Filter by:This study aimed to investigate safety and efficacy of intracardiac echocardiography (ICE)-guided zero-fluoroscopic cryoballoon ablation (CBA) in patients with paroxysmal atrial fibrillation.
Pulmonary vein isolation (PVI) is a cornerstone for catheter ablation of atrial fibrillation (AF), however, exact mechanisms of PVI efficacy remain debatable. It has been postulated that in patients with increased vagal tone AF can be treated by attenuation of parasympathetic drive to the heart using cardioneuroablation (CNA) by means of radiofrequency (RF) of the ganglionated plexi, however, data in literature and guidelines are lacking. The objective of this study is to examine the mid-term efficacy of RF-CNA targeting the right anterior ganglionated plexus (RAGP) in management of AF using right-atrial approach only.
Atrial fibrillation (AF) is one of the most common forms of heart rhythm disorder in patients with cardiovascular diseases. The choice of treatment for AF is a complex problem, depending on the form (paroxysmal, persistent, permanent) of AF, clinical manifestations of cardiac arrhythmias, associated diseases, the effectiveness of antiarrhythmic drugs. The accumulated data to date indicate an efficacy of the method of radiofrequency ablation (RFA) in the treatment of the paroxysmal form of AF. The RFA procedure does not eliminate the pathological processes that take place during developed AF. This dictates the need to develop and test new technologies and physical rehabilitation programmes for patients. The positive clinical effects of physical rehabilitation programmes based on moderate-intensity exercises are well known. The search for drugs capable of improving the results of RFA for AF in patients becomes urgent. This creates the prerequisites for the study of the clinical efficacy of trimetazidine MV in the rehabilitation of patients with cardiac diseases who underwent treatment of AF with RFA, which will optimize the management of such patients in the inpatient and outpatient setting.
This study is a prospective, randomized controlled study to compare overall clinical outcomes between High Power Short Duration (HPSD) and standard radiofrequency (RF) ablation settings for Atrial Fibrillation (AF) ablation in the treatment of subjects with paroxysmal or persistent Atrial Fibrillation.
It is a prospective, randomized and double-blind clinical trial involving an invasive technique for isolation of pulmonary veins (PVAC gold) in relation to clinical treatment during an one year of segment. The patients included have paroxysmal atrial fibrillation (aged 65 years and older) refractory to antiarrhythmic treatments that do not have structural and / or ischemic heart diseases. This trial employed quality of life scores prior to the study and during the sixth and twelfth month of the segment, electrocardiograms and holter of 24 hours. The proposed imaging tests was the transesophageal echocardiogram before each procedure. The cerebral MRI was performed in the 24 hours post invasive procedure and Angio-tomography of the pulmonary veins in the 6-month segment.
The I-STOP-Afib study will test the comparative effectiveness of using N-of-1 trials vs. symptom surveillance alone to reduce Atrial Fibrillation (AF) episode frequency and severity and improve quality of life for AF patients. The study will involve randomizing almost 500 paroxysmal AF patients to either AF episode tracking versus engaging in testing the relationship between participant-selected triggers and AF episodes utilizing a mobile-app based N-of-1 study design. Both groups will complete a validated survey to assess AF severity, essentially a measure of quality of life while living with AF, before and after a 3 month testing period.
