Abstract 13699: A True World Picture - Surgical Revision After Percutaneous Mitral Valve Repair With the Mitraclip Device
Background: Transcatheter mitral valve (MV) repair is of increasing interest facing however questionable mid term results. We herein report MV reference center experience of 18 patients who underwent MV surgery after failed percutaneous MV repair with MitraClip device (Evalve, Menlo Park, CA).
Methods: Between June 2010 and October 2013, a total of 141 patients with severe mitral regurgitation (MR) underwent MitraClip procedure at Heart Center Leipzig. 11 patients (7.8%) needed surgical treatment for failed MV repair with the MitraClip device. For the same reasons we admitted 7 patients who underwent MitraClip procedure in other cardiac surgery centers. Mean EuroScore II of the patients was 23,51 (5,17-60,14).
Results: From the group of 18 patients undergoing surgical treatment after MitraClip repair, 14 patients (77.7%) received one or more clip-implants and 4 patients (22.2%) suffered from failed MitraClip implantation. All patient were symptomatic (n=9, 50% - NYHA III; n=9, 50% - NYHA IV).
The primary indications for surgery were: partial clip detachment (n=11, 61.1%), failed MitraClip implantation (n=4, 22.2%), recurrent MR greater than moderate (2+) (n=3, 16.6%), acute mitral valve endocarditis (n=1, 5.5%), mitral ring and clip detachment (n=1, 5.5%). 13 patients (72.2%) underwent MV replacement, 3 patients (16.6%) received left-ventricular assist device (LVAD), 2 patients (11.1%) underwent MV repair.
One-month mortality reached 27,8% (n=5), and the overall mortality reached 50% (n=9).
Conclusions: MV repair was feasible in only 2 cases (11.1%). Despite the high operative risk, surgical treatment after percutaneous MV repair failure with the MitraClip device is an option to be considered.
