RESUMEN
BACKGROUND: Patients with atrial fibrillation (AF) and intracerebral hemorrhage (ICH) are at high risk of ischemic and recurrent bleeding events. Therefore, the decision of restarting or avoiding anticoagulation is challenging. Left atrial appendage occlusion (LAAO) is an alternative for these patients. However, few data are available about safety of early LAAO and factors associated with ischemic stroke and ICH recurrence. METHODS: A unicentric, observational, retrospective study including all patients with AF and a previous ICH who underwent LAAO. We analyzed baseline clinical and neuroimaging characteristics, procedural outcomes, post-procedural therapies and long-term follow-up. RESULTS: Forty patients were included, whose mean age was 76.6 ±7.6 years and 73 % were men. In patients in whom a Magnetic Resonance (MR) was performed (n=22, 55 %), cortical microbleeds were detected in 15 (68 %) and cortical superficial siderosis in one patient. The procedure was successful and safe in 100 % of the patients and it was performed within 30 days of the ICH in 37 % of them. After a median follow up of 46.2 months [26-69], intracranial hemorrhage (ICrH) recurrence occurred in 6 patients (5 ICH and 1 subdural hematoma -SDH-) and the index ICH was lobar in all of them. Ischemic events were significantly lower than expected according to the CHA2DS2-VASc score (7.5 % vs. 16.6 %, p=0.048) and bleeding events were similar to expected by the HAS-BLED score (20 % vs 23.4 %, p=0.63). CONCLUSIONS: In patients with ICH and AF, early LAAO was found to be safe and associated with a reduction in ischemic stroke. However, recurrent ICH risk remains high, and it appears to be mainly driven by cerebral amyloid angiopathy.

BACKGROUND: Desmin (DES) pathogenic variants cause a small proportion of arrhythmogenic cardiomyopathy (ACM). Outcomes data on DES-related ACM are scarce. OBJECTIVES: This study sought to provide information on the clinical phenotype and outcomes of patients with ACM caused by pathogenic variants of the DES gene in a multicenter cohort. METHODS: We collected phenotypic and outcomes data from 16 families with DES-related ACM from 10 European centers. We assessed in vitro DES aggregates. Major cardiac events were compared to historical controls with lamin A/C truncating variant (LMNA-tv) and filament C truncating variant (FLNC-tv) ACM. RESULTS: Of 82 patients (54% males, median age: 36 years), 11 experienced sudden cardiac death (SCD) (n = 7) or heart failure death (HFd)/heart transplantation (HTx) (n = 4) before clinical evaluation. Among 68 survivors, 59 (86%) presented signs of cardiomyopathy, with left ventricular (LV) dominant (50%) or biventricular (34%) disease. Mean LV ejection fraction was 51% ± 13%; 36 of 53 had late gadolinium enhancement (ring-like pattern in 49%). During a median of 6.73 years (Q1-Q3: 3.55-9.52 years), the composite endpoint (sustained ventricular tachycardia, aborted SCD, implantable cardioverter-defibrillator therapy, SCD, HFd, and HTx) was achieved in 15 additional patients with HFd/HTx (n = 5) and SCD/aborted SCD/implantable cardioverter-defibrillator therapy/sustained ventricular tachycardia (n = 10). Male sex (P = 0.004), nonsustained ventricular tachycardia (P = 0.017) and LV ejection fraction ≤50% (P = 0.012) were associated with the composite endpoint. Males with DES variants had similar outcomes to historical FLNC-tv and LMNA-tv controls. However, females showed better outcomes than those with LMNA-tv. In vitro experiments showed the characteristic finding of DES aggregates in 7 of 12 variants. CONCLUSIONS: DES ACM is associated with poor outcomes which can be predicted with potentially successful treatments, underscoring the importance of familial evaluation and genetic studies to identify at risk individuals.

INTRODUCTION AND OBJECTIVES: Repetitive ambulatory doses of levosimendan are an option as a bridge to heart transplantation (HT), but evidence regarding the safety and efficacy of this treatment is scarce. The objective of the LEVO-T Registry is to describe the profile of patients on the HT list receiving levosimendan, prescription patterns, and clinical outcomes compared with patients not on levosimendan. METHODS: We retrospectively reviewed all patients listed for elective HT from 2015 to 2020 from 14 centers in Spain. RESULTS: A total of 1015 consecutive patients were included, of whom 238 patients (23.4%) received levosimendan. Patients treated with levosimendan had more heart failure (HF) admissions in the previous year and a worse clinical profile. The most frequent prescription pattern were fixed doses triggered by the patients' clinical needs. Nonfatal ventricular arrhythmias occurred in 2 patients (0.8%). No differences in HF hospitalizations were found between patients who started levosimendan in the first 30 days after listing and those who did not (33.6% vs 34.5%; P=.848). Among those who did not, 102 patients (32.9%) crossed over to levosimendan after an HF admission. These patients had a rate of 0.57 HF admissions per month before starting levosimendan and 0.21 afterwards. Propensity score matching analysis showed no differences in survival at 1 year after listing between patients receiving levosimendan and those who did not (HR, 1.03; 95%CI, 0.36-2.97; P=.958) or in survival after HT (HR, 0.97; 95%CI, 0.60-1.56; P=.958). CONCLUSIONS: Repetitive levosimendan in an ambulatory setting as a bridge to heart transplantation is commonly used, is safe, and may reduce HF hospitalizations.

Background: Myocarditis is an infrequent extrapulmonary manifestation of tuberculosis that confers an unfavourable prognosis. Case summary: A 36-year-old man presented to the hospital with palpitations and dyspnoea. Tests revealed the presence of non-sustained ventricular tachycardia, with mild elevation of troponin and C-reactive protein levels. Coronary angiography showed normal results. A cardiac magnetic resonance (CMR) showed moderate hypertrophy, preserved ejection fraction, and an extensive multi-segmental pattern of fibrosis and oedema. An 18F-fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDG-PET-CT) scan revealed multiple hypermetabolic adenopathies and patchy cardiac uptake. A tuberculin skin test and interferon-gamma release assay were both positive. An endomyocardial biopsy (EMB) showed inflammation without granulomas; and microbiological stains were negative. Biopsy of an adenopathy revealed the presence of multiple necrotizing granulomas with Langhans cells. Based on the test results and clinical presentation, the suspected diagnosis was tuberculous myocarditis. Treatment with anti-tuberculosis drugs was started. One month later, the presence of mycobacterium tuberculosis (MT) was detected in the lymph node culture. At 7 months of follow-up, the patient remains asymptomatic, ventricular arrhythmias have ceased, and radiological signs of inflammation have resolved. Discussion: Ventricular arrhythmia is one of the clinical manifestations of tuberculous myocarditis. Cardiac magnetic resonance and 18F-FDG-PET-CT imaging are an essential component of the non-invasive evaluation of inflammatory cardiomyopathy. However, a confirmatory biopsy may be required to identify potentially treatable aetiologies. Although the diagnosis of tuberculous myocarditis requires an isolation of MT by staining or culture in EMB, the diagnostic yield is very low. For this reason, extra-cardiac findings may provide the definitive diagnostic clue.
RESUMEN
AIM: Patients with advanced heart failure (AHF) who are not candidates to advanced therapies have poor prognosis. Some trials have shown that intermittent levosimendan can reduce HF hospitalizations in AHF in the short term. In this real-life registry, we describe the patterns of use, safety and factors related to the response to intermittent levosimendan infusions in AHF patients not candidates to advanced therapies. METHODS AND RESULTS: Multicentre retrospective study of patients diagnosed with advanced heart failure, not HT or LVAD candidates. Patients needed to be on the optimal medical therapy according to their treating physician. Patients with de novo heart failure or who underwent any procedure that could improve prognosis were not included in the registry. Four hundred three patients were included; 77.9% needed at least one admission the year before levosimendan was first administered because of heart failure. Death rate at 1 year was 26.8% and median survival was 24.7 [95% CI: 20.4-26.9] months, and 43.7% of patients fulfilled the criteria for being considered a responder lo levosimendan (no death, heart failure admission or unplanned HF visit at 1 year after first levosimendan administration). Compared with the year before there was a significant reduction in HF admissions (38.7% vs. 77.9%; P < 0.0001), unplanned HF visits (22.7% vs. 43.7%; P < 0.0001) or the combined event including deaths (56.3% vs. 81.4%; P < 0.0001) during the year after. We created a score that helps predicting the responder status at 1 year after levosimendan, resulting in a score summatory of five variables: TEER (+2), treatment with beta-blockers (+1.5), Haemoglobin >12 g/dL (+1.5), amiodarone use (-1.5) HF visit 1 year before levosimendan (-1.5) and heart rate >70 b.p.m. (-2). Patients with a score less than -1 had a very low probability of response (21.5% free of death or HF event at 1 year) meanwhile those with a score over 1.5 had the better chance of response (68.4% free of death or HF event at 1 year). LEVO-D score performed well in the ROC analysis. CONCLUSION: In this large real-life series of AHF patients treated with levosimendan as destination therapy, we show a significant decrease of heart failure events during the year after the first administration. The simple LEVO-D Score could be of help when deciding about futile therapy in this population.

Introducción y objetivos:El levosimendán ambulatorio repetitivo es una opción como puente al trasplante cardiaco (TxC), aunque la evidencia sobre su eficacia y su seguridad es escasa. El objetivo del registro LEVO-T es describir a los pacientes en lista de TxC que reciben levosimendán, sus pautas y los eventos clínicos durante el seguimiento, en comparación con los que no lo reciben. Métodos: Se revisó en retrospectiva a los pacientes en lista de espera para TxC electivo de 14 centros españoles desde 2015 hasta 2020. Resultados: Se incluyó a 1.015 pacientes consecutivos; los 238 (23,4%) que recibieron levosimendán mostraron más ingresos por insuficiencia cardiaca (IC) el año anterior y peor perfil clínico. Las dosis fijas por necesidades clínicas fueron la pauta más frecuente. Dos pacientes (0,8%) presentaron arritmias ventriculares no mortales. No hubo diferencias en hospitalizaciones por IC entre los que comenzaron levosimendán en los primeros 30 días después de inclusión y los que no (el 33,6 frente al 34,5%; p=0,848). De estos últimos, 102 (32,9%) pasaron a levosimendán después de un ingreso por IC, y la tasa de ingresos por IC/mes varió de 0,57 antes del levosimendán a 0,21 después. El análisis mediante emparejamiento por puntuación de propensión no mostró diferencias entre los pacientes con y sin levosimendán en la supervivencia a 1 año tras la inclusión en lista (HR=1,03; IC95%, 0,36-2,97; p=0,958) ni en la supervivencia tras el TxC (HR=0,97; IC95%, 0,60-1,56; p=0,958). Conclusiones: El levosimendán ambulatorio repetitivo como puente al trasplante cardiaco es un tratamiento frecuente y seguro que podría reducir ingresos por IC. (AU)
