MR reduction. A: anterior; P: posterior; AL: anterolateral; PM: posteromedial; Ao: aortic valve; PML: posterior mitral valve leaflet; AML: anterior mitral valve leaflet; TMVr: transcatheter mitral valve edge-to-edge repair; MR: mitral regurgitation
