In electrophysiology, innovation is king, but it is often incremental, and it almost always lacks rationale, comprehensive clinical documentation and relevance for hospitals that try to balance the increasing costs of new technology with increasing demand and reimbursement that just can’t keep pace. So, again, innovation is great.

Introduction Catheter ablation is an effective and safe strategy for treating atrial fibrillation patients. Nevertheless, studies on the long-term outcomes of catheter ablation in patients with dilated cardiomyopathy are limited. Among the catheter ablation group, 58.7% ( n  = 27) had persistent atrial fibrillation.
