Investigation of Cardioversion Versus Therapeutic Ablation for Persistent AF (ORBICA-AF)
The main aim of the research is to investigate whether patients undergoing pulmonary vein isolation with catheter ablation for persistent atrial fibrillation (AF) will have lower rates of AF recurrence than those treated by DC cardioversion without an ablation procedure.
Device-based Rate Versus Rhythm Control in Symptomatic Recent-onset Atrial Fibrillation (RACE 9 OBSERVE-AF)
Continuous heart rhythm monitoring elucidated the recurrent and transient nature of recent-onset atrial fibrillation (AF). The RACE7 ACWAS showed that a wait-and-see approach (WAS) in patients with recent-onset AF (rate control for symptom relief followed by delayed cardioversion if needed <48h) allows spontaneous conversion to sinus rhythm in 69% of …
Comparison of 3 RF Delivery Modes of the QDOT Catheter for Paroxymal Atrial Fibrillation (AF) Ablation
Pulmonary vein isolation is the main treatment of paroxysmal and persistent atrial fibrillation. The aim of our study is to prospectively compare the efficacy and safety of the 3 options of radiofrequency delivery with QDOT Micro™, with systematic use of catheter stabilization tools and tighter lesions
Pulmonary Vein Isolation (PVI) Combined With Renal Denervation (RDN) in Atrial Fibrillation (AF) and Hypertension (HTN)
The close relationship between the increase of sympathetic tension, AF, and HTN cannot be ignored. In addition, the significant failure rate of PVI (20-50%) in the treatment of AF makes it very necessary to explore the effect of RDN on AF. Therefore, this study aims to compare the effects and …
320-detector Computed Tomography to Assess Myocardial Extracellular Volume Fraction in Patients With Atrial Fibrillation Before AF Ablation.
This study explores the relationship between myocardial fibrosis and patient outcomes in Atrial Fibrillation (AF), specifically after catheter ablation. It aims to use Cardiac CT, an accessible tool, to measure left ventricular extracellular volume (ECV) as an indicator of fibrosis. The study will assess if higher ECV levels correlate with …
Remimazolam for Postoperative Atrial Fibrillation
Atrial fibrillation (AF) is the most common cardiac severe arrhythmia globally and is associated with an increased risk of mortality and morbidity, with a loss of 6.0 million disability-adjusted life-years worldwide in 2017, conferring 0.24% of total disability-adjusted life-years globally. Due to the absence of knowledge of AF pathogenesis, currently, …
The COLchicine and Atrial FIBrillation Trial
The purpose of this study to investigate the effects of colchicine on atrial fibrillation recurrence and vascular and cardiac function in patients with atrial fibrillation.
Post Intensive Care Unit Atrial Fibrillation
Atrial fibrillation (AF) is a common heart rhythm disorder in the intensive care unit (ICU). It can be precipitated by multiple factors but it is unclear whether AF persists after discharge from the ICU, and long term. This study will investigate whether AF recurs up to one year after ICU …
Colchicine After Electrocardioversion for Atrial Fibrillation
The purpose of this study is to investigate whether a 3 month treatment course of low-dose Colchicine decreases the recurrence of Atrial fibrillation (AF) after electrocardioversion (ECV) in patients with AF.
Lenient Rate Control Versus Strict Rate Control for Atrial Fibrillation. The Danish Atrial Fibrillation Randomised Clinical Trial
Atrial fibrillation is the most common heart arrhythmia with a prevalence of approximately 2% in the western world. Atrial fibrillation is associated with an increased risk of death and morbidity. The comparable effects of a lenient rate control strategy and a strict rate control strategy in patients with atrial fibrillation …
