Filter by:Prospective, non-randomized, multi-center, international study designed to evaluate the safety and effectiveness of the Aveir™ Dual-Chamber (DR) Leadless Pacemaker system.
The purpose of this research study is to assess the implant success proportion of the Medtronic SelectSecure MRI SureScan Model 3830 pacing lead at the bundle of His for His bundle pacing.
The purpose of this study is to collect clinical data for the development and evaluation of a new device feature for automatic AV-delay (AVD) optimization.
The purpose of the Advisa MRI System clinical study is to confirm safety and effectiveness in the clinical MRI (Magnetic Resonance Imaging) environment when subjects receive MRI scans up to 2W/kg Specific Absorption Rate (SAR) without positioning restrictions (MRI scans may occur anywhere on the body including the chest).
This study will enroll all patients who will attend an in-hospital follow-up of cardiac device since February 22nd 2010 to June 21st 2010. Primary objective of the study is to observe how many of patients seen during these period (approximately 5000) will receive a change in cardiac device programming or in drug therapy or a scheduled or urgent hospital admission. These data should help to clarify how useful and safe is a remote monitoring strategy for this kind of patients.
Magnetic fields may interfere with the function of cardiac pacemakers. A magnetic drape to hold surgical instruments is widely used in surgery. The use of this drape on pacemaker patients has not yet been tested. Our objective is to conduct a clinical study to evaluate the potential interference of the surgical magnetic drape on patients with cardiac pacemakers. We are testing the magnetic drape on forty patients in the pacemaker clinic. The totality of the drape is applied over the pacemaker and depending on the result, the drape is either folded in two over the pacemaker or the magnets are applied individually up to the totality of the drape, 70 magnets. Thereafter, the drape is pulled in increments of 3 cm caudally until the interference is ceased. Results are in process as we are presently actively recruiting.
The purpose of the Optimize RV study is to determine the long-term effect of selective site pacing. Selective site pacing refers to which area of the right ventricle the lead is placed. The goal of select site pacing is to improve how the heart contracts when paced in the ventricle. By pacing in select sites, it is possible to better copy the natural pattern of contraction of the heart.
The objective of this study is to evaluate whether the heart rate variability, daily heart rate, and/or intrathoracic impedance recorded by implantable cardiac devices can be used in conjunction with other traditional clinical practice methods to determine if heart failure patients are ready for hospital discharge.
