Registry of Atrial Arrhythmia Ablation Procedures Using Pulsed Field Ablation in Poland
The aim of the described project is to establish a multicenter, nationwide registry of atrial arrhythmia ablation procedures using the Pulsed Field Ablation (PFA) method. These procedures have only recently begun to be performed in several centers across Poland. With proper coordination of the registry, this will enable the consolidation …
Evaluation of Exercise Testing and Physical Activity in Children and Adolescents Living With Inherited Arrhythmias
The goal of this observational study is to evaluate exercise testing and daily physical activity in children and adolescents who are diagnosed with an inherited arrhythmia. The main question it aims to answer is: Does maximum heart rate during controlled exercise tolerance testing accurately reflect maximum heart rate and peak …
Baseline Atrial Fibrosis Predicts Risk for Post-operative Atrial Fibrillation in Patients Undergoing Cardiac Surgery
The study aims to evaluate and compare the incidence of atrial arrhythmias (including Post-Operative Atrial Fibrillation (POAF), atrial flutter, and atrial tachycardia) stratified by baseline Utah fibrosis stages and overall fibrosis (%) of the left atrial wall area. The investigators hypothesize that patients with a higher baseline Utah fibrosis staging …
Image-Based Prediction of Ventricular Tachycardia Events in Non-ischemic Cardiomyopathy
Risk stratification for sudden cardiac death (SCD) in patients with non-ischemic cardiomyopathy (NICM) remains suboptimal. Although current guidelines rely on severe left ventricular systolic dysfunction (left ventricular ejection fraction (LVEF) < 35%) as key predictor of arrhythmic risk and clinical indication of prophylactic implantable cardioverter defibrillator (ICD), this approach seems …
Pathophysiologic Mechanism for Arrhythmias and Impaired Aerobic Capacity in Tetralogy of Fallot and Other Congenital Heart Diseases
This study is being done to determine the mechanism(s) contributing to the onset of symptoms (i.e. shortness of breath and/or palpitations) as well as changes in heart structure in patients with congenital heart disease (CHD)
Percutaneous Left Stellate Ganglion Block In Out-of-hospital Cardiac Arrest Due to Refractory VEntricular Arrhythmias (LIVE Study)
A prospective uncontrolled study to verify the feasibility and practicability of percutaneous stellate ganglion block (PSGB) in patient suffering from a refractory out-of-hospital cardiac arrest (OHCA) due to a shockable rhythm and the eventual occurrence of complication related to it. The study will also assess whether the rate of return …
GEAM Study Aims At Assessing the Role of Genetic Testing in Patients with Arrhythmic Myocarditis.
This study aims to answer multiple unsolved questions in the field of arrhythmic myocarditis. Improving the diagnostic work-up. While endomyocardial biopsy (EMB) and cardiac magnetic resonance (CMR) constitute the gold standard diagnostic techniques for myocarditis, the role of genetic testing is still unclear. Identifying the subset of patients with CGVs, …
ATrial Tachycardia PAcing Therapy in Congenital Heart
Congenital heart disease (CHD) affects approximately 1% of newborns in the US, with 25% of those affected having critical conditions requiring open heart surgery within one year of birth. Surgical and medical advances have allowed many patients to live beyond their fourth and fifth decades of life. Unfortunately, cardiac arrhythmias …
Flecainide in Idiopathic Premature Ventricular Contractions and Related Cardiomyopathy
The UNIFLECA study is a prospective, single-arm, observational cohort evaluating the efficacy, safety, and tolerability of flecainide (in the form of Sanocard) in adults with frequent idiopathic premature ventricular contractions (PVCs) and suspected PVC-induced cardiomyopathy (PVCi-CMP). Frequent PVCs-defined as a burden >5% on two separate 24-hour Holter recordings-are increasingly recognized …
Pacemaker-based Long-term Monitoring of Sleep Apnea
This is a prospective, non-interventional cohort study. It tests the hypothesis that Pacemaker-derived monitoring of sleep-related breathing disorders and/or daily physical activity predicts clinical outcome. Autonomic imbalance defined by an increased periodic repolarisation dynamics (PRD) predicts clinical outcome in pacemaker patients. Autonomic imbalance defined by an increased periodic repolarisation dynamics …
