Since the 1980s, dramatic advances in electrophysiology procedures have occurred. Catheter positioning is most often assisted by fluoroscopy. Sophisticated electroanatomical mapping systems can also display catheter position and create a 3D depiction of the anatomy. Magnetic resonance imaging (MRI) and computed tomography (CT) data can also be integrated, facilitating complex ablation procedures. Ablation is most commonly achieved with application of radiofrequency (RF) energy. Freezing with
