Filter by:Cryoballoon ablation is proven to be effective in pulmonary vein isolation in patients with paroxysmal atrial fibrillation, and it can reduce the procedure time compared to conventional radiofrequency (RF) catheter ablation. Recently, high-power short-duration RF ablation has been known to reduce procedure time remarkably, and it can eliminate extra-pulmonary vein foci, which cannot be treated by Cryoballoon ablation. The aim of this study is to compare Cryoballoon ablation and high-power short-duration RF ablation in patients with paroxysmal atrial fibrillation in terms of the efficacy and the safety in a prospective randomized trial.
This study intends to explore a new therapy to reduce the incidence of atrial fibrillation in thoracic patient who receive video-assisted thoracoscopic lobectomy .The results of the study are to assess the effects of this new intervention on the incidenceļ¼duration of atrial fibrillation and other complications including postoperative delirium after video-assisted thoracoscopic lobectomy .And reducing the burden of POAF on patients and their families, hospitals and public resources.
New parameters or methods, such as ablation index, have been developed for the quantification of high-frequency energy used in pulmonary vein isolation, but there is no known method for atrial fibrillation considering individual differences in atrial tissue. The atrium is only 1/3 of the thickness of the ventricle and is thinner in women and older than men or young people. The aim of this study was to evaluate the efficacy and safety of radiofrequency energy therapy using atrial individual differences. In order to reflect the thickness of the atrium, we will use the unipolar and bipolar maps and the myocardial thickness map using computed tomography (CT) images. To evaluate the efficacy and safety of energy titration therapy by random assignment of high frequency energy therapy group, CT image application high frequency energy therapy group, and existing empirical high frequency therapy group.
The aim of this study is to evaluate the effectiveness of a 16 week mindfulness-based coaching program compared to a cardiovascular risk reduction education program. Both groups will undergo 24-hour ambulatory blood pressure monitoring, along with assessments of psychological measures (see bellow) at study baseline, midpoint (8 weeks), and conclusion (16 weeks). In addition, both groups will also undergo 24-hour Holter monitoring assessments at study beginning and conclusion to assess possible episodes of atrial tachyarrhythmia during the assessed interval.
Primary Aim: To determine if apixaban is superior to aspirin for prevention of the composite outcome of any stroke (hemorrhagic or ischemic) or death from any cause in patients with recent ICH and atrial fibrillation (AF). Secondary Aim: To determine if apixaban, compared with aspirin, results in better functional outcomes as measured by the modified Rankin Scale.
Atrial fibrillation in the postoperative period of myocardial revascularization surgery (AF-POMR) occurs in 10% to 65% of patients, increasing morbidity and mortality after surgery. is associated with an increase in hospital length of stay, and, thus, in costs,and can cause serious clinical complications, such as hypotension, heart failure, stroke and other thromboembolic disorders.Although not completely understood, the electrophysiological mechanism of AF-POMR is believed to be reentry.
Obesity paradox In patient with non valvular atrial fibrillation
The proposed study will investigate the clinical use of the ISCDX test that may differentiate between diverse stroke etiologies as listed below: Aim 1: Differentiate between cardioembolic and large artery atherosclerotic ischemic strokes, when hemorrhagic stroke is ruled out, as defined by TOAST classification of subtypes of acute ischemic stroke. Aim 2: In cases of ischemic strokes of unknown or "cryptogenic" etiology, determine the ability of biomarker blood tests to predict etiology between cardioembolic and large artery atherosclerotic.
Patients undergoing first time cardiac surgery will undergo rapid atrial pacing prior to initiation of cardiopulmonary bypass to screen for AF inducibility. Patients with inducible AF will be randomized to prophylactic amiodarone treatment versus no treatment. Patients who are not inducible to AF will be treated with standard post-operative care. Patients will be monitored post-operatively to explore the value of intraoperative inducibility of AF to predict POAF and to evaluate whether the combination of intraoperative inducibility and precision amiodarone therapy is effective at reducing the incidence of POAF
The study aims to evaluate the appropriateness of initiating oral anticoagulation for stroke risk reduction in dialysis populations with atrial fibrillation. Specifically, the study will assess the overall safety, tolerability, and efficacy of initiating treatment with Warfarin in patients with end-stage renal disease on dialysis and atrial fibrillation.
