Predicting LVOT Obstruction in Transcatheter Mitral Valve Implantation: Concept of the Neo-LVOT.
OUTFLOWTRACT OBSTRUCTION IS A FEAREDAND POTENTIALLY LETHAL COMPLICATION OF TRANSCATHETER mitral valve replacement (TMVR), mitral valve-in-valve (ViV), and valve-in-ring (ViR) procedures as well as implantation of transcatheter heart valves in calcific mitral valve disease. These procedures ultimately lead to elongation of the outflow tract into the left ventricle, whereas the pre-existing “nati...
متن کاملTranscatheter 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...
متن کاملFailed valve-in-valve transcatheter mitral valve implantation.
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 کاملThe HighLife transcatheter mitral valve implantation system.
Device description Name and manufacture: HighLife SAS, Paris, France. Approval status: Preclinical. Platform: Nitinol. Specific design: The HighLife transcatheter mitral valve replacement device is a two-component system (Figure 1). The valve prosthesis is implanted over a delivery system in the mitral position and is anchored by interacting and then reaching an equilibrium position with a prev...
متن کاملCoronary Obstruction Following Transcatheter Aortic Valve Implantation
BACKGROUND Transcatheter aortic valve implantation (TAVI) was established as an important alternative for high-risk patients with severe aortic stenosis. However, there are few data in the literature regarding coronary obstruction, that although rare, is a potentially fatal complication. OBJECTIVE Evaluate this complication in Brazil. METHODS We evaluated all patients presenting coronary ob...
