Filter by:A single-center registry to prospectively evaluate the safety of non-cardiac/non-thoracic magnetic resonance imaging (MRI) in patients with implanted cardiac devices (pacemakers and implantable cardioverter defibrillators).
The purpose of the registry is to accumulate pre-and post-scan device interrogation data for the purpose of determining the risk of MRI for patients with implantable devices.
The purpose of the registry is to evaluate an organizational model fixing roles and behaviors of subjects involved in the remote monitoring of patients implanted with pacemakers and defibrillators. The evaluation will estimate the clinical efficiency and the impact on health service resources of the organizational model when this is implemented in the daily clinical practice.
Pacemaker technology is constantly evolving. In the past 10 years, numerous advancements have been made in pacemaker therapy, diagnostics and connectivity. These advancements include automated capture, automated sensing, patient alert functions, algorithms minimizing ventricular pacing, automatic mode switching in response to atrial tachyarrhythmia, rate responsive pacing, advanced diagnostic features, remote monitoring and radiofrequency (RF) technology. However, little information is available on how these new features are being utilized by physicians in the real world and how these features impact patient outcomes. This observational study will gather data on the patients' presenting clinical status, indication for device implantation, utilization of advanced device features, device therapy choices, clinical management and outcomes in a general pacemaker population. The primary aim of the study is to evaluate the usage of advanced features and diagnostics in patients with St. Jude Medical pacemakers. The secondary aim of the study is to learn more about the progressive clinical outcomes in the general pacemaker patient population. The tertiary aim of the study is to evaluate the correlation between the usage of advanced features in pacemaker patients and the patient's clinical outcomes.
The primary objective of this study is to evaluate the efficacy of the automated data collection in the Zephyr device as compared to manual testing results for atrial and ventricular pacing thresholds. The secondary objectives include: to compare the in-clinic time needed to retrieve and document the automated device measurements for all tests to the additional time needed to manually measure sensing, impedance and thresholds for the same patient; to compare the accuracy of the automated device test results to manual testing results; evaluate the percentage of patients who are recommended for ACapTM Confirm utilization. The Primary Hypotheses are: 1. The values reported from ACapTM Confirm will be within 0.125 V of the value that is obtained manually in clinic. 2. The values reported from VentricularAutoCaptureTM will be within 0.125 V of the value that is obtained manually in clinic.
The specific aims of the patient intervention are to: 1. increase patient knowledge about pacemakers (PM) and implantable cardioverter-defibrillators (ICDs) 2. help patients to identify if their PM or ICD has been interrogated 3. improve patient's physician-patient communication skills 4. teach patients how to identify if their device has been recalled 5. train patients what to do in case of a device recall The educational interventions proposed, if proven to be effective by this pilot, will provide a low-cost, reproducible intervention to improve the clinical care and safe management of pacemakers (PM) and implantable cardioverter-defibrillators (ICD) in patients. The goal of the intervention will be to promote the safe use of implantable pulse generators.
The purpose of this study is to evaluate the potential clinical and economic benefits of using CareLink remote management for pacemaker follow-up. Study Objectives include: 1. To determine clinician perceived quality of care for CareLink remote follow-up. 2. To determine patient satisfaction with CareLink follow-up. 3. To estimate the time required to perform patient follow-up via CareLink remote transmissions. 4. To determine the percentage of regular CareLink follow-ups that do not require further in-clinic review of the patient. 5. To estimate potential patient cost avoidance for one year of follow up incorporating CareLink. 6. To evaluate compliance to scheduled CareLink transmissions with the remote management system This is a non-randomized, multi-center, prospective study in which 120 patients who have a pacemaker are enrolled into the study and receive a CareLink monitor. Patients will replace their regularly scheduled pacemaker clinic follow-up visits with a CareLink remote transmission for 12months. Patients will require a test transmission within 1 month after they receive their CareLink monitor. Afterwards, patients are followed via CareLink transmissions as per their usual clinic schedule for 12 months.
The new NcIQ thoracic impedance monitor is based on the predicate device, the IQ101. The new model uses the same 3-dimensional signal averaging as the original device, but also include second radio frequency signal to permit the device to work “wirelessly”, i.e., without electrode lead attachments to the patient. This study seeks to 1) validate the use of the new device and confirm the correlation of the IQ101 and NcIQ. 2) Evaluate the ease of the new device. The new IQ2 thoracic impedance monitor is based on the predicate device, the IQ101. The new model uses the same 3-dimensional signal averaging as the original device, but with smaller housing and updated operating software. This study seeks to 1) Validate the use of the new device and confirm the correlation of the IQ101 and IQ2. 2) Compare the ease of the devices.
The purpose of this study is to evaluate the exercise capacity of patients with complete heart block who are chronically being paced from the right ventricle. Also, we hope to correlate the level of uncoordinated contraction with the patients exercise capacity. We will enroll patients with complete heart block as diagnosed by standard electrocardiographic means and now have a permanent pacemaker. All patients we approach for this study will receive an echocardiogram to assess their heart function. As part of the echocardiogram, they will also receive a Tissue Synchronization Imaging (TSI) evaluation to assess the level of uncoordinated contraction they have. The patients will then be subjected to a cardiac exercise stress test which will involve them running on a treadmill until they cannot continue while data is collected regarding their heart's response to exercise. All portions of the study are noninvasive, which means they work from probes and monitors outside the body.
Pacemakers are implantable devices that pace (electrically stimulate) the heart. Some pacemakers have special programs to treat irregular atrial rhythms(top chambers of the heart beat too fast or too slow). Advances in pacemaker technology in recent years include features that automatically adapt to patient conditions without intervention from the clinician. Adapta (Model #ADDR01) is a new pacemaker that is designed to provide further automaticity advances by including the managed ventricular pacing (MVP) feature designed to promote intrinsic conduction (natural flow of electricity in the heart) by reducing unnecessary ventricular (lower chamber of the heart) pacing (electrical impulses). Adapta also contains a feature called TherapyGuide that is designed to allow the user to select certain conditions for each subject and receive a list of suggested pacemaker parameter value changes based on those conditions. The purpose of this study is to evaluate the overall system safety and clinical performance of the Adapta pacing system.
