AIMS: This analysis evaluated the incidence and predictors of the need for permanent pacemaker (PPM) implantation following implantation of the repositionable and fully retrievable Lotus Aortic Valve Replacement System. METHODS & RESULTS: The prospective, single arm, multicentre REPRISE II study with extended cohort enrolled 250 symptomatic, high surgical risk patients with severe aortic stenosis for transfemoral transcatheter aortic valve implantation (TAVI) with a 23mm or 27mm Lotus Valve...

Transcatheter aortic valve implantation (TAVI) is a validated technique for the treatment of aortic valve stenosis in patients with high surgical risk or inoperable. We present the case of an 80-year-old woman with severe aortic valve stenosis (mean gradient 55 mmHg), mild surgical risk, who refused traditional surgery. We implanted a Lotus Sadra 25 mm (Boston Scientific, Marlborough, MA, USA) via the transfemoral route. During pull back delivery, the patient experienced interscapular pain with angiographic evidence of type B aortic dissection effectively treated by implanting a vascular endoprosthesis Valiant 30 x 150 mm (Medtronic Vascular, Santa Rosa, CA, USA)...

OBJECTIVES: A transcatheter heart valve technique can be used in failed mitral valve repairs with annuloplasty rings, deterioriated bioprostheses and in mitral annular calcification, all serving as 'docking stations' for balloon-expandable valves. Specially designed transcatheter mitral valve platforms are used in ongoing studies for native mitral valve regurgitation. We present our single centre experience with transcatheter mitral valve implantation-transapical approach procedures in eleven patients...

Transcatheter aortic valve implantation (TAVI) has become the standard treatment for aortic stenosis in high-risk patients. TAVI for native valve aortic regurgitation is technically more demanding because of a lack of anchoring calcification, a lower index incidence, heterogeneous causes, and larger anatomy. We present 3 cases in which the Lotus TAV was used to treat severe native aortic regurgitation (AR) successfully.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic valve stenosis (AS) is being increasingly performed. OBJECTIVES: From the Bicuspid AS TAVR multicenter registry, the procedural and clinical outcomes in patients with bicuspid versus tricuspid AS were compared. METHODS: Outcomes of 561 patients with bicuspid AS and 4,546 patients with tricuspid AS were compared after propensity-score matching assembling 546 pairs of patients with similar baseline characteristics...

OBJECTIVES: : The aim of this study was to prove technical feasibility and document haemodynamic and clinical outcomes of transcatheter aortic valve implantation (TAVI) with the latest generation repositionable and retrievable Lotus™ transcatheter heart valve (THV) without prior balloon-aortic valvuloplasty (BAV). It has been demonstrated for self-expandable and balloon-expandable THV that implantation without prior BAV is not only feasible and safe but also results in lower fluoroscopy times and amounts of contrast agent while yielding non-inferior haemodynamic and clinical outcome...

BACKGROUND: Right bundle branch block is an established predictor for new conduction disturbances and need for a permanent pacemaker (PPM) after transcatheter aortic valve replacement. The aim of the study was to evaluate the absolute rates of transcatheter aortic valve replacement related PPM implantations in patients with pre-existent right bundle branch block and categorize for different transcatheter heart valves. METHODS AND RESULTS: We pooled data on 306 transcatheter aortic valve replacement patients from 4 high-volume centers in Europe and selected those with right bundle branch block at baseline without a previously implanted PPM...

BACKGROUND: Conduction disturbances requiring permanent pacemaker implantation following transcatheter aortic valve replacement (TAVR) are a common problem. Pacemaker implantation rates after TAVR appear to be higher compared to conventional aortic valve replacement. The aim of this study was to analyze whether a high annulus implantation conveys the benefit of a decreased rate of permanent pacemaker implantation while being safe and successful according to VAR2-criteria. METHODS: A total of 23 patients with symptomatic severe aortic valve stenosis, an aortic annulus of 19-27mm and at high risk for surgery were treated with the Lotus valve...

BACKGROUND: Patients with failed bioprostheses are an increasing population at high risk for redo surgery. Valve-in-valve transcatheter aortic valve implantation is a promising alternative but a limited number of first-generation devices have proven efficacy in all cases. METHODS: Patients with degenerated bioprostheses at high risk for redo surgery were included in the registry after being assigned to valve-in-valve intervention by a local heart team. Main basal and follow-up data (at 1 month and 6 months) of patients undergoing valve-in-valve transcatheter aortic valve implantation with the Lotus valve system (Boston Scientific, Natick, MA) in three high-volume Italian centers were entered in the registry...

BACKGROUND: In the evolving field of transcatheter aortic valve replacements a new generation of valves have been introduced to clinical practice. With the complexity of the TAVR procedure and the unique aspects of each TAVR device, there is a perceived risk that changing or adding a new valve in a department could lead to a worse outcome for patients, especially during the learning phase. The objective was to study the safety aspect of introducing a second generation repositionable transcatheter valve (Boston Scientific Lotus valve besides Edwards Sapien valve) in a department...

AIMS: The Lotus and SAPIEN3 are second-generation transcatheter heart valves, which are designed to minimize paravalvular aortic regurgitation (PAR) after transcatheter aortic valve replacement (TAVR). We sought to compare both devices for valve performance and with emphasis on PAR by independent core laboratory analysis. METHODS AND RESULTS: A total of 162 (79 Lotus and 83 SAPIEN3) consecutive patients (51% female, 80 ± 8 years, Logistic EuroSCORE 14.8 ± 9...

OBJECTIVE: To determine the safety and efficacy of valve repositioning following transcatheter aortic valve replacement (TAVR) with the Lotus Valve System (Boston Scientific, Marlborough, MA, USA). INTRODUCTION: TAVR is a well-established treatment for severe aortic stenosis. The Lotus Valve System is fully repositionable and retrievable. Valve repositioning has the potential to minimize TAVR-related complications caused by valve malposition; however, the effect on adverse event rates such as stroke is unknown...

OBJECTIVES: To determine the incidence and predictors of permanent pacemaker (PPM) requirement following transcatheter aortic valve replacement (TAVR) with the mechanically expanded Lotus(TM) Valve System (Boston Scientific). BACKGROUND: Pacemaker implantation is the most common complication following TAVR. Predictors of pacing following TAVR with the Lotus valve have not been systematically assessed. METHODS: Consecutive patients with severe aortic stenosis who underwent Lotus valve implantation were prospectively recruited at a single-centre...
