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 …
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 …
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 …
Examination of Fibrillation Atria Using Magnetic Resonance Imaging and Endocardial High-density Mapping
Cather ablation of non-paroxysmal atrial fibrillation is less effective compared to paroxysmal atrial fibrillation. Therefore, new techniques have been developed, such as high-density mapping to determine areas of focal and rotational activities. The aim is to assess the clinical efficacy of ablation focal and rotational activities, and to assess the …
Lifetech LAmbre™ Left Atrial Appendage Closure System Post-Market Registry
Single-center, single-arm, prospective, post-market study of LAmbre™ LAA Closure System. To evaluate immediate and long term procedural success of Lifetech LAmbre™ occluders in patients.
Combining Left Atrial Appendage Closure With Cryoballoon Ablation in Chinese Population
Cryoablation combined with left atrial appendage closure is a novel strategy for atrial fibrillation patients. Through long-term follow-up, the investigators aimed to observe the safety and efficacy of the combined procedure in Chinese population.
cOncomitant Left Atrial aPpendage Closure and Pulsed Field ablaTION-Asia
Subjects enrolled in the OPTION-A study will be clinically indicated for atrial fibrillation (AF) ablation procedure with the FARAPULSE™ PFA system and treatment with WATCHMAN LAAC Device, per physician's medical judgement and according to hospitals' standard of care during the same procedure.
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.
COCONUT Study Concomitant PVI and LAAC
In patients with non-valvular AF, at high stroke risk, and who are ineligible for long-term oral anticoagulation LAAC could be an alternative to anticoagulation and safety and efficacy has been shown in several studies and registries.8 While PVI and LAAC are both conducted in the left atrium and share the …
