INTRODUCTION AND OBJECTIVES: TAVR is thought to change the volumes, characteristics, and outcomes of patients with aortic stenosis undergoing SAVR. We sought to investigate the impact of increasing transcatheter aortic valve replacement (TAVR) volumes on surgical aortic valve replacement (SAVR) volumes and to assess the evolution in baseline demographics and its impact on 30-day clinical outcomes across TAVR and SAVR patients. METHODS: From June 2007 through September 2015, 3543 consecutive patients with severe aortic stenosis who underwent TAVR (n=1407) or SAVR (n=2136) in a single center were subcategorized into nine cohorts defined by procedure year...

AIMS: The European Association of Percutaneous Coronary Interventions (EAPCI) assessed the current status of transcatheter valve therapy in Europe through a web-based survey. Our aim here was to report the results of that survey regarding trends in percutaneous mitral valve repair (PMVR) therapy. METHODS AND RESULTS: Among 301 European centres participating in the overall EAPCI survey, 246 (81.7%) responded to the PMVR section questions. A total of 176 (71.5%) have been undertaking a PMVR programme...

BACKGROUND: Although transcatheter aortic-valve replacement (TAVR) is an accepted alternative to surgery in patients with severe aortic stenosis who are at high surgical risk, less is known about comparative outcomes among patients with aortic stenosis who are at intermediate surgical risk. METHODS: We evaluated the clinical outcomes in intermediate-risk patients with severe, symptomatic aortic stenosis in a randomized trial comparing TAVR (performed with the use of a self-expanding prosthesis) with surgical aortic-valve replacement...

BACKGROUND: The surgical correction of functional mitral regurgitation (MR) remains challenging and controversial. The study aim was to systematically review the outcomes of surgical mitral valve repair (MVRpr) and mitral valve replacement (MVR) in patients with significant functional MR and left ventricular (LV) dysfunction. METHODS: A meta-analysis was performed of published data acquired from patients with moderate to severe functional MR and LV ejection fraction (LVEF) <40% who underwent surgical MVRpr or MVR...

Paravalvular leakage (PVL) occurs in 6%-15% of cases after surgical heart valve replacement. A percutaneous approach is increasingly used to close PVLs as an alternative to repeat surgery. Computed tomography (CT) can be used for simulation of fluoroscopic cardiac anatomy. This technique allows preprocedural definition of optimal C-arm angulations and PVL localization in reference to fluoroscopic views. It is very helpful for guidewire crossing of the PVL and positioning of the closure device. We report a case with the first use of dedicated software for fluoroscopic simulation (FluoroCT) in transcatheter mitral PVL closure...

Best practices for transcatheter aortic valve implantation with CoreValve include patient screening and valve size selection using multislice computed tomography, adherence to manufacturer recommendations for oversizing, control of implant depth to 6 mm or less, and management of conduction disturbances according to international guidelines. The ADVANCE II study implemented these strategies and demonstrated their relation to clinical outcomes. From October 2011 to April 2013, 200 patients with severe aortic stenosis were enrolled, and 194 were implanted...

Interventional cardiologists have traditionally relied upon fluoro-scopic imaging for percutaneous coronary interventions. Transcatheter structural heart interventions, however, require additional imaging modalities such as echocardiography and multislice computed tomography (MSCT) for pre-, intra- and post-procedural assistance. MSCT has emerged as the critical imaging modality for patient and device selection prior to transcatheter structural heart interventions. MSCT is unique as it provides a complete 3-dimensional (3D) dataset of the heart and vasculature that is amenable to multiplanar reconstruction for 2-dimensional (2D) or volume-rendered interpretations...

Individualised, patient-centred care is a central tenet of modern medicine. The variety of transcatheter heart valves currently available affords the opportunity to select the most appropriate device for each individual patient. Prosthesis selection should be based on operator experience and pre-procedural multimodal three-dimensional imaging. Herein, we outline a number of clinical scenarios where specific transcatheter heart valve technologies have the potential to optimise clinical outcome.

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)...

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...

OBJECTIVES: This study sought to evaluate the outcomes of the early experience of transcatheter mitral valve replacement (TMVR) with balloon-expandable valves in patients with severe mitral annular calcification (MAC) and reports the first large series from a multicenter global registry. BACKGROUND: The risk of surgical mitral valve replacement in patients with severe MAC is high. There are isolated reports of successful TMVR with balloon-expandable valves in this patient population...
