A new technological system to revolutionize the management of valvular heart diseases: transcatheter aortic valve for the treatment of aortic stenosis [PDF]
arXiv, 2019 The goal of this study is a technology analysis of a revolution for the management of valvular heart diseases given by new technological system based on transcatheter artificial aortic valve, a delivery catheter and a loading system for the treatment of aortic stenosis (a narrowing of the aortic valve because of calcium build up that restricts blood ...

Immersed boundary-finite element model of fluid-structure interaction in the aortic root [PDF]
, 2015 It has long been recognized that aortic root elasticity helps to ensure efficient aortic valve closure, but our understanding of the functional importance of the elasticity and geometry of the aortic root continues to evolve as increasingly detailed in vivo imaging data become available.

Remote Ischemic Preconditioning Neither Improves Survival nor Reduces Myocardial or Kidney Injury in Patients Undergoing Transcatheter Aortic Valve Implantation (TAVI) [PDF]
, 2020 BACKGROUND: Peri-interventional myocardial injury occurs frequently during transcatheter aortic valve implantation (TAVI). We assessed the effect of remote ischemic preconditioning (RIPC) on myocardial injury, acute kidney injury (AKIN) and 6-month ...

Transcatheter Aortic Valve Replacement and Stroke [PDF]
Circulation: Cardiovascular Interventions, 2015 The evaluation of any therapy includes an assessment of benefits and risks. For percutaneous coronary interventions, death and myocardial infarction are typically selected as the 2 hard end points for describing adverse events. Stroke may be observed during percutaneous coronary intervention and be a direct result of the procedure.

Obstruction of 2 Coronary Arteries from Different Causes Immediately after Transapical Transcatheter Aortic Valve Replacement [PDF]
, 2020 Coronary obstruction, a rare complication of transcatheter aortic valve replacement, can be fatal. Few data exist on this phenomenon, and, to date, authors have reported only single coronary lesions.

Numerical investigation of the flow induced by a transcatheter intra-aortic entrainment pump [PDF]
Park Y. Numerical investigation of the flow induced by a
transcatheter intra-aortic entrainment pump (2025)This study evaluates the fluid dynamics inside and outside transcatheter blood pump positioned in the aorta. We focus on the pump's impact on blood component damage and arterial wall stress. CFD simulations were performed for rotational speeds ranging from 6000 to 15000 rpm, with a blood flow rate of 1.6 L/min.
