Innovations in radiofrequency (RF) ablation and nonablative techniques have led to significant advances in addressing complex arrhythmogenic substrates for a variety of cardiac arrhythmias. Anatomical challenges, deep substrate, and mid‐myocardial locations may pose difficulties and decrease success rates using routine methods. In this review, we provide an update on novel RF technology and techniques including (a) high‐power, low‐duration ablation, (b) ablation facilitated by low‐ionic irrigant, and (c) bipolar ablation. In addition, we review emerging technologies including electroporation, needle catheter ablation, and ablation with the lattice catheter.
