Catheter Ablation of Refractory Ventricular Fibrillation Storm After Myocardial Infarction.

Background: Ventricular fibrillation (VF) storm after myocardial infarction (MI) is a life-threatening condition that necessitates multiple defibrillations. Catheter ablation is a potentially effective treatment strategy for VF storm refractory to optimal medical treatment. However, its impact on patient survival has not been verified in a large population.

Management of asymptomatic arrhythmias: a European Heart Rhythm Association (EHRA) consensus document, endorsed by the Heart Failure Association (HFA), Heart Rhythm Society (HRS), Asia Pacific Heart Rhythm Society (APHRS), Cardiac Arrhythmia Society of Southern Africa (CASSA), and Latin America Heart Rhythm Society (LAHRS).

Asymptomatic arrhythmias are frequently encountered in clinical practice. Although studies specifically dedicated to these asymptomatic arrhythmias are lacking, many arrhythmias still require proper diagnostic and prognostic evaluation and treatment to avoid severe consequences, such as stroke or systemic emboli, heart failure, or sudden cardiac death. The present document reviews the evidence, where available, and attempts to reach a consensus, where evidence is insufficient or conflicting.

Acute safety, effectiveness, and real-world clinical usage of ultra-high density mapping for ablation of cardiac arrhythmias: results of the TRUE HD study.

Aims: The objective of this study was to verify acute safety, performance, and usage of a novel ultra-high density mapping system in patients undergoing ablation procedure in a real-world clinical setting.

Methods And Results: The TRUE HD study enrolled patients undergoing catheter ablation with mapping for all arrhythmias (excluding de novo atrial fibrillation) who were followed for 1 month. Safety was determined by collecting all serious adverse events and adverse events associated with the study devices.

Is mean heart dose a relevant surrogate parameter of left ventricle and coronary arteries exposure during breast cancer radiotherapy: a dosimetric evaluation based on individually-determined radiation dose (BACCARAT study).

Background: Intra-individual heterogeneity of cardiac exposure is an issue in breast cancer (BC) radiotherapy that was poorly considered in previous cardiotoxicity studies mainly based on mean heart dose (MHD). This dosimetric study analyzes the distribution of individually-determined radiation doses to the heart and its substructures including coronary arteries and evaluate whether MHD is a relevant surrogate parameter of dose for these substructures.

Methods: Data were collected from the BACCARAT prospective study that included left or right unilateral BC patients treated with 3D-Conformal Radiotherapy (RT) between 2015 and 2017 and followed-up for 2 years with repeated cardiac imaging examinations.

Cost-effectiveness of trans-nasal endoscopic sphenopalatine artery ligation vs arterial embolisation for intractable epistaxis: Long-term analyses.

Objectives: Trans-nasal endoscopic sphenopalatine artery ligation (TESPAL) and endovascular arterial embolisation both provide excellent success rates for intractable epistaxis. Recent economic models suggest that TESPAL could be a cost-saving strategy. Our main aim was to perform cost-effectiveness analyses on TESPAL compared with embolisation to treat patients with epistaxis.

Methods: Invasive arterial pressure measurements from 17 patients with PVC-CM and 16 controls with frequent PVCs were retrospectively analyzed.

Comparison between novel and standard high-density 3D electro-anatomical mapping systems for ablation of atrial tachycardia.

Ultra-high-density mapping allows very accurate characterization of circuits/mechanisms in atrial tachycardia (AT). Whether these advantages will translate into a better procedural or long-term clinical outcome is unknown. Sixty consecutive AT ablation procedures using ultra-high-density mapping (Rhythmia™, group 1) were retrospectively compared to 60 consecutive procedures using standard high-density mapping (Carto/NavX™, group 2) (total 209 AT, 79% left AT).

Epicardial Ventricular Tachycardia Ablation Guided by a Novel High-Resolution Contact Mapping System: A Multicenter Study.

Background Mapping using a multipolar catheter with small and closely spaced electrodes has been shown to improve the validity of electrograms to identify endocardial critical sites of reentry isthmus and foci of earliest activation. However, the feasibility, safety, and clinical outcome of using such technology to guide epicardial ventricular tachycardia (VT) ablation has not been reported. Methods and Results Thirty-three consecutive patients from 5 high-volume centers were studied.

An African loss-of-function CACNA1C variant p.T1787M associated with a risk of ventricular fibrillation.

Calcium regulation plays a central role in cardiac function. Several variants in the calcium channel Ca1.2 have been implicated in arrhythmic syndromes.

Position paper concerning the competence, performance and environment required in the practice of complex ablation procedures.

The introduction of catheter ablation techniques has vastly improved the treatment of cardiac arrhythmias. However, as complex ablations are technically demanding and can cause various complications, they require a high level of expertise to maximize success rates and minimize complication rates. As French recommendations regarding the required technical competence and equipment are not yet available, this position paper has been compiled by the Working Group of Pacing and Electrophysiology of the French Society of Cardiology, detailing the required features of an interventional cardiac electrophysiological centre for complex ablation procedures: (1) sufficient institutional volume; (2) physician training, qualifications and experience; (3) paramedical staff training and attendance; and (4) institutional facilities and technical equipment.

Oncologic outcomes with transoral robotic surgery for supraglottic squamous cell carcinoma: Results of the French Robotic Surgery Group of GETTEC.

Crossroads or "Flyovers" novel insights into ventricular tachycardia mechanisms: The path is twisting.

Diverging channels of activation may be observed in some ventricular tachycardia (VT) using ultra-high-density mapping. We present here cases of such diverging activation patterns as observed from 60 consecutive VT activation maps using the Rhythmia system™ (Boston Scientific, Marlborough, MA, USA). Diverging directions of activation in the same area with "crossroads" or "flyover" pattern can be traced, implying recording of independent multilayer channels.

Three-dimensional mapping in the electrophysiological laboratory.

Investigation and catheter ablation of cardiac arrhythmias are currently still based on optimal knowledge of arrhythmia mechanisms in relation to the cardiac anatomy involved, in order to target their crucial components. Currently, most complex arrhythmias are investigated using three-dimensional electroanatomical navigation systems, because these are felt to optimally integrate both the anatomical and electrophysiological features of a given arrhythmia in a given patient. In this article, we review the technical background of available three-dimensional electroanatomical navigation systems, and their potential use in complex ablations.

Surgical antegrade transcatheter valve implantation and heavily calcified heart.

It is well known that a heavily calcified mitral valve significantly increases the perioperative and postoperative risks of mitral valve surgery.
