Transcatheter aortic valve implantation (TAVI) has become a safe and efficient alternative to cardiac surgery in patients with severe aortic stenosis. In many countries the number of performed TAVI procedures equals the number of surgical implantations. Indications for TAVI are becoming more liberal, allowing a wider spectrum of patients to benefit from the advantages of transcatheter therapy. ...

Transcatheter aortic valve implantation (TAVI) is a new method for patients with severe aortic stenosis at high surgical risk, such as previous cardiac surgery. The presence of mechanical mitral prosthesis might complicate TAVI because of possible interference between the both prosthesis. Some reports have already demonstrated the feasibility of TAVI in such patients. We report our experience w...

D uring the last decade, transcatheter aortic valve implantation (TAVI) has expanded the frontiers of interventional cardiology and gained a firm position in the therapeutic quiver for severe aortic stenosis. While the TAVI boom already amounts to more than 100,000 procedures worldwide,1 its recent (2014) inclusion in the American Heart Association/American College of Cardiology guidelines for ...

During the past years transcatheter aortic valve implantation (TAVI) has evolved to a standard technique for the treatment of high risk patients suffering from severe aortic stenosis. Worldwide the number of TAVI procedures is increasing exponentially. In this context both the transapical antegrade (TA) and the transfemoral retrograde (TF) approach are predominantly used and can be considered a...

Introduction The "transfemoral (TF) first" approach to access route selection in transcatheter aortic valve implantation (TAVI) is popular; however, the risk of major vascular complications is substantial. The "best for TF" approach identifies only the patients with ideal anatomy for TF-TAVI, potentially minimizing complications. Aim To characterize the outcomes of patients undergoing TAVI at...

BACKGROUND In patients with severe calcific aortic stenosis, balloon aortic valvuloplasty (BAV) is routinely performed in order to pre-dilate the stenosed aortic valve prior to transcatheter aortic valve implantation (TAVI). Although pre-dilation is considered to be essential for the preparation of the valve landing zone, there is no clear evidence to support its clinical value. In contrast, BA...

BACKGROUND AND OBJECTIVES Periprosthetic aortic regurgitation (PPR) after transcatheter aortic valve implantation (TAVI) remains an important issue associated with impaired long-term outcomes. The current randomised study aims to evaluate potential differences between the balloon-expandable Edwards SAPIEN-3 and the self-expanding Medtronic CoreValve system with the main focus on post-TAVI PPR b...

OBJECTIVES Deciding on the optimal treatment strategy for high risk aortic valve replacement is challenging. Transcatheter Aortic Valve implantation (TAVI) has been available in our centre as an alternative treatment modality for patients since 2008. We present our early experience of TAVI and SAVR (surgical Aortic Valve Replacement) in high risk patients who required SAVR because TAVI could no...

Aortic valve replacement (AVR) is a treatment of choice for patients with symptomatic severe aortic stenosis (AS). However, a significant proportion of these patients do not undergo surgical AVR due to high-risk features. Transcatheter aortic valve implantation (TAVI) has emerged as an alternative for patients with severe AS who are not candidates for open-heart surgery. Since the introduction ...

AIMS To date every post-procedural cerebrovascular embolic event (CVE) is dreaded for its potential to accelerate cognitive decline after transcatheter aortic valve implantation (TAVI). This study differentiates the impact of acute (procedural) and post-acute cerebrovascular embolic events (CVEs) on cognitive performance. METHODS Magnetic resonance imaging (MRI) before, early and late after T...
