Upregulating the Nitric Oxide Pathway To Restore Autonomic Phenotype (UNTRAP).

20 participants enrolled at the University Hospitals of Leicester NHS Trust will be invited to take a beetroot juice supplement, which naturally contains a high concentration of nitrates, and a nitrate-free (placebo) beetroot supplement. In a double blind way, participants will be randomised to the order in which they receive ...

Phase N/A

Fetal Growth and Pregnancy Complications Among Women With Heart Disease

Heart disease is about to become the most important cause of maternal deaths in industrialized countries. In addition, heart disease in pregnancy is associated to an increased rate of fetal growth restriction, premature birth, preeclampsia and other pregnancy complications for the mother and the baby. As many women with congenital ...

Phase N/A

ATrial Tachycardia PAcing Therapy in Congenital Heart

University of Iowa is moving to begin the multi-institutional portion of this study by asking for centers to assist with enrollment so that the investigators can meet our enrollment goal. The investigators wish to recruit a minimum of 250 subjects and will collect data for up to 300 subjects. The ...

Phase N/A

VF Mapping in Brugada and Early Repolarization Syndromes

The investigators will study symptomatic BrS and ERs syndrome (N=25) and asymptomatic patients (N=25) age between 16-70 years old to determine values and limitations of non-invasive mapping using electrocardiographic imaging (ECGI) in identifying VF substrates as target sites for catheter ablations in patients with Brugada (BrS) and Early repolarization syndromes ...

Phase N/A

Incidence of Ventricular Arrhythmias in Patients With Chronic Total Occlusion Recanalization

Rationale: Successful chronic total occlusion (CTO) recanalization has been associated with improved long-term survival. Furthermore, CTO is an independent predictor for the occurrence of ventricular arrhythmias (VA) in patients with ischemic cardiomyopathy and implantable cardioverter defibrillators (ICDs). One may speculate that a successful CTO recanalization may provide electrical stability. However, ...

Phase N/A


This is a prospective, multi-center, non-randomized, observational registry study of STEMI patients that undergo CMR examination. Information of other cardiac imagings and clinical outcomes are also prospectively collected in the database. This project will establish a prospective registry of 1000 STEMI patients in 10 sites with follow-ups of up to ...

Phase N/A

His Bundle Pacing Registry

The HBP Registry will be conducted to gain a deeper understanding of the HBP device implant and follow-up workflows. Additionally, the registry will provide a broader understanding of the clinical utility in mapping the His bundle with the use of Abbott's EnSite Precision Cardiac Mapping System with an electrophysiology catheter ...

Phase N/A


60 patients with persistent AF will be randomized 1:1 between Cryoballoon ablation and Radiofrequency ablation in the FIRE AND ICE II Trial Pilot at 4 clinical sites in Europe. The data collected within the pilot phase will be reviewed and a decision on extending the trial with an extended number ...

Phase N/A

Comparison of 24-hour Holter Monitoring Versus 14-day Continuous ECG Patch Monitoring EZYPRO

This is an open-label study to investigate the functional features of prolonged monitoring by 14-day EZYPRO to improve the medical care and/or diagnosis for the patient with arrhythmia. Patients will be enrolled by outpatient basis from two clinical study sites. Enrolled patients will wear a traditional 24-hour Holter monitor and ...

Phase N/A

Heart Rate Variability and Cognitive Load on Image-Based Virtual Reality Instructional Design in Otolaryngology

Background: Workplace-based assessments, such as mini-clinical evaluation exercise (mini-CEX), direct observation of procedural skills (DOPS), and milestones, target the highest level of clinical competence and collect information about doctors' performance in their normal practice. Recent advances in virtual reality (VR) simulation, lowering the complex of learning task and the cognitive ...
