Oclusão percutânea do apêndice atrial esquerdo com o Amplatzer Cardiac PlugTM na fibrilação atrial
Fundamento: A fibrilação atrial está associada a acidentes vasculares embólicos que frequentemente resultam em morte ou invalidez. Eficaz na redução desses eventos, a anticoagulação possui várias limitações e vem sendo amplamente subutilizada. Mais de 90%

Oclusao percutânea do apêndice atrial esquerdo em paciente com fibrilaçao atrial e malformaçao arteriovenosa cerebral [PDF]
A fibrilaçao atrial é a arritmia mais relacionada à ocorrência de acidentes vasculares cerebrais isquêmicos. A prevençao desses eventos é o principal desafio no tratamento dos portadores de fibrilaçao atrial.

Altered excitation-contraction coupling in human chronic atrial fibrillation [PDF]
This review focuses on the (mal)adaptive processes in atrial excitation-contraction coupling occurring in patients with chronic atrial fibrillation. Cellular remodeling includes shortening of the atrial action potential duration and effective refractory ...

Post-operative atrial fibrillation is influenced by beta-blocker therapy but not by pre-operative atrial cellular electrophysiology [PDF]
We investigated whether post-cardiac surgery (CS) new-onset atrial fibrillation (AF) is predicted by pre-CS atrial cellular electrophysiology, and whether the antiarrhythmic effect of beta-blocker therapy may involve pre-CS pharmacological remodeling ...

Aneurisma de apêndice atrial esquerdo: um achado radiográfico acidental - relato de caso
Left atrial appendage aneurysm is an extremely rare condition. It usually oc-curs together with changes in the mitral valve and manifests itself with cardiac arrhythmias or thromboembolisms, most commonly between the second and fourth decade of life.

Resumo: A fibrilhação auricular é uma arritmia frequente na prática clínica. Associa-se a morbilidade e a mortalidade elevadas, em virtude do seu potencial tromboembólico, o que confere especial relevância à profilaxia do tromboembolismo.

Percutaneous closure of iatrogenic femoral arteriovenous fistula using a covered coronary stent
We present the case of a patient with a high-output fistula between the right superficial femoral artery and femoral vein after left atrial appendage closure successfully treated with a PK-Papyrus covered coronary stent using a 6F guiding catheter.

Electrophysiological and arrhythmogenic effects of 5-hydroxytryptamine on human atrial cells are reduced in atrial fibrillation [PDF]
5-Hydroxytryptamine (5-HT) is proarrhythmic in atrial cells from patients in sinus rhythm (SR) via activation of 5-HT<sub>4</sub> receptors, but its effects in atrial cells from patients with atrial fibrillation (AF) are unknown.

Textura de bioprótese mitral, função ventricular esquerda e formação de trombo: análise por ecocardiografia transesofágica e aplicação de bioescore [PDF]
OBJETIVO: Diante da hipótese da participação do estresse mecânico como causa de disfunção de bioprótese mitral, decidimos avaliar a relação da preservação da textura dos folhetos da bioprótese mitral com a função ventricular esquerda, adicionalmente à ...

Atrial cellular electrophysiological changes in patients with ventricular dysfunction may predispose to AF [PDF]
<b>Background:</b> Left ventricular systolic dysfunction (LVSD) is a risk factor for atrial fibrillation (AF), but the atrial cellular electrophysiological mechanisms in humans are unclear.
