Prospective Evaluation of CT Guided Ablation of Cardiac Ganglionated Plexi
Despite progress made in treating atrial fibrillation with catheter ablation, outcomes remain suboptimal with pulmonary vein isolation alone. Ablation of ganglionated plexi (GP) has been shown to be beneficial in patients with atrial fibrillation although optimal strategies of localization of these regions have yet to be determined. The investigators aim …
Endocardial Mapping of Left Atrium for Evaluation of Concomitant Surgical Ablation Lesions
Concomitant ablation is an effective treatment for patients with various types of atrial fibrillation undergoing heart surgery. However, recurrences of tachycardias after concomitant ablation can happen and seem to be mostly related to reentry mechanism resulting in atrial tachycardias. The aim of the study is to perform invasive re-mapping of …
Biomarkers in Pulsed Field Ablation Versus Cryoballoon Ablation
Our study will include consecutive patients undergoing pulsed field ablation (PFA) or cryoballoon (CBA) ablation. Tissue injury and inflammation markers will be measured before and after the procedure.
Left Atrial Appendage Occlusion With The Amplatzer Amulet Device: The Southeast Asia Observational Study
This is a prospective and retrospective, multicenter observational study where the study is being performed to explore on the short-term and long-term safety and efficacy of LAA occlusion with Amplatzer Amulet Device in Southeast Asia population on a real-world basis.
An Investigator-initiated Linked Study to OCEANIC-AF
Impaired endogenous fibrinolysis is a recently recognised risk factor for thrombotic events in patients with cardiovascular disease. Enhancing endogenous fibrinolysis in such individuals represents a way of reducing thrombosis risk. However, the optimal pharmacotherapy to enhance fibrinolysis is unclear. The aim of this study is to assess the effect of …
Prospective Study to Validate Ablation Parameters With MRI Based Scar for Left Atrial Ablation
One of the goals of an ablation procedure is to create scarring of cardiac tissue. Not all ablations result in scar tissue. Advances in technology have improved scarring but ideal parameters that result in scar tissue are still not completely clear and there is great variability in the parameters used. …
Heart Rate Variability After Ablation
Pulsed-field catheter ablation is a promising new treatment method for patients with atrial fibrillation. The mechanism of cell damage here is different from that of classic catheter ablation, in which the ganglion plexuses around the pulmonary veins are also damaged and thus changes in the autonomic nervous system occur. The …
Clinical and Healthcare Outcomes From Real-World Use in the United States of a Companion AI During AF Ablation
Observational, multi-center, clinical device registry for US patients with a primary goal to observe the clinical outcomes in patients who are mapped with Volta Medical's VX1 or AF-Explorer systems during AF ablation procedures.
Interest of a Hybrid Connected Watch for Cardiac Rhythm Monitoring in Post-operative Cardiac Surgery
The objective of this single-center pilot study is, with the help of a connected watch, to show the absence of recurrence or maintenance of sinus rhythm in patients with a Post Operative Atrial Fibrillation (POAF) and to help treating cardiologists in the care of these patients.
Diagnostic Approach of Early Atrial Fibrillation, Silent Stroke and Cognitive Disorder in Patients With High-risk
The goal of this observational study is to determine the impact of the combined use of cardiac rhythm recording devices, biomarkers, echocardiogram, and Magnetic Resonance Imaging (MRI) on the early detection of AF, silent stroke, and cognitive impairment in subjects older than 65 years at high risk. The main questions …
