Brief Summary:
This multicenter, randomized controlled trial aims to compare the clinical efficacy and safety of combining catheter ablation with Marshall vein ethanol ablation versus catheter ablation alone in patients with persistent atrial fibrillation (AF) and concomitant heart failure. Persistent AF is a common arrhythmia that significantly impacts the quality of life and survival rates, especially when coexisting with heart failure. While catheter ablation is a standard treatment for AF, its effectiveness in persistent AF, particularly in patients with heart failure, remains suboptimal. The addition of Marshall vein ethanol ablation may enhance treatment outcomes by targeting arrhythmogenic substrates. This study will enroll 120 participants across three centers to evaluate whether this combined approach can reduce AF recurrence, improve heart function, and enhance patient outcomes compared to catheter ablation alone.
Detailed Description:
Persistent atrial fibrillation (AF) combined with heart failure presents a significant clinical challenge due to the high rates of morbidity and mortality associated with these conditions. Catheter ablation is widely used to manage AF, but its efficacy in persistent AF, particularly in patients with heart failure, is limited. Recent advances suggest that targeting the Marshall vein with ethanol ablation may offer additional benefits by disrupting critical pathways involved in AF maintenance.
This study is designed to evaluate the efficacy of combining Marshall vein ethanol ablation with standard catheter ablation compared to catheter ablation alone in a well-defined patient population. Conducted across three centers, this randomized controlled trial will rigorously assess whether the combined approach can offer superior outcomes, including lower AF recurrence rates and improved heart function. The study's findings are expected to contribute valuable insights into optimizing treatment strategies for this high-risk patient group.
