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 …
Progression of Atrial Fibrillation in the Young
The purpose of this study is to investigate the presence and magnitude of structural changes of the heart and their long-term development in young patients with atrial Fibrillation (AF), studied by echocardiographic measurements and plasma biomarkers and their association to AF burden, studied using long-term ECG
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 …
Prospective Phenotyping for Genetic Subtypes of Early-onset Atrial Fibrillation
This is a prospective, case-control study that seeks to learn about the role of genetics in early onset atrial fibrillation (AF) and if genetic testing can be used to improve how the investigators treat atrial fibrillation. The study will enroll 225 participants. Eligible participants will have undergone sequencing for arrhythmia …
The CoAGulation Biomarkers and Atrial Fibrillation (COAG-AF) Pilot Study
The aim of the Correlation Of CoAGulation-Atrial Fibrillation (COAG-AF) study is to prove that an increase in pro-thrombotic biomarkers in AF is associated with an increase in AF burden. Secondary objectives of the study are the following: To investigate the impact of catheter ablation on serum pro-thrombotic biomarkers in patients …
Contribution of Computed Tomography and Cardiac-MRI in Atrial Fibrillation Ablation
Atrial fibrillation ablation (AF) is a standard interventional treatment for patients with symptomatic AF refractory to medical treatment. The known predictive factors for the success of the procedure remain insufficient to predict the probabilities of success and to appropriately select the patients who could benefit the most from this procedure. …
Atrial Fibrillation in Young Patients: a Prospective Multicentre Registry
Atrial fibrillation is a rare cardiac arrhythmia in young (i.e. <= 35-year-old) patients. Etiological factors, current management and mid- to long-term outcomes remain unknown.
Application Value of Whole-procedure Optimization for Catheter Ablation of Atrial Fibrillation
The success rate of single-procedure atrial arrhythmia-free survival particularly ranged from 40% to 66% in persistent AF ablation. However, The surgical Cox maze III procedure has been established to be an effective curative strategy for AF with an AF-free survival rate of more than 95%. The main reason is the …
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 …
