Viability of wall-embedded tag antenna for ultra-wideband real-time suitcase lo...

WOS:000335152600007 (Nº de Acesso Web of Science) ; Viability of a conformal single-layer monopole antenna is studied for a wall-embedded tag in an ultra-wideband (UWB) suitcase localisation application based on impulse radio UWB. The performance of the embedded antenna is simulated and confirmed experimentally in real-time localisation (RTL) experiments carried out in a cluttered laboratory environment. Evalu...

Mean pulmonary arterial pressure after percutaneous mitral valvuloplasty predic...

INTRODUCTION AND AIM: Percutaneous mitral valvuloplasty (PMV) is an effective treatment option for mitral stenosis (MS), but its success is assessed on the basis of clinical and echocardiographic outcomes in studies with relatively short follow-up. We aimed to characterize a cohort of patients undergoing PMV with long-term follow-up and to determine independent predictors of post-PMV mitral re-intervention and ...

Complications of endomyocardial biopsy in heart transplant patients: a retrospe...

BACKGROUND: Endomyocardial biopsy (EMB) remains the gold standard for the diagnosis of graft rejection after heart transplantation (HT). Our purpose was to evaluate the rate of complications of this invasive procedure. METHODS: This was a retrospective study of 175 patients, who were transplanted between November 2003 and October 2010 and survived more than 1 month after surgery. We evaluated the number of inc...

Embolia coronária aguda em portadora de prótese aórtica mecânica: caso clínico

Embolic myocardial infarction is a rare entity, which is often difficult to diagnose, and there is little agreement on its treatment. Patients with prosthetic valves are considered an important risk group. A 71-year-old woman with a mechanical aortic prosthesis was admitted with anterior ST segment elevation myocardial infarction after two hours of symptoms. Emergency angiography revealed an image suggestive of...

Estudo das fácies de leque aluvial em afloramento do Triásico Superior de Coimb...

A realização de um perfil litostratigráfico de pormenor em depósitos triásicos na região de Coimbra permitiu o reconhecimento de fácies sedimentares, a sua caracterização e interpretação tectonosedimentar. As conclusões encontram-se em concordância com as etapas iniciais da evolução geológica da Bacia Lusitânica largamente exposta na bibliografia existente. ; construction of a detailed litostratigraphyc prof...

Sistemas de falhas em afloramentos do Triásico Superior na região de Coimbra

A partir da análise estrutural dos sistemas de falhas em afloramentos do Triásico Superior localizados na região de Coimbra, na Bacia Lusitânica, foi possível definir famílias e sub-famílias de falhas. Este trabalho permitiu reconhecer que os acidentes tectónicos extensionais que afectaram os depósitos do Triásico nesta região, durante toda a evolução do contexto tectónico do Mesozóico foram sistematicamente re...

Results of the routine use of 4F catheters for diagnostic catheterization in a ...

INTRODUCTION: Complications at the site of vascular access are the most common adverse events in cardiac catheterization. The use of small gauge catheters may reduce this risk and allow earlier ambulation, the main disadvantage according to some authors being inferior image quality. The aim of our study was to evaluate the safety and image quality of 4 French diagnostic catheters. METHODS: We performed a retro...

Invasive strategy in non-ST elevation acute coronary syndromes: risks and benef...

Coronary fistulas after cardiac transplantation

Maturação orgânica e palinoestratigrafia da Sondagem RUIVO-1, região imersa da ...

A sondagem RUIVO-1, localizada na região imersa da Bacia Algarvia, foi estudada com a finalidade de se caracterizar o grau de maturação e conhecer as idades das unidades litológicas com base na bioestratigrafia dos dinoflagelados. O estudo do poder reflector da vitrinite indica que a sucessão do Mesozóico está matura em relação à "janela do petróleo". Os dinoflagelados evidenciaram a presença de uma espessa ...
