PURPOSE OF REVIEW: The goal of this review is to summarize the current evidence supporting the use of transcatheter aortic valve implantation (TAVI) in high and intermediate-risk patients. The focus is on the five randomized controlled trials comparing TAVI with surgical aortic valve replacement (SAVR) published to date, as well as two recent meta-analyses. RECENT FINDINGS: TAVI has profoundly transformed the treatment of elderly patients presenting with symptomatic severe aortic stenosis...

OBJECTIVES: To evaluate the feasibility of coronary procedures after transcatheter aortic valve implantation (TAVI) with the CoreValve™ device. BACKGROUND: Due to its design, CoreValve™ prosthesis may interfere with coronary procedures. Data on this issue are sparse. METHODS: Between 2007 and 2015, 550 patients underwent CoreValve™ TAVI in our hospital. Among them, 16 underwent coronary angiogram after TAVI and were included in our retrospective study...

AIMS: Data on procedural and clinical outcomes after transcatheter aortic valve implantation (TAVI) with the new generation self-expanding Medtronic Evolut-R prosthesis in comparison with its predecessor, the Medtronic CoreValve, are scarce. METHODS AND RESULTS: In a nationwide, prospective, multi-center cohort study outcomes of consecutive transfemoral TAVI patients treated with the new- generation Medtronic Evolut-R (September 2014 - February 2016) and the Medtronic CoreValve (February 2011 - February 2016) were investigated...

INTRODUCTION AND OBJECTIVES: There are scarce clinical outcomes data on the new generation recapturable and repositionable CoreValve Evolut R. METHODS: Data on all-comer patients undergoing transcatheter aortic valve implantation (TAVI) with the Evolut R for severe symptomatic aortic stenosis at a single center were prospectively collected between February 2015 and April 2016. Clinical endpoints were independently adjudicated according to the Valve Academic Research Consortium-2 criteria...

OBJECTIVE: We sought to compare the new transcatheter aortic valve replacement (TAVR) device ACURATE neo (ACT) with the already established CoreValve (MCV) and SAPIEN XT (SXT) for the treatment of severe aortic stenosis (AS). BACKGROUND: Very few data on TAVR devices are available beyond MCV and SAPIEN and there is no previous study comparing ACT with MCV and SXT. METHODS: We prospectively evaluated consecutive patients who underwent transfemoral TAVR for the treatment of severe AS...

This study presents the in vitro hydrodynamic assessment of the TRISKELE, a new system suitable for transcatheter aortic valve implantation (TAVI), aiming to mitigate the procedural challenges experienced with current technologies. The TRISKELE valve comprises three polymeric leaflet and an adaptive sealing cuff, supported by a novel fully retrievable self-expanding nitinol wire frame. Valve prototypes were manufactured in three sizes of 23, 26, and 29 mm by automated dip-coating of a biostable polymer, and tested in a hydrodynamic bench setup in mock aortic roots of 21, 23, 25, and 27 mm annulus, and compared to two reference valves suitable for equivalent implantation ranges: Edwards SAPIEN XT and Medtronic CoreValve...

BACKGROUND: A major drawback of the transcatheter aortic valve replacement (TAVR) procedure using the self-expandable Medtronic CoreValve (MCV) prosthesis is the high incidence of conduction disturbances and the need for postprocedural permanent pacemaker (PPM) implantation. The depth of prosthesis implantation may be an important contributing factor. The study aim was to determine the relationship between angiographic measurements of the MCV prosthesis depth and the occurrence of new conduction disturbances and need for PPM after TAVR...

BACKGROUND: Aortic regurgitation (AR) is a frequent and life-limiting complication after transcatheter aortic valve implantation (TAVI). The study aim was to relate post-TAVI AR, using a self-expandable stent, to detailed baseline anatomical and morphological characteristics of the native aortic valve. METHODS: A total of 82 patients (40 males, 42 females; mean age 80 ± 7 years) who received a Medtronic CoreValve implant was included. Aortic root morphology, aortic annulus and implant size mismatch, implant position, extent of aortic annulus and leaflet calcification, the connected sub-annular calcification volume, and their distribution were quantified based on computed tomography scan analysis...

BACKGROUND: Although the efficacy and safety of transfemoral transcatheter aortic valve implantation (TAVI) have been improved with new devices, careful patient selection is essential and awkward complications associated with the procedure persist. Despite a gradual reduction in the delivery system size and the development of access site arterial closure devices, vascular complications remain one of the main challenges of TAVI. The aim of this single-center study was to prospectively evaluate the incidence and predictors of vascular complications in transfemoral TAVI...

BACKGROUND: The echocardiographic grading of paravalvular aortic leakage (PVL) after transcatheter aortic valve implantation (TAVI) severity is challenging. The study aim was to assess the value of quantitative Doppler echocardiography to monitor PVL severity. METHODS: A total of 100 subjects was enrolled in the study, including 65 consecutive patients who had undergone TAVI with a CoreValve prosthesis and without valvular aortic regurgitation, and 35 normal controls...

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 by means of novel imaging endpoints, and an additional focus on other clinical endpoints. ENDPOINTS: The primary endpoint of this study is quantitative assessment of the severity of post-procedural PPR using cardiac magnetic resonance imaging...

OBJECTIVE: Transcatheter aortic valve implantation (TAVI) has been adopted rapidly in Europe. TAVI national registries can augment understanding of technologies and represent real-world experience, providing further clinical insights. We undertook a meta-analysis of published European national TAVI registries to assess current results following TAVI in Europe. METHODS: Electronic databases were searched. The review focused on the comparison of the following TAVI strategies: transfemoral (TF) and transapical (TA) SAPIEN and CoreValve implantation...

OBJECTIVES: In this study, we compare procedural results of our first Evolut R (Medtronic, Minneapolis, MN, USA) implantations with the last CoreValve implantations. Main endpoints include paravalvular regurgitation, major vascular complications, stroke, and pacemaker implantation. BACKGROUND: The evolution of transcatheter aortic valve replacement (TAVR) was possible due to various technical improvements, leading to better periprocedural and long-term outcome. The newly designed Evolut R valve has the potential to further improve TAVR's performance...

Transcatheter aortic valves have been designed to treat high-risk surgical candidates affected by severe aortic stenosis, but little is known about the use of transcatheter valves in patients with severe pure aortic regurgitation. We describe the implantation of Medtronic CoreValve Evolut R (Medtronic, Minneapolis, MN) to treat an 82-year-old patient affected by severe pure aortic regurgitation who underwent prior mitral valve replacement with a biological valve protruding into the left ventricular outflow tract...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) has become the standard therapy for patients with severe symptomatic aortic stenosis and unacceptable high risk for surgical aortic valve replacement. Several different devices for TAVR have been introduced so far, each of them with unique features. AIMS: To analyze our first real-world experience with the second- generation, mechanically expanded, fully repositionable transfemoral Lotus TAVR device (Boston Scientific)...
