Filter by:The number of patients with implantable pulse generator (IPG) has steadily increased in Japan causing increment in number of in office follow-ups and greater burden on many hospitals. The purpose of this multicenter randomized study is to demonstrate that BIOTRONIK Home Monitoring system reduces office follow-up visits without compromising patient safety.
Pacing leads are key elements of a pacing system as their proper functioning is one of the major factors affecting the long term performance of the whole system. Success of a pacing lead implant can be defined considering 3 items: ease of lead implant, lead stability and lead electrical performances. These factors may be related to the physician experience (global implant experience, experience with a given lead), to the implant procedure (lead access, lead position, implant time, scopy time) to the lead (handling and mechanical characteristics) and to the patient (ischemic history). Even though implant success rate is quite high with currently available leads, the weight of the different factors influencing success has never been studied systematically. The objective of the current study is then to define the predictive factors of an implant success with the CapsureFix MRI model 5086. This lead has been selected because it has been available for a short period, so the investigators have a limited experience of it and it has a unique design which makes it conditionally safe in an MRI environment and which may be associated with specific handling characteristics.
The technological progress allowed the development of more and more sophisticated pacemakers, widening the therapeutic indications but also meeting the physiological needs of the patient. This progress led to a more and more complex programming for the physicians. To help them set optimally the pacing parameters, physicians refer to the existing recommendations of learned societies as well as to his expertise. Manufacturers developed also algorithms integrated into pacemakers with the aim of assisting physicians in their programming. TherapyGuide is a function which proposes a programming adapted to the psychopathological state of the patient, with a justification based on experts' consensus, clinical studies as well as on published articles. Physicians have the choice to accept or reject the programming proposed by TherapyGuide. When rejected, there is no means to analyze the modifications brought to the proposed set of parameters. The nature, the frequency and the reasons of these modifications are not thus known. The purpose of this study is to assess the acceptance of the TherapyGuide proposals by physicians and to identify the most frequent type of programming changes they make and their rationale.
Understudied drugs will be administered to children per standard of care as prescribed by their treating caregiver and only biological sample collection during the time of drug administration will be involved. A total of approximately 7000 children aged <21 years who are receiving these drugs for standard of care will be enrolled and will be followed for up a maximum of 90 days. The goal of this study is to characterize the pharmacokinetics of understudied drugs for which specific dosing recommendations and safety data are lacking. The prescribing of drugs to children will not be part of this protocol. Taking advantage of procedures done as part of routine medical care (i.e. blood draws) this study will serve as a tool to better understand drug exposure in children receiving these drugs per standard of care. The data collected through this initiative will also provide valuable pharmacokinetic and dosing information of drugs in different pediatric age groups as well as special pediatric populations (i.e. obese).
Bradyarrhythmia, including sinus node dysfunction and atrioventricular block, is a major cause necessitating pacemaker implantation. In contrast to familial bradyarrhythmia known as by mutations at particular ion channels, limited information is available for the mechanistic study in non-familial bradyarrhythmia. Possible gene polymorphisms related to non-familial bradyarrhythmia were studied. Comparison of multi-locus analysis and single-locus analysis will be analyzed between the cases and controls. Functional studies will perform to clarify the results of association study.
The purpose of this Post-Approval Study (PAS) is to demonstrate the chronic performance of the SureScan pacing system when used in an MRI environment according to product labeling. This study is required by the Food and Drug Administration (FDA) as a condition of product approval.
The purpose of this study is to determine whether the use of laryngeal mask classic as method for securing the airway in the population of 2 years to 14 years is associated with risk of laryngospasm as compared with the use of endotracheal tube.
The intent of this study is to evaluate the performance of the implanted Accent MRI TM system in a clinical setting and optionally in the MRI environment. This system includes the St. Jude Medical Tendril MRI™ lead and SJM Accent MRITM DR pacemaker. Also the MRI Activator™ will be evaluated in this study. The MRI Activator is a handheld device that allows the user to enable and disable MRI Settings as well as check the status of MRI Settings in the pacemaker. The patient population under study includes patients with a standard bradycardia pacing indication.
The application scenario is shown in the figure below: the user utilizes an ECG-based wireless sensor (WiBoC Chipset), and transmit those signals to a mobile-phone device that has an embedded expert system integrated. With the aid of 3G system, a remote healthcare monitoring center receives those uploaded signals and stores into the application server. According to the events from this server, the people on service responses to the emergency and takes the corresponding process.
Primary Objective: To characterize left ventricular (LV) threshold behavior over time using daily left ventricular capture management (LVCM) measurements. Study Design: This is a multicenter, prospective, non-interventional study with patients receiving their first cardiac resynchronisation therapy-implantable cardioverter defibrillator (CRT-ICD) device. The study design, based on the primary objective, is an observational examination of LV thresholds over time. Daily left ventricular threshold measurements will be collected using the LVCM feature. Up to 150 patients will be enrolled in Canada to evaluate the primary objective at up to 15 study centers. Data will be collected at Baseline, Implant, 12 months post-implant and all regularly scheduled follow-up visits up to 12 months post-implant. Devices: The ConcertoTM CRT-ICD device and future Medtronic CRT-ICD devices containing the LVCM feature will be used in this study.
