简要总结

This study, called the PVI-AFL-HF Trial, investigates two treatments for patients with typical atrial flutter (AFL) and heart failure (HF). It aims to determine whether adding prophylactic pulmonary vein isolation (CPVI) to the standard cavo-tricuspid isthmus (CTI) ablation improves long-term outcomes compared to CTI ablation alone.
