Ventricular Arrhythmias in Patients Undergoing Mitral Valve Surgery
Study objectives: To assess the impact of mitral valve surgery for mitral regurgitation on ventricular arrhythmic burden and surrogate markers of fibrosis in patients with arrhytmogenic mitral valve prolapse (MVP) from baseline to 6 months after surgery To characterize the molecular landscape of arrhytmogenic MVP Study design: -Prospective explorative observational …
Clinical and Healthcare Economic OutcoMes From ReAl-worlD Use in Europe of an AI Software During AF Ablation
The goal of this Observational Prospective Multi-center Study is to observe the acute and long-term safety and performance outcomes after spatiotemporal dispersion-based AF/AT ablation utilizing the Volta Medical AI software in "real-life" clinical practice, without any imposed clinical workflow. Moreover, this study will allow to collect medico-economic data related to …
Image-Based Prediction of Ventricular Tachycardias in Post-Myocarditis Patients: an International Multicenter Case-control Study
Ventricular arrhythmias (VAs) are frequently associated with structural heart diseases (SHD) such as myocardial infarction, myocarditis, and non-ischemic cardiomyopathies. Myocardial fibrotic tissue plays a central role in the genesis and the maintenance of re-entrant VAs associated with post-myocarditis sequelae and late gadolinium enhancement cardiac magnetic resonance (LGE-CMR) has proven to …
New Onset of Arrhythmia After Patent Foramen Ovale (PFO) Closure
Embolic stroke of undetermined source (ESUS) accounts for approximately 25% of all ischemic strokes, with patent foramen ovale (PFO) considered a major mechanism behind ESUS. When specific anatomic criteria are met, transcatheter PFO occlusion is regarded as the gold standard for secondary stroke prevention. However, previous studies have shown that …
Arrhythmias in Pulmonary Hypertension Assessed by Continuous Long-term Cardiac Monitoring
Arrhythmias are considered a prominent phenomenon in pulmonary hypertension (PH) as the disease progresses. According primarily to retrospective studies with up to 24 hours of monitoring, supraventricular tachycardias (SVT) can be found in 8-35% of patients, with significant impact on survival. Furthermore, a few prospective studies to date deploying short-term …
Hybrid Score to Predict OTVA-SOO in Patients with Wide Basal QRS
Outflow tract ventricular arrhythmia (OTVA) is the most common type of ventricular arrhythmia, and catheter ablation (CA) is the primary treatment option for patients experiencing symptoms. Accurately identifying the origin site of OTVA is essential for effective catheter ablation, minimizing procedural risks, and enhancing treatment success. However, most studies that …
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 …
