BACKGROUND: The Medtronic Evolut R (EVR) is a novel transcatheter heart valve designed to allow precise implantation at the intended position and to minimize prosthesis dysfunction as well as procedural complications. Our aim was to compare short-term functional and clinical outcomes of the new EVR with the established Medtronic CoreValve (CV) system. METHODS AND RESULTS: Of 151 patients undergoing transfemoral transcatheter aortic valve implantation with a self-expanding valve at our institution between January 2013 and January 2016, 86 were treated with EVR and 65 with CV...

Transcatheter aortic valve implantation (TAVI) is a rapidly evolving therapeutic modality currently available for patients with severe aortic stenosis (AS) that are unsuitable for surgery because of technical/anatomical issues or high-estimated surgical risk. Transfemoral approach is the preferred TAVI delivery route when possible. Alternative non-transfemoral access options include transaortic, trans-subclavian and transapical access. Other approaches are also feasible (transcarotid, transcaval, and antegrade aortic) but are restricted to operators and hospitals with experience...

The aim of this review is to highlight the technical details and the scientific data on percutaneous coronary interventions (PCIs) in chronic total occlusion (CTO) performed by transradial approach (TRA). Transfemoral approach (TFA) is commonly regarded as the standard for CTO PCI, but there are a growing number of CTO recanalization procedures performed by TRA. We discuss the relevant technical details to approach a CTO by transradial access, especially the compatibility of various CTO recanalization techniques with specific guiding catheter sizes...

Restoring locomotion functionality of transfemoral amputees is essential for early rehabilitation treatment and for preserving mobility and independence in daily life. Research in wearable robotics fostered the development of innovative active mechatronic lower-limb prostheses designed with the goal to reduce the cognitive and physical effort of lower-limb amputees in rehabilitation and daily life activities. To ensure benefits to the users, active mechatronic prostheses are expected to be aware of the user intention and properly interact in a closed human-in-the-loop paradigm...

Understanding the characteristics of ground reaction forces (GRFs) on both limbs during sprinting in unilateral amputees wearing running-specific prostheses would provide important information that could be utilized in the evaluation of athletic performance and development of training methods in this population. The purpose of this study was to compare GRFs between intact and prosthetic limbs during sprinting in unilateral transfemoral amputees wearing running-specific prostheses. Nine sprinters with unilateral transfemoral amputation wearing the same type of prosthesis performed maximal sprinting on a 40 m of runway...

We compared the efficacy and safety of the transradial approach percutaneous coronary intervention (TRA-PCI) and transfemoral approach percutaneous coronary intervention (TFA-PCI) for bypass grafts lesions. Patients (n = 184) were retrospectively enrolled. Less contrast was used during the procedure in the TRA group than in the TFA group, 201.5 (45.5) mL versus 221.5 (49.1) mL, P = .004, although fluoroscopy time was longer in the TRA group, 22.5 (6.3) minutes versus 20.3 (6.1) minutes; P = .017. The incidence of net adverse clinical events (NACEs) was lower in the TRA group than in the TFA group (3...

Delivery of stent grafts during thoracic endovascular aortic replacement can be challenging, especially in aortic arches with severe angulation. Several techniques have been recommended to achieve this. We introduce a simple technical method, transfemoral snare-assisted device advance, which was successful in a 72-year-old woman with an aneurysm in a severely angulated aortic arch and review various technical tips.

Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an endovascular technique that allows for temporary occlusion of the aorta in patients with severe, life-threatening, trauma-induced noncompressible hemorrhage arising below the diaphragm. REBOA utilizes a transfemoral balloon catheter inserted in a retrograde fashion into the aorta to provide inflow control and support blood pressure until definitive hemostasis can be achieved. Initial retrospective and registry clinical data in the trauma surgical literature demonstrate improvement in systolic blood pressure with balloon inflation and improved survival compared to open aortic cross-clamping via resuscitative thoracotomy...

AIMS: Previous studies showed lower rates of in-hospital complications and mortality for patients undergoing surgical aortic valve replacement (sAVR) in high-volume compared with lower-volume hospitals. Smaller studies have suggested similar inverse relationship for transcatheter aortic valve implantation (TAVI). METHODS AND RESULTS: We analyzed all patients with non-emergent transfemoral (TF) TAVI procedures performed in 2014 in 87 German hospitals. We used the German Aortic Valve Score 2...

Pacemaker lead extractors must become familiar with transfemoral approaches for lead extraction as a bail-out procedure for a failed superior approach. We presented a "tetra-axial" system for transfemoral lead extraction. This system would be more widely applicable in cases with difficulties in extraction, resulting in more procedural success.

The transradial approach (TRA) has become an attractive alternative to the transfemoral approach (TFA) in percutaneous coronary intervention. To date, however, these two approaches have not been systematically compared in various percutaneous peripheral artery interventions (PPAIs). In the present study 258 patients with peripheral artery disease that underwent PPAI via the TRA (n=75) or the TFA (n=183) were analyzed. Clinical factors and outcomes in these two groups were compared. The puncture time was significantly longer (P<0...

Vascular complications are common after transcatheter aortic valve replacement (TAVR) and are associated with increased morbidity and mortality. Stent graft implantation enables percutaneous treatment of access site bleeding; however, the efficacy and durability and of this approach are unknown. We studied the immediate outcome of stent graft implantation for control of access site bleeding and the need for repeat vascular interventions after stenting, in a cohort of consecutive patients with severe symptomatic aortic stenosis who underwent transfemoral TAVR...

OBJECTIVES: Transaortic (TAo) access for transcatheter aortic valve implantation (TAVI) is an alternative to the conventional transfemoral or transapical routes. Data comparing the characteristics and outcomes of TAo-TAVI using the SAPIEN XT and SAPIEN 3 heart valves are scarce. The objective of the current analysis was to provide such information. METHODS: ROUTE is an international, prospective, observational registry. Patients with severe calcific aortic stenosis scheduled for TAo-TAVI with an Edwards SAPIEN XT or a SAPIEN 3 heart valve were consecutively enrolled at 22 centres across Europe between February 2013 and February 2015...

Intravascular ultrasonography (IVUS) is a highly effective method of diagnosis of post-thrombotic obstructions. Its possibilities by determining the degree and extension of obstructions of deep veins are superior to those of not only non-invasive methods of examination (ultrasonography, CT and MRI) but of phlebography whose results until recently were considered fundamental in diagnosis of the disease concerned. Limited possibilities of phlebography often lead to diagnostic errors when determining the degree and extension of post-thrombotic obstructions...
