Depolarization and Repolarization Parameters on ECG Predict Recurrence after Atrial Fibrillation Ablation in Patients with Hypertrophic Cardiomyopathy
ConclusionsIn patients with HCM undergoing AF ablation, QTc prolongation, specifically>448 ms, and presence of fQRS are independent risk factors for arrhythmia recurrence at follow ‐up. The combination of these two parameters has greater predictive value and would help to identify patients who are at the highest risk of procedural failure.This article is protected by copyright.

Unusual variants of pre ‐excitation: From anatomy to ablation: Part I—Understanding the anatomy of the variants of ventricular pre‐excitation
AbstractThe famous quotation of Winston Churchill, made in his radio broadcast of 1939 regarding Russia's next move, specifically “A riddle wrapped up in a mystery, inside an enigma, ” perfectly fits the current understanding of unusual accessory atrioventricular pathways, including the variants producing ventricular pre‐excitation. It was many decades after their original descriptions that we came better to begin to understand most of their structure‐function relationship s. Their mysterious pathophysiology was sometimes unveiled after invasive treatments, such as surgical ablation of the atrioventricular ...

Determination of single cryoablation outcome within 30 to 60  seconds of freezing based on ice impedance
ConclusionThe efficacy of single cryoablation can be defined within 30 to 60  sec based on ice impedance. Three unique impedance profiles described in this investigation are associated with the uniformity and thickness of the ice buildup on the anterior surface of the balloon. One cryoablation with an adequate impedance rise is needed for successful outcomes. (Source: Journal of Cardiovascular Electrophysiology)

Experimental verification of the value of the Tpeak –Tend interval in ventricular arrhythmia inducibility in an early repolarization syndrome model
AbstractIntroductionIn patients with early repolarization patterns on ECG, many researchers have studied to find predictors of fatal arrhythmia. However, there are no satisfying clinical predictors. We evaluated the value of the Tpeak–Tend interval on pseudo ‐ECG in canine myocardial wedge preparation models of early repolarization syndrome.Methods and ResultsTransmural pseudo ‐ECG and endocardial/epicardial action potentials were recorded from coronary‐perfused canine left ventricular wedge preparations (n = 34).

From near ‐zero to zero fluoroscopy catheter ablation procedures
AbstractAimsThe use of electroanatomical mapping systems (EAM) can reduce radiation exposure (RX) and it can also completely eliminate the use of RX. Radiation exposure related to conventional radiofrequency (RF) ablation procedures can have a stochastic and deterministic effect on health. The main aim of this study was to evaluate the safety and feasibility of an entirely non ‐fluoroscopic approach to catheter ablation (CA) using EAM CARTO3.MethodsIn 2011 we started a RX ‐minimisation programme in all procedures using the CARTO system with the deliberate intention to not resort to the aid of RX unless strictly necessa...
