Filter by:This study will evaluate the feasibility of visualization and characterization of arrhythmia ablation lesions by MRI immediately following standard ablation techniques. The appearance of the ablation lesion will be correlated with clinical outcomes and risk of arrhythmia recurrence.
This Study is designed to determine the outcome and effect of implementation of Esophageal Stylet as a strategy to minimize the risk of esophageal injury during the atrial fibrillation catheter ablation procedure.
The main aim of this study, which was carried out in two parallel groups, is testing the efficacy of a specific micronutrients combination in adults with heart rhythm disturbances and accompanying symptoms. It is therefore the investigators hypothesis that daily oral administration of the specific micronutrients combination will lead to a decrease of symptoms awareness and to a reduction of heart rhythm disturbances in adults with or without structural heart disease. The principal endpoints will be a decrease in the total score of symptoms awareness.
The goal of this registry/observational study is to collect data on the clinical utility of MediGuide™ system in cardiac resynchronization therapy (CRT) implantation and electrophysiology (EP) procedures.
This study will validate the recording accuracy of a specific electrical interval of the heart, the QT interval, between an iPhone rhythm strip recording and a traditional 12-lead electrocardiogram (ECG). These measurements will occur in hospitalized patients that are starting either sotalol or dofetilide, since both of these medications can prolong the QT interval.
This is a single-center, randomized controlled trial study design. Enrolled participants have a cardiovascular condition for which they are undergoing implantable cardioverter defibrillator (ICD) therapy and comorbid insomnia. Participants were randomized to a behavioral intervention for insomnia in ICD patients or a waitlist control. The treatment intervention period lasted 4 weeks with a telephone booster session administered at 3 month follow-up. The objective of the study is to examine the impact of a brief therapy combining established behavioral approaches to treating insomnia with novel components to target negative cognitions and anxieties associated with cardiac disease and ICD implantation. Primary patient outcomes include sleep, psychological functioning, daytime functioning, cardiac functioning, cognitive performance, and ICD adjustment.
ZipLine Medical, Inc. has developed a novel, non-invasive skin closure device called "Zip Surgical Skin Closure" to replace sutures, staples and glue for closure of the skin layer for surgical incisions or laceration repair. The study will be comparing the Zip Surgical Skin Closure to standard sutures in patients undergoing cardiovascular implantable electronic device (CIED) procedures on outcomes including closure time, cosmetic appearance of resulting scar, and overall cosmetic appearance of scar. The study will be following participants for 3 months following CIED procedure.
This is a prospective clinical trial to determine the optimal QLV interval during implantation to achieve the best possible response from cardiac resynchronization therapy for heart failure patients.
This is a randomized, prospective clinical trial to determine the effects of two different pacemaker atrioventricular delay (AV delay) settings on heart function in patients with dual chamber pacemakers implanted for symptomatic bradycardia with long PR intervals (delayed conduction between upper and lower chambers of the heart). The study will compare a long, fixed AV delay (standard) with an optimized AV delay for each individual using echocardiography (experimental).
The objective of this study is to evaluate myocardial injury, if any, as quantified by cardiac markers (Troponin-T) in defibrillation threshold (DFT) testing during implantation of implantable cardioverter defibrillators (ICDs) using the upper limit of vulnerability (ULV) method vs. standard defibrillation threshold method.
