چکیده
Abstract The Valve-in-Valve (ViV) technique is an emerging alternative for the treatment of bioprosthetic structural valve deterioration (SVD) in mitral position. We report on intermediate-term outcomes patients with symptomatic SVD position who were treated by transcatheter valve-in-valve (TM-ViV) implantation during years 2010–2019 our center. Three main examined follow-up period: NYHA functional class, TM-ViV hemodynamic data per echocardiography, and mortality. Our cohort consisted 49 (mean age 77.4±10.5 years, 65.3% female). indications mainly regurgitant pathology (77.6%). All a balloon-expandable device. procedure was performed via transapical access 17 cases (34.7%) transfemoral vein / trans-atrial septal puncture 32 (65.3%). Mean 4.4±2.0 years. 98% 91% I/II at 1 5 respectively. Mitral regurgitation ≥ moderate 86.3% prior to this decreased 0% (p<0.001) following maintained over 2 follow-up. mean trans-mitral gradients from pre-procedural values 10.1±5.1mmHg 7.0±2.4mmHg one month (p=0.03).

Transcatheter Mitral Valve Implantation
T he rationale for the development of a transcatheter mitral valve implantation (tMVI) procedure, either percutaneous or via minimally invasive surgery (MIS), arose from consideration of several key surgical concepts. First, mitral valve replacement is the most effective modality and the gold standard procedure for reliably reducing mitral regurgitation (MR). The efficacy and risks of mitral va...

A 73-year old man underwent trans-septal anterograde implantation of a 26-mm Sapien-XT valve (Edwards Lifesciences, CA, USA) to treat a degenerated 27-mm Carpentier-Edwards bioprosthesis. During the follow-up, the patient experienced severe haemolysis with moderate-to-severe inter-valvular leak, and fluoroscopy revealed possible incomplete apposition of the Sapien-XT (Fig. 1). Reoperation was p...
متن کاملEchocardiography in Transcatheter Aortic Valve Implantation and Mitral Valve Clip
Transcatheter aortic valve implantation and transcatheter mitral valve repair (MitraClip) procedures have been performed worldwide. In this paper, we review the use of two-dimensional and three-dimensional transesophageal echo for guiding transcatheter aortic valve replacement and mitral valve repair.
