INTRODUCTION: It has been suggested that sudden cardiac death (SCD) contributes around 50% of cardiovascular and 27% of all-cause mortality in hemodialysis patients. The true burden of arrhythmias and arrhythmic deaths in this population, however, remains poorly characterised. Cardio Renal Arrhythmia Study in Hemodialysis (CRASH-ILR) is a prospective, implantable loop recorder single centre study of 30 established hemodialysis patients and one of the first to provide long-term ambulatory ECG monitoring...

The method of cyanoacrylate-mediated obliteration of subcutaneous veins is known to be an alternative to thermal endovascular obliteration and eliminates the need for tumescent anaesthesia. This technique is based on glue-induced damage to the venous intima, followed by immune response according to the delayed-type hypersensitivity principle. The authors report herein their first experience with using cyanoacrylate-mediated embolization in treatment of patients presenting with varicose veins. The operation was carried out using the VenaSeal closure system (Medtronic)...

 Deep brain stimulation (DBS) is a growing treatment option for movement and psychiatric disorders. As DBS technology moves toward directional leads with increased numbers of smaller electrode contacts, trial-and-error methods of manual DBS programming are becoming too time-consuming for clinical feasibility. We propose an algorithm to automate DBS programming in near real-time for a wide range of DBS lead designs. Approach: Magnetic resonance imaging and diffusion tensor imaging are used to build finite element models that include anisotropic conductivity...

The present report describes the management of massive proximal type 1 endoleak with an enlarged symptomatic aneurysmal sac. Urgent treatment was performed using in situ laser fenestration of an aortic proximal extension facing renovisceral ostia. Image fusion was obtained intraoperatively. For each target vessel (superior mesenteric and two renal arteries), an Aptus HeliFX steerable sheath (Medtronic) inserted through femoral access was curved to face the vessel's ostium marker. A laser catheter (Spectranetics) was used to traverse the stent-graft and insert a 0...

BACKGROUND: Subcutaneous ICDs provide an alternative to transvenous defibrillation but require higher shock outputs and offer no anti-tachycardia pacing. The SPACE study evaluated the feasibility of pacing from an extravascular substernal location. OBJECTIVE: The primary purpose of the SPACE study was to characterize pacing from the substernal space. Secondary objectives included evaluating extracardiac stimulation and recording electrograms. METHODS: The SPACE study prospectively evaluated the feasibility of pacing with a commercially available EP catheter (Medtronic Marinr®, 7 Fr) acutely implanted in the substernal space via minimally invasive subxiphoid access...

BACKGROUND: Nasal bone osteotomy subjectively judges the position for osteotomy by visual inspection and by manual feel using the fingertip. Therefore, the outcome depends on the surgeon's experience and mastery of the procedure is technically challenging. METHODS: The authors applied a navigation system for the intraoperative evaluation of the osteotomy line and reduction position in 5 patients with malunited nasal bone fracture. The authors performed the operation with a temporal bone post developed for otologic surgery using Stealth Station S7 System (Medtronic, Minneapolis, MN)...

BACKGROUND: In the operative treatment of osteoporotic vertebral body fractures, a dorsal stabilization in combination with a corpectomy of the fractured vertebral body might be necessary with respect to the fracture morphology, whereby the osteoporotic bone quality may possibly increase the risk of implant failure. In order to achieve better stability, it is recommended to use cement-augmented screws for dorsal instrumentation. Beside careful endplate preparation cement augmentation of the adjacent endplates has also been reported to lead to less reduction loss...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) using a self-expanding valve has been shown to be superior to an open operation in high-risk patients. Extensive iliofemoral peripheral vascular disease can prohibit femoral access. In these cases, direct aortic (DA) implantation may be a suitable option. METHODS: The current analysis compared outcomes in patients undergoing TAVR with the self-expanding CoreValve prosthesis (Medtronic, Minneapolis, MN) by direct aortic (DA) access vs iliofemoral (IF) access...

Ventricular-assist devices (VADs) have seen increased utilization in the pediatric population. Formerly, this therapeutic modality was limited to only the pulsatile VAD, EXCOR (Berlin Heart GmbH). However, the continuous flow VAD devices, HeartMate II (Abbott Inc.) and HeartWare (Medtronic Inc.), are now increasingly used in this population. Postoperatively, VAD patients are acutely anticoagulated using unfractionated heparin, often beginning 24 to 48 hours after VAD placement. Once the patient is stabilized and ready to transition to a lower acuity or outpatient setting, low-molecular-weight heparin or warfarin therapy may be instituted...

OBJECTIVE: Topical nasal anesthetic (TNA) is used when evaluating pharyngeal swallowing with high-resolution manometry (HRM). It is unclear if desensitizing the nasal mucosa improves procedure tolerability or affects pharyngeal pressure. This study evaluated the effects of TNA on comfort and pharyngeal pressure using HRM. METHODS: A double-blinded study was conducted with 20 healthy participants ( x¯ = 27 years). Participants performed five saliva and five 10-mL swallows during two exams with ManoScan HRM ESO catheter (Medtronic, Minneapolis, MN) randomized under placebo (nonanesthetic lubricant) and anesthetized (0...

Post-thyroidectomy neck hematoma represents a major concern for surgeons because it can result in severe and even life-threatening complications. In fact, postoperative hemorrhage may result in airway compression and respiratory distress, and therefore, effective hemostasis is an important goal in thyroid surgery. Postoperative hematoma occurs at a rate of approximately 0.1% to 1.1%. Almost all cases occur in the first 6 h after surgery and can be the result of several surgeon or patient factors. For many years the clamp-and-tie technique has been the most common way to divide the main vascular pedicles of the thyroid gland...
