Management of patients with an electrical storm or clustered ventricular arrhythmias: a clinical consensus statement of the European Heart Rhythm Association of the ESC-endorsed by the Asia-Pacific Heart Rhythm Society, Heart Rhythm Society, and Latin-American Heart Rhythm Society.

Electrical storm (ES) is a state of electrical instability, manifesting as recurrent ventricular arrhythmias (VAs) over a short period of time (three or more episodes of sustained VA within 24 h, separated by at least 5 min, requiring termination by an intervention). The clinical presentation can vary, but ES is usually a cardiac emergency. Electrical storm mainly affects patients with structural or primary electrical heart disease, often with an implantable cardioverter-defibrillator (ICD). Management of ES requires a multi-faceted approach and the involvement of multi-disciplinary teams, but despite advanced treatment and often invasive procedures, it is associated with high morbidity and mortality. With an ageing population, longer survival of heart failure patients, and an increasing number of patients with ICD, the incidence of ES is expected to increase. This European Heart Rhythm Association clinical consensus statement focuses on pathophysiology, clinical presentation, diagnostic evaluation, and acute and long-term management of patients presenting with ES or clustered VA.

Predictors of ventricular tachyarrhythmia in patients with implantable cardioverter-defibrillator and non-ischemic systolic heart failure.

BACKGROUND: The benefit derived from implantable cardioverter-defibrillators (ICD) in subjects with non-ischemic systolic HF (NICM) is less well-established. AIM: The study aimed to determine the incidence, predictors, and prognostic impact of ventricular arrhythmias in patients with ICD and NICM. METHODS: The study sample included 377 consecutive patients with ICD or cardiac resynchronization cardioverter-defibrillators (CRT-D, 74% of patients) and NICM implanted and monitored remotely in a university hospital. RESULTS: During the median (interquartile range [IQR]) follow-up of 1645 (960-2675) days, sustained ventricular arrhythmia occurred in 92 patients (24.4%). Of those, ventricular fibrillation (VF), ventricular tachycardia (VT), and both VT and VF occurred in 10 (10.9%), 72 (78.3%), and 10 (10.9%) patients, respectively. Patients with vs. those without ventricular arrhythmia differed concerning sex, left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), left ventricular ejection fraction (LVEF), post-inflammatory etiology, atrial fibrillation/flutter occurrence, and supraventricular arrhythmia (SVT) other than AF/AFL during follow-up. In multivariable Cox regression, LVEDD (hazard ratio [HR], 1.05; 95% confidence interval [CI], 1.003-1.09; P = 0.03), AF/AFL (HR, 1.86; 95% CI, 1.21-2.85; P = 0.004), and SVT (HR, 1.77; 95% CI, 1.10-2.87; P = 0.02) were independent predictors of sustained VT, while AF/AFL (HR, 1.65; 95% CI, 1.07-2.56; P = 0.02) was independent predictor of VF. All-cause mortality in patients with VT/VF was significantly higher than in subjects without sustained ventricular arrhythmias (35.9% vs. 22.4%; P = 0.01). CONCLUSIONS: Ventricular arrhythmia occurred in every fourth patient with NICM and ICD during 4.5 years of observation and was associated with significantly worse prognosis than in subjects free of VT/VF. Higher LVEDD, atrial fibrillation/atrial flutter, and supraventricular tachycardia flag patients at risk of ventricular arrhythmia.

Poststroke Cardiovascular Management: Current Concepts, Integrated Care, and Future Developments.

After an ischemic stroke patients often have cardiovascular complications known as stroke-heart syndrome. The cardiovascular management after stroke has a significant impact on life expectancy as well as the quality of life. The development and implementation of management pathways to improve outcomes for patients with stroke-heart syndrome requires a multidisciplinary involvement from health care professionals from primary, secondary and tertiary prevention levels. A holistic, integrated care approach could follow the ABC pathway: A) Appropriate antithrombotic therapy in all stroke/TIA patients in the acute phase as well as recommendations for the longer term treatment regimen are required to avoid recurrent stroke. B) For better functional and psychological status the assessment of poststroke cognitive and physical impairment, depression, and anxiety as part of routine poststroke work-up in every patient is necessary. C) Cardiovascular risk factors and comorbidities management further includes cardiovascular work-up, adapted drug therapy, but often also lifestyle changes that are central to the success of integrated care for stroke-heart syndrome. Greater patient and family/caregiver involvement in planning actions and the input and feedback on optimizing stroke care pathways is needed. Achieving integrated care is challenging and highly context dependent on different healthcare levels. A tailored approach will utilize a variety of enabling factors. In this narrative review, we summarize the current evidence and outline potential factors that will contribute to the successful implementation of integrated cardiovascular care for stroke-heart syndrome management.

Lead-related tricuspid regurgitation and ventricle dysfunction: Current management and future perspectives.

The implantation of cardiac implantable electronic devices (CIEDs) may result in or worsen previously existing tricuspid regurgitation (TR). The prevelence of lead-related tricuspid regurgitation (LRTR) in patients with CIEDs is between 7.2% and 44.7% when the degree of worsening TR is not reported, or from 9.8% and 38% when it is diagnosed as worsening of TR severity by at least 2 grades after a CIED has been implanted. It has been suggested that a CIED lead positioned over or pinning a leaflet may be the main cause of TR in this patient population. The septal and posterior leaflets of the tricuspid valve have been reported to be the most affected by CIED leads. Severe LRTR is related to the development of heart failure (HF) or worsening of previously existing dysfunction; it is also associated with elevated mortality. However, there are no definitive predictors of LRTR development or standardized methods of treatment. Some studies have suggested that imaging-guided lead placement can reduce the occurrence of LRTR. This review summarizes current knowledge concerning the development, evaluation, consequences, and management of LRTR.

Patient selection, peri-procedural management, and ablation techniques for catheter ablation of atrial fibrillation: an EHRA survey.

Catheter ablation (CA) of atrial fibrillation (AF) is the therapy of choice for the maintenance of sinus rhythm in patients with symptomatic AF. Time towards interventional treatment and peri-procedural management of patients undergoing AF ablation may vary in daily practice. The scope of this European Heart Rhythm Association (EHRA) survey was to report the current clinical practice regarding the management of patients undergoing AF ablation and physician's adherence to the European Society of Cardiology Guidelines and the EHRA/HRS/ECAS expert consensus statement on the CA for AF. This physician-based survey was conducted among EHRA members, using an internet-based questionnaire developed by the EHRA Scientific Initiatives Committee. A total of 258 physicians participated in the survey. In patients with paroxysmal or persistent AF, 42 and 9% of the physicians would routinely perform AF ablation as first-line therapy respectively, whereas 71% of physicians would consider ablation as first-line therapy in patients with symptomatic AF and left ventricular ejection fraction <35%. Only 14% of the respondents manage cardiovascular risk factors in patients referred for CA using a dedicated AF risk factor management programme. Radiofrequency CA is the preferred technology for first-time AF (56%), followed by cryo-balloon CA (40%). This EHRA survey demonstrated a considerable variation in the management of patients undergoing AF ablation in routine practice and deviations between guideline recommendations and clinical practice.

Heart failure in patients with atrial fibrillation: Insights from Polish part of the EORP-AF general long-term registry.

AIMS: This study aimed to determine the impact of heart failure (HF) on clinical outcomes in patients with atrial fibrillation (AF). METHODS AND RESULTS: We analysed data from Polish participants of the EURObservational Research Programme-AF General Long-Term Registry. The primary endpoint was all-cause death, and the secondary endpoints included hospital readmissions, cardiovascular (CV) interventions, thromboembolic and haemorrhagic events, rhythm control interventions, and other CV or non-CV diseases development during one-year follow up. Overall, 688 patients with available data on HF were included into analysis; 51% (n = 351) had HF; of these 48% (n = 168) had reduced ejection fraction (HFrEF), 22% (n = 77) mid-range EF (HFmrEF), and 30% (n = 106) preserved EF (HFpEF). Compared with patients without HF, those with HF had higher mortality rate (aHR 5.61; 95% CI 1.94-16.22, P < 0.01). Patients with HF (vs. without HF) had more often CV interventions (10% vs. 5.4%, P = 0.046) and events (14% vs. 7.1%, P = 0.02), and had less often atrial arrhythmia-related hospital admissions (6.8% vs. 15%, P < 0.01). Over follow-up, patients with HFmrEF and HFpEF had similar mortality rate versus HFrEF (aHR 0.45, 95% CI 0.13-1.57, P = 0.45 for HFmrEF and aHR 0.54, 95% CI 0.20-1.48, P = 0.54 for HFpEF). Mortality rate was similar among rhythm versus rate control group (aHR 0.34; 95% CI 0.10-1.16; P = 0.34). CONCLUSIONS: AF patients with HF have greater mortality rate and more CV interventions/events. No statistically significant difference in long-term outcomes between patients with HFrEF, HFmrEF, and HFpEF highlights the need to develop therapeutic strategies targeting functional status and survival for patients with HF and AF.

Contemporary management of ventricular electrical storm in Europe: results of a European Heart Rhythm Association Survey.

Electrical storm (ES) is a predictor of mortality, and its treatment is challenging. Moreover, not all potential therapeutic strategies are available in all hospitals, and a standardized approach among European centres is lacking. The aim of this European Heart Rhythm Association (EHRA) survey was to assess the current management of patients with ES both in the acute and post-acute phases in 102 different European centres. A 20-item online questionnaire was sent out to the EHRA Research Network Centres. The median number of patients with ES treated annually per centre is 10 (IQR 5-15). The possibility of using autonomic modulation (e.g. percutaneous stellate ganglion block or thoracic epidural anaesthesia) for the acute ES treatment is available in only 29.3% of the centres. Moreover, although over 80% of centres perform ventricular tachycardia ablation, this procedure is available 24/7 in only 16.5% of the hospitals. There is a significant heterogeneity among centres regarding the availability of AADs and their use before deciding to proceed with a non-AAD strategy; specifically, 4.4% of centres use only one drug, 33.3% use two drugs, and 12.2% >two drugs, while about 50% of the centres decide based on individual patient's characteristics. Regarding the type of AADs used for the acute and post-acute management of ES patients, important variability is reported depending upon the underlying heart disease. Most patients considered for percutaneous ablation have structural heart disease. Only 46% of centres refer patients to psychological counselling after ES.

Integrated care for optimizing the management of stroke and associated heart disease: a position paper of the European Society of Cardiology Council on Stroke.

The management of patients with stroke is often multidisciplinary, involving various specialties and healthcare professionals. Given the common shared risk factors for stroke and cardiovascular disease, input may also be required from the cardiovascular teams, as well as patient caregivers and next-of-kin. Ultimately, the patient is central to all this, requiring a coordinated and uniform approach to the priorities of post-stroke management, which can be consistently implemented by different multidisciplinary healthcare professionals, as part of the patient 'journey' or 'patient pathway,' supported by appropriate education and tele-medicine approaches. All these aspects would ultimately aid delivery of care and improve patient (and caregiver) engagement and empowerment. Given the need to address the multidisciplinary approach to holistic or integrated care of patients with heart disease and stroke, the European Society of Cardiology Council on Stroke convened a Task Force, with the remit to propose a consensus on Integrated care management for optimizing the management of stroke and associated heart disease. The present position paper summarizes the available evidence and proposes consensus statements that may help to define evidence gaps and simple practical approaches to assist in everyday clinical practice. A post-stroke ABC pathway is proposed, as a more holistic approach to integrated stroke care, would include three pillars of management: A: Appropriate Antithrombotic therapy.B: Better functional and psychological status.C: Cardiovascular risk factors and Comorbidity optimization (including lifestyle changes).

Quality of life in patients with a subcutaneous vs. transvenous implantable cardioverter-defibrillator.

BACKGROUND: The implantable cardioverter-defibrillator (ICD) and subcutaneous ICD (S-ICD) are well-accepted life-saving devices for treating potentially lethal ventricular arrhythmia, but little is known about quality of life (QoL) in patients with S-ICD and ICD. AIMS: Our study aimed to compare QoL in patients with S-ICD and ICD. METHODS: All consecutive patients who had S-ICD implanted between October 2015 and September 2021 were included in the study. A cohort of transvenous ICD (TV-ICD) patients was matched to S-ICD subjects by sex, age, indications for the device, and type of prevention. All patients were requested to fulfill two standardized questionnaires to assess QoL: 36-Item Short Form Health Survey (SF-36) and Minnesota Living with Heart Failure Questionnaire (MLHFQ) 6 months after device implantation. RESULTS: Patients with S-ICD (n = 49) and TV-ICD (n = 49) did not differ regarding baseline characteristics. There were no statistically significant differences between S-ICD and TV-ICD subgroup, both for mental and physical QoL assessed in SF-36 and MLHFQ (all P = NS). The median MLHFQ total score was 24 (9-41) for S-ICD and 28 (14-43) for TV-ICD (P = 0.83). The median total score for the SF-36 questionnaire was 62.5 (29-86) vs. 59 (38-77) for S-ICD and TV-ICD, respectively (P = 0.78). CONCLUSIONS: Quality of life after device implantation does not differ significantly between the groups of patients with subcutaneous and conventional implantable cardioverter-defibrillator.

Radiofrequency catheter ablation as a treatment option in a patient with hypoplastic left heart syndrome and atrial flutter after Fontan operation-Case report.

We report a 15-year-old male with hypoplastic left heart syndrome (HLHS) after Fontan operation with recurrent, drug-resistant atrial tachycardia. With the use of electro-anatomical mapping system (EnSite) an atrial flutter (AFl) with reentry activation around the tricuspid valve was diagnosed. Successful radiofrequency catheter ablation (RFCA) was performed.

Utilization of Subcutaneous Cardioverter-Defibrillator in Poland and Europe-Comparison of the Results of Multi-Center Registries.

The implantation of a subcutaneous cardioverter-defibrillator (S-ICD) may be used instead of a traditional transvenous system to prevent sudden cardiac death. Our aim was to compare the characteristics of S-ICD patients from the multi-center registry of S-ICD implantations in Poland with the published results of the European Snapshot Survey on S-ICD Implantation (ESSS-SICDI). We compared data of 137 Polish S-ICD patients with 68 patients from the ESSS-SICDI registry. The groups did not differ significantly in terms of sex, prevalence of ischemic cardiomyopathy, concomitant diseases, and the rate of primary prevention indication. Polish patients had more advanced heart failure (New York Heart Association (NYHA) class III: 11.7% vs. 2.9%, NYHA II: 48.9% vs. 29.4%, NYHA I: 39.4% vs. 67.7%, p < 0.05 each). Young age (75.9% vs. 50%, p < 0.05) and no vascular access (7.3% vs. 0%, p < 0.05) were more often indications for S-ICD. The percentage of patients after transvenous system removal due to infections was significantly higher in the Polish group (11% vs. 1.5%, p < 0.05). In the European population, S-ICD was more frequently chosen because of patients' active lifestyle and patients' preference (both 10.3% vs. 0%, p < 0.05). Our analysis shows that in Poland, compared to other European countries, subcutaneous cardioverters-defibrillators are being implanted in patients at a more advanced stage of chronic heart failure. The most frequent reason for choosing a subcutaneous system instead of a transvenous ICD is the young age of a patient.

Clinical manifestations of device-related infective endocarditis in cardiac resynchronization therapy recipients.

INTRODUCTION: The aim of the study was to analyse microbiological characteristics and clinical manifestations of cardiac device-related infective endocarditis (CDRIE) in cardiac resynchronization therapy (CRT) recipients, and to compare the diagnostic value of modified Duke (MDC) versus modified Duke lead criteria (MDLC; including to MDC local infection and pulmonary infection or embolism as major criteria). MATERIAL AND METHODS: The study population comprised 765 consecutive CRT patients from a high-volume, tertiary care centre from 2002 to 2015. All patients were screened for CDRIE. RESULTS: During a median follow-up of 1692 days (range: 457-3067) 5.36% of patients (n = 41) developed CDRIE, which was accompanied by CRT pocket infection in 17.1% (n = 7) and recurrent pulmonary infection or pulmonary embolism in 29.3% (n = 12). Fever was present in 95.1% of patients (n = 39), whereas blood cultures were positive in 65.9% (n = 27). Staphylococcus was the most prevalent pathogen in 59.3% (n = 16), Gram-negative bacteria in 25.9% (n = 7). Transoesophageal echocardiography showed intracardiac vegetations in 73.2% of patients (n = 30). Non-different pathogen types with the most common methicillin-sensitive Staphylococcus aureus were observed for early versus late CDRIE (endocarditis ≤ 6 vs. > 6 months from CRT or other device-related procedure). All 3 inflammatory markers (C-reactive protein, white blood cells, procalcitonin) were normal in 4.9% of patients (n = 2). MDC versus MDLC indicated definite CDRIE in 48.8% versus 80.5%, respectively (p = 0.003). CONCLUSIONS: Fever is the most common symptom of CRT-related CDRIE, and transoesophageal echocardiography allows vegetations to be visualised in nearly 3/4 of patients with CDRIE. Although the most common pathogens were Staphylococci, Gram-negative bacteria accounted for a quarter of CDRIE. Modified Duke lead criteria proved superior to MDC.

Antithrombotic therapy for stroke prevention in patients with atrial fibrillation who survive an intracerebral haemorrhage: results of an EHRA survey.

The aim of this survey is to provide a snapshot of current practice regarding antithrombotic therapy (ATT) in patients with atrial fibrillation (AF) comorbid with intracerebral haemorrhage (ICH). An online survey was distributed to members of the European Heart Rhythm Association. A total of 163 clinicians responded, mostly cardiologists or electrophysiologists (87.7%), predominantly working in University hospitals (61.3%). Most respondents (47.2%) had seen one to five patients with AF comorbid with ICH in the last 12 months. Among patients sustaining an ICH on oral anticoagulation (OAC), 84.3% respondents would consider some form of ATT post-ICH, with 73.2% preferring to switch from a vitamin-K antagonist (VKA) to a non-VKA oral anticoagulant (NOAC) and 37.2% preferring to switch from one NOAC to another. Most (36.6%) would restart OAC >30 days post-ICH. Among patients considered unable to take OAC, left atrial appendage occlusion procedure was the therapy of choice in 73.3% respondents. When deciding on ATT, respondents considered patient's CHA2DS2-VASc score, ICH type, demographics, risk factors, and patient adherence. The main reason for not restarting or commencing ATT was concern about recurrent ICH (80.8%). National or international clinical guidelines would be advantageous to support decision-making (84.3%). Other helpful resources reported were multidisciplinary team involvement (46.9%) and patient education (82%). In summary, most survey respondents would prescribe OAC therapy for patients with AF who have sustained an ICH on OAC and would restart OAC >30 days post-ICH. The risk of recurrent ICH was the main reason for not prescribing any ATT post-ICH.

Current perspectives on wearable rhythm recordings for clinical decision-making: the wEHRAbles 2 survey.

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.
