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)...

Transcatheter Aortic Valve Implantation (TAVI) is a well-described treatment for symptomatic calcific severe aortic stenosis. However, TAVI technology is being increasingly used around the world to treat selected cases of severe aortic regurgitation (AR). One of the main limitations of using TAVI technology for AR is the lack of calcification, which is common in such cases. This makes anchoring of a TAVI prosthesis to the aortic annulus difficult and risks displacement or embolization. However, with the availability of recapturable and repositionable TAVI technologies, these limitations have been overcome to a large extent...

AIMS: Transcatheter heart valve (THV) implantation in failed bioprosthetic valves (valve-in-valve [ViV]) offers an alternative therapy for high-risk patients. Elevated post-procedural gradients are a significant limitation of aortic ViV. Our objective was to assess the relationship between depth of implantation and haemodynamics. METHODS AND RESULTS: Commercially available THVs used for ViV were included in the analysis (CoreValve Evolut, SAPIEN XT and the Portico valve)...

REVIEW
Mike Saji, D Scott Lim
Following the first successful transcatheter aortic valve replacement (TAVR) in 2002, TAVR has globally evolved to become a standard procedure in high-risk patients. Surgical aortic valve replacement in non-high-risk patients remains the gold standard for treatment of severe aortic stenosis. However, a paradigm shift appears to be occurring in the direction of treating lower-risk patients, and several studies have suggested its impact on clinical outcomes. In this review, we highlight the current status of TAVR in intermediate-risk patients and review major trials including Placement of AoRTic TraNscathetER (PARTNER) 2A randomized intermediate-risk trial using SAPIEN XT (Edwards Lifesciences Corp, Irvine, CA) recently presented with excellent outcomes and the lowest major complications rate at the American College of Cardiology's 65th Annual Scientific Session in Chicago...

BACKGROUND: Transcatheter aortic valves can degenerate in a manner similar to surgical bioprostheses. METHODS AND RESULTS: Clinical and echocardiographic outcomes of patients who underwent redo transcatheter aortic valve replacement (TAVR) procedures >2 weeks post procedure were collected from 14 centers. Among 13 876 patients, 50 (0.4%) underwent redo TAVR procedure at participating centers. Indications for redo TAVR were moderate-severe prosthetic aortic valve stenosis (n=10, 21...

BACKGROUND: Redo surgery for degenerative bioprosthetic aortic valves is associated with significant morbidity and mortality. Report results of valve-in-valve therapy (ViV-TAVI) in failed supra-annular stentless Freedom Solo (FS) bioprostheses, which are the highest risk for coronary occlusion. METHODS: Six patients with FS valves (mean age 78.5 years, 50% males). Five had valvular restenosis (peak gradient 87.2 mm Hg, valve area 0.63 cm(2) ), one had severe regurgitation (AR)...

BACKGROUND: Transcatheter valve implantation inside failed bioprosthetic surgical valves (valve-in-valve [ViV]) may offer an advantage over reoperation. Supra-annular transcatheter valve position may be advantageous in achieving better hemodynamics after ViV. Our objective was to define targets for implantation that would improve hemodynamics after ViV. METHODS AND RESULTS: Cases from the Valve-in-Valve International Data (VIVID) registry were analyzed using centralized core laboratory assessment blinded to clinical events...

Balloon predilation is historically considered a requirement before performing transcatheter aortic valve implantation (TAVI). As the procedure has evolved, it has been questioned whether it is actually needed, but data are lacking on mid-term outcomes. The aim of this study was to evaluate the effect of balloon predilation before TAVI. A total of 517 patients who underwent transfemoral TAVI from November 2007 to October 2015 were analyzed. The devices implanted included the Medtronic CoreValve (n = 216), Medtronic Evolut R (n = 30), Edwards SAPIEN XT (n = 210), and Edwards SAPIEN 3 (n = 61)...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is the treatment of choice for high-risk patients presenting with severe symptomatic aortic stenosis. The aim of this study was to investigate the impact of second-generation (2G) devices in comparison to first-generation (1G) devices with regard to procedural and short-term clinical outcomes. METHODS: Between November 2007 and May 2015, a total of 449 patients treated with 1G TAVI devices (Edwards Sapien XT, Medtronic CoreValve) were propensity matched (1:1) to 179 patients treated with 2G TAVI devices (Edwards Sapien 3, Medtronic Evolut R, Boston Scientific Lotus, Direct Flow Medical)...

Transcatheter aortic valve implantation (TAVI) has been established as a therapeutic option in patients with a high procedural risk presenting with severe aortic stenosis. Recent improvements of TAVI technology made it possible to treat degenerated bioprosthesis using the valve-in-valve implantation concept. The self-expanding CoreValve (Medtronic, Minneapolis, MN) prosthesis has recently been redesigned and was introduced into clinical practice. We report a case of a not fully expanded Medtronic CoreValve Evolut R after deploying a 26 mm prosthesis into a degenerated 25 mm Carpentier-Edwards Perimount prosthesis...

Transcatheter aortic valve replacement remains challenge in patients with ball-cage-type mechanical valve in mitral position. Potential under-expansion of the percutaneous valve and interaction between the mitral ball-cage mechanical valve tilted towards the left ventricular outflow tract and the percutaneous valve adds risk during and after implantation. We report a successful implantation of the novel CoreValve Evolut-R self-expanding in a patient with severe aortic stenosis and a mitral Starr-Edwards mechanical valve implanted 28years ago...

The application of transcatheter aortic valve implantation (TAVI) in a wider and younger population in the near future makes the need to successfully deal with challenging procedural conditions an imperative. We report a case in which TAVI was successfully conducted in a patient with aortic coarctation using a last-generation low-profile bioprosthesis. Despite the fragile aortic wall and its possible abnormal function, a low-profile (14F) CoreValve Evolute R device (Medtronic, Minneapolis, MN) was implanted through the coarctation without complications...

OBJECTIVES: The purpose of this study was to prospectively evaluate the safety and clinical performance of the CoreValve Evolut R transcatheter aortic valve replacement (TAVR) system (Medtronic, Inc., Minneapolis, Minnesota) in a single-arm, multicenter pivotal study in high- or extreme-risk patients with symptomatic aortic valve stenosis. BACKGROUND: Although outcomes following TAVR are improving, challenges still exist. The repositionable 14-F equivalent CoreValve Evolut R TAVR system was developed to mitigate some of these challenges...
