Filter by: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 patients, obviating active cardioversion. Recurrences within one month were seen in 30% of patients in both groups, i.e. the initially chosen strategy did not affect the recurrence pattern. Considering the latter, it remains unclear whether cardioversion is needed at all, especially since cardioversion strategy does not seem to affect behaviour of the arrhythmia over time. Instead of cardioversion a watchful-waiting rate control strategy may be appropriate as initial strategy. This allows observing the electrical and clinical behavior of arrhythmia, providing a solid basis for comprehensive and effective early rhythm control. This study is a multi-center clinical randomized controlled trial to show non-inferiority of watchful-waiting with rate control versus routine care in terms of prevalence of sinus rhythm at 4 weeks follow-up, using a novel telemonitoring infrastructure to guide rate control during follow-up.
This is a prospective, adaptive, multi-center, randomized safety and effectiveness pivotal study comparing the FARAPULSE Pulsed Field Ablation System with standard of care ablation with force-sensing RF catheters and cryoballoon catheters indicated for the treatment of PAF.
The aim of the study is to evaluate the effect of a person-centred nurse-led outpatient clinic on health related quality of life, for persons with AF. Secondary outcomes are effects on anxiety, depression, illness perception, symtom burden, life style and health economics.
First-in-Patient Study for sing le dose of M201-A hydrochloride injection in Japanese patients with paroxysmal atrial fibrillation.
Postoperative atrial fibrillation (POAF) is a common complication that occurs in 30-50% of patients after cardiac surgery and increases morbidity and mortality and hospital length of stay. During the perioperative period, the discontinuation of beta-blocker treatment is known to be a risk factor for developing POAF in patient undergoing cardiac surgery. Early beta-blocker reintroduction is associated with lower incidence of POAF. Unfortunately, side effects of currently available beta-blockers (including esmolol), such as low blood pressure and excessive bradycardia and/or their extended duration of action, limit their use in the post-operative period especially for prevention. Landiolol, an ultra-short acting injectable beta-blocker, offers the advantage of significantly limiting low blood pressure events while increasing therapeutic efficacy in the treatment of POAF in cardiac and non-cardiac surgery. Landiolol, when used at low dose in the postoperative period, has been showed to reduce the incidence of POAF with no increased incidence of side effect as compared to standard of care. The limitation is that these promising data come from single center studies with limited samples and conducted exclusively in Japanese population. If landiolol is approved for use in the treatment of atrial fibrillation in non-Asian patients, there are no data on the prevention of POAF in cardiac surgery. The objective of this multicenter, double-blind, randomized, placebo- controlled phase III trial is to confirm that landiolol postoperative infusion is associated with lower incidence of POAF without excess of adverse events as compared to standard of care in a non-Asian population after cardiac surgery with sternotomy.
The present prospective cohort study (not randomized) analyses the value of screening and treatment of SAHS in the management of patients with AF refractory to antiarrhythmics drugs, potentially candidates for ablation. Patients at low risk of suffering from SAHS will follow conventional management of their AF, according to the usual criteria of the Arrhythmia Unit. Patients with high or intermediate risk of SAHS, will undergo respiratory polygraphy. If the result is positive, they will be treated as standard for this syndrome and their heart rate will be monitored for 3 months. After this, the patient's arrhythmic load will be reevaluated differentiating patients into two groups, those that must be ablated from those that have improved their condition and the clinical criteria is no longer ablation but follow-up.
Redo procedures after CLOSE-guided pulmonary vein isolation (PVI) for atrial fibrillation (AF) occur in 10% of patients. In case of pulmonary vein (PV) reconnection, electrophysiologists may re-isolate the pulmonary veins with or without the ablation of other commonly known PV-triggers. The superior vena cava (SVC) is one of the most common non PV-triggers for atrial tachyarrhythmias. SVC electrical isolation can be reached by circular radiofrequency-ablation under close monitoring of the phrenic nerve. However, it's added value remains unclear. With this prospective, randomized, controlled, unblinded, mono-center study, the investigators aim to evaluate the 1-year recurrence rate in paroxysmal AF patients with reconnected pulmonary veins during a redo ablation with PV re-isolation or PV re-isolation with SVC isolation.
Paroxysmal atrial fibrillation (AF) induce, in the affected patient, a prominent negative effect on health-related quality of life (HR-QoL) and physical fitness. The health care utilisation is high and the patient does never know when the next attack of atrial fibrillation occurs. Therefore, is physical exertion often avoided due to fear of new attacks. Further, are shortness of breath and fatigue often present despite of prescribed modern drugs. Paroxysmal AF per se enhance markedly the risk to develop stroke and heart failure, which both are syndromes that cause further negative effect on the patient´s HR-QoL and physical fitness. Altogether, cause the symptoms in paroxysmal AF a vicious spiral where both VO2max and muscle function deteriorate. The problems with shortness of breath might be due to dysfunction in respiratory muscles. Physiotherapy led exercise within cardiac rehabilitation (PT-X) in combination with inspiratory muscle training (IMT) has shown positive effects in patients with permanent atrial fibrillation. However, to our knowledge, not yet investigated in patients with paroxysmal AF. Aim: Primary to investigate, in a multicentre randomised controlled trial, if PT-X in combination with IMT can impact HR-QoL in patients with paroxysmal AF. Secondary to investigate the effect of PT-X in combination with IMT regarding symptoms, physical fitness, physical activity and the number of atrial fibrillation attacks and health care costs compared to the control group, asked to live their usual life, during the study period. Expected outcome: PTX in combination with IMT can improve HR-QoL, respiratory muscle function, level of symptoms, physical fitness and physical activity in patients with paroxysmal AF. In addition, a reduced number of atrial fibrillation attacks could decrease the direct cost of health care.
The aim of the present study is to compare the LA reconstruction obtained with CartoSound-FAM software and The M-FAM software to the Carto Merge 3D reconstruction and FAM in consecutive patients referred for AF ablation.
Patients will atrial fibrillation, a type of irregular heart rhythm, frequently go to the emergency room in order to manage their condition. This study will use a chart review to look at the characteristics and frequency of atrial fibrillation patients who go to the emergency room. In addition to the chart review, patients with atrial fibrillation who have recently gone to the emergency room or have been hospitalized will be approached and asked if they want to use an electronic health care system that can be accessed by both themselves and their health care providers. Along with the system, patients will be given a Health Canada approved heart rhythm sensor, so patients will be able to record their heart rhythm when they feel symptoms and send the information to the heart rhythm team. The heart rhythm team will then make real-time recommendations to the patient about how they can manage their rhythm and symptoms. Patients will be asked to complete satisfaction and quality of life surveys. Our goal is to provide efficient and effective care for patients with AF, resulting in decreased repeat ED visits.
