BACKGROUND: Electrophysiology procedures require fluoroscopic guidance, with the associated potentially adverse effects of ionising radiation. Newer fluoroscopy systems have more features that enable dose-reduction strategies. This study aimed to investigate any reduction in radiation dose between an older fluoroscopy system (Philips Integris H5000) and one of the latest systems (Siemens Artis Q), optimised with dose-reduction strategies. METHODS: Radiation dose measures were collected over a two year period in a single electrophysiology laboratory...

Victor Waldmann, Eloi Marijon, Nicolas Combes
We present a case of sudden cardiac arrest seven hours after radiofrequency ablation of the atrioventricular junction for symptomatic permanent atrial fibrillation unresponsive to medical therapy. The Holter monitoring revealed a progressive increasing of QT interval after the procedure, highlighting the repolarization instability after acute changes in heart rates associated with modification of ventricular activation, leading to occurrence of short coupling interval ventricular extra beats and finally to a "Torsade de Pointes"...

All contemporary pacemakers undergo automatic reprogramming upon reaching elective replacement indication due to battery depletion. The majority of such reprogramming will result in changes to both pacing mode and pacing rate. The exact software reprogramming varies considerably among pacemaker manufacturers and may even vary amongst models of the same manufacturer. Accordingly, it is essential for health care providers managing pacemaker patients to have a detailed understanding of the automatic reprogramming seen at elective replacement indication as well as their potential physiological and clinical consequences...

BACKGROUND: Studies have shown that remote monitoring (RPM) of implantable cardioverter defibrillators (ICDs) is at least comparable to in-clinic follow-up with regard to clinical outcomes and might be cost-effective, yet RPM is not standard clinical practice within Europe. Better insight into the patient perspective on RPM may aid in its acceptance, implementation and reimbursement. This narrative review 1) summarizes existing evidence on the impact of RPM on patient reported outcomes and 2) discusses future directions in examining the patient perspective...

BACKGROUND: Right atrial tachycardia (AT) is common arrhythmia post-surgical valve replacement in patients with rheumatic heart disease (RHD). However, the substrate and the mechanism of left AT in such patients and the ablation efficacy is less known. METHODS AND RESULTS: Twenty-seven RHD patients with AT were enrolled in this study, nine of them (33%) had Left AT. Five and four patients had left AT during the first and second procedure, respectively. A spontaneous scar in the left posterior wall was identified in all patients, and obvious anterior scar in three patients...

BACKGROUND: To broaden the utility of heart rate variability (HRV) in clinical medicine and mass screening, results based on shorter electrocardiogram (ECG) recordings require validation with those based on standard five-minute recordings. We investigated the association between HRV variables obtained from five-minute ECGs with those obtained from ECGs shorter than five minutes. METHODS: Twenty-two participants aged 20 to 69 years underwent five-minute resting ECG recordings in the supine position with natural breathing...

BACKGROUND: Ablation of drivers maintaining Atrial Fibrillation (AF) has been demonstrated as an effective therapy. Drivers in the form of rapidly-activated atrial regions can be non-invasively localized to either left or right atria (LA, RA) with Body Surface Potential Mapping (BSPM) systems. This study quantifies the accuracy of Dominant Frequency (DF) measurements from reduced-leads BSPM systems and assesses the minimal configuration required for ablation guidance. METHODS: Nine uniformly distributed lead sets of 8 to 66 electrodes were evaluated...

REVIEW
Chunmiao Wang, Yawen Zhang, Fangde Hong, Ying Huang
In patients without associated myocardial diseases, characterized by left bundle branch block (LBBB) and inferior axis morphologies, repetitive idiopathic right ventricular tachycardias (VTs) and ventricular premature contractions (VPCs) typically arise from right ventricular outflow tract (RVOT). Accumulated evidences have shown that radiofrequency catheter ablation (RFCA) is a useful treatment for patients with RVOT ventricular arrhythmias (VAs). Interestingly, several medical centers have showed that pulmonary artery (PA) is a potential novel site for catheter ablation in RVOT-like VAs, particularly in patients where termination of RVOT VAs at the usual site fails...

BACKGROUND: Permanent His bundle pacing (HBP) is a physiological alternative to right ventricular pacing (RVP). It is not known whether HBP can cause His-Purkinje conduction (HPC) disease. The aim of our study is to assess His bundle capture and its effect on LV function in long-term follow-up and to determine HPC at the time of pulse generator change (GC) in patients with chronic HBP. METHODS: HB electrograms were recorded from the pacing lead at implant and GC...

AIMS: The main aim of a study was to assess one-year mortality and its predictors in a cohort of patients who underwent transvenous lead extraction (TLE) procedure. METHODS: Retrospective analysis of clinical characteristics and 1-year follow up of patients referred for a TLE procedure in a single high volume center between June 2006 and October 2014 was performed. RESULTS: The studied population included 130 patients (82 males; mean age 64 ±15 years) implanted with pacemakers (74%), implantable cardioverter defibrillators (15%), or cardiac resynchronization therapy defibrillator (11%)...
