BACKGROUND: to determine reliability and reproducibility of measurements of aortic annulus in 3D models printed from cardiovascular computed tomography (CCT) images. METHODS: Retrospective study on the records of 20 patients who underwent aortic valve replacement (AVR) with pre-surgery annulus assessment by CCT and intra-operative sizing by Hegar dilators (IOS). 3D models were fabricated by fused deposition modelling of thermoplastic polyurethane filaments. For each patient, two 3D models were independently segmented, modelled and printed by two blinded "manufacturers": a radiologist and a radiology technician...

BACKGROUND: The clinical robustness of contrast-videodensitometric (VD) assessment of aortic regurgitation (AR) after transcatheter aortic valve implantation (TAVI) has been demonstrated. Correct acquisition of aortic root angiography for VD assessment, however, is hampered by the opacified descending aorta and by individual anatomic peculiarities. The aim of this study was to use preprocedural multi-slice computed tomography (MSCT) to optimize the angiographic projection in order to improve the feasibility of VD assessment...

Being physically active or, in a broader sense, simply moving more throughout each day is one of the most important components of an individual's health plan. In conjunction with regular exercise training, taking more steps in a day and sitting less are also important components of one's movement portfolio. Given this priority, health care professionals must develop enhanced skills for prescribing and guiding individualized movement programs for all their patients. An important component of a health care professional's ability to prescribe movement as medicine is competency in assessing an individual's risk for untoward events if physical exertion was increased...

Multislice computed tomography (MSCT) has emerged as the mainstay in patients planned for transcatheter aortic valve implantation (TAVI). Incidental findings (IF) in MSCT are common. However, the exact incidence, clinical relevance and further consequences of IF are unclear and it is controversial whether IF adversely affect patients' outcome. We analyzed MSCT data of 1050 patients screened for TAVI between January 2011 and December 2014. Median follow-up of patients was 20 months. In total, 3194 IF were identified, which were classified into clinically non-relevant IF (2872, 90%) and clinically relevant IF (322, 10%)...

The Centers for Medicare and Medicaid Services National Coverage Determination requires centers performing transcatheter aortic valve implantation (TAVI) to report clinical outcomes up to 1 year. Many sites encounter challenges in obtaining complete 1-year follow-up. We report our process to address this challenge. A multidisciplinary process involving clinical personnel, data and quality managers, and research coordinators was initiated to collect TAVI data at baseline, 30 days, and 1 year. This process included (1) planned clinical follow-up of all patients at 30 days and 1 year; (2) query of health-care system-wide integrated data warehouse (IDW) to ascertain last date of clinical contact within the system for all patients; (3) online obituary search, cross-referencing for unique patient identifiers to determine if mortality occurred in remaining unknown patients; and (4) phone calls to remaining unknown patients or patients' families...

Pre-procedural planning is the key element of transcatheter aortic valve implantation (TAVI). Multislice computed tomography of the chest, abdomen and pelvis with the ability to perform a 3-dimensional reconstruction has become the cornerstone of pre-procedural planning. We would like to encourage TAVI operators (interventional cardiologist and surgeons) to get involved in imaging. All TAVI operators should know how to assess the annulus, the annular root, and the iliofemoral access. We strongly believe that this will improve outcomes of this evolving procedure...

REVIEW
Vinayak Bapat
Transcatheter aortic valve implantation (TAVI) has emerged as a viable treatment modality for patients with severe aortic valve stenosis and multiple co-morbidities. More recent indications include the use of transcatheter heart valves (THV) to treat degenerated bioprosthetic surgical heart valves (SHV), which are failing due to stenosis or regurgitation. Valve-in-valve (VIV) procedures in the aortic position have been performed with a variety of THV devices, although the balloon-expandable SAPIEN valve platform (Edwards Lifesciences Ltd, Irvine, CA, USA) and self-expandable CoreValve platform (Medtronic Inc...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is a well-established treatment for patients with severe aortic valve stenosis. This procedure requires pre-operative planning by assessment of aortic dimensions on CT Angiography (CTA). It is well-known that the aortic root dimensions vary over the heart cycle. However, sizing is commonly performed at either mid-systole or end-diastole only, which has resulted in an inadequate understanding of its full dynamic behavior. STUDY GOAL: We studied the variation in annulus measurements during the cardiac cycle and determined if this variation is dependent on the amount of calcification at the annulus...

BACKGROUND: We investigated the application and feasibility of a novel software tool designed for the visualization of the aortic root during transcatheter aortic valve implantation (TAVI). The final positioning of the device prior deployment remains the most critical phase during TAVI. METHODS: Philips "Vascular Outlining" prototype application was used during balloon expandable Edwards Lifesciences SapienXT valve deployment. It processes any angiographic sequences, extracting the static outline of vessels and projecting the two- dimensional vessel margins as a roadmap on live fluoroscopy...

Transcatheter aortic valve implantation (TAVI) has proven to be the standard of care for patients with prohibitive and high operative risk; today, it is considered a reasonable alternative to surgical aortic valve replacement in intermediate-risk patients. As indications for TAVI move toward patients at lower risk, safety aspects are becoming even more important. Furthermore, adequate patient selection is key for predictable procedural success with minimal complications, translating into an optimal clinical outcome...

Aims: Treatment of tricuspid regurgitation (TR) is common after surgery for mitral and/or aortic valves. The prognostic role of moderate to severe TR in patients undergoing mitraclip or transcatheter aortic valve implantation (TAVI) is not well-defined. Thus, the aim of this article is to perform a systematic review and meta-analysis of articles valuing the prognostic role of TR for patients undergoing mitraclip and TAVI. Methods and results: Articles were searched in Pubmed, Cochrane Library, Google Scholar and Biomed Central in September 2016...

BACKGROUND: While short-term outcomes for patients undergoing transcatheter aortic valve implantation (TAVI) have long been studied, there is very little data on their predictors. We aimed to identify the predictors of outcomes, such as intensive care unit (ICU) and in-hospital length of stay (LOS), duration of postoperative intubation and in-hospital mortality, after TAVI procedures. METHODS: We conducted a retrospective cohort study of 162 consecutive patients with aortic valve disease, who were admitted to a tertiary hospital of Liverpool for TAVI, during a five-year period...

BACKGROUND: Despite the health benefits of increasing physical activity in the secondary prevention of acute coronary syndrome (ACS), up to 60% of ACS patients are insufficiently active. Evidence supporting the effect of Web-based interventions on increasing physical activity outcomes in ACS patients is growing. However, randomized controlled trials (RCTs) using Web-based technologies that measured objective physical activity outcomes are sparse. OBJECTIVE: Our aim is to evaluate in insufficiently active ACS patients, the effect of a fully automated, Web-based tailored nursing intervention (TAVIE en m@rche) on increasing steps per day...
