OBJECTIVES: The aim of this post hoc analysis from the RESPOND (Repositionable Lotus Valve System-Post-Market Evaluation of Real World Clinical Outcomes) post-market study was to assess the final implantation depth on the contrast aortogram after Lotus valve (Boston Scientific, Marlborough, Massachusetts) transcatheter aortic valve replacement (TAVR) and to correlate with permanent pacemaker implantation (PPI) and paravalvular leak (PVL). BACKGROUND: Contrast aortography allows for the assessment of implantation depth and PVL during and after TAVR...

OBJECTIVES: To determine permanent pacemaker (PPM) dependency following transcatheter aortic valve replacement (TAVR) with the Lotus™ valve system (Boston Scientific), and the impact of PPM implantation on long-term morbidity and mortality. BACKGROUND: Conduction abnormalities are among the most common complications following TAVR. Limited studies have assessed pacing dependency following TAVR. METHODS: Consecutive patients (n = 166) with severe aortic stenosis who underwent TAVR with the Lotus valve system were prospectively recruited from a single-center...

OBJECTIVE: To determine the effect of aorto-ventricular angulation (AA) on procedural success with the Lotus Valve system. BACKGROUND: AA, the angulation of the aortic valve basal plane, may affect the deployment of transcatheter aortic valve replacements (TAVRs). The Lotus Valve system is fully repositionable and delivered on a pre-shaped catheter which may alter the impact of AA on its deployment. The effect of AA on procedural and clinical outcomes with the Lotus valve is unreported...

BACKGROUND / PURPOSE: The Lotus valve (Boston Scientific, Natick, MA, USA) is a contemporary transcatheter aortic valve implantation (TAVI) device that is fully repositionable and retrievable to aid implantation and optimise procedural results. The ability to implant the device without routine pre-dilatation is another possible advantage reducing associated risks and procedure times. The aim of this study is to report procedural and 30-day outcomes following TAVI in a consecutive patient group presenting with severe symptomatic aortic stenosis with the Lotus valve system without routine pre-dilatation...

OBJECTIVES: To assess the feasibility of axillary transcatheter aortic valve implantation (TAVI) using the Lotus valve. BACKGROUND: TAVI is used to treat patients with severe aortic stenosis, with transfemoral (TF) access being the safest and most widely used route. In patients unsuitable for this, there are reports that the axillary artery may be safest alternative access route. The Lotus device is a fully retrievable 2nd generation transcatheter heart valve which is licensed for femoral and transaortic access...

BACKGROUND: Second generation transcatheter aortic valve implantation (TAVI) devices have been designed to reduce the rate of paravalvular leak (PVL) and other complications. An important technological advancement has been the ability to fully reposition devices to facilitate optimal implantation depth and position to reduce the likelihood of PVL. OBJECTIVES: To compare procedural and 30-day outcomes according to the Valve Academic Research Consortium (VARC)-2 criteria following TAVI with the fully repositionable and retrievable Lotus and DFM devices...

BACKGROUND: Permanent pacemaker implantation (PPMI) after transcatheter aortic valve implantation is of high clinical relevance, but PPMI rates differ widely between valve types. Although the Lotus valve can be repositioned, reported rates for PPMI are high. The predictors of PPMI after Lotus valve implantation have not been defined yet. METHODS: We analyzed the impact of preexisting conduction disturbances, depth of implantation, oversizing, and amount of calcification on PPMI in 216 patients with severe symptomatic aortic stenosis underdoing Lotus valve implantation...

BACKGROUND: The fully retrievable and repositionable Lotus Valve System uses a unique mechanical expansion mechanism. Balloon aortic valvuloplasty (BAV) is recommended before valve deployment. There are no studies focusing on feasibility and efficacy of Lotus Valve implantation without previous BAV. METHODS AND RESULTS: Thirty consecutive patients (63.3% female; mean age, 80±6.2years) underwent transcatheter aortic valve replacement (TAVR) with the Lotus Valve without preparatory BAV...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is the method of choice for patients with severe aortic valve stenosis, who are ineligible or at high risk for surgery. Though TAVR leads to a significant reduction in mortality, a notable amount of patients are re-hospitalized early after TAVR. Parameters or biomarkers predicting outcome are therefore needed to identify patients who benefit most. Specific monocyte subsets have been associated with cardiovascular diseases and were shown to possess prognostic value...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is an established treatment option for patients with severe aortic stenosis and high surgical risk. Currently, various prosthesis types are available. Atrioventricular block (AVB) requiring pacemaker (PM) implantation is a typical complication after TAVI. This study investigated the recovery of AV node conduction and mid-term outcome of patients with or without PM implantation after TAVI according to prosthesis type. METHODS: From July 2008 to May 2015, 856 transcatheter heart valves were implanted at our center (age: 80...

OBJECTIVES: The aims of this study were to determine plasma elevations of biomarkers of myocardial injury associated with transfemoral (TF) transcatheter aortic valve replacement (TAVR) and to evaluate their prognostic value. BACKGROUND: Increases in biomarkers of myocardial injury are a common finding after TAVR, but their clinical significance is unclear. METHODS: In 756 consecutive TF TAVR patients, cardiac high-sensitivity troponin I (hsTnI) and creatine kinase MB (CK-MB) levels were measured at pre-defined time points to assess the occurrence of myocardial injury (defined as 15 times the upper reference limit for hsTnI [≥1...

OBJECTIVE: The aim of this study was to conduct a weighted meta-analysis to determine the rates of acute (≤30days) major outcomes after (TAVR) with second-generation devices. METHODS: A comprehensive search of multiple electronic databases from January 2011 to May 2017 was conducted using predefined criteria. New-generation TAVR devices were defined as any device which received CE mark approval or is still under evaluation for CE marking after CoreValve and SAPIEN XT prostheses...

Absence or minimization of PVL after TAVR and its potential association with higher rates of PPM placement has been the Achilles' heel of TAVR procedures. Pre-existing RBBB and depth of implantation are independent predictors of PPM need after Lotus valve implantation. Optimization of device design, increased operator experience, and focus on accurate device placement seem to result in decreased need for PPM after Lotus valve implantation.

OBJECTIVE: To report a first case series of the Lotus valve (Boston Scientific) for the treatment of surgical aortic bioprosthesis failure. BACKGROUND: Valve-in-valve (VIV) transcatheter aortic valve implantation (TAVI) is an established management option for surgical aortic bioprosthesis failure. Although TAVI has proven efficacious, complications relating to suboptimal valve implantation have been reported in approximately 5% of patients. The Lotus valve is fully repositionable and retrievable, and therefore enables complete assessment of valve function prior to definitive deployment...

New generation devices for transcatheter aortic valve replacement have been optimized to improve clinical outcome. We compared procedural, in-hospital, 30 days and 12 months outcome of the new generation repositionable Boston Lotus Valve and the balloon-expandable Edwards Sapien 3 valve with the last generation self-expandable Medtronic CoreValve and the balloon-expandable Edwards Sapien XT. Between 2010 and 2015 consecutive patients treated with the Medtronic CoreValve (N = 100), Edwards Sapien XT (N = 100), Edwards Sapien S3 (N = 100) and Boston Lotus device (N = 100) were enrolled...

OBJECTIVES: The authors report the incidence of pacemaker implantation up to hospital discharge and the factors influencing pacing rate following implantation of the LOTUS bioprosthesis (Boston Scientific, Natick, Massachusetts) in the United Kingdom. BACKGROUND: Transcatheter aortic valve replacement (TAVR) is associated with a significant need for permanent pacemaker implantation. Pacing rates vary according to the device used. The REPRISE II (Repositionable Percutaneous Replacement of Stenotic Aortic Valve Through Implantation of Lotus Valve System) trial reported a pacing rate of 29% at 30 days after implantation of the LOTUS device...
