INTRODUCTION AND OBJECTIVES: Transcatheter aortic-valve implantation (TAVI) is an accepted treatment for patients with severe aortic stenosis and high surgical risk. However, there is lack in data about TAVI in low-risk patients that are already being treated with this therapy in some clinical contexts. METHODS: A retrospective analysis of patients treated with transfemoral TAVI using Edwards Sapien prosthesis in one center was performed, classifying the patients into three groups according to the surgical risk (high/intermediate/low risk for STS score>8/4-8/<4)...

Pulmonary valve replacement via surgical implantation of a bioprosthetic valve (BPV) is a well-established treatment for patients with dysfunctional RV outflow tracts. BPVs are prone to structural deterioration, and will eventually require replacement. Recently, percutaneous valve-in-valve (VIV) placement of transcatheter valves has established itself as a safe and effective alternative to surgical revision. Unfortunately, VIV therapy is inherently limited by the inner diameter of the BPV, which restricts the number of eligible patients...

BACKGROUND: The impact of coronary artery disease (CAD) on outcomes after transcatheter aortic valve replacement (TAVR) is understudied. Literature on the prognostic role of CAD in the survival of patients undergoing TAVR shows conflicting results. This meta-analysis aims to investigate how CAD impacts patient survival following TAVR. METHODS AND RESULTS: We completed a comprehensive literature search of Embase, MEDLINE, and the Cochrane Library, and included studies reporting outcome of TAVR based on CAD status of patients for the analysis...

BACKGROUND: Patients with congenital or acquired heart defects affecting the pulmonary valve and right ventricular outflow tract (RVOT) commonly require multiple surgical interventions, resulting in significant morbidity. A less invasive alternative is percutaneous pulmonary valve implantation (PPVI). Though studies have previously reported the safety and efficacy of the early generation transcatheter heart valves (THVs), data on more recent devices are severely lacking. METHODS AND RESULTS: We performed a multinational, multicentre, retrospective, observational registry analysis of patients who underwent PPVI using the Edwards SAPIEN XT THV...

BACKGROUND: There is an increasing trend towards shorter hospital stays after transcatheter aortic valve implantation (TAVI), in particular for patients undergoing the procedure via transfemoral (TF) access. Preliminary data suggest that there exists a population of patients that can be discharged safely very early after TF-TAVI. However, current evidence is limited to few retrospective studies, encompassing relatively small sample sizes. METHODS: The Feasibility And Safety of early discharge after Transfemoral TAVI (FAST-TAVI) registry is a prospective observational registry that will be conducted at 10 sites across Italy, the Netherlands and the UK...

The human FMO2 (flavin-containing monooxygenase 2) gene has been shown to be involved in innate immunity against microbial infections, including tuberculosis (TB), via the modulation of oxidative stress levels. It has also been found to possess a curious loss-of-function mutation (FMO2*1/FMO2*2) that demonstrates a distinctive differentiation in expression, function and ethno-geographic distribution. However, despite evidences of ethnic-specific genetic associations in the inflammatory profile of TB, no studies were done to investigate whether these patterns of variations correlate with evidences for the involvement of FMO2 in antimicrobial immune responses and ethnic differences in the distribution of FMO2 polymorphisms except for some pharmacogenetic data that suggest a potentially deleterious role for the functional variant (FMO2*1)...

OBJECTIVES: The most commonly used accesses for transcatheter aortic valve implantation (TAVI) are the transfemoral (TF-TAVI) and the transapical (TA-TAVI) ones. There are concerns about TA-TAVI use in patients with reduced left ventricular ejection fraction (LVEF). The aim of this retrospective multicentre study was to compare the outcomes of TA-TAVI and TF-TAVI in patients with poor LVEF. METHODS: Patients with LVEF ≤35% were included in the analysis. Data were obtained from the Italian Transcatheter Balloon-Expandable Registry (ITER), which enrolled patients undergoing TAVI with the Sapien bioprosthesis in 33 national centres...

BACKGROUND: Surgical aortic valve replacement in patients with small annular dimensions is challenging because they are at increased risk for prosthesis-patient mismatch and impaired outcomes. Transcatheter aortic valve replacement might be a good alternative; however, comparative data on different transcatheter heart valves are missing. METHODS AND RESULTS: This multicenter, propensity score-matched study compared hemodynamics and early clinical outcomes in 246 patients with an aortic annulus area <400 mm(2) undergoing transcatheter aortic valve replacement with either a self-expanding transcatheter heart valve (Symetis ACURATE neo, n=129) or a balloon-expandable transcatheter heart valve (Edwards SAPIEN 3, n=117)...

OBJECTIVES: Patients with symptomatic severe mitral annular calcification present a therapeutic challenge. Direct transatrial implantation of SAPIEN valve has emerged as an alternative to surgical mitral valve (MV) replacement for high-risk surgical candidates. METHODS: This series includes 6 consecutive patients with symptomatic severe mitral annular calcification deemed to be at high risk for standard surgery. All patients underwent direct transatrial implantation of balloon-expandable SAPIEN valve in the mitral position...

BACKGROUND: Despite a lack of clear evidence, current European guidelines recommend antiplatelet therapy after transcatheter aortic valve replacement (TAVR). Recent investigations suggest that bioprosthesis thrombosis after TAVR is not uncommon and may be prevented by anticoagulation, but not by antiplatelet therapy. AIMS: The study objective was to assess the impact of the antithrombotic regimen on post-TAVR early haemodynamics. METHODS: Patients eligible for TAVR with an Edwards SAPIEN 3 valve were included in this prospective observational study...

Left ventricular outflow tract (LVOT) calcium is known to be associated with adverse procedural outcomes after transcatheter aortic valve implantation (TAVI), yet its effect on midterm outcomes has not been previously investigated. The aim of this study was to determine the influence of LVOT calcium on 2-year mortality after TAVI. A total of 537 consecutive patients underwent TAVI and 2 groups were established, stratified based on the severity of the LVOT calcium. The primary outcome was 2-year overall survival rate...

A 59-year-old female with Tetralogy of Fallot had a previous complete repair with RVOT patch enlargement. She developed subsequent severe symptomatic (NYHA III) pulmonary regurgitation with severe RV dilatation. She had a concomitant interstitial lung disease secondary to hypersensitivity pneumonitis that precluded her from cardiac surgery. After preprocedural assessment using computed tomography, echocardiography and invasive angiography we decided to implant a 29 mm Edwards Sapien 3 valve without pre-stenting...

We describe the case of a 57-year-old man who had severe mitral valve stenosis and regurgitation without significant annular calcification. He was not a candidate for surgical valve replacement or repair because of his substantial comorbid conditions, overall frailty, and elevated surgical risk. He underwent successful transcatheter mitral valve replacement of his native mitral valve with compassionate, off-label use of an Edwards Sapien 3 valve. A search of the literature produced no other cases like ours, which represents a further evolution of the transcatheter valve implantation concept...

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...

The case is reported of a successful transcatheter implantation of an Edwards SAPIEN 3 valve (29 mm) into a failing tricuspid bioprosthesis (Sorin Pericarbon, 31 mm). The procedure was performed in a 69-year-old woman with post-rheumatic mitral and tricuspid valve disease. Multiple previous cardiac surgeries precluded the use of another surgical approach. A large, organized, two-piece thrombus in the enlarged right atrium was not considered an absolute contraindication to the procedure. The SAPIEN 3 valve was implanted under general anesthesia, via a femoral venous access, under three-dimensional transesophageal echocardiography guidance...

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...
