Importance: Transcatheter aortic valve replacement (TAVR) was approved by the US Food and Drug Administration for severe aortic stenosis in patients who cannot undergo surgery and for patients at high operative risk. Use of TAVR for off-label indications has not been previously reported. Objective: To evaluate patterns and adverse outcomes of off-label use of TAVR in US clinical practice. Design, Setting and Participants: Patients receiving commercially funded TAVR in the United States are included in the Transcatheter Valve Therapy Registry...

We here report the case of a stenosis of the CoreValve(®) system due to reduced mobility of prosthesis cusps for which a surgical replacement of the aortic valve was proposed. The exact mechanism leading to this impaired mobility of the leaflets is yet to be determined. We also underline the fact a transcatheter aortic valve implantation (TAVI) device can be replaced by a surgical replacement without excessive operative risks despite the patient being initially considered as high-risk.

Aims: The ADVANCE study was designed to evaluate the safety and effectiveness of transcatheter aortic valve implantation (TAVI) with a self-expanding bioprosthesis in real-world patients with symptomatic, severe aortic stenosis at high surgical risk for valve replacement. Methods and results: Study participants were enrolled from 44 experienced centres in 12 countries. Patient eligibility, treatment approach, and choice of anaesthesia were determined by the local Heart Team...

Aortic root replacement is indicated for aortic root aneurysm, small aortic root, and most root abscesses. This report describes the placement of a radiopaque marker during aortic root replacement using a Freestyle porcine bioprosthesis. This marker is a useful landmark during fluoroscopy for transcatheter valve-in-valve aortic valve replacement in the event of bioprosthesis degeneration.

Tetralogy of Fallot with absent pulmonary valve syndrome (TOF/APV) is a rare congenital malformation. Although pulmonary artery (PA) anomalies have been observed in TOF, its association with disconnected PA is extremely rare. We report successful stenting of the disconnected left PA in a 3-year-old boy with TOF/APV followed by surgical reimplantation. The significance of this transcatheter intervention for guidance during surgery and the importance of visualizing a ductal stump on angiography as an indicator of disconnected PA are discussed...

Transcatheter pulmonary valve implantation is established as a valuable option to reconstruct failing right ventricular outflow tract function. Percutaneous tricuspid valve-in-valve or valve-in-ring reconstruction is even applied with increasing acceptance. A 46-year-old woman with a diagnosis of carcinoid-dependent right heart failure underwent surgical bioprosthetic tricuspid and pulmonary valve replacement. Almost 1 year later, she presented again with markedly dilatated and reduced right heart function caused by degeneration of both biologic valves...

We present a case of transcatheter valve-in-valve replacement performed because of structural valve deterioration of a subcoronary implanted stentless aortic bioprosthesis. A 23-mm self-expandable transcatheter heart valve (THV) with supraannular seating was chosen. The procedure was performed with the patient under conscious sedation. After anchoring and partial valve deployment, the patient experienced an acute onset of angina. The angiogram showed left main coronary artery obstruction. Prompt resheathing and retrieval of the THV was performed, and the procedure was aborted...

We report a case of delayed treatment of a partial aortic valve leaflet avulsion during transcatheter aortic valve replacement (TAVR) and its successful management by a percutaneous snare retrieval technique. Post-TAVR transesophogeal echocardiography showed an avulsed native valve leaflet. We deferred retrieval of the mass with anticoagulant agents. One month later, a 30-mm EN-Snare was used to snare the mass. This case report demonstrates that the management of an avulsed aortic valve leaflet can be safely deferred with the use of an anticoagulant agent...

MitraClip is an approved therapy for mitral regurgitation (MR); however, health care resource utilization pre- and post-MitraClip remains understudied. METHODS: Patients with functional and degenerative MR at high surgical risk in the EVEREST II High-Risk Registry and REALISM Continued-Access Study were linked to Medicare data. Pre- and post-MitraClip all-cause death, stroke, myocardial infarction, heart failure (HF), and bleeding hospitalizations were identified. Inpatient costs, adjusted to 2010 US dollars, were calculated, and event rate ratios and cost ratios were estimated with multivariable modeling...

BACKGROUND: Safety and effectiveness of transcatheter aortic valve replacement (TAVR) in low-risk patients with symptomatic severe aortic stenosis have not yet been established. HYPOTHESIS: Transcatheter aortic valve replacement is feasible in patients with symptomatic severe aortic stenosis and low risk for surgical aortic valve replacement. DESIGN: The LRT study is the first US Food and Drug Administration-approved Investigational Device Exemption prospective multicenter feasibility trial of TAVR in low-risk patients...

The current delivery size of transcatheter aortic valves, limited by the thickness of their pericardial leaflets, correlates with a high prevalence of major vascular complications. Polyurethane valves can be developed to a fraction of the thickness of pericardial valves through the addition of carbon nanotubes to reinforce their leaflets. This study investigates the suitability of a novel carbon nanotube reinforced leaflet to reduce the delivery profile of transcatheter aortic valves. Carbon nanotube polyurethane composites were developed with thicknesses of 50 μm and their mechanical properties were determined in relation to various environmental effects...

BACKGROUND: the introduction of transcatheter aortic valve replacement (TAVR) expanded definitive therapy of aortic stenosis to many high-risk patients, but it has not been fully evaluated in the dialysis population. OBJECTIVES: We aimed to evaluate the current trend and in-hospital outcome of Surgical aortic valve replacement (SAVR) and TAVR in the dialysis population. METHODS: Severe aortic stenosis patients on maintenance dialysis who underwent SAVR or TAVR in the Nationwide Inpatient Sample database (NIS) from January 1, 2005, through December 31, 2014, were included in our comparative analysis...

AIMS: Self-expanding (SE) valves are characterized with long stent frame design and the radial force of the device exists both in the inflow and outflow level. Therefore, we hypothesized that device success of SE-valves may be influenced by ascending aortic dimensions (AAD). The aim of this study was to determine the influence of AAD on acute device success rates following SE transcatheter aortic valve replacement (TAVR). METHODS & RESULTS: In 4 centers in the United States and Asia, 214 consecutive patients underwent SE-TAVR...

INTRODUCTION: For a long time, a bicuspid valve has been considered a contraindication to transcatheter aortic valve implantation (TAVI) due to worse procedural results. Currently available technologies are changing the scenario, with initial experiences reporting much better results with second-generation devices. AREAS COVERED: This review will analyze the risk and potential pitfalls of TAVI on bicuspid valves and will try ascertain how the use of a new-generation fully repositionable device, the Lotus Valve System (LVS), could improve procedural and clinical results in bicuspid anatomies...

BACKGROUND: The Medtronic Evolut R (EVR) is a novel transcatheter heart valve designed to allow precise implantation at the intended position and to minimize prosthesis dysfunction as well as procedural complications. Our aim was to compare short-term functional and clinical outcomes of the new EVR with the established Medtronic CoreValve (CV) system. METHODS AND RESULTS: Of 151 patients undergoing transfemoral transcatheter aortic valve implantation with a self-expanding valve at our institution between January 2013 and January 2016, 86 were treated with EVR and 65 with CV...
