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: A comparison was made between the accuracy of and time saved by using novel automated software for pre-procedural computed tomography (CT) planning before transcatheter aortic valve implantation (TAVI) and manual methods. Preprocedural CT to assess aortic annulus dimensions and predict the optimal C-arm implant angle before TAVI can reduce complications related to incorrect prosthesis sizing and positioning. METHODS: A total of 61 consecutive patients underwent TAVI using either the SAPIEN XT or CoreValve prosthesis...

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...

Transcatheter aortic valve implantation (TAVI) has emerged as an alternative technique to treating aortic stenosis in patients with high surgical risk. We present a case of a successful transfemoral TAVI in a high-risk patient with an extremely tortuous iliofemoral system and a significant S-type bend in the descending aorta. With careful preprocedure planning and using all the techniques available, TAVI can be performed in the most challenging patients.

Coronary artery disease (CAD) is often present in patients with severe aortic valve stenosis candidates to transcatheter aortic valve implantation (TAVI). Mild CAD may also worsen and need treatment years after TAVI. The implantation of a transcatheter valve may interfere with the capability of reengaging the coronary arteries. We prospectively assessed the feasibility of performing coronary angiography (CA), fractional flow reserve, and, where indicated, percutaneous coronary intervention after valve implantation in a consecutive series of patients with CAD undergoing TAVI...

This report describes an elderly severe aortic stenosis (AS) patient, who had a history of coronary artery bypass grafting and endovascular repair for an abdominal aortic aneurysm (AAA). Type II endoleak with enlargement of AAA was diagnosed and ligation of inferior mesenteric artery (IMA) was recommended. Because aortic valve replacement (AVR) was high risk, we planned transcatheter aortic valve implantation (TAVI). Considering risks of IMA ligation under dual antiplatelet therapy, increased blood pressure after TAVI, and general anesthesia, we performed combined TAVI and IMA ligation...

An 82-year-old woman with severe aortic stenosis was referred. She had previously undergone mitral valve replacement. We planned transcatheter aortic valve implantation (TAVI) with transfemoral approach. We planned to use the Safari-dedicated TAVI guidewire. No studies have reported clinical application of the dedicated TAVI guidewire in a patient with the previous mitral valve replacement. Thus, we conducted a simulation using a three-dimensional heart model to confirm the safety of the procedure. The procedure was successful without any complications...
