Contact-force local impedance algorithm to guide effective pulmonary vein isolation in AF patients: 1-year outcome from an international multicenter clinical setting
The combination of highly localized impedance (LI) and contact force (CF) may improve tissue characterization and lesion prediction during radiofrequency (RF) pulmonary vein isolation (PVI) in patients with at...

Timing of cryoballoon pulmonary vein isolation to prevent atrial fibrillation recurrence
The aims of this analysis were: to evaluate the impact of timing of ablation on the rate of atrial arrhythmias recurrence, verify if the timing of ablation impact differently in patients with paroxysmal and pe...

Role of CHA2DS2-VASc score in predicting atrial fibrillation recurrence in patients undergoing pulmonary vein isolation with cryoballoon ablation
Pulmonary vein isolation by cryoablation (PVI-C) is a standard therapy for the treatment of atrial fibrillation (AF). The CHA2DS2-VASc score is a well-established predictor of AF-related stroke. Whether the CHA2D...

Open AccessWhen local impedance meets contact force: preliminary experience from the CHARISMA registry
Highly localized impedance (LI) measurements during atrial fibrillation (AF) ablation have emerged as a viable real-time indicator of tissue characteristics and the consequent durability of the lesions created...

First clinical experience with the new four-pole standard connector for high-voltage ICD leads. Early results of a multicenter comparison with conventional implant outcomes
A new four-pole connector system (DF-4) for transvenous high-voltage implantable cardioverter defibrillators (ICD) is currently available in clinical practice. However, no clinical data demonstrating the safet...

Impact of pre-existent areas of complex fractionated atrial electrograms on outcome after pulmonary vein isolation
Atrial fibrillation (AF) drivers outside pulmonary veins (PV) may account for failure after PV isolation. The aim of this study was to characterize pre-existent areas of complex fractionated atrial electrogram...

Open AccessAssessment of the dynamics of atrial signals and local atrial period series during atrial fibrillation: effects of isoproterenol administration
The autonomic nervous system (ANS) plays an important role in the genesis and maintenance of atrial fibrillation (AF), but quantification of its electrophysiologic effects is extremely complex and difficult. A...

Role of the Autonomic Nervous System in Sustained Ventricular Tachycardia after Myocardial Infarction
The analysis of the autonomic control of the heart, by means of indirect markers, may represent a new approach for the identification of patients at high risk of sudden death after a myocardial infarction.
