Abstract: Abstract Background The benefit–risk balance and optimal timing of surgery for severe infective endocarditis (IE) with ischemic or hemorrhagic strokes is unknown. The study aim was to compare the neurological outcome between patients receiving surgery or not. Methods In a prospective register-based multicenter ICU study, patients were included if they met the following criteria: (i) left-sided IE with an indication for heart surgery; (ii) with cerebral complications documented by cerebral imaging before cardiac surgery; (iii) with Sequential Organ Failure Assessment score ≥ 3. Exclusion criteria were isolated right-sided IE, in-hospital acquired IE and patients with cerebral complications only after cardiac surgery. In the primary analysis, the prognostic value of surgery in term of disability at 6 month was assessed by using a propensity score-adjusted logistic regression. Results 192 patients were included including ischemic stroke (74.5%) and hemorrhagic lesion (15.6%): 67 (35%) had medical treatment and 125 (65%) cardiac surgery. In the propensity score-adjusted logistic regression, a favorable 6-month neurological outcome was associated with surgery (odds ratio 13.8 (95% CI 6.2–33.7). The 1-year mortality was strongly reduced with surgery in the fixed-effect propensity-adjusted Cox model (hazard ratio 0.18; 95% CI 0.11–0.27; p

Abstract: Introduction and Objectives: Ablation of multifocal premature ventricular complexes (PVCs) is challenging. Activation mapping can be performed for the predominant morphology, but may be useless for other less prevalent ones. We aimed to describe the efficacy of an automated pace-mapping software-based ablation strategy for ablating the site of origin of multiple PVC locations. Methods: Consecutive patients referred for ablation of multifocal PVCs were prospectively enrolled. Spontaneous PVC templates were recorded and a detailed pace-mapping map was generated to spot the site of origin of PVCs. Results: A total of 47 PVCs were targeted in 21 patients (five and 16 patients with three or two PVCs morphologies each, respectively). Detailed pace-mapping comprising 73.5±41.6 different pacing locations was performed (best matching 97.2% [IQR 95.9-98.3%] similar to the clinical PVC). Activation points were acquired if possible, although ablation was only based on pace-mapping in 13 (27.6%) foci. Complete acute procedural success was obtained in 14 (66.7%) patients, while one PVC morphology was deliberately not ablated in five patients (23.8%). After 12.3±9.4 months of follow-up, PVC burden decreased from 24.4±10.4% to 5.6±5.0% (p

4. Atrioventricular nodal reentrant tachycardia ablation and inferior vena cava agenesis

Author: Vincent Galand, Dominique Pavin, Nathalie Behar, Philippe Mabo, and Raphaël P. Martins
Subjects: Diseases of the circulatory (Cardiovascular) system, RC666-701
Abstract: Congenital anomalies of the inferior vena cava (IVC) are rare and very often diagnosed in asymptomatic patients during computed tomography performed for other purposes. These anomalies can have significant clinical implications, for example if electrophysiology procedures are needed. Diagnostic and ablation procedures are difficult since catheter manipulation and positioning are more complex. We present here a case of successful atrioventricular nodal reentrant tachycardia ablation in a patient with unexpected IVC agenesis, using an azygos route. Resumo: As anomalias congénitas da veia cava inferior são raras e são, muitas vezes, diagnosticadas em pacientes assintomáticos como achados de tomografia computorizada realizada com outros objetivos. Estas anomalias podem ter implicações clínicas importantes, nomeadamente quando estão programados estudos eletrofisiológicos. Os procedimentos de diagnóstico e de ablação são difíceis, uma vez que o manuseamento e posicionamento do cateter é mais complexo. Apresentamos o caso bem-sucedido de uma ablação de taquicardia por reentrada nodal auriculoventricular num doente com agenesia da veia cava inferior, utilizando uma via trans-ázigos.

Abstract: Background: Recurrences of atrial fibrillation (AF) after pulmonary vein isolation (PVI) are mainly due to pulmonary vein reconnection. However, a growing number of patients have AF recurrences despite durable PVI. The optimal ablative strategy for these patients is unknown. We analyzed the impact of current ablation strategies in a large multicenter study. Methods: Patients undergoing a redo ablation for AF and presenting durable PVI were included. The freedom from atrial arrhythmia after pulmonary vein-based, linear-based, electrogram-based, and trigger-based ablation strategies were compared. Results: Between 2010 and 2020, 367 patients (67% men, 63±10 years, 44% paroxysmal) underwent a redo ablation for AF recurrences despite durable PVI at 39 centers. After durable PVI was confirmed, linear-based ablation was performed in 219 (60%) patients, electrogram-based ablation in 168 (45%) patients, trigger-based ablation in 101 (27%) patients, and pulmonary vein-based ablation in 56 (15%) patients. Seven patients (2%) did not undergo any additional ablation during the redo procedure. After 22±19 months of follow-up, 122 (33%) and 159 (43%) patients had a recurrence of atrial arrhythmia at 12 and 24 months, respectively. No significant difference in arrhythmia-free survival was observed between the different ablation strategies. Left atrial dilatation was the only independent factor associated with arrhythmia-free survival (HR, 1.59 [95% CI, 1.13–2.23]; P =0.006). Conclusions: In patients with recurrent AF despite durable PVI, no ablation strategy used alone or in combination during the redo procedure appears to be superior in improving arrhythmia-free survival. Left atrial size is a significant predictor of ablation outcome in this population.

Abstract: Aims Cardiac resynchronization therapy (CRT) is highly effective in dilated cardiomyopathy (DCM) patients with impaired left ventricular ejection fraction (LVEF) and left bundle block branch. In cardiac amyloidosis (CA) patients, left ventricular dysfunction and conduction defects are common, but the potential of CRT to improve cardiac remodelling and survival in this particular setting remains undefined. We investigated cardiovascular outcomes in CA patients after CRT implantation in terms of CRT echocardiographic response and major cardiovascular events (MACEs). Methods and results Our retrospective study included 47 CA patients implanted with CRT devices from January 2012 to February 2020, in nine French university hospitals (77 ± 6 years old, baseline LVEF 30 ± 8%) compared with propensity‐matched (1:1 for age, LVEF at implantation, and CRT indication) DCM patients with a CRT device. CA patients had lower rates of CRT response (absolute delta LVEF ≥ 10%) compared with DCM patients (36% vs. 70%, P = 0.002). After multivariate Cox analysis, CA was independently associated with MACE (hospitalization for heart failure/cardiovascular death) [hazard ratio (HR) 3.73, 95% confidence interval (CI) 1.85–7.54, P

9. Taquicardias supraventriculares en adultos (a excepción de la fibrilación auricular)

Author: Vincent Galand, Philippe Mabo, Raphaël P. Martins, and K. Benali
Subjects: Ocean Engineering, Safety, Risk, Reliability and Quality
Abstract: Resumen Las taquicardias supraventriculares (TSV) son un grupo de patologias ritmicas frecuentes en la practica clinica y que se originan en las auriculas o en la union auriculoventricular (AV). Por definicion, se contraponen a las taquicardias de origen ventricular con las que no comparten el riesgo hemodinamico y de muerte subita. Las principales arritmias agrupadas bajo este termino son la fibrilacion auricular, los cuadros de flutter auricular, las taquicardias auriculares, las taquicardias de la union y las taquicardias sinusales. El mecanismo fisiopatologico, la prevalencia y la asociacion con la cardiopatia subyacente difieren mucho entre estas distintas TSV. Sin embargo, estos diferentes aspectos deben estar bien integrados ya que condicionaran las respectivas modalidades de tratamiento de cada una de estas patologias. Su diagnostico suele ser electrocardiografico, pero puede requerir investigaciones mas complejas como la exploracion electrofisiologica. Su tratamiento puede basarse unicamente en la vigilancia, en la introduccion de tratamientos farmacologicos antiarritmicos o en la aplicacion de procedimientos de ablacion, dependiendo del tipo de trastorno del ritmo presente y de su tolerabilidad.

Abstract: Riassunto Le tachicardie sopraventricolari (TSV) corrispondono ad un gruppo di patologie ritmiche frequentemente riscontrate nella pratica clinica e originate negli atri o alla giunzione atrioventricolare (AV). Per definizione, sono opposte alle tachicardie di origine ventricolare, con le quali non condividono il rischio emodinamico e di morte improvvisa. Le principali aritmie raggruppate sotto questo termine sono la fibrillazione atriale, i flutter atriali, le tachicardie atriali, le tachicardie giunzionali e le tachicardie sinusali. Il meccanismo fisiopatologico, la prevalenza e l’associazione con una cardiopatia sottostante differiscono notevolmente tra queste diverse TSV. Tuttavia, questi diversi aspetti devono essere ben integrati poiche condizioneranno le rispettive modalita di gestione per ciascuna di queste patologie. La loro diagnosi e spesso elettrocardiografica, ma puo richiedere indagini piu complesse come l’esplorazione elettrofisiologica. Il loro trattamento puo basarsi sul solo monitoraggio, sull’introduzione di trattamenti farmacologici antiaritmici o sull’attuazione di procedure di ablazione a seconda del tipo di aritmia presente e della sua tolleranza.

Abstract: Brugada syndrome (BrS) is a cardiac arrhythmia disorder associated with sudden death in young adults. With the exception of SCN5A, encoding the cardiac sodium channel NaV1.5, susceptibility genes remain largely unknown. Here we performed a genome-wide association meta-analysis comprising 2,820 unrelated cases with BrS and 10,001 controls, and identified 21 association signals at 12 loci (10 new). Single nucleotide polymorphism (SNP)-heritability estimates indicate a strong polygenic influence. Polygenic risk score analyses based on the 21 susceptibility variants demonstrate varying cumulative contribution of common risk alleles among different patient subgroups, as well as genetic associations with cardiac electrical traits and disorders in the general population. The predominance of cardiac transcription factor loci indicates that transcriptional regulation is a key feature of BrS pathogenesis. Furthermore, functional studies conducted on MAPRE2, encoding the microtubule plus-end binding protein EB2, point to microtubule-related trafficking effects on NaV1.5 expression as a new underlying molecular mechanism. Taken together, these findings broaden our understanding of the genetic architecture of BrS and provide new insights into its molecular underpinnings.

Abstract: Left ventricular assist device (LVAD) implantation may be an attractive alternative therapeutic option for elderly patients with heart failure who are ineligible for heart transplantation.We aimed to describe the characteristics and outcomes of elderly patients (i.e. aged≥70 years) receiving an LVAD.This observational study was conducted in 19 centres between 2006 and 2016. Patients were divided into two groups-younger (aged70 years) and elderly (aged≥70 years), based on age at time of LVAD implantation.A total of 652 patients were included in the final analysis, and 74 patients (11.3%) were aged≥70 years at the time of LVAD implantation (maximal age 77.6 years). The proportion of elderly patients receiving an LVAD each year was constant, with a median of 10.6% (interquartile range 8.0-15.4%) per year, and all were implanted as destination therapy. Elderly and younger patients had similar durations of hospitalization in intensive care units and total lengths of hospital stays. Both age groups experienced similar rates of LVAD-related complications (i.e. stroke, bleeding, driveline infection and LVAD exchange), and the occurrence of LVAD complications did not impact survival in the elderly group compared with the younger group. Lastly, when compared with younger patients implanted as destination therapy, the elderly group also exhibited similar mid-term survival.This work strongly suggests that selected elderly adults can be scheduled for LVAD implantation.

Abstract: Objectives The aim of this multicenter study was to characterize the efficacy and safety of subcutaneous implantable cardioverter-defibrillators (S-ICDs) lead extraction procedures. Background S-ICDs have been developed to limit lead-related complications inherent to transvenous ICD devices. To date, no study has specifically investigated the safety and feasibility of S-ICD lead extraction procedures. Methods Patients requiring S-ICD lead extraction between February 1, 2014, and February 28, 2019, were retrospectively included in 10 centers. The primary endpoint of the study was procedural success, defined as the removal of all the lead and lead material from the subcutaneous space. Secondary endpoints included procedural complications and the need for specific extraction tools. Results S-ICD lead extraction procedures were performed in 32 patients (mean age 45.7 ± 13.8 years, 75.0% men, 65.6% in primary prevention). The median time from S-ICD lead implantation was 9.3 months (5.4 to 17.5 months). The primary endpoint, that is, complete removal of the material, was achieved in 96.9% of the patients, and only 1 procedural failure occurred (3.1%). Simple traction of the S-ICD lead was successful in 19 patients (59.4%), whereas 3 patients (9.4%) needed an additional incision and 9 patients (28.1%) required mechanical sheath to remove lead adhesions around the coil. No procedure-related complications occurred. Patients with successful simple traction extraction were implanted more recently (7.1 months [2.8 to 12.2 months] vs. 16.5 months [7.5 to 20.8 months]; p = 0.04) and had less prior history of sternotomy (2 [10.5%] vs. 5 [38.5%] patients; p = 0.09). Conclusions S-ICD lead extraction is an efficient and safe procedure, but may require some specific tools like mechanical sheath, specifically when fibrotic adhesions developed around the parasternal coil.

Abstract: OBJECTIVES Our goal was to provide a picture of left ventricular assist device (LVAD) activity in France between 2007 and 2016 based on the multicentric ASSIST-ICD registry. METHODS We retrospectively collected 136 variables including in-hospital data, follow-up survival rates and adverse events from 671 LVAD recipients at 20 out of 24 LVAD implant centres in France. The average follow-up time was 1.2 years (standard deviation: 1.4); the total follow-up time was 807.5 patient-years. RESULTS The included devices were the HeartMate II®, HeartWare LVAS® or Jarvik 2000®. The overall likelihood of being alive while on LVAD support or having a transplant (primary end point) at 1, 2, 3 and 5 years postimplantation was 65.2%, 59.7%, 55.9% and 47.7%, respectively, given a cumulative incidence of 29.2% of receiving a transplant at year 5. At implantation, 21.5% of patients were on extracorporeal life support. The overall rate of cardiogenic shock at implantation was 53%. The major complications were driveline infection (26.1%), pump pocket or cannula infection (12.6%), LVAD thrombosis (12.2%), ischaemic (12.8%) or haemorrhagic stroke (5.4%; all strokes 18.2%), non-cerebral haemorrhage (9.1%) and LVAD exchange (5.2%). The primary end point (survival) was stratified by age at surgery and by the type of device used, with inference from baseline profiles. The primary end point combined with an absence of complications (secondary end point) was also stratified by device type. CONCLUSIONS The ASSIST-ICD registry provides a real-life picture of LVAD use in 20 of the 24 implant centres in France. Despite older average age and a higher proportion of patients chosen for destination therapy, survival rates improved compared to those in previous national registry results. This LVAD registry contrasts with other international registries because patients with implants have more severe disease, and the national policy for graft attribution is distinct. We recommend referring patients for LVAD earlier and suggest a discussion of the optimal timing of a transplant for bridged patients (more dismal results after the second year of support?).

The later are sensitive to the direction of ventricular activation wavefronts. We aim to evaluate the impact of different ventricular activation wavefronts on the functional electrophysiological properties of myocardial tissue. Methods: Patients with ischemic heart disease referred for VT ablation underwent high-density mapping using Carto®3 (Biosense Webster). Maps were generated during sinus rhythm, right and left ventricular pacing, and analyzed using a new late potential map software, which allows to assess local conduction velocities and facilitates the delineation of intra-scar conduction corridors (ISCC); and for all stable VTs. Results: In 16 patients, 31 high-resolution substrate maps from different ventricular activation wavefronts and 7 VT activation maps were obtained. Local abnormal ventricular activities (LAVAs) were found in VT isthmus, but also in noncritical areas. The VT isthmus was localized in areas of LAVAs overlapping surface between the different activation wavefronts. The deceleration zone location differed depending on activation wavefronts. Sixty-six percent of ISCCs were similarly identified in all activating wavefronts, but the one acting as VT isthmus was simultaneously identified in all activation wavefronts in all cases. Conclusion: Functional based substrate mapping may improve the specificity to localize the most arrhythmogenic regions within the scar, making the use of different activation wavefronts unnecessary in most cases.

Abstract: Aims Up to 30% of selected heart failure patients do not benefit clinically from cardiac resynchronization therapy (CRT). Left ventricular (LV) wall thickness (WT) analysed using computed tomography (CT) has rarely been evaluated in response to CRT and mitral regurgitation (MR) improvement. We examined the association of LVWT and the ability to reverse LV remodelling and MR improvement after CRT. Methods and results Fifty-four patients scheduled for CRT underwent pre-procedural CT. Reduced LVWT was defined as WT Conclusion WT evaluated using CT could help to stratify the response to CRT and predict MR improvement and outcomes. Clinical trial registration NCT01097733.

Abstract: International audience; BACKGROUND: Increasing use of cardiovascular implantable electronic devices (CIED), as permanent pacemakers (PPM), implantable cardioverter defibrillators (ICD), or cardiac resynchronization therapy (CRT), is associated with the emergence of CIED-related infective endocarditis (CIED-IE). We aimed to characterize CIED-IE profile, temporal trends, and prognostic factors. METHODS: CIED-IE diagnosed at Rennes University Hospital during years 1992-2017 were identified through computerized database, and included if they presented all of the following: (1) clinical signs of infection; (2) microbiological documentation through blood and/or CIED lead cultures; (3) lead or valve vegetation, or definite IE according to Duke criteria. Data were retrospectively extracted from medical charts. The cohort was categorized in three periods: 1992-1999, 2000-2008, and 2009-2017. RESULTS: We included 199 patients (51 women, 148 men, median age 73 years [interquartile range, 64-79]), with CIED-IE: 158 PPMs (79%), 24 ICD (12%), and 17 CRT (9%). Main pathogens were coagulase-negative staphylococci (CoNS: n = 86, 43%), Staphylococcus aureus (n = 60, 30%), and other Gram-positive cocci (n = 28, 14%). Temporal trends were remarkable for the decline in CoNS (P = 0.002), and the emergence of S. aureus as the primary cause of CIED-IE (24/63 in 2009-2017, 38%). Factors independently associated with one-year mortality were chronic obstructive pulmonary disease (COPD: hazard ratio 3.84 [1.03-6.02], P = 0.03), left-sided endocarditis (HR 2.25 [1.09-4.65], P = 0.03), pathogens other than CoNS (HR 3.16 [1.19-8.39], P = 0.02), and CIED removal/reimplantation (HR 0.41 [0.20-0.83], P = 0.01). CONCLUSIONS: S. aureus has emerged as the primary cause of CIED-IE. Left-sided endocarditis, COPD, pathogens other than CoNS, and no CIED removal/reimplantation are independent risk factors for one-year mortality.

Abstract: International audience; Ventricular arrhythmias are serious life-threatening cardiac disorders. Despite many technological improvements, a non-negligible number of patients present refractory ventricular tachycardias, resistant to a catheter ablation procedure, placing these patients in a therapeutic impasse. Recently, a cardiac stereotactic radioablative technique has been developed to treat patients with refractory ventricular arrhythmias, as a bail out strategy. This new therapeutic option historically brings together two fields of expertise unknown to each other, pointing out the necessity of an optimal partnership between cardiologists and radiation oncologists. As described in this narrative review, the understanding of cardiological aspects of the technique for radiation oncologists and treatment technical aspects comprehension for cardiologists represent a major challenge for the application and the future development of this promising treatment.

Abstract: Background Temporary transvenous pacing in critically ill patients requiring prolonged cardiac pacing is associated with a high risk of complications. We sought to evaluate the safety and efficacy of self-contained intracardiac leadless pacemaker (LPM) implantation in this population. Methods and results Consecutive patients implanted with a Micra LPM during the hospitalization in an intensive care unit were retrospectively included. Inclusion criteria were: ≥1 supracaval central venous, or a ventilation tube, or intravenous antibiotic therapy for ongoing sepsis or bacteremia. Patients with a history of previous implantation of a pacemaker were excluded. Out of 1,016 patients implanted with an LPM, 99 met the inclusion criteria. Mean age was 75 years and Charlson comorbidity index 7. LPM implantation was successfully performed in 98% of cases, with a peri-operative complication rate of 5%, mainly cardiac injuries. In-hospital mortality rate was 6%. No late (>30 days) device-related complication occurred, especially no infection. Conclusions LPM appears as an acceptable alternative to conventional temporary transvenous pacing in selected critically ill patients requiring prolonged cardiac pacing, especially regarding the risk of infection.

Abstract: International audience; INTRODUCTION: The distance from the descending aorta (DA) to the posterior wall of the left atrium (LA) is variable. We aimed to determine whether the proximity between the DA and the left inferior pulmonary vein (LIPV) ostium has an impact on biophysical parameters and cryoballoon (CB) ablation efficacy during LIPV freezing. METHODS: Patients referred for CB-ablation of atrial fibrillation (AF) in two high-volume centers were included. Cryoablation data were collected prospectively for each patient. The anatomical relationships between the LIPV and the DA (distance LIPV ostium-DA, presence of an aortic imprint on the posterior aspect of the LIPV) were then retrospectively analysed on the LA computed tomography (CT) scans realized before AF ablation. RESULTS: 350 patients were included (70% men, 59.7±11.5 yo). The decrease in the Ostium-DA distance was significantly correlated to the increase in the Time-To-Isolation (TTI) (r=-0.31; p=0.036), with less negative temperature (r=-0.11; p=0.045). Similarly, the presence of an aortic imprint on the LIPV was associated with a longer TTI (p

Abstract: Aims The roles of implantable cardioverter-defibrillators (ICDs) and radiofrequency catheter ablation (RCA) in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC) and well-tolerated monomorphic ventricular tachycardia (MVT) are debated. In this multicentre retrospective study, we aimed at reporting the outcome of selected patients with ARVC after RCA without a back-up ICD. Methods and results Patients with ARVC who underwent RCA of well-tolerated MVT at 10 tertiary centres across 5 countries, without an ICD before and 3 months after RCA, without syncope or electrical storm, and with left ventricular ejection fraction ≥50% were included. In total, 65 ARVC patients [mean age 44.5 ± 13.2 years, 78% males] underwent RCA of MVT between 2003 and 2016. Clinical presentation was palpitations in 51 (80%) patients. One (2%) patient had >1 clinical MVT. At the ablative procedure, clinical MVTs (mean rate 185 ± 32 b.p.m.) were inducible in 50 (81%) patients. Epicardial ablation was performed in 19 (29%) patients. Complete acute success was achieved in 47 (72%) patients. After a median follow-up of 52.4 months (range 12.3–171.4), there was no death or aborted cardiac arrest, and VT recurred in 19 (29%) patients. Survival without VT recurrence was estimated at 88%, 80%, and 68%, 12, 36, and 60 months after RCA, respectively, and was significantly associated with the approach and the procedural outcome. Conclusion In patients with ARVC, well-tolerated MVT without a back-up ICD did not lead to fatal arrhythmic event after RCA despite VT recurrences in some. Our data suggest that RCA may be an alternative to ICD in selected ARVC patients.

Abstract: International audience; Objective We developed a detailed imaging phenotype of the cerebral complications in critically ill patients with infective endocarditis (IE) and determine whether any specific imaging pattern could impact prognostic information. Methods One hundred ninety-two patients admitted to the intensive care units of seven tertiary centers with severe, definite left IE and neurological complications were included. All underwent cerebral imaging few days after admission to define the types of lesions, their volumes, and their locations using voxel-based lesion-symptom mapping (VLSM). We employed uni- and multi-variate logistic regression analyses to explore the associations among imaging features and other prognostic variables and the 6-month modified Rankin Scale (mRS) score. Results Ischemic lesions were the most common lesions (75%; mean volume, 15.3 +/- 33 mL) followed by microbleeds (50%; mean number, 4 +/- 7.5), subarachnoidal hemorrhages (20%), hemorrhagic strokes (16%; mean volume, 14.6 +/- 21 mL), and hemorrhagic transformations (10%; mean volume, 5.6 +/- 11 mL). The volume of hemorrhagic transformations, the severity of leukopathy, and the compromises of certain locations on the motor pathway from the VLSM were associated with a poor 6-month mRS score on univariate analyses. However, upon multivariate analyses, no such specific imaging pattern independently predicted the mRS; this was instead influenced principally by age (OR = 1.03 [1.004-1.06]) and cardiac surgery status (OR = 0.06 [0.02-0.16]) in the entire cohort, and by age (OR= 1.04 [1.01-1.08]) and Staphylococcus aureus status (OR= 2.86 [1.19-6.89]) in operated patients. Conclusions In a cohort of severely ill IE patients with neurological complications, no specific imaging pattern could be highlighted as a reliable predictor of prognosis.

Abstract: International audience; The rate of permanent pacemaker (PPM) implantation is still growing in Europe, due in part to population ageing with an increased risk of developing conduction diseases. Although most PPM recipients are elderly patients, some young patients experience atrioventricular block (AVB) requiring PPM. In a recent study by Rudbeck-Resdal et al. evaluating AVB in young patients, the estimated incidence of developing AVB before 50 years of age was 17.7/year/million inhabitants throughout their 20-year nationwide study period.1 The aetiology of AVB was identified in only half of the patients. The most frequent causes were complications to cardiac surgery (15.3%), congenital AVB or congenital heart disease (9.0% and 4.2%, respectively), and cardioinhibitory reflex (5.0%). An underlying cardiomyopathy or sarcoidosis were uncommon causes in this specific population.

Abstract: Background: An accurate estimation of the risk of life-threatening (LT) ventricular tachyarrhythmia (VTA) in patients with LMNA mutations is crucial to select candidates for implantable cardioverter-defibrillator implantation. Methods: We included 839 adult patients with LMNA mutations, including 660 from a French nationwide registry in the development sample, and 179 from other countries, referred to 5 tertiary centers for cardiomyopathies, in the validation sample. LTVTA was defined as (1) sudden cardiac death or (2) implantable cardioverter defibrillator–treated or hemodynamically unstable VTA. The prognostic model was derived using the Fine-Gray regression model. The net reclassification was compared with current clinical practice guidelines. The results are presented as means (SD) or medians [interquartile range]. Results: We included 444 patients, 40.6 (14.1) years of age, in the derivation sample and 145 patients, 38.2 (15.0) years, in the validation sample, of whom 86 (19.3%) and 34 (23.4%) experienced LTVTA over 3.6 [1.0–7.2] and 5.1 [2.0–9.3] years of follow-up, respectively. Predictors of LTVTA in the derivation sample were: male sex, nonmissense LMNA mutation, first degree and higher atrioventricular block, nonsustained ventricular tachycardia, and left ventricular ejection fraction (https://lmna-risk-vta.fr). In the derivation sample, C-index (95% CI) of the model was 0.776 (0.711–0.842), and the calibration slope 0.827. In the external validation sample, the C-index was 0.800 (0.642–0.959), and the calibration slope was 1.082 (95% CI, 0.643–1.522). A 5-year estimated risk threshold ≥7% predicted 96.2% of LTVTA and net reclassified 28.8% of patients with LTVTA in comparison with the guidelines-based approach. Conclusions: In comparison with the current standard of care, this risk prediction model for LTVTA in laminopathies significantly facilitated the choice of candidates for implantable cardioverter defibrillators.

Abstract: International audience; Ablation of atrial fibrillation (AF) is the cornerstone therapy for patients with symptomatic AF resistant to anti-arrhythmic drugs or as first-line therapy, and is based on permanent pulmonary vein (PV) isolation. The presence of a conduction gap in a wide antral circumferential ablation lesion around PVs is often sufficient to transform an initially successful ablation into a procedural failure, thus necessitating a redo intervention. The strategy during a redo procedure is based on the detection and ablation of the reconnection gap. Finding gaps is often simple, but also sometimes challenging, because gaps may be difficult to detect, resulting in unnecessary radiofrequency delivery. The present review aimed to describe the various techniques published thus far to detect residual reconnections along the encircling ablation lines around PVs, to help electrophysiologists to detect and ablate reconnection gaps. © 2019 American College of Cardiology Foundation

Abstract: The field of cardiac electrophysiology has greatly developed during the past decades. Consequently, the use of electrophysiological studies (EPSs) in clinical practice has also significantly augmented, with a progressively increasing number of certified electrophysiology centers and specialists. Since Zipes et al published the Guidelines for Clinical Intracardiac Electrophysiology and Catheter Ablation Procedures in 1995, no official document summarizing current EPS indications has been published.The current paper focuses on summarizing all relevant data of the role of EPS in patients with different types of cardiac pathologies and provides up-to-date recommendations on this topic.For this purpose, the PubMed database was screened for relevant articles in English up to December 2018 and ESC and ACC/AHA Clinical Practice Guidelines, and EHRA/HRS/APHRS position statements related to the current topic were analyzed.Current recommendations for the use of EPS in clinical practice are discussed and presented in 17 distinct cardiac pathologies. A short rationale, evidence, and indications are provided for each cardiac disease/group of diseases.In conclusion, because of its capability to establish a diagnosis in patients with a variety of cardiac pathologies, the EPS remains a useful tool in the evaluation of patients with cardiac arrhythmias and conduction disorders and is capable of establishing indications for cardiac device implantation and guide catheter ablation procedures.

Abstract: Idiopathic or iatrogenic left bundle branch block (LBBB) is a unique model of electro-mechanical ventricular dyssynchrony with concordant changes in electrical activation sequence and mechanical ventricle synchronization. In chronic animal models, isolated LBBB induces structural remodeling with progressive left ventricular (LV) dysfunction. Most abnormalities can be reverted after cardiac resynchronization therapy (CRT). In humans, 2 principal models of LBBB dyssynchronopathy can be observed: the chronic model of isolated LBBB and an acute iatrogenic model of new-onset LBBB after aortic valve interventions. Although epidemiological evidence and clinical data need to be strengthened, there is a strong presumption that they may lead to LBBB-induced cardiomyopathy and benefit from CRT to prevent progression to heart failure. A large cohort study with prospective follow-up would be required to better define actual incidence, evolution over time, and predisposing factors. Parallel randomized CRT clinical trials should be conducted in selected at-risk populations: namely, patients with persistent LBBB after transcatheter aortic valve replacement.

Abstract: Graphical abstract Incidence of ventricular arrhythmias per week compared with the number of new coronavirus disease 2019 (COVID-19) cases per week in France (blue line) and the daily percentage of COVID-19 information on 24-hour television information channels per week (red line). TV: television; VF: ventricular fibrillation; VT: ventricular tachycardia., Background The coronavirus disease 2019 (COVID-19) has been a fast-growing worldwide pandemic. Aims We aimed to investigate the incidence of cardiac arrhythmias among a large French cohort of implantable cardioverter defibrillator recipients over the first 5 months of 2020. Methods Five thousand nine hundred and fifty-four implantable cardioverter defibrillator recipients were followed by remote monitoring during the COVID-19 period (from 01 January to 31 May 2020). Data were obtained from automated remote follow-up of implantable cardioverter defibrillators utilizing the Implicity® platform. For all patients, the type of arrhythmia (atrial fibrillation, ventricular tachycardia or ventricular fibrillation), the number of ventricular arrhythmia episodes and the type of implantable cardioverter defibrillator-delivered therapy were recorded. Results A total of 472 (7.9%) patients presented 4917 ventricular arrhythmia events. An increase in ventricular arrhythmia incidence was observed after the first COVID-19 case in France, and especially during weeks #10 and #11, at the time of major governmental measures, with an increase in the incidence of antitachycardia pacing delivered therapy. During the 11 weeks before the lockdown order, the curve of the percentage of live-stream television coverage of COVID-19 information matched the ventricular arrhythmia incidence. During the lockdown, the incidence of ventricular arrhythmia decreased significantly compared with baseline (0.05 ± 0.7 vs. 0.09 ± 1.2 episodes per patient per week, respectively; P

Abstract: International audience; Objectives: This study aimed to assess the impact of pulmonary valve replacement (PVR) on ventricular arrhythmias burden in a population of tetralogy of Fallot (TOF) patients with continuous cardiac monitoring by implantable cardioverter-defibrillators (ICDs).Background: Sudden cardiac death is a major cause of death in TOF, and right ventricular overload is commonly considered to be a potential trigger for ventricular arrhythmias.Methods: Data were analyzed from a nationwide French ongoing study (DAI-T4F) including all TOF patients with an ICD since 2000. Survival data with recurrent events were used to compare the burden of appropriate ICD therapies before and after PVR in patients who underwent PVR over the study period.Results: A total of 165 patients (mean age 42.2 ± 13.3 years, 70.1% male) were included from 40 centers. Over a median follow-up period of 6.8 (interquartile range: 2.5 to 11.4) years, 26 patients (15.8%) underwent PVR. Among those patients, 18 (69.2%) experienced at least 1 appropriate ICD therapy. When considering all ICD therapies delivered before (n = 62) and after (n = 16) PVR, the burden of appropriate ICD therapies was significantly lower after PVR (HR: 0.21; 95% confidence interval [CI]: 0.08 to 0.56; p = 0.002). Respective appropriate ICD therapies rates per 100 person-years were 44.0 (95% CI: 35.7 to 52.5) before and 13.2 (95% CI: 7.7 to 20.5) after PVR (p < 0.001). In the overall cohort, PVR before ICD implantation was also independently associated with a lower risk of appropriate ICD therapy in primary prevention patients (HR: 0.29 [95% CI: 0.10 to 0.89]; p = 0.031).Conclusions: In this cohort of high-risk TOF patients implanted with an ICD, the burden of appropriate ICD therapies was significantly reduced after PVR. While optimal indications and timing for PVR are debated, these findings suggest the importance of considering ventricular arrhythmias in the overall decision-making process.

Abstract: International audience; Conduction disturbances remain common following transcatheter aortic valve implantation (TAVI). Aside from high-degree atrioventricular block (HAVB), their optimal management remains elusive. Invasive electrophysiological studies (EPS) may help stratify patients at low or high risk of HAVB allowing for an early discharge or permanent pacemaker (PPM) implantation among patients with conduction disturbances. We evaluated the safety and diagnostic performances of an EPS-guided PPM implantation strategy among TAVI recipients with conduction disturbances not representing absolute indications for PPM. All patients who underwent TAVI at a single expert center from June 2017 to July 2020 who underwent an EPS during the index hospitalization were included in the present study. False negative outcomes were defined as patients discharged without PPM implantation who required PPM for HAVB within 6 months of the initial EPS. False positive outcomes were defined as patients discharged with a PPM with a ventricular pacing percentage < 1% at follow-up. A total of 78 patients were included (median age: 82.4 years, 38% female), among whom 35 patients (45%) received a PPM following EPS. The sensitivity, specificity, positive and negative predictive values of the EPS-guided PPM implantation strategy were 100%, 89.6%, 81.5%, and 100%, respectively. Six patients suffered a mechanical HAVB during EPS and received a PPM. These 6 patients showed PPM dependency at follow-up. In conclusion, an EPS-guided PPM implantation strategy for managing post-TAVI conduction disturbances appears effective to identify patients who can be safely discharged without PPM implantation.

Abstract: Introduction Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease, and sudden cardiac death represents an important mode of death in these patients. Data evaluating the implantable cardioverter defibrillator (ICD) in this patient population remain scarce. Objective We aimed to describe long-term follow-up of TOF patients implanted with ICD through a nationwide French registry. Methods Nationwide French Registry including all TOF patients with an ICD initiated in 2010 by the French Institute of Health and Medical Research. The primary time to event endpoint was the time from ICD implantation to first appropriate ICD therapy. Clinical events were centrally adjudicated by a blinded committee. Results A total of 165 patients (mean age 42.2 ± 13.3 years, 70.1% males) were included from 40 centers, including 104 (63.0%) in secondary prevention. During a median (IQR) follow-up of 6.8 (2.5–11.4) years, 78 (47.3%) patients received at least one appropriate ICD therapy. The annual incidence of the primary outcome was 10.5% (7.1% and 12.5% in primary and secondary prevention, respectively, P = 0.03). Overall, 71 (43.0%) patients presented with at least one ICD complication, including inappropriate shocks in 42 (25.5%) patients and lead dysfunction in 36 (21.8%) patients. Among 61 (37.0%) primary prevention patients, the annual rate of appropriate ICD therapies was 4.1%, 5.3%, 9.5%, and 13.3% in patients with respectively no, one, two, or ≥ three guideline-recommended risk factors. QRS fragmentation was the only independent predictor of appropriate ICD therapies (HR 3.47, 95% CI 1.19–10.11), and its integration in a model with current criteria increased the 5-year time-dependent area under the curve from 0.68 to 0.81 (P = 0.006) ( Fig. 1 ). Conclusions Patients with TOF and an ICD experience high rates of appropriate therapies, including those implanted in primary prevention. The considerable long-term burden of ICD-related complications, however, underlines the need for careful candidate selection. A combination of easy-to-use criteria including QRS fragmentation might improve risk stratification.

Abstract: International audience; Objectives This study sought to validate the performance of the VT-LVAD risk model in predicting late ventricular arrhythmias (VAs) in patients after left ventricular assist device (LVAD) implantation. Background The need for implantable cardioverter-defibrillator (ICD)-implantation in LVAD recipients is not well studied. A better selection of the patients with high risk for late VAs could lead to a more targeted ICD-implantation or replacement. Methods The study evaluated the performance of the VT-LVAD prognostic score (VAs prior LVAD, no ACE-inhibitor in medication, heart failure duration > 12 months, early VAs post-LVAD implantation, atrial fibrillation prior LVAD, idiopathic dilated cardiomyopathy) for the endpoint of the occurrence of late VAs in 357 LVAD patients in Heart Centre of Leipzig. Results From the initial 460 patients, 357 (age: 58 +/- 10 years; left ventricular ejection fraction: 20 +/- 6%; HeartWare: 50%; HeartMate III: 42%) were assigned to four risk groups according to their VT-LVAD score varying from low risk to very high risk. After 25 months, late VAs occurred in 130 patients. The VT-LVAD score was an independent predictor of late VAs (multivariate analysis; p = < .001; goodness-of-tip p = .347; odds ratio: 4.8). While there was no statistically significant difference between the low- and intermediate-risk group, risk stratification for patients with high risk and very high risk performed more accurately (pairwise comparison p = .005 and p < .001, respectively). Conclusions The VT-LVAD score predicted accurately the occurrence of late VAs in high-risk LVAD recipients in a large external cohort of LVAD recipients supporting its utility for more targeted ICD implantations.

Abstract: International audience; LVAD implantation in patients with a recently diagnosed cardiomyopathy has been poorly investigated. This work aims at describing the characteristics and outcomes of patients receiving a LVAD within 30 days following the diagnosis of cardiomyopathy. Patients from the ASSIST-ICD study was divided into recently and remotely diagnosed cardiomyopathy based on the time from initial diagnosis of cardiomyopathy to LVAD implantation using the cut point of 30 days. The primary end point of the study was all-cause mortality at 30-day and during follow-up. A total of 652 patients were included and followed during a median time of 9.1 (2.5 to 22.1) months. In this population, 117 (17.9%) had a recently diagnosed cardiomyopathy and had LVAD implantation after a median time of 15.0 (9.0 to 24.0) days following the diagnosis. This group of patients was significantly younger, with more ischemic cardiomyopathy, more sudden cardiac arrest (SCA) events at the time of the diagnosis and were more likely to receive temporary mechanical support before LVAD compared with the remotely diagnosed group. Postoperative in-hospital survival was similar in groups, but recently diagnosed patients had a better long-term survival after hospital discharge. SCA before LVAD and any cardiac surgery combined with LVAD implantation were identified as 2 independent predictors of postoperative mortality in recently diagnosed patients. In conclusion, rescue LVAD implantation for recently diagnosed severe cardiomyopathy is common in clinical practice. Such patients experience a relatively low postoperative mortality and have a better long-term survival compared with remotely diagnosed patients.

Abstract: International audience; In our healthcare system, mindful of patient safety and the reduction of medical errors, simulation-based training has emerged as the cornerstone of medical education, allowing quality training in complete safety for patients. Initiated by anaesthesiologists, this teaching mode effectively allows a gradual transfer of learning, and has become an essential tool in cardiology teaching. Cardiologists are embracing simulation to master complex techniques in interventional cardiology, to manage crisis situations and unusual complications and to develop medical teamwork. Simulation methods in cardiology include high-fidelity simulators, clinical scenarios, serious games, hybrid simulation and virtual reality. Simulation involves all fields of cardiology: transoesophageal echocardiography, cardiac catheterization, coronary angioplasty and electrophysiology. Beyond purely technical issues, simulation can also enhance communication skills, by using standardized patients, and can improve the management of situations related to the announcement of serious diseases. In this review of recent literature, we present existing simulation modalities, their applications in different fields of cardiology and their advantages and limitations. Finally, we detail the growing role for simulation in the teaching of medical students following the recent legal obligation to use simulation to evaluate medical students in France.

Abstract: International audience; Background - Cryoballoon ablation is widely used for pulmonary vein isolation in patients with atrial fibrillation. There are no data regarding the clinical efficacy of cryoballoon ablation in patients with atypical right pulmonary vein anatomy. Aim - We aimed to evaluate the impact of right pulmonary vein anatomy on the safety and efficacy of cryoballoon ablation. Methods - Patients referred for cryoballoon ablation of paroxysmal atrial fibrillation were enrolled prospectively. Left atrial computed tomography was performed before cryoballoon ablation to determine whether the right pulmonary vein anatomy was "normal" or "atypical". For patients with atypical anatomy, cryoballoon ablation was only performed for right superior and right inferior pulmonary veins, neglecting accessory pulmonary veins. Results - Overall, 303 patients were included: 254 (83.8%) with normal and 49 (16.2%) with atypical right pulmonary vein anatomy. First-freeze isolation for right superior and right inferior pulmonary veins occurred in 44 (89.8%) and 37 (75.5%) patients with atypical pulmonary vein anatomy, and in 218 (85.8%) and 217 (85.4%) patients with typical pulmonary vein anatomy, respectively (P not significant). Phrenic nerve palsies were only observed in patients with normal anatomy (0 vs. 26 [8.6%]; P=0.039). Mid-term survival free from atrial arrhythmia was similar, regardless of right pulmonary vein anatomy. Conclusions - A significant proportion of patients have atypical right pulmonary vein anatomy. Procedural characteristics, acute pulmonary vein isolation success and mid-term procedural efficacy were similar, regardless of right pulmonary vein anatomy. In addition to left-side pulmonary vein isolation, cryoballoon ablation of right superior and right inferior pulmonary veins only, neglecting accessory pulmonary veins, is sufficient to obtain acute right-side pulmonary vein isolation and mid-term sinus rhythm maintenance in patients with atypical anatomy.

Abstract: International audience; We aimed at characterizing the impact of low and high body mass index (BMI) on outcomes after left-ventricular assist device (LVAD) surgery and define the predictors of mortality in patients with abnormal BMI (low/high). This study was conducted in 19 centers from 2006 to 2016. Patients were divided based on their baseline BMI into 3 groups of BMI: low (BMI ≤18.5 kg/m²); normal (BMI = 18.5 to 24.99 kg/m²) and high (BMI ≥25 kg/m²) (including overweight (BMI = 25 to 29.99 kg/m²), and obesity (BMI ≥30 Kg/m²)). Among 652 patients, 29 (4.4%), 279 (42.8%) and 344 (52.8%) had a low-, normal-, and high BMI, respectively. Patients with high BMI were significantly more likely men, with more co-morbidities and more history of ventricular/supra-ventricular arrhythmias before LVAD implantation. Patients with abnormal BMI had significantly lower survival than those with normal BMI. Notably, those with low BMI experienced the worst survival whereas overweight or obese patients had similar survival. Four predictors of mortality for LVAD candidates with abnormal BMI were defined: total bilirubin ≥16 µmol/L before LVAD, hypertension, destination therapy, and cardiac surgery with LVAD. Depending on the number of predictor per patients, those with abnormal BMI may be divided in 3 groups of 1-year mortality risk, i.e., low (0 to 1 predictor: 29% and 31%), intermediate (2 to 3 predictors, 51% and 52%, respectively), and high (4 predictors: 83%). In conclusion, LVAD recipients with abnormal BMI experience lower survival, especially underweight patients. Four predictors of mortality have been identified for LVAD population with abnormal BMI, differentiating those a low-, intermediate-, and high risks of death.

Abstract: Purpose: Stringent variant interpretation guidelines can lead to high rates of variants of uncertain significance (VUS) for genetically heterogeneous disease like long QT syndrome (LQTS) and Brugada syndrome (BrS). Quantitative and disease-specific customization of American College of Medical Genetics and Genomics/Association for Molecular Pathology (ACMG/AMP) guidelines can address this false negative rate. Methods: We compared rare variant frequencies from 1847 LQTS (KCNQ1/KCNH2/SCN5A) and 3335 BrS (SCN5A) cases from the International LQTS/BrS Genetics Consortia to population-specific gnomAD data and developed disease-specific criteria for ACMG/AMP evidence classes-rarity (PM2/BS1 rules) and case enrichment of individual (PS4) and domain-specific (PM1) variants. Results: Rare SCN5A variant prevalence differed between European (20.8%) and Japanese (8.9%) BrS patients (p = 5.7 x 10(-18)) and diagnosis with spontaneous (28.7%) versus induced (15.8%) Brugada type 1 electrocardiogram (ECG) (p = 1.3 x 10(-13)). Ion channel transmembrane regions and specific N-terminus (KCNH2) and C-terminus (KCNQ1/KCNH2) domains were characterized by high enrichment of case variants and >95% probability of pathogenicity. Applying the customized rules, 17.4% of European BrS and 74.8% of European LQTS cases had (likely) pathogenic variants, compared with estimated diagnostic yields (case excess over gnomAD) of 19.2%/82.1%, reducing VUS prevalence to close to background rare variant frequency. Conclusion: Large case-control data sets enable quantitative implementation of ACMG/AMP guidelines and increased sensitivity for inherited arrhythmia genetic testing., Amsterdam Cardiovascular Sciences fellowship; Dutch Heart Foundation (CVON Predict-2/Concor-genes); Netherlands Organization for Scientific ResearchNetherlands Organization for Scientific Research (NWO) [VICI 016.150.610]; Fondation LeducqLeducq Foundation, R.W. is supported by an Amsterdam Cardiovascular Sciences fellowship.

Abstract: Background Implantable cardioverter-defibrillator (ICD) lead dysfunction has been reported after left ventricular assist device (LVAD) implantation in limited single-center studies. We aimed at describing and characterizing the incidence of ICD lead parameters dysfunction after LVAD implantation. Methods Among the 652 patients enrolled in the ASSIST-ICD study, only patients with an ICD prior to LVAD were included (n = 401). ICD lead parameters dysfunction following LVAD implantation is defined as follows: (a) >50% decrease in sensing threshold, (b) pacing lead impedance increase/decrease by >100Ω, and (c) >50% increase in pacing threshold. Results One hundred twenty-two patients with an ICD prior to LVAD had available ICD interrogation reports prior and after LVAD. A total of 67 (55%) patients exhibited at least one significant lead dysfunction: 17 (15%) exhibited >50% decrease in right ventricular (RV) sensing, 51 (42%) had >100 Ω increase/decrease in RV pacing impedance, and 24 (20%) experienced >50% increase in RV pacing threshold. A total of 52 patients experienced ventricular arrhythmia during follow-up and all were successfully detected and treated by the device. All lead dysfunction could be managed conservatively. Conclusion More than 50% of LVAD-recipients may experience >1 significant change in lead parameters but none had severe clinical consequences.

Abstract: International audience; The impact of uncommon etiology cardiomyopathies on Left-ventricular assist device (LVAD)-recipient outcomes is not very well known. This study aimed to characterize patients with uncommon cardiomyopathy etiologies and examine the outcomes between uncommon and ischemic/idiopathic dilated cardiomyopathy. This observational study was conducted in 19 centers between 2006 and 2016. Baseline characteristics and outcomes of patients with uncommon etiology were compared to patients with idiopathic dilated/ischemic cardiomyopathies. Among 652 LVAD-recipients included, a total of 590 (90.5%) patients were classified as ischemic/idiopathic and 62 (9.5%) patients were classified in the "uncommon etiologies" group. Main uncommon etiologies were: hypertrophic (n = 12(19%)); cancer therapeutics-related cardiac dysfunction (CTRCD) (n = 12(19%)); myocarditis (n = 11(18%)); valvulopathy (n = 9(15%)) and others (n = 18(29%)). Patients with uncommon etiologies were significantly younger with more female and presented less co-morbidities. Additionally, patients with uncommon cardiomyopathies were less implanted as destination therapy compared with ischemic/idiopathic group (29% vs 38.8%). During a follow-up period of 9.1 months, both groups experienced similar survival. However, subgroup of hypertrophic/valvular cardiomyopathies and CTRCD had significantly higher mortality compared to the ischemic/idiopathic or myocarditis/others cardiomyopathies. Conversely, patients with myocarditis/others etiologies experienced a better survival. Indeed, the 12-months survival in the myocarditis/others; ischemic/idiopathic and hypertrophic/CTRCD/valvulopathy group were 77%; 65%, and 46% respectively. In conclusion, LVAD-recipients with hypertrophic cardiomyopathy, valvular heart disease and CTRCD experienced the higher mortality rate.

Abstract: The aim of this multicenter study was to characterize the efficacy and safety of subcutaneous implantable cardioverter-defibrillators (S-ICDs) lead extraction procedures.S-ICDs have been developed to limit lead-related complications inherent to transvenous ICD devices. To date, no study has specifically investigated the safety and feasibility of S-ICD lead extraction procedures.Patients requiring S-ICD lead extraction between February 1, 2014, and February 28, 2019, were retrospectively included in 10 centers. The primary endpoint of the study was procedural success, defined as the removal of all the lead and lead material from the subcutaneous space. Secondary endpoints included procedural complications and the need for specific extraction tools.S-ICD lead extraction procedures were performed in 32 patients (mean age 45.7 ± 13.8 years, 75.0% men, 65.6% in primary prevention). The median time from S-ICD lead implantation was 9.3 months (5.4 to 17.5 months). The primary endpoint, that is, complete removal of the material, was achieved in 96.9% of the patients, and only 1 procedural failure occurred (3.1%). Simple traction of the S-ICD lead was successful in 19 patients (59.4%), whereas 3 patients (9.4%) needed an additional incision and 9 patients (28.1%) required mechanical sheath to remove lead adhesions around the coil. No procedure-related complications occurred. Patients with successful simple traction extraction were implanted more recently (7.1 months [2.8 to 12.2 months] vs. 16.5 months [7.5 to 20.8 months]; p = 0.04) and had less prior history of sternotomy (2 [10.5%] vs. 5 [38.5%] patients; p = 0.09).S-ICD lead extraction is an efficient and safe procedure, but may require some specific tools like mechanical sheath, specifically when fibrotic adhesions developed around the parasternal coil.

Abstract: International audience; The residual risk of ventricular arrhythmia (VA) after cardiac resynchronization therapy (CRT) implantation in patients with nonischemic cardiomyopathy (NICM) remains difficult to evaluate. The impact of left ventricular (LV) wall thickness (WT) measured using computed tomography (CT) on the occurrence of VA after CRT implantation has never been investigated. In this pilot study, we examined the association of LV WT and the occurrence of VA in NICM patients receiving CRT. Thirty three patients with NICM scheduled for CRT underwent preprocedural CT. Reduced LV WT was defined as WT
