RESUMEN
There is an increasing proportion of the general population surviving to old age with significant chronic disease, multi-morbidity, and disability. The prevalence of pre-frail state and frailty syndrome increases exponentially with advancing age and is associated with greater morbidity, disability, hospitalization, institutionalization, mortality, and health care resource use. Frailty represents a global problem, making early identification, evaluation, and treatment to prevent the cascade of events leading from functional decline to disability and death, one of the challenges of geriatric and general medicine. Cardiac arrhythmias are common in advancing age, chronic illness, and frailty and include a broad spectrum of rhythm and conduction abnormalities. However, no systematic studies or recommendations on the management of arrhythmias are available specifically for the elderly and frail population, and the uptake of many effective antiarrhythmic therapies in these patients remains the slowest. This European Heart Rhythm Association (EHRA) consensus document focuses on the biology of frailty, common comorbidities, and methods of assessing frailty, in respect to a specific issue of arrhythmias and conduction disease, provide evidence base advice on the management of arrhythmias in patients with frailty syndrome, and identifies knowledge gaps and directions for future research.

AIM: The implementation of 3D mapping systems plays an important role in interventional electrophysiology (EP) in recent years. The aim of the present study was to evaluate use of 3D mapping systems regarding fluoroscopy and procedure duration. METHOD: In the "Go for Zero Fluoroscopy" project 25 European centers provided data of consecutive EP procedures. Data on use of 3D mapping systems as well as utilization of contact force catheters and multipolar mapping catheters were associated with fluoroscopy time, dose area product (DAP), and procedure duration. RESULT: A 3D mapping system was used in 966 (54%) cases. Use of 3D mapping for atrioventricular nodal reentry tachycardia (AVNRT) was associated with reduced fluoroscopy time (p < 0.001), DAP (p = 0.04) but increased procedure time (p = 0.029). Moreover, fluoroscopy time (p < 0.001) and DAP (p = 0.005) were significantly lower in the 3D mapping group in ablation of typical atrial flutter. However, the procedure time (p < 0.001) increased. Use of 3D mapping in the ablation of accessory pathway (AP) was associated with reduced fluoroscopy time (p < 0.001) and DAP (p < 0.001) with no significant increase in procedure time (p = 0.066). In the case of atrial fibrillation, a 3D mapping system was used in 485 patients (75.8%). Additional use of a contact force catheter was associated with lower fluoroscopy time (p < 0.001) and DAP (p < 0.001). Use of a multipolar mapping catheter was associated with lower fluoroscopy time (p = 0.002). The implementation of 3D mapping systems in the ablation of ventricular tachycardias resulted in a significant increase in the procedure time (p = 0.001) without significant differences regarding the DAP (p = 0.773) and fluoroscopy time (p = 0.249). CONCLUSION: Use of 3D mapping systems in ablation of supraventricular tachycardias is associated with lower radiation exposure. Nevertheless, the procedure time often increases, except in the case of ablation for AP. Use of contact force catheters and multipolar mapping catheters is associated with yet lower radiation exposure values. Prospective randomized studies are needed to further elucidate potential benefit of these technological tools.

Social media (SoMe) represents a medium of communication in everyday life and has gained importance for professional use among clinicians. In the #intEHRAct survey, we aimed to describe the use of SoMe by the healthcare community in a professional setting. The EHRA e-Communication Committee and the Scientific Initiatives Committee prepared a questionnaire and distributed it via newsletters, Twitter, LinkedIn, and Facebook. The survey consisted of 19 questions made on an individual basis and collected anonymously. Two hundred and eighty-five responders from 35 countries (72.3% male, age 49 ± 11 years old) completed the survey. Most respondents (42.7%) declared to use SoMe as passive users while 38.3% and 19.0% declared to share content on a non-daily and daily basis, respectively. The respondents estimated they spent a median of 5 (Q1-Q3: 2-10) h per week on SoMe. The most widely used SoMe was LinkedIn (60.8%), but the use of each platform was heterogeneous between countries. Among the advantages of SoMe, respondents indicated the chance of being updated on recent publications (66.0%), networking (48.5%), and the availability of rare or interesting cases (47.9%) as the most useful. Regarding the disadvantages of SoMe, the respondents underlined the loss of personal contact (40.7%), the inability to get 'hands-on' training (38.7%), and the lack of control regarding quality of scientific evidence (37.1%). Social media is increasingly used for professional purposes for scientific updating, networking, and case-based learning. The results of this survey encourage scientific societies, journals, and authors to enhance the quality, reach and impact of scientific content provided through SoMe.

The use of a blanking period (BP) after an atrial fibrillation (AF) ablation procedure is a common practice, but recent data questions the benign nature of early recurrences of atrial tachyarrhythmias (ERATs). A physician-based survey was carried out by the European Heart Rhythm Association (EHRA) to investigate the current definition and applicability of BP and ERAT management. An online questionnaire was sent to clinical and interventional electrophysiologists. A total of 436 respondents (88% interventional electrophysiologists) reported observing ERATs in 25% (interquartile range 15-35) of patients, less commonly in paroxysmal AF (PAF) compared with persistent AF (persAF). The median reported duration of BP used by respondents was 90 days, with 22% preferring a shorter BP duration for PAF patients compared with persAF. Half of the patients with ERATs are expected to also experience late recurrences (LR). Isolated episodes of ERATs are treated conservatively by 99% of the respondents, but repeat ablation during the BP is preferred by 20% of electrophysiologists for multiple ERATs and by 16% in patients with organized atrial tachyarrhythmias. In conclusion, ERATs are commonly observed after AF ablation, particularly in persAF patients, and are perceived as predictors of LR by half of the respondents. A general adherence to a 90-day BP duration was observed. During this time period, ERAT is mainly treated conservatively, but repeat ablation during the BP is occasionally offered to patients with multiple ERATs and those with organized atrial tachyarrhythmias.

The aims of this centre-based survey, promoted and disseminated by the European Heart Rhythm Association (EHRA) was to investigate the current practice for the investigation of Sudden Unexplained Death in the Young (SUDY) amongst European countries. An online questionnaire composed of 21 questions was submitted to the EHRA Research Network, European Cardiac Arrhythmia Genetics (ECGen) Focus Group members, and European Reference Network GUARD-Heart healthcare partners. There were 81 respondents from 24 European countries. The majority (78%) worked in a dedicated clinic focusing on families with inherited cardiac conditions and/or SUDY or had easy access to a nearby one. On average, an autopsy was performed in 43% of SUDY cases. Macroscopic examination of the body and all organs were completed in 71% of cases undergoing autopsy, and expert cardiac examination in 32%. Post-mortem genetic testing was requested on average in 37% of Sudden Arrhythmic Death Syndrome (SADS) cases, but not at all by 20% of survey respondents. Psychological support and bereavement counselling for SADS/SUDY families were available for ≤50% of participants. Whilst electrocardiogram (ECG) and echocardiography were largely employed to investigate SADS relatives, there was an inconsistent approach to the use of provocative testing with exercise ECG, sodium channel blocking drugs, and/or epinephrine and genetic testing. The survey highlighted a significant heterogeneity of service provision and variable adherence to current recommendations for the investigation of SUDY, partly attributable to the availability of dedicated units and specialist tests, genetic evaluation, and post-mortem examination.

We aim to provide a critical appraisal of basic concepts underlying signal recording and processing technologies applied for (i) atrial fibrillation (AF) mapping to unravel AF mechanisms and/or identifying target sites for AF therapy and (ii) AF detection, to optimize usage of technologies, stimulate research aimed at closing knowledge gaps, and developing ideal AF recording and processing technologies. Recording and processing techniques for assessment of electrical activity during AF essential for diagnosis and guiding ablative therapy including body surface electrocardiograms (ECG) and endo- or epicardial electrograms (EGM) are evaluated. Discussion of (i) differences in uni-, bi-, and multi-polar (omnipolar/Laplacian) recording modes, (ii) impact of recording technologies on EGM morphology, (iii) global or local mapping using various types of EGM involving signal processing techniques including isochronal-, voltage- fractionation-, dipole density-, and rotor mapping, enabling derivation of parameters like atrial rate, entropy, conduction velocity/direction, (iv) value of epicardial and optical mapping, (v) AF detection by cardiac implantable electronic devices containing various detection algorithms applicable to stored EGMs, (vi) contribution of machine learning (ML) to further improvement of signals processing technologies. Recording and processing of EGM (or ECG) are the cornerstones of (body surface) mapping of AF. Currently available AF recording and processing technologies are mainly restricted to specific applications or have technological limitations. Improvements in AF mapping by obtaining highest fidelity source signals (e.g. catheter-electrode combinations) for signal processing (e.g. filtering, digitization, and noise elimination) is of utmost importance. Novel acquisition instruments (multi-polar catheters combined with improved physical modelling and ML techniques) will enable enhanced and automated interpretation of EGM recordings in the near future.

Instant messaging (IM) enables medical professionals to quickly share clinical data to their peers for counselling. Purpose of this survey is to assess the habits related to IM, their application in clinical practice and the perceived pros and cons. An online survey was distributed to the medical community via newsletters, Twitter, LinkedIn, and Facebook. The survey consisted of 22 questions made on an individual-basis and collected anonymously on SurveyMonkey. A total of 287 subjects from 33 countries responded to the survey (mean age 43 years, 74.8% male). Of all respondents, 88.3% routinely send and 90.3% receive clinical data through IM which was second only to face-to-face contact as the preferred method for sharing clinical data. Twelve-lead electrocardiograms (88.6%), medical history (61.4%), and echo loops (55.7%) were the data shared most often. Nearly half of the clinical data that are sent (43%) or received (44%) are not anonymized. In the same way, 29.3% of the respondents were not aware of the European General Data Protection Regulation (GDPR) at the time of the survey. IM apps are used by medical professionals worldwide to share and discuss clinical data and are preferred to many other methods of data sharing, being second only to face-to-face contact. IM are often used to share many different types of clinical data, being perceived as a fast and easy way of communication. Medical professionals should be aware of the appropriate use of IM to prevent legal and privacy issues.

Data on reprocessing of electrophysiology (EP) materials are sparse. Reprocessing of catheters and other materials in daily routine varies through countries and may depend on specific material characteristics, supplier, or federal law. The aim of this study was to collect data on reprocessing usage through EHRA countries. An online survey consisting of 27 questions was distributed to EHRA Young EP members and members of national EP working groups. Two hundred and two participants from 34 EHRA countries completed the survey. One hundred and seven respondents (53.0%) reported having used and using reprocessed EP material, 30 (14.9%) respondents have used reprocessed EP material in the past but not at the time of the survey, 65 (32.2%) had never used reprocessed EP material. The most reprocessed EP materials include cables (70%), diagnostic EP catheters with deflectable (64%) or fixed curve (63%), non-irrigated ablation catheters (51%), and other conventional diagnostic catheters (41%). The most durable material was diagnostic EP catheters with a fixed curve (61%), the most sensitive material was ablation catheters with contact force sensors (21%). Important benefits were seen in reducing costs for the providing hospital (65%) and the healthcare provider (42%) and making EP procedures available for a greater number of patients (42%). Main concerns were on quality aspects (58%), contamination (52%), and loss of precision (47%). Reprocessing of EP materials is heterogeneously managed among EHRA countries. The present survey shows that European electrophysiologists consider the use of reprocessed EP material as generally safe and cost-effective.

Novel wearable devices for heart rhythm analysis using either photoplethysmography (PPG) or electrocardiogram (ECG) are in daily clinical practice. This survey aimed to assess impact of these technologies on physicians' clinical decision-making and to define, how data from these devices should be presented and integrated into clinical practice. The online survey included 22 questions, focusing on the diagnosis of atrial fibrillation (AF) based on wearable rhythm device recordings, suitable indications for wearable rhythm devices, data presentation and processing, reimbursement, and future perspectives. A total of 539 respondents {median age 38 [interquartile range (IQR) 34-46] years, 29% female} from 51 countries world-wide completed the survey. Whilst most respondents would diagnose AF (83%), fewer would initiate oral anticoagulation therapy based on a single-lead ECG tracing. Significantly fewer still (27%) would make the diagnosis based on PPG-based tracing. Wearable ECG technology is acceptable for the majority of respondents for screening, diagnostics, monitoring, and follow-up of arrhythmia patients, while respondents were more reluctant to use PPG technology for these indications. Most respondents (74%) would advocate systematic screening for AF using wearable rhythm devices, starting at patients' median age of 60 (IQR 50-65) years. Thirty-six percent of respondents stated that there is no reimbursement for diagnostics involving wearable rhythm devices in their countries. Most respondents (56.4%) believe that costs of wearable rhythm devices should be shared between patients and insurances. Wearable single- or multiple-lead ECG technology is accepted for multiple indications in current clinical practice and triggers AF diagnosis and treatment. The unmet needs that call for action are reimbursement plans and integration of wearable rhythm device data into patient's files and hospital information systems.

This European Heart Rhythm Association (EHRA) Scientific Initiatives Committee, EHRA Young Electrophysiologists, Association of Cardiovascular Nursing and Allied Professionals, and European Society of Cardiology (ESC) Council on Stroke joint survey aimed to assess the interpretation of the CHA2DS2-VASc score components and preferred resources for calculating the score. Of 439 respondents, most were general cardiologists (46.7%) or electrophysiologists (EPs) (42.1%). The overall adherence to the ESC-defined scoring criteria was good. Most variation was observed in the interpretation of the significance of left ventricular ejection fraction and brain natriuretic peptide in the scoring for the 'C' component, as well as the 'one-off high reading of blood pressure' to score on the 'H' component. Greater confidence was expressed in scoring the 'H' component (72.3%) compared with the 'C' (46.2%) and 'V' (45.9%) components. Respondents mainly relied on their recall for the scoring of CHA2DS2-VASc score (64.2%). The three most favoured referencing resources varied among different professionals, with pharmacists and physicians relying mainly on memory or web/mobile app, whereas nurses favoured using a web/mobile app followed by memory or guidelines/protocol. In conclusion, this survey revealed overall good adherence to the correct definition of each component in scoring of the 'C', 'H', and 'V' elements of the CHA2DS2-VASc score, although the variation in their interpretations warrants further clarifications. The preferred referencing resources to calculate the score varied among different healthcare professionals. Guideline education to healthcare professionals and updated and unified online/mobile scoring tools are suggested to improve the accuracy in scoring the CHA2DS2-VASc score.

The aim of this European Heart Rhythm Association (EHRA) survey was to assess the utilization of same-day discharge (SDD) in electrophysiology (EP). An online-based questionnaire was shared with the EHRA community between 12 and 30 June 2020 and recorded institutional information, complication assessment, recent experiences, and opinions regarding possible advantages or concerns with SDD. In total, 218 responses from 49 countries provided information on current SDD management. Overall, SDD was implemented in 77.5%, whereas this proportion was significantly higher in tertiary and high-volume centres (83.8% and 85.3%, both P < 0.01). The concept of SDD was most commonly used following implantations of cardiac event recorders (97%), diagnostic EP procedures (72.2%), and implantations of pacemakers with one or two intracardiac leads (50%), while the lowest SDD utilization was observed after catheter ablations of left atrial or ventricular arrhythmias. Within SDD-experienced centres, â¼90% respondents stated that this discharge concept is recommendable or highly recommendable and reported that rates of increased rehospitalization and complication rates were low. Most respondents assumed a better utilization of hospital resources (78.2%), better cost effectiveness (77.3%), and an improved patients' comfort but were concerned about possible impairment of detection (72.5%) and management (78.7%) of late complications. In conclusion, >75% of respondents already implement SDD following EP interventions with a large heterogeneity with regard to specific procedures. Further research is needed to confirm or disprove existing and expected benefits and obstacles.

BACKGROUND: The purpose of this study was to analyze electrophysiologists' radiation-protective devices for occupational exposure across European countries. METHODS: Data reported herein were gathered from the international, multicenter prospective Go for Zero Fluoroscopy registry performed in years 2018-2019. The registry encompassed 25 European electrophysiological centers from 14 countries and up to 5 operators from each center. RESULTS: The analysis included 95 operators (median age: 39 years, 85% of male, median training time: 5 years). The most frequently used X-ray protection tools (used by ≥80% of the group) were lead aprons, thyroid shields, screens below the table, glass in the laboratory, and least often (<7%) protective gloves and cabin. No statistically significant differences regarding the number of procedures performed monthly, electrophysiologists' experience and gender, and radiation exposure dose or radiation protection tools were observed, except lead thyroid shields and eyeglasses, which were more often used in case of fewer electrophysiological procedures performed (<20 procedures per month). Operators who were protected by >4 X-ray protection tools were exposed to lower radiation levels than those who were protected by ≤4 X-ray protection tools (median radiation exposure: 0.6 [0.2-1.1] vs. 0.2 [0.1-0.2] mSv per month, p < 0.0001; 1.1 [0.1-12.0] vs. 0.5 [0.1-1.1] mSv per year, p < 0.0001), respectively. CONCLUSIONS: Electrophysiologists' radiation-protective devices for occupational exposure are similar across European centers and in accordance with the applicable X-ray protection protocols, irrespective of the level of experience, number of monthly performed EP procedures, and gender.

AIMS: Atrial fibrillation (AF) catheter ablation is a common procedure requiring in most cases the use of fluoroscopy. We aimed to evaluate the factors associated with a lower dose of fluoroscopy used during AF ablation with cryoballoon or radiofrequency. METHODS: In this prospective European registry, centers were requested to provide procedural characteristics of consecutive AF ablation cases. Lower doses of fluoroscopy were defined as those with dose-area-product (DAP) under the median dose used in the radiofrequency and the cryoballoon ablation groups. RESULTS: A total of 638 AF ablation procedures were collected (n = 492 for radiofrequency and n = 146 for cryoballoon ablation groups) in 25 centers. The median [IQR] DAP were 926 [349;2092] and 1516 [418;3408] cGy*cm2 in the radiofrequency and cryoballoon groups, respectively. Main factors associated with lower DAP in cryoballoon ablation group were electrophysiology dedicated laboratory (OR 6.04, 95%CI 1.16-31.54; P = .03) and frequent dosimetry report (OR 21.39, 95%CI 5.43-98.54; P = .03). Main factors associated with lower DAP in the radiofrequency ablation group were the use of a chest dosimeter (OR 12.57, 95% CI 2.88-54.90; P = .01), biplane X-ray equipment (OR 3.12, 95%CI 1.89-5.16; P < .01), university hospital (OR 2.10, 95%CI 1.35-3.25; P = .01), electrophysiology dedicated laboratory (OR 2.45, 95%CI 1.48-4.05; P < .01) and use of contact force enabled catheter (OR 22.60, 95%CI 6.82-74.88; P < .01). CONCLUSION: This real-life study of fluoroscopy use during AF ablation provides new data about current practices across European countries. Technological advances and quality of the fluoroscopic environment were the main factors associated with lower radiation dose during AF ablation.

Autoimmune diseases (ADs) affect approximately 10% of the world's population. Because ADs are frequently systemic disorders, cardiac involvement is common. In this review we focus on typical arrhythmias and their pathogenesis, arrhythmia-associated mortality, and possible treatment options among selected ADs (sarcoidosis, systemic lupus erythematosus, scleroderma, type 1 diabetes, Graves' disease, rheumatoid arthritis, ankylosing spondylitis [AS], psoriasis, celiac disease [CD], and inflammatory bowel disease [IBD]). Rhythm disorders have different underlying pathophysiologies; myocardial inflammation and fibrosis seem to be the most important factors. Inflammatory processes and oxidative stress lead to cardiomyocyte necrosis, with subsequent electrical and structural remodeling. Furthermore, chronic inflammation is the pathophysiological basis linking AD to autonomic dysfunction, including sympathetic overactivation and a decline in parasympathetic function. Autoantibody-mediated inhibitory effects of cellular events (i.e., potassium or L-type calcium currents, M2muscarinic cholinergic or ß1-adrenergic receptor signaling) can also lead to cardiac arrhythmia. Drug-induced arrhythmias, caused, for example, by corticosteroids, methotrexate, chloroquine, are also observed among AD patients. The most common arrhythmia in most AD presentations is atrial arrhythmia (primarily atrial fibrillation), expect for sarcoidosis and scleroderma, which are characterized by a higher burden of ventricular arrhythmia. Arrhythmia-associated mortality is highest among patients with sarcoidosis and lowest among those with AS; there are scant data related to mortality in patients with psoriasis, CD, and IBD.

Catheter ablation (CA) is considered first-line treatment for many patients with symptomatic arrhythmias. Indications for CA are constantly increasing, as is the number of procedures. Although CA is nowadays regarded a safe procedure, there is a risk of complications, including both bleeding- and thrombosis-related events. Several factors contribute to periprocedural risk; of these, patient coagulation status is of considerable clinical relevance. In this context, even a simple procedure poses a considerable challenge in a patient with coagulation disorder. However, the level of evidence regarding CA in patients with coagulation disorders is very low. Neither experts' recommendations nor clinical guidelines have been presented so far. The aim of this article is to analyze potential procedure-related risks and provide clinicians with useful information and practical suggestions regarding optimization of procedural safety in patients with coagulation disorders.

INTRODUCTION: Periprocedural oral anticoagulation (OAC) strategies for atrial fibrillation (AF) ablation procedures are changing rapidly. OBJECTIVE: To assess the management and course of periprocedural OAC for AF ablation procedures in experienced electrophysiology (EP) centers in Germany over the last 12 months. METHODS: The data are based on an electronic questionnaire, which was sent to 35 experienced EP centers in September 2018 and then exactly 1 year later. Participants provided information on their periprocedural OAC management, the handling with dual therapy (OAC plus single antiplatelet therapy), the availability of specific antidotes, the transseptal puncture approach, and noteworthy complications. RESULTS: Responses were received from all 35 centers and represent 10,010 AF ablation procedures annually. In 2018, the administration of vitamin K antagonist (VKA) was continued throughout the procedure at all centers (100%). In contrast, the majority of centers used minimally interrupted periprocedural non-vitamin K antagonist oral anticoagulants (NOAC) (54.3%), 13 centers (37.2%) completely interrupted NOAC, and only 3 centers (8.5%) continued NOAC throughout the procedure. At the 1-year follow-up survey, 32 centers were found to have continued their previous strategy of periprocedural OAC and 3 changed from a minimally interrupted to a continued NOAC strategy. Of note, 30 centers (85.7%) performed transseptal puncture fluoroscopically without additional cardiac imaging. In the setting of uninterrupted periprocedural OAC management, no relevant complications were noted. CONCLUSION: Our survey shows marked heterogeneous periprocedural OAC management at experienced EP centers in Germany. Whereas continuation of VKA has already been integrated into clinical practice, the majority of centers still use a minimally interrupted NOAC strategy.

BACKGROUND: Since arrhythmia treatment in patients with autoimmune disease (AD) is challenging, we aimed to assess the common "real-world" practice in the electrophysiology centers. METHODS: Twenty-four young electrophysiologists being part of European Heart Rhythm Association filled questionnaire regarding arrhythmia management in AD. RESULTS: Rheumatoid arthritis was the most commonly reported AD accompanied by cardiac arrhythmias. The most frequent observed arrhythmias were atrial fibrillation and premature atrial/ventricular contractions. Most often electrocardiographic abnormalities observed were increased heart rate variability, QT interval prolongation, and P-wave dispersion, whereas echocardiographic abnormalities included left atrial enlargement, pericardial infusion, and left ventricular dysfunction. The most useful tool for arrhythmia management was guidelines and evidence-based medicine, while training courses and websites were at least useful. A close collaboration with other specialists in arrhythmia management was reported in 58.3% of respondents. Glucocorticoids and cytostatic were the most reported arrhythmia-induced drugs, whereas amiodarone and beta-blockers were most effective antiarrhythmic drugs. The main reason that discouraged respondents from cardiac implantable devices implantation and catheter ablation was high infection complications risk and recurrences during long-term follow-up, respectively. CONCLUSIONS: Scant data and guidelines enforce exchange of experience to improve the arrhythmia treatment in AD.

The advantages of upgrade to cardiac resynchronisation therapy (CRT) have not been explored as carefully as the outcomes of de novo CRT implantations. Furthermore selection criteria for patients with the potential to benefit the most from this therapy are unknown. Therefore, we analyzed the long term outcome and its predictors in a real-world cohort receiving a CRT upgrade from previous pacemaker (PM) and defibrillator devices (ICD). We analyzed 86 patients (mean age 68 ± 9 years; 89% male) undergoing CRT upgrade procedures. Response to CRT as well as long term patient outcome was analyzed. NYHA class improved in majority of the patients during short term period (61%), and this trend remained constant during long term follow-up (54%). The observed all-cause mortality was 54% with mean survival of 49 ± 4 months. 11 patients underwent left ventricular assist device implantation or heart transplantation. In the multivariate analysis, only kidney function assessed by GFR (HR 0.97; 95% CI 0.95-0.99; p = 0.009) and LVEF (HR 0.92; 95% CI 0.87-0.97; p = 0.002) remain predictors for mortality. Patients who undergo an upgrade procedure to CRT demonstrate a significant response rate assessed by improvement in NYHA class, with initial baseline parameters such as LVEF and kidney function remaining significant predictors for mortality.

BACKGROUND: The significance of the inducibility of atrial fibrillation (AF) after pulmonary vein isolation (PVI) in patients with AF remains disputable and polarizing. Therefore, we investigated the prognostic value of the inducibility of AF on long-term outcome after PVI in patients without low-voltage left atrial (LA) substrate. METHODS: Two hundred forty-five patients (mean age 59+/-9years, 72% male) without LA low-voltage areas (defined as electrogram amplitudes <0.5 mV) undergoing first PVI procedure were included in the study. Following successful PVI, inducibility was assessed by burst pacing from coronary sinus with a cycle length (CL) of 300, 250, and 200 ms or the shortest CL resulting in 1:1 atrial capture. During the follow-up period of up to 3 years, the rhythm outcome was monitored by serial 7-days Holter electrocardiogram. RESULTS: AF was induced in 38 patients (16%). Atypical atrial flutter was observed in six patients (2%), while typical flutter in three cases (1%). Within the first 3 months, early recurrence was diagnosed in 39 patients (16%), while late recurrence was detected in 58 patients (24%) after a mean AF free survival of 28 ± 1 months. While there was no impact on early recurrence, AF inducibility affected long-term recurrence (31 ± 1 vs 23 ± 3 months; P = .001). In multivariate analysis, AF inducibility (hazard ratio [HR] 2.14; 95% confidence interval [CI], 1.03-4.45; P = .041) and persistent type of AF (HR 2.17; 95%CI, 1.06-4.47; P = .034) were associated with late AF recurrence. CONCLUSION: In patients without low-voltage substrate undergoing PVI, AF inducibility is a significant predictor of long-term outcome. The pathomechanisms of this phenomenon must be further studied to be addressed by additional treatment.

Aims: Electrical cardioversion (ECV) is frequently required for early atrial fibrillation (AF) recurrence after catheter ablation. However, in some cases, ECV is unsuccessful, and factors associated with long-term rhythm outcomes after failed ECV are unknown. This study aimed to identify possible predictors of ECV failure early after AF ablation and to analyse management and long-term rhythm outcome of these patients. Methods and results: Between 2010 and 2012, 180 consecutive patients (mean age 63.7 ± 9.4 years, male 53.3%, persistent AF 60%) underwent successful radiofrequency AF ablation but required post-procedural ECV due to early AF recurrence (≤ 7 days). Of these, 120 patients were successful (Group A, n = 120, 66.7%) and 60 failed (Group B, n = 60, 33.3%). ECV failure was associated with diabetes [odds ratio (OR) 2.34, 95% confidence interval (CI) 1.154-4.763; P = 0.01] and lack of beta-blocker medication (OR 2.38, 95% CI 1.005-5.635; P = 0.04). In contrast, there were no significant differences in echocardiographic or procedure-related parameters. Atrial fibrillation recurrence was monitored with sequential 7 days of Holter electrocardiogram for 24 months (on average 10.8 ± 8.8 months) and was documented in 56%, n = 102 in total (Group A: 57%, n = 69 vs. Group B: 55%, n = 33; P = 0.75). Compared with successful ECV, ECV failure shortly after AF ablation had no predictive value on rhythm outcome in the long term (P = 0.98). The necessity of additional linear lesions during catheter ablation [hazard ratio (HR) 2.72, 95% CI 1.47-5.05; P = 0.001], AF duration (HR 1.08, 95% CI 1.04-1.12; P < 0.001), and a prolonged ablation time (HR 3.27, 95% CI 1.53-6.97; P = 0.002) were associated with long-term AF recurrence. Conclusion: Patients with diabetes and absence of beta-blocker medication are at higher risk for ECV failure. Early post-ablation ECV failure is not associated with long-term rhythm outcome.
