Effect of Mechanical Ventilation on Radiofrequency Ablation in Atrial Fibrillation
Radiofrequency ablation (RFA) for atrial fibrillation (AF) is performed under general anesthesia. The success of the procedure depends on the safe contact of the catheter electrode with the myocardium. Movement of the catheter tip due to respiratory changes can result in inadequate lesion formation and AF recurrence. The success of …
Reversal of Atrial Substrate to Prevent Atrial Fibrillation Cohort Study
Atrial fibrillation (AF) is a major health problem, with a prevalence of 0.4-1% of the population. It results in high healthcare costs and significant morbidity, especially for patients with severe symptoms. The RASTA-AF randomized control trial (RCT) is designed to answer the following question: does vigorous treatment of AF with …
Study of Atrial Fibrillation Combined with Atrial Functional Mitral Regurgitation
To evaluate the improvement of mitral regurgitation after catheter ablation of atrial fibrillation or regular drug therapy in atrial fibrillation patients combined with atrial functional mitral regurgitation.
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. …
Implantable Cardiac Monitor to Detect Atrial Fibrillation in Patients With MINOCA
Myocardial infarction with non-obstructive coronary arteries (MINOCA) (i.e.<50% stenoses) on coronary angiography) is an underappreciated clinical entity concerning 5-6% of patients with acute myocardial infarction. Approximately 50% of these patients remain without appropriate diagnosis and treatment. The MINOCA study aims at systematically assessing the frequency of underlying pathologies of MINOCA …
Assessing the Burden of Perioperative Atrial Fibrillation in Patients Undergoing Cardiac Surgery
Background and Significance: In the United States approximately 220,000 patients undergo cardiac surgery per annum. Among potential complications, the incidence of atrial fibrillation (AF) is estimated at 30 - 60 %, and therefore presents the most common adverse event after cardiac surgery. Multiple complications may be associated with AF: Patients …
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 …
Mechanisms of Myocardial Injury and Ischemia in Patients With Rapid Atrial Fibrillation
The goal of this observational study is to better understand the role of measuring troponin (a protein measured by a blood test) and coronary imaging in patients presenting with rapid atrial fibrillation (AF) The main questions this study aims to answer are: Are patients with a fast, irregular heartbeat (rapid …
Quality of Life in Patients With Postoperative Atrial Fibrillation After Cardiac Surgery
Prospective observational study on quality of life with postoperative atrial fibrillation after cardiac surgery using SF-36 and qualitative questions
Prospective Database for Prediction of Atrial Fibrillation in Pacemaker and ICD Patients
Atrial fibrillation (AF) is associated with a five-fold increased risk of cerebrovascular stroke. While the risk of stroke in patients with known AF can be calculated via AF stroke prediction risk scores, the prediction of AF occurrence per se in individual patients remains difficult. We will recruit 250 patients with …
