Filter by:The single procedure success rates of durable pulmonary vein isolation (PVI) for paroxysmal atrial fibrillation (PAF) varies between 80 and 90 %. This prospective, randomized study investigated the efficacy of pulmonary vein isolation with RF-energy following the CLOSE protocol with standard energy application (30 Watts) versus PVI with RF-energy with high power settings (45 Watts).
An observational, prospective, cohort study aiming to assess the potential predictive role of cardiopulmonary exercise testing in the prognosis of paroxysmal atrial fibrillation, in combination with echocardiographic indices and plasma biomarker values.
The purpose of this study is to provide real-world data useful to address the factors associated to the administration of oral anticoagulants in the elderly population affected by non-valvular atrial fibrillation (NVAF), in Italy, and it's persistence rate after one year.
The DIAMOND AF Post Approval study is a prospective, global, multi-center, non-randomized, single-arm observational trial
Atrial fibrillation (AF) is a heart problem that causes an irregular heartbeat. It can cause the heart to beat more rapidly and reduce the heart's ability to pump blood around the body efficiently, causing heart failure. It also increases the risk of blood clots forming inside the heart. These clots may then be pumped out of the heart, through the blood vessels, to other parts of the body. This can cause strokes if the clots spread to the brain. AF is a common problem outside an Intensive Care Unit (ICU), where treatment is based on good, evidence-based guidelines designed to reduce the risk of problems like heart failure or strokes. Around 10% of patients treated in ICU develop atrial fibrillation as a complication of their underlying illness. Some patients will recover their normal heart rhythm before leaving the ICU, often with the help of some medical treatments. It is not known whether these patients will get AF again after leaving the ICU, or when this is likely to happen. It is also unknown whether patients who avoid AF whilst on the ICU may still be at high risk of developing it after they leave. This study will identify patients on the ICU who have no previous record of atrial fibrillation. These patients will be monitored whilst on the ICU to identify those who develop AF. Those patients who develop new onset AF will be monitored on the ward after leaving the ICU to see which patients have AF at this point. The heart monitoring will be repeated once the patients leave hospital, again to identify whether they have atrial fibrillation. Some studies suggest that AF during critical illness causes a long-term risk of recurrent AF and AF associated complications such as heart failure, stroke, and death. To understand how to minimise these risks in intensive care patients, we need to know how which patients who develop atrial fibrillation whilst in an ICU go on to have recurrent atrial fibrillation in hospital and in the community. These patients may benefit from interventions to reduce long term adverse events such as anticoagulation to reduce stroke risk.
The STOP AF First PAS is a prospective, global, multi-center, observational trial.
The purpose of this study is to evaluate the safety and effectiveness of the Laminar Left Atrial Appendage Closure System to treat patients with non-valvular atrial fibrillation that cannot take, or a have a reason to seek an alternative, to anticoagulant medications.
Atrial Fibrillation (AF) is the most common abnormal heart rhythm(arrhythmia) affecting about one in 40 people in England. Patients with AF often have symptoms ranging from palpitations and breathlessness, and a small number of patients may develop heart failure. The major complication of AF is stroke, and this is effectively treated with blood thinning medications (anticoagulation). AF symptoms can lead to significant decline in quality of life and can affect patients' ability to work and exercise. There are numerous treatments targeted at maintaining normal rhythm and preventing AF recurrence. These include medications and catheter ablation. Ablation has been shown to be more effective than medications for the long-term control of AF, but its efficacy is significantly reduced by upstream conditions such as high blood pressure, obesity, diabetes, and poor fitness levels. This results in increased complications, repeat procedures, and increased AF recurrence or patients. Research currently available has shown that intensive risk factor control with weight loss and increased fitness can reduce AF burden and improve results from ablation. However, achieving these targets outside of a clinical trial have been challenging. Recent data has shown that a new class of drug (Liraglutide) can result in significant weight loss over a 3-month period, and pre-treatment prior to liver transplant has improved results and patient recovery. The overall aim of this study is to determine if accelerated weight loss by Liraglutide before AF ablation is feasible to base a future trial to inform if this approach improves outcomes and can be safely adopted into routine clinical practice.
The trial is a prospective, non-randomized, single-arm feasibility trial to evaluate physician acceptance of the NeuTrace System v1.0 for cardiac electroanatomic mapping.
This study will compare right sided atrioventricular node ablation to left sided atrioventricular node ablation
