网页Flail Mitral Valve. Failure of leaflets coaptation with rapid systolic movement of the involved leaflet into the left atrium, due to rupture chordae tendineae or papillary muscle. May result in acute, subacute or chronic MR.
Not All Flails Are Created Equal - Journal of the American College …
网页2021年12月1日 — Flail Gap and Flail Width. Schematic depicting a mitral flail gap and the flail width. What are the implications of this study? The presence of a flail or eccentric wall-hugging jet, in isolation, should not be interpreted as indicating severe MR.
Echocardiographic evaluation and guidance for MitraClip procedure
网页2017年7月4日 — Flail mitral leaflets should be evaluated for the degree of mobility and the maximal flail gap distance measured to determine if successful grasping will be possible (ideally flail width <15 mm and flail gap <10 mm).
Transesophageal Echocardiography During MitraClip
网页For patients with a flail mitral leaflet, a flail gap <10 mm and a flail width <15 mm are also important anatomic features to allow proper grasping. Flail gap is defined as the greatest distance between the ventricular side of the flail segment to the atrial side of the opposing leaflet edge in either the 4-chamber LAX or ME LAX view ( Fig. 2C ).
网页For DMR the flail gap should be less than 10 mm and the flail width <15 mm. In addition, severe bileaflet prolapse or bileaflet flail was considered a contraindication for MitraClip therapy. For FMR the coaptation depth should be <11 mm and the coaptation length ≥2 mm.
网页– LV size and function • COAPT and MITRA -FR provide important information to help us understand which SMR patients are good and poor candidates for MitraClip . • To duplicate the COAPT results, specific COAPT screening echo criteria and expert echo analysis should be applied to identify proper candidates for MitraClip .
Imaging in MV Interventions: MitraClip and Beyond...
网页2018年8月6日 — For patients with a flail leaflet, the width of the flail segment must be <15 mm, and the flail gap must be <10 mm. Lastly, the LV ejection fraction must be >25%, and the LV end-systolic diameter must be ≤5.5 cm. 9
Peri-interventional echo assessment for the MitraClip procedure
网页2013年10月1日 — In degenerative disease, an excessive flail width and an excessive flail gap should be excluded. Further, some residual coaptation length should exist in functional MR. The MV area (MVA) before a procedure should not be less than 4 cm² in order to avoid creating a stenotic MV post procedure.

网页2021年10月1日 — The landmark EVEREST (Endovascular Valve Edge-to-Edge Repair Study) and COAPT (Clinical Outcomes Assessment of the MitraClip Percutaneous Therapy for High Surgical Risk Patients) trials included only clinically stable patients with favorable mitral valve anatomy for edge-to-edge repair.

网页2020年1月23日 — Given the fixed arm length, the ideal anatomy for successful grasping has included a flail width of <15 mm and a flail gap of <10 mm. Until recently, patients with more extreme anatomy with very large flail gaps may not be offered transcatheter repair due to potential inability to grasp the leaflets.
