Filter by:The goal of this clinical trial is to compare the rhythm control effect in hypertrophic non-obstructive patients with non-paroxysmal atrial fibrillation by either concomitant catheter endocardial and thoracoscopic epicardial ablation or catheter ablation alone. The study aims to see if concomitant hybrid ablation can more effectively achieve rhythm control effect than catheter ablation alone in non-paroxysmal atrial fibrillation patients with hypertrophic cardiomyopathy.
Atrial fibrillation (AF) is the most common arrhythmia among adults with increasing risk of stroke, heart failure and mortality. The EAST-AFNET 4 trial showed that rhythm control treatment (Antiarrhythmic drugs AAD or catheter ablation) was associated with a lower risk of adverse cardiovascular outcomes than usual care among patients who had recently (within one year) been diagnosed with atrial fibrillation. In phase II/III GLORIA AF registry, Early AF ablation within 3 months from initial diagnosis in a contemporary cohort of patients who were predominantly treated with non-vitamin K antagonist oral anticoagulants was associated with a survival advantage compared to medical therapy alone. Moreover, early AF ablation appeared to provide the greatest benefit compared to other treatments. The ATTEST trial was a multicenter, randomized, prospective study in patients with paroxysmal atrial fibrillation (AF) designed to assess whether radiofrequency (RF) ablation is more effective in delaying the progression to persistent AF than AADs. Patients >_65 years were significantly more likely to progress to persistent AF/AT than patients were <65 years, suggesting that early RF ablation may be an effective treatment strategy for delaying AF progression. So, we hypothesize that early AF ablation within one year after first AF diagnosis may associate with improved procedures outcomes in symptomatic AF patients.
The primary objective of the study aims to compare soluble CD154 (CD40L) levels before and after radiofrequency ablation (RFA) in patients with colorectal cancer (CRC) liver metastases. The secondary objectives aims: - to compare soluble CD154 (sCD40-L) levels before and after treatment by RFA or surgery alone in patients with CRC liver metastases; - to study the feasibility and reliability of soluble CD154 (sCD40-L) levels to detect and quantify the induction of immun response in CRC liver metastases patients after RFA; - to study the impact of surgery on plasma soluble CD154 levels; - to study association between CD154 expression level before and after RFA in CRC liver metastases patients and relapses rate at 1 year.
