The present report describes the program of radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF) in patients referred to the AF Clinic of the National Institute of Cardiology. Specific inclusion criteria are required for RFCA of AF. If the patient fulfills it, then an electrophysiological study is performed. A transseptal approach and special mapping catheters are used to detect abnormal electrical activity (AEA). Pulmonary vein isolation is performed at the ostium/ antrum of those veins with AEA if the patient had paroxysmal AF. Global pulmonary vein isolation with some additional lines guided by electroanatomical mapping is performed in the case of chronic AF. Postoperative follow-up includes consultation, ECG and Holter monitoring at 1, 3, 6 and 12-month. RFCA is a useful and relatively safe procedure for the treatment of AF and the only one with curative potential.

Background: Recent advancements in ultra-high-density mapping (UHDM) featuring automated functionalities have enhanced our understanding of micro-reentrant atrial tachycardias (mAT) circuits and the precise localization of the origin.
Purpose: To evaluate the diagnostic support provided by an automated UHDM algorithm in guiding the ablation of mATs.
Methods: Consecutive patients eligible for AT ablation in 22 Italian centers were prospectively enrolled.

Background: Discrete prepotentials (DPPs) mapped inside aortic sinuses of Valsalva (ASVs) are deemed as reliable targets for ablation of premature ventricular contractions (PVCs). Nevertheless, ablation may still fail, necessitating further investigation. This study aimed to investigate the electrophysiological features and ablation approaches for PVCs with failed ablation inside ASVs, despite identified DPPs.

Ventricular tachycardia (VT) is a life-threatening arrhythmia often leading to sudden cardiac death, particularly in critically ill patients. Refractory VT, characterized by recurrent episodes requiring intervention, poses unique challenges for management, necessitating advanced diagnostic and therapeutic strategies. This systematic review evaluates the impact of imaging and pharmacological treatments in managing refractory VT in critically ill patients.

The postacute myocardial infarction electrical storm is a life-threatening entity. Resistance to ischemia in Purkinje fibers may be the origin of short-coupled premature ventricular contractions that trigger severe arrhythmic events. We present a case where the use of emergency catheter ablation, guided by a 3D navigation system and an ultra-high-density mapping catheter, successfully terminated the arrhythmic storm.
