1. Classfications of catheter ablation.
| Type of AF | Basal technics | Skills | Combined Skills |
| Paroxysmal | PVI: targeted at ablation of the muscular sleeves | Ostial PVI | |
| Circular ostials PVI | |||
| Segmental PVI | |||
| PV ablation (Circumferential PV ablation, CPVA) | |||
| Circumferential PV isolation (CPVI) | |||
| Ablation of complex fractionated atrial electrograms (CFAE) | |||
| Ablation of autonomic plexuses | |||
| Combined approaches | PVI plus ablation of vein of Marshall | ||
| PVI plus ablation of superior vena cava | |||
| Inducibility guided additional ablation targeting the substrate | |||
| Adding Mitral isthmus line | |||
| Adding roofline | |||
| PVI plus CFAE | |||
| Combinations of more than 2 techniques | |||
| Double/single Lasso technique | |||
| PV antrum isolation | PV antrum isolation guided by ICE | ||
| Wide anatomic circumferential ablation: encircling the PVs within the left atrium | |||
| Persistent | PVI alone | ||
| Linear lesions | Mitral isthmus ablation | ||
| Roofline ablation | |||
| Ablation of anterior left atrial line | |||
| Combined approaches | PVI plus Mitral ablation | ||
| PVI plus roofline ablation | |||
| PVI plus ablation of anterior left atrial line | |||
| Stepwise ablation techniques | Ablation of focal source in addition to PV foci | ||
| Double atrium ablation |
PV: Pulmonary vein; PVI: pulmonary vein isolation; ICE: Intracardiac Echocardiography.
