Safety and Efficacy of the CoolCryo System for Cardiac Cryoablation in the Treatment of Atrial Fibrillation
The study involves endocardial cryoablation of the left and/or right atrium of the heart using the CoolCryo system as an adjunct to mitral valve surgery, with the aim of eliminating atrial fibrillation (AF), which is a common sequelae of mitral valve defects and is associated with an increased risk of …
Left Atrial Volume Changes Who Underwent Cardioversion and Recurrence of AF After RF Ablation in Persistent AF (SAFE-AF)
Electrical/pharmacological cardioversion improves structural remodeling of left atrium. We hypothesize that persistent atrial fibrillation (AF) patients with more significant left atrial size reduction after cardioversion have lower AF recurrence rates following radiofrequency ablation. The aim is to evaluate the relationship between changes in left atrial size 3 to 6 months …
The Role of hs Troponin I and NT-proBNP in Predicting Atrial Fibrillation in Patients With Permanent Pacemakers
The goal of this clinical trial is to answer the research question whether hs Troponin I and NT-proBNP have a role in detecting atrial fibrillation in patients with pacemakers. Objectives of the study: To survey some risk factors for atrial fibrillation in patients with permanent pacemakers. To determine the role …
Predicting Development of SCAF in Device Patients
Atrial fibrillation (AF) often starts with short episodes of rapid irregular heartbeats that are only detected by implanted pacemakers or defibrillators. Usually people don't know that they have these episodes. Over time, these episodes can happen more often and last for longer periods. In some people, the heart eventually remains …
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 …
Pharmacokinetics of Apixaban in Peritoneal Dialysis
Atrial fibrillation (AF) is fairly prevalent in patients with end stage renal disease (ESRD) with the prevalence estimated to be 3.8 - 27%. While it is reported that patient with peritoneal dialysis (PD) has a lower incidence of AF as compared to patient with haemodialysis (HD), the risk is still …
Evaluation of Ablation Lesions Using Cardiovascular Magnetic Resonance Imaging
Ineffective ablation lesions can cause arrhythmia recurrence after catheter ablation for cardiac arrhythmia. Ablation lesions can be created with various ablation energy modalities. This study uses cardiovascular magnetic resonance imaging to evaluate the ablation lesion characteristics of radiofrequency ablation, ultra-low temperature cryo ablation, and pulsed field ablation. The ablation lesion …
Post-marketing Clinical Study of the LAMBRE System for Left Auricle Closure
Atrial fibrillation (AF) is responsible for 15-20% of ischaemic strokes. These events are often caused by thrombus formation in the left atrium. Thromboembolic risk in AF is primarily prevented by oral anticoagulation. However, this drug-based approach has a number of limitations, the most important of which are compliance problems and, …
PulseSelect™ PFA Global Registry
The PulseSelect™ PFA Global Registry is a prospective, global, multi-center, observational post-approval study. Subjects will be treated with the PulseSelect™ PFA System and followed according to SOC.
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.
