Prevalence of neurological complications in infective endocarditis.

INTRODUCTION: Neurological complications are the most frequent type of extracardiac complications of infective endocarditis (IE), and can be the initial manifestation. The objectives of this study were to determine the prevalence of neurological complications in patients with IE and to evaluate whether initial presentation with neurological symptoms causes a diagnostic delay. MATERIAL AND METHODS: We conducted a retrospective observational study of patients with IE admitted to a tertiary hospital between 2003 and 2020. RESULTS: The study included 222 patients with IE (67% men; mean [SD] age, 66.4 [14.2] years). Neurological complications occurred in 21.2% of patients, with ischaemic stroke (74.5%) and intracerebral haemorrhage (23.4%) being the most frequent. No differences in diagnostic delay were found between the group of patients in whom the disease manifested with neurological complications and the rest of the patients (4.4 vs 4.5; P = .76). CONCLUSIONS: A total of 21.2% of patients with IE presented neurological complications, with ischaemic stroke being the most frequent. Neurological symptoms as the initial manifestation of IE did not lead to a delay in diagnosis.

Estudio descriptivo de la amiloidosis por transtiretina en un hospital de tercer nivel sin unidad de referencia / A descriptive study of transthyretin amyloidosis in a tertiary hospital without a referral unit

Antecedentes y objetivo: La amiloidosis por transtiretina (ATTR) es una enfermedad rara que forma parte de las amiloidosis sistémicas, y es una enfermedad amenazante para la vida. Puede afectar a todos los órganos y sistemas, siendo la más frecuente la afectación neurológica y cardíaca. El objetivo de este estudio es detectar posibles casos de ATTR y realizar un estudio descriptivo de los mismos. Material y métodos: Estudio descriptivo unicéntrico realizado en un hospital de tercer nivel en el que se incluyen pacientes con sospecha de ATTR entre septiembre de 2016 y enero de 2020. Resultados: Se detectan 190 pacientes sospechosos de ATTR. En el estudio se incluyen 100 de ellos, así como 10 familiares de pacientes en los que se detecta ATTR en su variante genética. En total, se detecta ATTR variante genética en 7 individuos (3 con mutación presintomática de la enfermedad), 16 pacientes con ATTR asociada a la edad y 31 individuos con amiloidosis cardíaca no filiada con las pruebas realizadas, lo que confirma la presencia de esta enfermedad en áreas no endémicas. Conclusiones: La ATTR es una enfermedad que se ha de tener en cuenta en el diagnóstico diferencial de pacientes que presentan insuficiencia cardíaca con FEVI preservada, principalmente si se asocia a síntomas neurológicos (AU)

Background and objective: Transthyretin amyloidosis (ATTR) is a rare disease that is part of systemic amyloidosis and is life-threatening. It can affect all organs and systems, the most frequent being neurological and cardiac involvement. This study aims to detect possible ATTR cases and carry out a descriptive study of them. Material and methods: Descriptive single-centre study carried out in a tertiary hospital, which included patients with suspected ATTR between September 2016 and January 2020. Results: A total of 190 suspected ATTR patients were detected. The study includes 100 of these patients, as well as 10 relatives of patients in whom ATTR was detected in its genetic variant (ATTRv). In total, ATTRv was detected in 7 individuals (3 with a presymptomatic mutation of the disease), 16 patients with age-related ATTR and 31 individuals with unknown cardiac amyloidosis with the tests performed, which confirms the presence of this disease in non-endemic areas. Conclusions: ATTR is a disease that must be taken into account in the differential diagnosis of patients with heart failure with preserved LVEF, especially if associated with neurological symptoms (AU)

Combined intracoronary thrombolysis, thrombus aspiration and mesh-covered stent implantation for organized massive thrombus burden in ectatic coronary.

Organized intracoronary thrombus is associated with adverse outcomes due to distal embolization and no-reflow phenomenon during PCI, particularly in large or ectatic coronary arteries. Intracoronary thrombolysis is an underused but effective and safe strategy. We describe the case of a 56-year-old man admitted due to a subacute myocardial infarction with massive thrombus burden in a right ectatic coronary artery to present the usefulness of a sequential approach with intracoronary thrombolysis, thrombus aspiration and a novel mesh-covered stent implantation as a reasonable and effective strategy to avoid a no-reflow phenomenon during PCI, achieving an immediate successful angiographic result, and a positive long-term clinical outcome.
