Patient-specific finite element analysis of transcatheter aortic valve implantation
Aortic valve stenosis represents an important public health problem which can be treated through transcatheter aortic valve implantation. Being a quite recent technology, many aspects related to such a minimallyinvasive procedure need further investigation (e.g., paravalvular leakage). The well-established finite element method represents a possible technology to study such aspects within a vir...
متن کاملReview of patient-specific simulations of transcatheter aortic valve implantation
Transcatheter Aortic Valve Implantation (TAVI) accounts for one of the most promising new cardiovascular procedures. This minimally invasive technique is still at its early stage and is constantly developing thanks to imaging techniques, computer science, biomechanics and technologies of prosthesis and delivery tools. As a result, patient-specific simulation can find an exciting playground in T...
متن کاملSimulation of transcatheter aortic valve implantation: a patient-specific finite element approach.
Until recently, heart valve failure has been treated adopting open-heart surgical techniques and cardiopulmonary bypass. However, over the last decade, minimally invasive procedures have been developed to avoid high risks associated with conventional open-chest valve replacement techniques. Such a recent and innovative procedure represents an optimal field for conducting investigations through ...
متن کاملCerebral embolization during transcatheter aortic valve implantation.
The recent success of transcatheter aortic valve implantation (TAVI) has been associated with a heightened awareness of the potential risks, particularly stroke. Recent meta-analyses report 30-day stroke rates of 3% to 4%,1,2 and diffusion-weighted MRI studies have revealed new, clinically silent, cerebral lesions in 68% to 84% of patients undergoing TAVI.3–5 Although the majority of patients u...
متن کاملTranscatheter Aortic Valve Implantation
A 97-year-old man was referred for assessment to our transcather aortic valve implantation (TAVI) team. He had suffered multiple hospitalizations for heart failure with a signifi cantly elevated BNP at 1830 pg/mL. At the time of assessment, he had grade IV New York Heart Association (NYHA) symptoms. Until recently, he had been working actively, but this had subsequently been severely limited by...
