Filter by:Post-operative atrial fibrillation (POAF) is commonly observed in patients post cardiac surgery without a previous history of atrial fibrillation (AF) or other arrythmias. It's associated with significant postoperative complications including infection, bleeding reoperation, increased hospital length of stay (LOHS) and mortality. Magnesium has been identified as a potentially interesting compound with easy access and low toxicity. Hypomagnesemia has been observed frequently immediately after cardiac surgery. Both reduction of abnormal atomicity of atrial myocardium and prolongation of the atrial refractory period caused by administration of magnesium may prevent AF. The POMPAE trial will analyse the effectiveness of MgSO4 versus placebo (double blind randomized trial) in the prevention of POAF after 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.
To compare the relative efficacy for calcium pre-treatment in decreasing incidence of drug induced hypotension after diltiazem administration for treatment of AFF with RVR. Null Hypothesis: There will be no difference between groups in incidence of hypotension after pretreatment with calcium prior to bolus of diltiazem.
SAFE-LAAC CKD Trial has been designed to gather data on the most optimal strategy of antiplatelet therapy after transcatheter left atrial appendage occlusion with Amplatzer or WATCHMAN device in patients with the end-stage renal disease treated with chronic haemodialysis or peritoneal dialysis
New onset atrial fibrillation is a common problem after cardiac surgery. The reported incidence after coronary artery bypass grafting (CABG) is 15-40%, 37-50% after valve surgery, and up to 60% after CABG and valve surgery. Post-operative atrial fibrillation (POAF) is associated with increase risk for stroke, increased length of hospital stay, increase risk of other new arrhythmias, increased need for pacemaker implantation, and increased mortality. Several interventions have been implemented in order to prevent post-operative atrial fibrillation including use of betablockers, sotalol, amiodarone, atrial pacing, and antioxidant vitamins. Despite these interventions (several carry risk of adverse effects) POAF remains common. Cardiac sympathetic innervation arises from the stellate ganglion. Stellate ganglion block (SGB) with local anesthetic agents (lidocaine or bupivacaine) can reduce sympathetic output to the heart with minimal side effects. This procedure has been successfully utilized in patients with medication refractory ventricular arrhythmias. In atrial tissue SGB has been shown to prolong atrial effective refractory periods, reduce atrial arrhythmia inducibility, and shorten atrial fibrillation duration in patients who have atrial fibrillation. Pre-operative SGB has been utilized to prevent post-operative radial artery spasm (when the radial artery was used a coronary bypass graft conduit). The investigators hypothesize that pre-operative SGB will reduce the incidence of post-operative new atrial fibrillation in patients undergoing cardiac surgery.
Recurrence rate remains high after radiofrequency ablation in patients with non-paroxysmal atrial fibrillation(AF). Prolonged use of anti-arrhythmic drugs (AAD) beyond the post-ablation blanking has been adopted as a solution but without sufficient clinical evidence. Dronedarone is an AAD valid to maintain sinus rhythm and has fewer side effect than other AAD for long-term use.We sought to investigate the effect of prolonged use of dronedarone on recurrence of non-paroxysmal AF patients beyond the post-blanking period within the first year after ablation.
Cardiovascular disease is the leading cause of death worldwide. Advanced cardiovascular imaging using Magnetic Resonance Imaging (MRI) has proven to be effective in providing gold standard myocardial tissue characterization. Moreover, the intrinsic advantage of MRI's lack of exposure to ionizing radiation is particularly beneficial. At the same time, blood work can be very useful in early detection of certain cardiomyopathy, such as amyloid. However, there is a lack of agreement of on which markers are the most sensitive. This multi-study will allow us the unique opportunity to form a more comprehensive understanding for various cardiovascular diseases. Our team has developed novel cardiac MRI techniques that leverages endogenous tissue properties to reveal a milieu of deep tissue phenotypes including myocardial inflammation, fibrosis, metabolism, and microstructural defects. Among these phenotypes, myocardial microstructure has proven to be most sensitive to early myocardial tissue damage and is predictive of myocardial regeneration. In this study, the investigators aim to further study the importance of cardiac microstructure revealed by MRI in patient and healthy population and compare this novel technology with conventional clinical biomarkers.
This is a three-arm, single-blinded, randomized, sham-controlled, nonsignificant risk study to assess the feasibility of reducing Atrial Fibrillation burden with peripheral nerve stimulation. The three arms include treatment with a wrist-worn neuromodulation ("wrist device"), treatment with an ear-worn neuromodulation device ("ear device") and sham stimulation with wrist-worn device that does not actually deliver stimulation ("sham device"). ECG patches will be worn on the chest to measure AF episode onset and duration ("ECG Patch"). Additionally, a wrist-worn monitoring device will be used for the measurement of heart rate (HR), heart rate variability (HRV), and other biomarkers ("Cardiac Measurement Device (CMD)"). Finally, subjects will track AF episode onset, duration, and symptom type in an AF diary.
The study is a prospective, randomized, single-blind clinical trial aiming to compare two method in guidance of Vein of Marshall ethanol infusion (VOMEI), i.e., the conventional fluoroscopy-guided VOMEI and UNIVU-guided VOMEI.
In this study, the investigators evaluated the association between various measures of adiposity [BMI and waist circumference (WC)] and clinical outcomes in Asian patients with AF who were prescribed OAC, using a nationwide population based cohort.
