BACKGROUND: Charcot-Marie-Tooth is the most common inherited neuromuscular disorder. Rarely, it can be associated with heart failure and various arrhythmic disturbances. This case illustrates the challenges of making decisions to prevent sudden cardiac death in a patient with Charcot-Marie-Tooth disease. CASE SUMMARY: A 69-year-old male with a history of Type 1A Charcot-Marie-Tooth disease was admitted due to repetitive runs of ventricular tachycardia. Twelve-lead electrocardiogram, echocardiography, selective coronary angiography, and cardiac magnetic resonance did not clarify the cause of the electrical storm. As conservative therapy was not successful, radiofrequency ablation was chosen to treat the electrical storm. After this procedure, implantable cardioverter defibrillator (ICD) was implanted. The follow-up revealed severe perforation by the ventricular lead. An extraction was performed with no complications and a new lead was immediately implanted. The patient remains asymptomatic. Three episodes of non-sustained ventricular tachycardia were recorded during the last follow-up. DISCUSSION: This case illustrates the challenges of making decisions to prevent sudden cardiac death in a patient with Charcot-Marie-Tooth disease after successful ablation for electrical storm. Due to a lack of evidence, atypical origin of arrhythmia, and clinical presentation, we did not consider this as idiopathic arrhythmia and decided to implant an ICD, which was complicated by severe perforation by the lead. Specific recommendations for preventing sudden cardiac death in rare cardiac conditions, such as Charcot-Marie-Tooth disease, still need to be refined.

BACKGROUND: To predict worsening heart failure hospitalizations (WHFHs), the HeartInsight multiparametric algorithm calculates a heart failure (HF) Score based on temporal trends of physiologic parameters obtained through automatic daily remote monitoring of implantable cardioverter-defibrillators (ICDs). OBJECTIVE: We studied the association of the baseline HF Score, determined at algorithm activation, with long-term patient outcomes. METHODS: Data from 9 clinical trials were pooled, including 1841 ICD patients with a preimplantation ejection fraction ≤35%, New York Heart Association class II/III, and no long-standing atrial fibrillation. The primary end point was a composite of death or WHFH. RESULTS: After a median follow-up of 631 days (interquartile range, 385-865 days), there were 243 WHFHs in 173 patients (9.4%) and 122 deaths (6.6%), 52 of which (42.6%) were cardiovascular. The primary end point occurred in 265 patients (14.4%). A multivariable time-to-first-event analysis showed that a high baseline HF Score (>23, as determined by a time-dependent receiver operating characteristics curve analysis) was significantly associated with the occurrence of the primary end point (adjusted hazard ratio [HR], 2.05; 95% confidence interval [CI], 1.54-2.71; P < .0001), all-cause death (HR, 2.37; CI, 1.56-3.58; P < .0001), cardiovascular death (HR, 2.19; CI, 1.14-4.22; P = .019), and WHFH (HR, 1.91; CI, 1.35-2.71; P = .0003). In a hierarchical event analysis of all-cause death as the outcome with highest priority and WHFHs as repeated event outcomes, the win ratio was 2.47 (CI, 1.89-3.24; P < .0001). CONCLUSION: Based on a retrospective analysis of clinical trial data with adjudicated events, baseline HF Score derived from device-monitored variables was able to stratify patients at higher long-term risk of death or WHFH.

AIMS: One treatment option for refractory ventricular arrythmias is stellate ganglion block (SGB). We examined differences in SGB success by patient and arrhythmia characteristics and predictors of successful SGB. METHODS AND RESULTS: This was a multicenter analysis of patients treated for refractory ventricular arrythmias in the Czech Republic and the United States. The primary outcome was absence of ventricular arrythmias at 24 h post SGB. SGB effectiveness was examined according to aetiology of cardiomyopathy, arrhythmia type, laterality of SGB, presence of inotropes, and presence of mechanical circulatory support. Binary logistic regression was used to examine variables associated with the primary outcome. In total there were 117 patients with refractory ventricular arrythmias treated with SGB. Overall, the mean age was 63.5 ± 11.0 years, majority of patients were male (94.0%), White (87.2%), and had an implantable cardioverter defibrillator in situ (70.1%). There were no differences in efficacy of SGB based on aetiology of cardiomyopathy (P = 0.623), arrhythmia type (0.852), laterality of block (P = 0.131), and presence of inotropes (P = 0.083). Multivariable analysis demonstrated that increased age was associated with decreased odds of SGB success (odds ratio: 0.96, confidence interval: 0.92-0.99, P = 0.039) whereas increased left ventricular ejection fraction trended towards increased odds of SGB success (odds ratio: 1.05, confidence interval: 0.995-1.11, P = 0.077). CONCLUSIONS: In this multicentre experience, SGB was similarly effective despite the aetiology of cardiomyopathy, type of arrhythmia, laterality, and inotropic or mechanical support. SGB was less effective for the suppression of ventricular arrythmias at 24 h for the elderly.

Izolovaná srdeční sarkoidóza je vzácné onemocnění, které je často obtížně detekovatelné vzhledem k nízké senzitivitě endomyokardiální biopsie (EMB), a proto obvykle vyžaduje multimodální vyšetření pomocí magnetické rezonance srdce (CMR) a/nebo pozitronové emisní tomografie – výpočetní tomografie (PET-CT) s aplikací 18F fl uordeoxyglukózy (FDG). Klinická manifestace onemocnění zahrnuje pokročilou atrioventrikulární blokádu, maligní komorové arytmie a městnavé srdeční selhání. Cílem práce je ukázat úskalí při diagnostice klinicky izolované sarkoidózy srdce u mladého muže po resuscitaci pro maligní komorovou arytmii. V kontextu tohoto případu poskytneme přehled současných znalostí managementu srdeční sarkoidózy. Popis případu: Osmadvacetiletý muž bez významnějších přidružených onemocnění byl přijat na naše pracoviště po krátké resuscitaci pro mimonemocniční zástavu oběhu při fi brilaci komor v únoru 2022. Na vstupním EKG byl přítomen sinusový rytmus s kompletní atrioventrikulární blokádou a morfologií komplexu QRS charakteru blokády levého Tawarova raménka. Následně byla dokumentována těžká neischemická systolická dysfunkce nedilatované levé komory s ejekční frakcí 25 %. EMB ukázala pouze nespecifický nález. Pro přetrvávající atrioventrikulární blokádu III. stupně byl pacientovi implantován kardioverter-defibrilátor s možností biventrikulární stimulace. Magnetickou rezonanci srdce jsme neindikovali z bezpečnostních důvodů u pacienta dependentního na kardiostimulaci a také jsme očekávali horší kvalitu vyšetření při artefaktech z implantovaných elektrod. V březnu 2022 bylo provedeno PET-CT s aplikací FDG, nicméně nález na srdci byl nediagnostický vzhledem k nedostatečné supresi metabolismu cukrů. Byly však zastiženy tři avidní uzliny v mediastinu. Pro trvající podezření na srdeční sarkoidózu bylo provedeno kontrolní PET-CT v červenci 2022, kdy se již zdařila suprese metabolismu glukózy v myokardu. Byl dokumentován nepoměr mezi fokálně zvýšenou akumulací FDG v oblasti anteroapikální, septální a bazální a výpadkem perfuze, který je charakteristický pro pokročilejší stadia zánětlivých srdečních onemocnění. Současně byla zaznamenána progrese lymfadenopatie na obou stranách bránice. Bronchoskopie a transbronchiální biopsie přinesly negativní nález. Opakovaná EMB verifi kovala sarkoidózu myokardu. V době první manifestace onemocnění se tedy jednalo o klinicky izolovanou srdeční sarkoidózu. Na základě tohoto nálezu byla zahájena imunosupresivní léčba kortikoidy a azathioprinem, kterou pacient toleroval bez komplikací. Postupně došlo ke zlepšení ejekční frakce levé komory, která v září 2023 dosáhla 45 %. Pacient zůstává během sledování klinicky stabilní ve funkční třídě II, bez intervencí přístroje pro komorové tachykardie. Od března 2023 přestal být pacient dependentní na kardiostimulaci. Závěr: Na diagnózu srdeční sarkoidózy je třeba myslet u pacientů s neischemickou dysfunkcí levé komory, zvláště v přítomnosti aneurysmat levé nebo pravé komory. Podezření zvyšuje přítomnost pokročilejší atrio- ventrikulární blokády nebo výskyt maligních komorových arytmií. Diagnostika je zvláště obtížná u izolované srdeční sarkoidózy, kde je obvykle nutno aplikovat kombinaci zobrazovacích metod, včetně CMR a PET-CT, případně opakovat EMB k dosažení správné diagnózy. Ta je důležitá jak z prognostických, tak i terapeutických důvodů.

Isolated cardiac sarcoidosis is a rare disease with a challenging diagnostic process reflecting a low sensitivity of endomyocardial biopsy (EMB). Therefore, it often requires a multimodal imaging using cardiac magnetic resonance imaging (CMR) and/or positron emission tomography (PET-CT) with administration of 18Ffluordeoxyglucose (FDG). Its clinical manifestation includes advanced atrioventricular block, ventricular tachyar- rhythmias and congestive heart failure. We aimed to illustrate pitfalls in the diagnosis of clinically isolated cardiac sarcoidosis in a young male with an aborted cardiac arrest due to ventricular fibrillation. This case inspired us to provide an updated review of the management of cardiac sarcoidosis. Case description: A 28-year-old male without any comorbidities was admitted to our department after an aborted out-of-hospital cardiac arrest due to ventricular fibrillation in February 2022. His first electrocardiogram showed sinus rhythm and a complete atrioventricular block with left bundle branch block QRS morphology. Echocardiogram and coronary angiography revealed severe non-ischemic systolic dysfunction of the non-dilated left ventricle with an ejection fraction of 25%. Findings in EMB specimens were non-specific. A biventricular cardioverter-defibrillator was implanted due to a persistent complete atrioventricular block. Cardiac magnetic resonance imaging was not done from the safety reasons due to dependency of the subject on cardiac pacing and expected poor quality due to artefacts from the implanted electrodes. In March 2022, PET-CT with administration of FDG was performed. Unfortunately, the examination was not diagnostic due to an incomplete suppression of the metabolism of carbohydrates. However, three avid lymphatic nodes were detected in mediastinum. Repeated PET-CT was performed in July 2022 with successful suppression of the metabolism of carbohydrates. The examination revealed a mismatch between focally increased accumulation of FDG and absent perfusion in anteroapical, septal, and basal segments, which is a typical finding for an inflammatory cardiac disease. In addition, there was an obvious progression of lymphadenopathy both above and under the diaphragm. Subsequently, we performed a repeated EMB, which verified cardiac sarcoidosis. This suggested a diagnosis of isolated cardiac sarcoidosis at the time of disease manifestation. These results enabled to start immunosuppression with corticosteroids and azathioprine, which was tolerated without complications. A gradual improvement in left ventricular ejection fraction up to 45% was observed and documented in September 2023. The patient remains clinically stable in the functional class II, without interventions from the implanted cardioverter-defibrillator. Since March 2023, the patient is not dependent on cardiac pacing. Conclusion: The diagnosis of cardiac sarcoidosis should be considered in patients with non-ischemic dysfunction of the left ventricle, especially if accompanied with aneurysms of cardiac ventricles. The suspicion rises in the presence of atrioventricular blocks or occurrence of ventricular tachyarrhythmias. The difficult diagnosis of isolated cardiac sarcoidosis can be established in selected cases by multimodal imaging including CMR and PET-CT, or repeate

BACKGROUND: The TREAT-NMD Global Registry Network is a global collaboration of neuromuscular disease registries, including myotonic dystrophy type 2 (DM2), which aims to facilitate collaborative research and clinical trials. OBJECTIVES: This study aimed to assess DM2 patients included in the network, and to analyse their socio-demographic and clinical features. METHODS: Data were collected through email surveys sent to 16 TREAT-NMD myotonic dystrophy core member registries. 10 registries enrolled DM2 patients. RESULTS: The total number of DM2 cases was 1,720, with the Czech, German, and USA registries enrolling the most patients (445, 430, and 339 cases, respectively). The highest rates were seen in Czechia and Serbia (4.2 and 2.0 registered per 100,000 population, respectively). High DM2:DM1 ratios were seen in Central Europe. The median age at registry entry was 51 years. Symptom onset occurred before age 20 in 14% of cases. One fifth of patients used an assistive device to walk, and 4% were non-ambulatory. Insertion of a pacemaker or implantable cardioverter-defibrillator was reported in 4% of subjects, while 7% used non-invasive ventilation. CONCLUSIONS: This represents the largest DM2 cohort assembled to date, providing demographic and clinical data for future research and trial recruitment, illustrating TREAT-NMD's international reach and the importance of capturing DM2 data.

BACKGROUND: Inappropriate therapy (IAT) is an undesirable side effect of implantable cardiac defibrillator (ICD) therapy. Early studies with the subcutaneous ICD (S-ICD) showed relatively high inappropriate shock (IAS) rates. The PRAETORIAN (Prospective Randomized Comparison of Subcutaneous and Transvenous Implantable Cardioverter Defibrillator Therapy) trial demonstrated that the S-ICD is noninferior to the transvenous ICD (TV-ICD) with regard to the combined end point of IAS and complications. This secondary analyses evaluates all IAT in the PRAETORIAN trial. METHODS: This international, multicenter trial randomized 849 patients with an indication for ICD therapy between S-ICD (n=426) and TV-ICD therapy (n=423). ICD programming was mandated by protocol. All analysis were performed in the modified intention-to-treat population. RESULTS: In both groups 42 patients experienced IAT (48-month Kaplan-Meier estimated cumulative incidence, 9.9% and 10.1%, respectively; hazard ratio (HR), 0.99 [95% CI, 0.65-1.52]; P=0.97). There was no significant difference in patients experiencing IAS between both groups (P=0.14). In the S-ICD group, 81 IAT episodes with 124 IAS and 1 inappropriate antitachycardia pacing occurred versus 89 IAT episodes with 130 IAS and 124 inappropriate antitachycardia pacing in the TV-ICD group. IAT episodes were most frequently caused by supraventricular tachycardias in the TV-ICD group (n=83/89) versus cardiac oversensing in the S-ICD group (n=40/81). In the TV-ICD group, a baseline heart rate >80 bpm (HR, 1.99 [95% CI, 1.05-3.76]; P=0.03), a history of atrial fibrillation (HR, 2.66 [95% CI, 1.41-5.02]; P=0.003), and smoking (HR, 2.46 [95% CI, 1.31-4.09]; P=0.005) were independent predictors for IAT. A QRS duration >120 ms was an independent predictor for IAT caused by cardiac oversensing in the S-ICD group (HR, 3.13 [95% CI, 1.34-7.31]; P=0.008). Post-IAS interventions significantly reduced IAS recurrence in both groups (P=0.046). CONCLUSIONS: There was no significant difference in IAT and IAS rates between the S-ICD and TV-ICD in a conventional ICD population, but causes and predictors for IAT differed between the devices. After the first IAS, an intervention significantly reduced the recurrence rate of IAS. REGISTRATION: URL: https://www.clinicaltrials.gov; Unique identifier: NCT01296022.

BACKGROUND: The subcutaneous implantable cardioverter-defibrillator (S-ICD) was developed to overcome the risk of lead-related complications associated with the transvenous implantable cardioverter-defibrillator (TV-ICD). In contrast to the TV-ICD, the S-ICD is a completely extrathoracic device. Subsequently, complications differ between these 2 implantable cardioverter-defibrillators, which might impact patient perceptions of the therapies. This prespecified secondary analysis of the PRAETORIAN trial evaluates differences in quality of life. METHODS: The PRAETORIAN trial (A Prospective, Randomized Comparison of Subcutaneous and Transvenous Implantable Cardioverter Defibrillator Therapy) randomized patients with an implantable cardioverter-defibrillator indication, without the need for pacing to S-ICD or TV-ICD therapy. Two questionnaires were collected at baseline, discharge, 12 months, and 30 months. The Duke Activity Status Index measures cardiac-specific physical functioning, and the 36-Item Short Form Health Survey measures physical and mental well-being, with the subscales bodily pain and mental health being of interest in this analysis. Mann-Whitney U tests were used to compare study arms, and a mixed model was used to describe the questionnaire outcomes over time. RESULTS: Patients were randomized to S-ICD (n=426) and TV-ICD (n=423). In the S-ICD group, 20% were women versus 19% in the TV-ICD group. The median age was 63 (interquartile range, 54-69) years in the S-ICD group versus 64 (interquartile range, 56-69) years in the TV-ICD group. There were no significant differences in the Duke Activity Status Index and 36-Item Short Form Health Survey subscales for bodily pain and mental health between the groups at any time point. Patients with a shock in the last 90 days had significantly lower scores for social functioning (P=0.008) and role limitations due to emotional problems (P=0.001) than patients without a shock, but this effect did not differ between treatment arms. CONCLUSIONS: In a large randomized cohort of patients with an S-ICD or TV-ICD, no difference in overall quality of life was observed. However, implantable cardioverter-defibrillator shocks resulted in a reduction in quality of life, regardless of the device type or appropriateness.

BACKGROUND AND AIMS: Risk stratification of sudden cardiac death after myocardial infarction and prevention by defibrillator rely on left ventricular ejection fraction (LVEF). Improved risk stratification across the whole LVEF range is required for decision-making on defibrillator implantation. METHODS: The analysis pooled 20 data sets with 140 204 post-myocardial infarction patients containing information on demographics, medical history, clinical characteristics, biomarkers, electrocardiography, echocardiography, and cardiac magnetic resonance imaging. Separate analyses were performed in patients (i) carrying a primary prevention cardioverter-defibrillator with LVEF ≤ 35% [implantable cardioverter-defibrillator (ICD) patients], (ii) without cardioverter-defibrillator with LVEF ≤ 35% (non-ICD patients ≤ 35%), and (iii) without cardioverter-defibrillator with LVEF > 35% (non-ICD patients >35%). Primary outcome was sudden cardiac death or, in defibrillator carriers, appropriate defibrillator therapy. Using a competing risk framework and systematic internal-external cross-validation, a model using LVEF only, a multivariable flexible parametric survival model, and a multivariable random forest survival model were developed and externally validated. Predictive performance was assessed by random effect meta-analysis. RESULTS: There were 1326 primary outcomes in 7543 ICD patients, 1193 in 25 058 non-ICD patients ≤35%, and 1567 in 107 603 non-ICD patients >35% during mean follow-up of 30.0, 46.5, and 57.6 months, respectively. In these three subgroups, LVEF poorly predicted sudden cardiac death (c-statistics between 0.50 and 0.56). Considering additional parameters did not improve calibration and discrimination, and model generalizability was poor. CONCLUSIONS: More accurate risk stratification for sudden cardiac death and identification of low-risk individuals with severely reduced LVEF or of high-risk individuals with preserved LVEF was not feasible, neither using LVEF nor using other predictors.

Left ventricular assist devices (LVADs) are an increasingly used strategy for the management of patients with advanced heart failure. Although these devices effectively improve survival, atrial and ventricular arrhythmias are common with a prevalence of 20-50% at one year after LVAD implantation. Arrhythmias predispose these patients to additional risk and are associated with considerable morbidity from recurrent implantable cardioverter-defibrillator shocks, progressive failure of the unsupported right ventricle, and herald an increased risk of mortality. Management of patients with arrhythmias and LVAD differs in many aspects from the general population heart failure patients. These include ruling out the reversible causes of arrhythmias that in LVAD patients may include mechanical irritation from the inflow cannula and suction events. For patients with symptomatic arrhythmias refractory to medical treatment, catheter ablation might be relevant. There are specific technical and procedural challenges perceived to be unique to LVAD-related ventricular tachycardia (VT) ablation such as vascular and LV access, signal filtering, catheter manoeuvrability within decompressed chambers, and electroanatomic mapping system interference. In some patients, the arrhythmogenic substrate might not be readily accessible by catheter ablation after LVAD implantation. In this regard, the peri-implantation period offers a unique opportunity to surgically address arrhythmogenic substrate and suppress future VT recurrences. This document aims to address specific aspects of the management of arrhythmias in LVAD patients focusing on anti-arrhythmic drug therapy and ablations.

Hypertrofická kardiomyopatie je geneticky podmíněné onemocnění charakterizované zesílením stěn myokardu levé komory nad 15 mm při absenci jiné vysvětlující příčiny. Součástí diagnostiky a léčby pacientů s hypertrofickou kardiomyopatií je pátrání po obstrukci ve výtokovém traktu levé komory a její management, stratifikace rizika náhlé srdeční smrti, provedení genetického testování a screening rodinných pří- slušníků. Kazuistika popisuje případ mladého muže s chronickým dermatologickým onemocněním na trvalé biologické léčbě, s pozitivní rodinnou anamnézou náhlé srdeční smrti, u něhož byla nově diagnostikována hypertrofická kardiomyopatie se symptomatickou obstrukcí ve výtokovém traktu levé komory. U pacienta bylo indikováno provedení alkoholové septální ablace, která měla dobrý hemodynamický i klinický výsledek. V primární prevenci náhlé srdeční smrti mu byl implantován implantabilní kardioverter-defibrilátor, došlo však ke komplikaci v podobě časné infekce kapsy přístroje při pacientově kožním onemocnění a rozvoji reaktivní perikarditidy.

Hypertrophic cardiomyopathy is a genetic disorder characterized by increased left ventricle thickness greater than 15 milimetres in the absence of any other explanatory cause. The diagnostics and treatment of patients with hypertrophic cardiomyopathy include search for a management of left ventricular outflow tract obstruction, risk stratification for sudden cardiac death and genetic testing and screening of family members. This case report describes a young man with a chronic skin disease on permanent biological therapy who had a family history of sudden cardiac death and had recently been diagnosed with hypertrophic cardiomyopathy with symptomatic left ventricular outflow tract obstruction. An alcohol septal ablation had been indicated, resulting in improved hemodynamic and clinical outcome. An implantable cardioverter-defibrillator was implanted for the primary prevention of sudden cardiac death. However, an early device pocket infection due to the patient's skin disease and the development of reactive pericarditis led to complications.
