Filter by:This study will compare aggressive antiarrhythmic therapy to catheter ablation for ventricular tachycardia in patients who have suffered prior myocardial infarction. The purpose of this study is to evaluate the optimal management of patients presenting with recurrent VT and receiving ICD therapy in spite of first-line antiarrhythmic drug therapy. The hypothesis is catheter ablation is superior to aggressive antiarrhythmic drug therapy for recurrent VT.
Primary objective is to evaluate the safety and performance of the implanted Subcutaneous implantable cardioverter defibrillator (S-ICD) system. A maximum of 10 subjects were to be enrolled and followed for one month to collect data on the safety, efficacy, and performance of the implanted S-ICD system. Additionally, patient comfort will be assessed as will cosmetic outcome.
This is a prospective, non-randomized, multi-center clinical case series evaluating the outcomes of the magnetic navigation system in ventricular tachycardia (VT) cases. Subjects will be evaluated acutely and will be followed clinically at 1, 6 and 12 months post-treatment.
This prospective, randomized, single blind, multi-centre study will examine the effect of the right ventricular (RV) lead location in patients implanted with a cardiac resynchronization defibrillator. 1. Purpose : To compare the effect of RV mid-septal (RVS) versus RV apical (RVA) lead location on left ventricular reverse remodeling in patients indicated for cardiac resynchronization therapy device (CRT-D) over a period of 6 months and to evaluate the clinical outcome of the RVS versus RVA pacing, over a period of 12 months. 2. Objectives: The primary objective is to demonstrate that there is no difference between the two groups (RVA vs. RVS) in the change of left ventricular end systolic volume (LVESV), between baseline and 6 months. The secondary objectives are to evaluate the percentage of "echo-responders" plus additional clinical and safety outcomes. This prospective, randomized, multi-centre, single-blind with 2 parallel arms, non-inferiority study will be conducted in approximately 25 study centres in Europe. The patients will be randomized in a 1:1 ratio. A maximum of 416 patients will be enrolled in this study. All eligible patients will be followed through baseline, randomisation, pre discharge, 1, 6 and 12 months post-implant. Enrolment is expected to be completed in 18 months. The total duration of the study is expected to be approximately 30 months.
The purpose of this observational study is to collect data regarding the population of patients implanted with St. Jude Medical ICD.
This trial will assess the safety of defibrillator testing and the influence of defibrillation testing on the efficacy of clinical shocks. The trial will test the hypothesis that implantable cardioverter defibrillator (ICD) implantation without defibrillation testing (DT) is non-inferior to implantation with testing against the composite endpoint of ineffective first appropriate clinical shock or arrhythmic death. It will also test the hypothesis, that defibrillation testing increases the peri-operative (30 days) complication rate of ICD implantation.
The RAPTURE Study will determine whether dual chamber defibrillators with atrial prevention and termination therapies, minimized ventricular pacing, and remote monitoring will reduce the rate of inappropriate shocks and improve quality of life compared to optimally programmed back-up pacing only single chamber ICDs when used for primary prevention of sudden cardiac death
This clinical trial is a multi center, prospective, randomized, parallel study designed to compare septal to apical ICD lead placement.
This pilot study is to prospectively evaluate the benefit of clinicians being able to access ICD device information in a timelier manner and treat fluid overload with a pre-defined pattern using the Medtronic OptiVol, Medtronic CareAlerts and Medtronic CareLink in Conexus-enabled devices (remote arm) as compared to the same devices without Medtronic OptiVol, Medtronic CareAlerts and Medtronic CareLink available to the treating physician (standard arm).
The purpose of this evaluation is to assess the acceptance level of specific programming recommendations based on the patient's clinical needs and primary indications when using the feature 'Indications Based Programming' (IBP) available in the ZOOMVIEW Software Application for the TELIGEN DR / VR and COGNIS family of devices compared to daily life programming chosen by physicians.
