Non-vitamin K antagonist oral anticoagulation versus left atrial appendage occl...

Introduction: This study aimed to evaluate the performance of non-vitamin K antagonist oral anticoagulation (NOAC) in patients with previous stroke and non-valvular atrial fibrillation (AF) compared with left atrial appendage occlusion (LAAO) in primary and secondary stroke prevention settings. Methods: This was a prospective, single-center, non-randomized cohort study of 302 consecutive patients with non-valvu...

Fusion imaging in interventional cardiology

The number and complexity of percutaneous interventions for the treatment of structural heart disease has increased in clinical practice in parallel with the development of new imaging technologies, in order to render these interventions safer and more accurate. Complementary imaging modalities are commonly used, but they require additional mental reconstruction and effort by the interventional team. The concep...

Annotation rules for XML schemas with grouped semantic annotations

To enable the Industrial Internet of Things (IIoT), it is required to ensure Machine-to-Machine communications. Systems/devices often use different communication protocols, standards, and data representation languages, which create interoperability challenges. This paper proposes a set of annotation rules for systems meta-data, to support the translation of data exchanged between heterogeneous systems. These ru...

Dissecção coronária espontânea --- "To stent or not to stent that is the question"

A dissec¸ão coronária espontânea é uma causa rara de síndrome coronária aguda e ocorre tipicamente em indivíduos jovens sem os fatores de risco cardiovasculares clássicos de doenc¸a arterial coronária. Apresenta etiologia multifatorial e tratamento não definido, pelo que a sua abordagem deve ser feita de forma selecionada baseada na apresentac¸ão clinica e anatomia coronária. Apresentam-se dois casos clínicos d...

Risk stratification in acute coronary syndromes: Graced by a new score?

Desfecho desfavorável após cirurgia de substituição valvular

Additional value of associating aortic valve calcification to coronary calcium ...

Background: Aortic valve calcification shares risk factors with coronary artery disease. Coronary calcium has been used has a gatekeeper to performing coronary tomography angiography. The aim of this study was to evaluate aortic valve calcification as a predictor of obstructive coronary artery disease by computed tomography, and its possible usefulness, alongside with coronary calcium, to improve the decision o...

Implantable cardioverter-defibrillators in the elderly: rationale and specific ...

Despite the increasingly high rate of implantation of cardioverter-defibrillators (ICD) in elderly patients, data supporting their clinical and cost-effectiveness in this age stratum are ambiguous and contradictory. We comprehensively reviewed the state-of-the-art data regarding the applicability, safety, clinical- and cost-effectiveness of the ICD in elderly patients, and analysed which patients in this age st...

Which method of left atrium size quantification is the most accurate to recogni...

Background: Left atrial (LA) size is a predictor of cardiovascular outcomes in patients in sinus rhythm, whereas conflicting results have been found in atrial fibrillation (AF). This study aims to: (1) Evaluate the accuracy of LA size to identify surrogate markers of an increased thromboembolic risk in patients with AF; (2) Assess the best method to evaluate LA size in this setting. Methods: Cross-sectional stu...

Mean platelet volume is associated with the presence of left atrial stasis in p...

Background: Mean platelet volume has been associated with stroke in patients with atrial fibrillation. However, its role as a predictor of left atrial stasis, assessed by transesophageal echocardiography, in patients with non-valvular atrial fibrillation has not yet been clarified. Methods: Single center cross-sectional study comprising 427 patients admitted to the emergency department due to symptomatic atrial...
