BACKGROUND: As the number of transcatheter aortic valve implantation (TAVI) procedures is constantly increasing, it is important to consider common complications, such as pacemaker (PM) implantation, and their specific risk factors. AIMS: Echocardiographic, computed tomography and electrocardiographic data were analysed to determine the predicting factors, if any, associated with PM implantation. METHODS: This retrospective study included patients referred to Nancy University Hospital for a TAVI procedure from January 2013 to December 2015...

A panel of experts drawn from neurology, psychiatry, geropsychiatry, geriatrics, and pharmacy representatives of 3 health plans convened in New York City on July 30, 2016, with the objective of sharing opinions, ideas, and information regarding the optimal management of Parkinson's disease psychosis (PDP). Three key points emerged from the discussion: (1) Because of the nature of Parkinson's disease and PDP, finding appropriate treatment can prove challenging; (2) emerging therapies may present an opportunity for effective disease management; and (3) moving forward, provider and patient education regarding PDP and available treatment options is essential for well-managed symptoms and better quality of life...

BACKGROUND: The pipeline embolization device (PED; Medtronic, MN, USA) can sometimes herniate into the aneurysmal sac in an unexpected manner during or shortly after its deployment due to device foreshortening. In this report, we describe 2 endovascular techniques, which can be used to reposition a herniated PED construct into a more favorable alignment. SUMMARY: In a 67-year-old patient who had an intraprocedural herniation of a PED device into a giant cavernous aneurysm, a stent anchor technique was used to reverse the herniation, reorient the PED construct, and achieve successful flow diversion...

Successful treatment of hypothalamic hamartoma (HH) can result in the resolution of its sequelae including epilepsy and rage attacks. Risks and morbidity of open surgical management of this lesion have motivated the development of laser interstitial thermal therapy (LITT) as a less invasive treatment approach to the disease. Although overall morbidity and risk would appear to be lower, complications related to LITT therapy have been reported, and the longer-term follow-up that is now possible after initial experience helps address the question of whether LITT provides equivalent efficacy compared to other treatment options...

OBJECTIVE: Hostile proximal aortic neck (HN) challenges the suitability for standard endovascular aneurysm repair (EVAR) of patients at high risk for "open" repair. However, there has been little if any focus placed on the individual role of the "nonlength" HN features in EVAR outcomes. The aim of this study was to evaluate their individual and potentially predictive role in outcomes of EVAR under HN conditions. METHODS: Data of 156 consecutive EVAR patients with short (<15 mm) HN, treated with the Endurant device (Medtronic Cardiovascular, Santa Rosa, Calif) at three European academic vascular centers between 2007 and 2015, were collected and retrospectively analyzed...

PURPOSE: The second-generation cryoballoon (CB-A, Arctic Front Advance, Medtronic, Minneapolis, MN, USA) has proven to be highly effective in achieving freedom from atrial fibrillation; nonetheless, the ideal number and duration of freezing cycles is still a matter of debate. We investigated the acute success, procedural complications, and clinical outcome of a single freeze strategy using the CB-A in a large, retrospective, international multicenter study. METHODS: Between January 2013 and September 2015, 818 consecutive patients (58 ± 12 years, 68% males) with drug-resistant atrial fibrillation (AF) who underwent a CB-A using a single freeze strategy were taken into consideration for our analysis...

Since it was introduced 17 years ago, capsule endoscopy has become an important diagnostic tool for the small bowel. Three generations of the original small bowel capsule have been developed since (PillCam SB3, Medtronic, USA), and four competitors were introduced for the small bowel. A non-video patency capsule (Agile patency capsule, Medtronic, USA) was also developed, in order to confirm patency and thus avoid retention in the GI tract. Moreover, capsules viewing other organs of the body (esophagus, colon) as well as three different magnetic guided capsules that visualize the stomach as good as optical endoscopy (OE) have been developed...

We introduce assistive techniques for proximal anastomosis in off-pump minimally invasive coronary artery bypass grafting (MICS CABG) to overcome difficult access to the ascending aorta in MICS CABG. An 8-cm left thoracotomy is made in the fifth intercostal space. ThoraTrak retractor (Medtronic Inc, Minneapolis, MN USA) is used to open the thoracotomy and is pulled to the cephalad and rightward direction toward to the ascending aorta. The pericardium is opened from the ascending aorta to the left ventricular apex and to the inferior vena cava...

A 58-year-old woman received a dual chamber pacemaker (Medtronic) for sick sinus syndrome. Given intact AV conduction the Managed Ventricular Pacing mode algorithm (MVP) was programmed. The day after, she suffered from palpitations. Her ECG showed a possible loss of atrial capture accompanied by atrial undersensing. Telemetry-supported pacemaker control confirmed the loss of capture. Undersensing of atrial signal was functional, related to long atrial refractory period in MVP mode algorithm. Device algorithms could induce false suspicions...

With new surgical techniques, more and more complex congenital heart defects are treated requiring sometimes right ventricle to pulmonary artery conduit implantation. In order to extend RV to PA conduit lifespan, 15 years ago a valved stent was developed. The implantation technique was progressively standardized to decrease risks of procedural complications. Medium and long-term hemodynamic results of the stent were so good that indications were broadened to native or complex right ventricular outflow tracts...
