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...

AIMS: The Valve Academic Research Consortium (VARC) endpoint definitions were established to standardise the reporting of clinical outcomes following transcatheter aortic valve implantation (TAVI). It remains unclear, however, to what extent and in which manner these definitions are applied. Therefore, we sought to investigate the utilisation and adherence to VARC guidelines since their introduction in 2011 across peerreviewed TAVI-related publications. METHODS AND RESULTS: We performed a systematic literature review to identify TAVI-related manuscripts published between February 2011 and February 2014...

AIMS: Our aim was to identify current discrepancies among European countries, and provide a basis for a general agreement on decision making specifically related to TAVI procedures. The European Association of Percutaneous
Coronary Interventions (EAPCI) therefore assessed the current status of transcatheter valve therapy (TAVI) in Europe through a web-based survey. METHODS AND RESULTS: Three hundred and one European centres responded to the survey (61.4% of the invited centres)...

In the United States, new surgical heart valves can be approved on the basis of objective performance criteria (OPC). In contrast, the US Food and Drug Administration traditionally requires stricter criteria for transcatheter heart valve (THV) approval, including randomized, clinical trials. Recent US Food and Drug Administration approval of new-generation THVs based on single-arm studies has generated interest in alternative study approaches for THV device approval. This review evaluates whether THV device approval could follow a pathway analogous to that of surgical heart valves by incorporating OPC and provides several considerations and recommendations...

OBJECTIVES: The purpose of this study was to assess the feasibility and safety of transcarotid transcatheter aortic valve replacement (TAVR). BACKGROUND: Many candidates for TAVR have challenging vascular anatomy that precludes transfemoral access. Transcarotid arterial access may be an option for such patients. METHODS: The French Transcarotid TAVR Registry is a voluntary database that prospectively collected patient demographics, procedural characteristics, and clinical outcomes among patients undergoing transcarotid TAVR...

OBJECTIVES: The aims of this study were to determine D-shaped mitral annulus (MA) dimensions in control subjects without significant cardiac disease and in patients with moderate to severe mitral regurgitation (MR) being considered for transcatheter mitral therapy and to determine predictors of annular size, using cardiac computed tomography. BACKGROUND: The recently introduced D-shaped method of MA segmentation represents a biomechanically appropriate approach for annular sizing prior to transcatheter mitral valve implantation...

BACKGROUND: Psoas muscle area (PMA) is a novel measure of frailty that can be efficiently measured from computed tomography images to help predict risk in older adults referred for transcatheter aortic valve replacement (TAVR). The objective of this study was to determine if PMA would be incrementally predictive of mortality and morbidity after TAVR. METHODS: The pre-TAVR computed tomography scans of 208 consecutive patients at 2 hospitals in Montreal and Munich were analyzed to measure the cross-sectional area of the left and right psoas muscles on a single axial slice at the level of L4...
