Background. In the domain of health behavior change, the deployment and utilization of information and communications technologies as a way to deliver interventions appear to be promising. This article describes the development of a web-based tailored intervention, TAVIE en santé, to support people living with HIV in the adoption of healthy behaviors. Methods. This intervention was developed through an Intervention Mapping (IM) framework and is based on the theory of planned behavior. Results. Crucial steps of IM are the selection of key determinants of behavior and the selection of useful theory-based intervention methods to change the targeted determinants (active ingredients)...

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.

PURPOSE: The aim of this study was to report the safety of coronary rotational atherectomy (RA) in patients with severe aortic stenosis (AS). RA in the clinical setting seems challenging because coronary slow flow leads to hemodynamic instability. METHODS: Between October 2013 and May 2016, 1401 patients in the Optimized transCathEter vAlvular iNtervention (OCEAN) registry in Japan underwent transcatheter aortic valve implantation (TAVI). The primary study endpoint was procedural success, defined as residual stenosis <20% with final Thrombolysis in Myocardial Infarction flow 3...

AIMS: While TAVI is the treatment of choice in patients with aortic stenosis considered inoperable or at high risk, interventional replacement of the mitral valve is still in the preclinical or early clinical phase. Our aim was to report on the first transcatheter double valve replacement into native valves from a transapical access. METHODS AND RESULTS: A 67-year-old, highly symptomatic female patient considered inoperable due to severe calcification of the mitral annulus and comorbidities was scheduled for transcatheter double valve replacement by the local Heart Team...

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...

As more patients become eligible for transcatheter aortic valve implantation (TAVI), resource allocation and early discharge planning require careful consideration. TAVI centers must develop locally appropriate and systematic strategies to facilitate early discharge and seamless post-discharge care. While ongoing studies examine pacing requirements post-TAVI, trials comparing general anesthesia and monitored analgesia care are desired. Future technologies for co-registration of computed tomography with fluoroscopy may reduce the need for intra-operative transesophageal echo and general anesthesia...

BACKGROUND: Surgical aortic bioprosthetic valves deteriorate 10 to 20 years after operation. Valve-in-valve implantation with first generation transcatheter aortic valve implantation (TAVI) devices has shown to be feasible. We report a first case series with the new Edwards Sapien 3 valve for transfemoral aortic valve-in-valve implantation. METHODS AND RESULTS: Nine patients underwent valve-in-valve-TAVI with the Edward Sapien 3 valve. Seven patients presented with severe aortic stenosis and two patients with severe aortic insufficiency of surgical aortic bioprosthesis...

BACKGROUND: Many older patients with aortic stenosis are excluded from surgical intervention due to multiple comorbidities. For these patients, transcatheter aortic valve implantation (TAVI) is a viable treatment alternative. Cardiothoracic computed tomography (CT) provides detailed anatomic assessment of the aortic root structures for patient selection, preprocedural planning, and intraoperative decision-making; however, nonaortic incidental findings are frequently detected. The prevalence and clinical significance of these findings have not been well described...

An 80-year-old woman with severe aortic stenosis was planned to undergo transcatheter aortic valve implantation (TAVI) under general anesthesia. Due to severe stenosis of the femoral arteries, the left iliac artery was cut down and a 16 F Edwards SAPIEN Expandable Sheath (eSheath : Edwards Lifesciences, Irvine, CA) was inserted into the artery smoothly. After balloon aortic valvuloplasty (BAV), an artificial valve was tried to deploy but stuck in the middle of eSheath. Suddenly regional saturation of oxygen (rSO2) at the ipsilateral foot decreased steeply without other significant hemodynamic instabilities...

Aortic stenosis (AS) is the most common primary valve disorder in the elderly with an increasing prevalence; transcatheter aortic valve implantation (TAVI) has become an accepted alternative to surgical aortic valve replacement (AVR) in the high risk or inoperable patient. Appropriate selection of patients for TAVI is crucial and requires a multidisciplinary approach including cardiothoracic surgeons, interventional cardiologists, anaesthetists, imaging experts and specialist nurses. Multimodality imaging including echocardiography, CT and MRI plays a pivotal role in the selection and planning process; however, echocardiography remains the primary imaging modality used for patient selection, intra-procedural guidance, post-procedural assessment and long-term follow-up...

Transcatheter Aortic Valve Implantation (TAVI) is increasingly being used in patients with severe aortic stenosis who are not candidates for surgery. ECG-gated CT angiography (CTA) plays an important role in the preoperative planning for these devices. As the number of patients undergoing these procedures increases, a subset of patients is being recognized who have contraindications to iodinated contrast medium, either due to a prior severe allergic type reaction or poor renal function. Another subgroup of patients with low flow and low gradient aortic stenosis is being recognized that are usually assessed for severity of aortic stenosis by stress echocardiography...

Prosthesis positioning in transcatheter aortic valve implantation procedures represents a crucial aspect for procedure success as demonstrated by many recent studies on this topic. Possible complications, device performance, and, consequently, also long-term durability are highly affected by the adopted prosthesis placement strategy. In the present work, we develop a computational finite element model able to predict device-specific and patient-specific replacement procedure outcomes, which may help medical operators to plan and choose the optimal implantation strategy...
