Very-early detection of atrial fibrillation after ablation evaluated by a weara...
Marques Antunes, Miguel; Cunha, Pedro; Lacerda Teixeira, Bárbara; Portugal, Guilherme; Valente, Bruno; Lousinha, Ana; Delgado, Ana Sofia; Alves, SandraIntroduction: Atrial fibrillation (AF) ablation represents a safe and effective procedure to restore sinus rhythm. The idea that post-procedural AF episodes - during the blanking period - are not considered treatment failure has been increasingly challenged. The E-Patch, a single-use adhesive electrode, facilitates extended continuous ECG monitoring for 120 h. This pilot study aims to assess the effectiveness o...
Epicardial adipose tissue volume assessed by cardiac CT as a predictor of atria...
Teixeira, Bárbara Lacerda; Cunha, Pedro; Jacinto, Ana Sofia; Portugal, Guilherme; Laranjo, Sergio; Valente, Bruno; Lousinha, AnaIntroduction: In patients with atrial fibrillation (AF), up to one third have recurrence after a first catheter ablation (CA). Epicardial adipose tissue (EAT) has been considered to be closely related to AF, with a potential role in its recurrence. We aimed to evaluate the association between the volume of EAT measured by cardiac computed tomography (CT) and AF recurrence after CA. Methods: Consecutive AF patie...
The atrial fibrillation burden during the blanking period is predictive of time...
Cunha, Pedro; Portugal, Guilherme; Laranjo, Sérgio; Alves, Marta; Luísa Papoila, Ana; Valente, Bruno; Sofia Delgado, Ana; Lousinha, AnaObjective: This study aimed to assess whether atrial fibrillation (AF) occurrence or its corresponding daily mean burden (in minutes/day) during the mid to late blanking period after pulmonary vein isolation (PVI), predicts AF recurrence. Methods: Analysis of consecutive first PVI ablation patients undergoing prolonged electrocardiogram (ECG) monitoring during the second and third months after PVI. The clinical...

Duarte, João; Sousa, Francisco; Valente, Bruno7th World Multidisciplinary Earth Sciences Symposium, WMESS 2021. Prague. 6 September 2021 through 10 September 2021; As part of the strategy for Industry 4.0, this work was developed to outline a methodology that is an important contribution to improve the efficiency and productivity of processes in the ornamental stone extraction industry. Since this sector is important for the Portuguese economy, it is imper...
Lockdown measures for COVID-19 outbreak and variation in physical activity in p...
Silva Cunha, Pedro; Laranjo, Sérgio; Lourenço, André; Rodrigues, Lourenço; Cardoso, Isabel; Portugal, Guilherme; Valente, Bruno; Delgado, Ana SofiaAims: The present study analysed the patterns of physical activity pre-, during and post-lockdown measures for COVID-19 pandemic in patients with chronic heart failure (CHF) and cardiac implantable electronic devices (CIED) under remote monitoring (RM), and assessed the physical activity patterns during these periods. Methods: The raw data from 95 patients with CHF (age 67,7 +/- 15,1 years, 71,5% male) correspo...
Programas auxiliares de processamento de dados e de resultados de dois programa...
Martins, Francisco F.; Valente, BrunoNeste trabalho são apresentados dois programas auxiliares no pré-processamento dos dados (MALHAS2D e MALHAS3D) e no pós-processamento dos resultados (MALHAS3D) de dois programas de simulação numérica de túneis a duas e três dimensões. Estes programas, escritos na linguagem de programação Visual Basic, permitem gerar a malha de elementos finitos e definir os diferentes estratos do terreno, o suporte do túnel, a ...
Análise tridimensional do comportamento de um túnel superficial em meio urbano
Martins, Francisco F.; Valente, Bruno; Sousa, Jorge Almeida eTrata-se da simulação numérica da abertura de um túnel superficial aberto em formações miocénicas de natureza argilo-siltosa, próximo da Estação do Oriente em Lisboa (Túnel DMC Norte no troço 96º do Metropolitano de Lisboa). O túnel, com um desenvolvimento longitudinal de 80m e um diâmetro equivalente de cerca de 11,5m, foi construído de acordo com os princípios do NATM. Os cálculos numéricos envolveram análise...
