Trends in ablation procedures in Greece over the 2008-2018 period: Results from the Hellenic Cardiology Society Ablation Registry.

Objective: In 2008, the radiofrequency ablation (RFA) procedures registry of the Hellenic Society of Cardiology was created. This online database allowed electrophysiologists around the country to input data for all performed ablation procedures. The aim of this study is to provide a thorough report and interpretation of the data submitted to the registry between 2008 and 2018.

Radiofrequency ablation procedures in Greece: initial experience and results from the national registry 2008-2010.

Introduction: In 2008 the radiofrequency ablation procedures (RFA) registry of the Hellenic Cardiological Society (HCS) was created. This is a dynamic, web-based application, which acts as the interface for storing and retrieving patients' demographic data and ablation procedures. Access to the site is permitted only to registered users.

Atrioventricular node modification in patients with chronic atrial fibrillation: role of morphology of RR interval variation.

Background: This study evaluates the role of RR interval distribution pattern as an outcome predictor of radiofrequency (RF) modification of atrioventricular (AV) node in chronic atrial fibrillation (AF) and attempts to elucidate the likely mechanism of rate control.

Methods And Results: Sixty-five patients with chronic AF underwent AV node modification. The RR interval distribution pattern was derived from 24-hour ECG recordings obtained before and after the procedure.

A noninvasive method for the detection of dual atrioventricular node physiology in chronic atrial fibrillation.

Considering the electrophysiologic study as a reference, the RR interval distribution analysis is a sensitive (88%) and specific (80%) noninvasive method for detecting dual atrioventricular (AV) node physiology. This method may prove useful in selecting patients with atrial fibrillation who are considered appropriate candidates for radiofrequency modification of AV nodal conduction as opposed to AV nodal ablation.

Chronic atrial fibrillation and incessant ventricular tachycardia treated with a single transcatheter ablation.

We present a unique patient with a 12-year history of chronic atrial fibrillation resistant to external direct current shocks associated with incessant ventricular tachycardia. Both arrhythmias were treated with a single shock delivered through a catheter at the atrioventricular junction. The other unusual feature is that sinus rhythm has been maintained in a follow-up of 6 months after the intervention.
