Autonomic denervation is an alternative approach for patients with symptomatic bradycardia. No consensus exists on the critical targets and end points of procedure. The aim this study was to identify immediate atrial regions responsible vagal denervation.We enrolled 14 (50% men; age: 34.0±13.8 years) cardioinhibitory syncope, advanced atrioventricular block or sinus arrest, no structural heart disease. Anatomic mapping ganglionated plexuses performed, followed by radiofrequency ablation....
Cotton is an important economic crop; therefore, enhancing cotton yield and cultivating superior varieties are key research priorities. The seedling stage, a critical phase in production, significantly influences the subsequent growth of crop. Therefore, breeding experts often choose to measure phenotypic parameters during this period make decisions. Traditional methods parameter measurement require manual processes, which not only tedious inefficient but can also damage plants. To...
Aim Acute and subacute cardiotoxicity are characterized by prolongation of the corrected QT interval (QTc) other measures derived from QTc interval, such as dispersion (QTdc) transmural repolarization (DTpTe). Although anthracyclines prolong it is unclear whether breast cancer patients who undergo ACT chemotherapy regimen anthracycline (doxorubicin: A), cyclophosphamide (C) taxane (T) may present with QTc, QTdc DTpTe prolongation. Methods Twenty-three consecutive were followed prospectively...
Cardioneural ablation is a novel treatment for functional bradycardia. However, the risk of acute complications still unknown. The aim this case report to describe occlusion sinus node artery after cardiac denervation procedures in 2 patients and encourage measures prevent it, such as evaluating aortic angulation older before procedure by monitoring signs failure during with electroanatomical maps showing constricted aspect right atrium. (Level Difficulty: Advanced.).
Resumo Fundamento A ocorrência de fístula atrioesofágica após o procedimento ode ablação fibrilação atrial (FA) continua uma preocupação. Não existe abordagem padronizada para minimizar seus riscos e mortalidade. Objetivos Apresentar a experiência sete anos um monitoramento endoscópico sistemático lesão esofágica FA por cateter. Métodos Estudo unicêntrico retrospectivo avaliação endoscópica sistemática em procedimentos consecutivos realizados entre 2016 2022. Um valor p < 0.05 foi...
Abstract Background Atrial-esophageal fistula following AF ablation remains a concern. There is no standardized approach to minimize its risk and morbidity. Objective To present the seven-year experience of systematic endoscopic surveillance esophageal injury after catheter ablation. Methods This retrospective single center registry evaluation in consecutive procedures performed from 2016 2022. A p-value <0.05 was considered statistically significant. Results 823 with controlled...
Introduction: The echocardiographic diagnosis criteria for arrhythmogenic right ventricular cardiomyopathy (ARVC) are highly specific but sensitivity is low, especially in the early stages of disease. role strain ARVC has not been fully elucidated, although prior studies suggest that it can improve detection subtle functional abnormalities. purposes study were to determine whether these advanced measures (RV) dysfunction on echocardiogram, including RV strain, increase diagnostic value...
Abstract Background There are no randomized studies comparing the maintenance of sinus rhythm after catheter ablation (CA) concerning treatment with antiarrhythmic drugs (AA) in elderly patients paroxysmal atrial fibrillation (AF). Objectives To compare clinical results pulmonary vein (PV) isolation second-generation PVAC Gold against AA people recurrent symptomatic AF, refractory to at least one AA, and without structural heart disease. Methods Sixty AF ≥ 65 years old were two forms...
Brugada Syndrome (BrS) typically manifests with a dynamic type 1 pattern (Br1ECGp) that depends on the dominance of sympathetic or parasympathetic nervous system. This is more prominent during activities stimulate vagus nerve, such as sleeping and after meals. By conducting tilt table test adding high precordial leads to standard protocol, it possible provoke responses, providing valuable information. was an observational, cross-sectional hypothesis-generating pilot study. The performed...
Mutations in the Lamin A/C(LMNA) gene are commonly associated with cardiac manifestations, such as dilated cardiomyopathy (DCM) and conduction system disease. However, overall spectrum penetrance of rare LMNA variants unknown. The present study described presence LMNAvariants patients "lone atrial fibrillation (AF)" their sole clinical presentation.One-hundred one consecutive AF" criteria were initially screened by genetic testing. Genetic classified according to American College Genomic...
Space target recognition plays an important role in the field of space security and exploration. With rapid development artificial intelligence technique explosive increase image dataset, object based on deep learning has achieved favorable performance. However, targets visible spectrum images still remains traditional manual interpretation approach, thus leading to low efficiency inevitable subjective errors. In this paper, we propose method for recognition, called Two-Stage Convolutional...
Arrhythmogenic right ventricular cardiomyopathy (ARVC), a rare inherited disease, causes tachycardia, sudden cardiac death, and heart failure (HF). We investigated ARVC clinical features, genetic findings, natural history, the occurrence of life-threatening arrhythmic events (LTAEs), HF or transplantation (HF-death/HTx) to identify risk factors.The course 111 consecutive patients with definite ARVC, predictors LTAE, HF-death/HTx, combined were analyzed in entire cohort subgroup 40 without...
Background Brugada syndrome and long-QT may account for at least one third of unexplained sudden cardiac deaths. Dental care in patients with channelopathies is challenging because the potential risk life-threatening events. We hypothesized that use local dental anesthesia lidocaine without epinephrine safe does not result arrhythmias channelopathies. Methods Results performed a randomized, double-blind pilot trial comparing 2% vasoconstrictor 1:100 000 2 sessions restorative treatment...

Introducao Em dezembro de 2019, foram relatados os primeiros casos da doenca causada pelo novo coronavirus (COVID-19), originarios Wuhan, China. Desde a declaracao pandemia em marco 2020 por Organizacao Mundial Saude (OMS), com disseminacao intercontinental, vivenciamos intensa busca um tratamento seguro e eficaz. Estudos in vitro demonstraram algum efeito cloroquina contra o coronavirus, intermediada pela glicosilacao dos receptores celulares SARS-CoV aumento do pH endossomico, bloqueando...
