Direct Endoscopic Visual Assessment of a Transcatheter Aortic Valve Implantation and Performance in the PhysioHeart, an Isolated Working Heart Platform

摘要: Transcatheter aortic valve implantation (TAVI) is an increasingly considered option to treat stenosis in patients with a high operative risk. Valve placement during the procedure typically guided by angiography and/or echocardiography, whereas these techniques are also used judge valvular function. More detailed postprocedure visualization may be obtained 3-dimensional echocardiography or magnetic resonance imaging. These imaging methods appear adequate for clinical assessment of TAVI, but direct optical temporal and spatial resolution would advantageous study details this new procedure. The working heart model as described Chinchoy et al1 enables intracardiac endoscopy,2 which provides unique insights into form, function, physiology heart. We applied approach performance …
