Introdução: A ablação septal alcoólica (ASA) é a forma percutânea de tratamento invasivo da cardiomiopatia hipertrófica obstrutiva (CMHO). A propósito da descrição da experiência no nosso centro, procurar-se-á rever as indicações, os aspetos técnicos e práticos e os resultados da ASA, assim como a sua posição atual em comparação com a miectomia cirúrgica.Objetivo: Avaliar os resultados da ASA numa série de doen...
AIMS: To evaluate the long-term clinical outcomes following percutaneous coronary intervention (PCI) with the Genous stent in an unselected population. METHODS: All patients admitted to a single center who underwent PCI using the GS exclusively, between May 2006 and May 2012, were enrolled, and a clinical follow-up of up to 60 months was carried out. The primary endpoint of major adverse cardiac event (MACE) r...
PURPOSE: The Genous™ stent (GS) is designed to accelerate endothelization, which is potentially useful in the pro-thrombotic environment of ST-elevation acute myocardial infarction (STEMI). We aimed to evaluate the safety and effectiveness of the GS in the first year following primary percutaneous coronary intervention (PCI) and to compare our results with the few previously published studies. METHODS AND MATE...
Apresentamos o caso de um doente, previamente submetido a angioplastia coronária com um stent revestido com fármaco, com enfarte agudo do miocárdio (EAM) provocado por trombose tardia do stent, tendo sido detectada fractura do mesmo. Este caso vem reforçar o reconhecimento crescente da fractura como potencial mecanismo para a trombose tardia de stent, na era dos stents revestidos com fármaco. A propósito deste ...
Percutaneous transluminal coronary angioplasty (PTCA) with stent placement is widely used to achieve myocardial revascularization in patients with symptomatic ischemic heart disease and significant coronary artery stenosis. Drug-eluting stents are used in most patients undergoing percutaneous angioplasty. Stent thrombosis is an uncommon but serious complication, manifested mostly by sudden death or acute ST-ele...
INTRODUCTION: Primary angioplasty is accepted as the preferred treatment for acute myocardial infarction in the first 12 hours. However, outcomes depend to a large extent on the volume of activity and experience of the center. Continuous monitoring of methods and results obtained is therefore crucial to quality control. OBJECTIVE: To describe the demographic, clinical and angiographic characteristics as well a...
BACKGROUND: ST-elevation myocardial infarction (STEMI) with the culprit lesion in the left main artery is a rare cardiac emergency with a poor prognosis. OBJECTIVE: Review and prognosis evaluation of primary percutaneous coronary intervention (PCI) performed in the setting of STEMI with left main occlusion in a single high-volume center. METHODS: Of the 483 primary or rescue PCIs performed and followed in our...
INTRODUCTION: The use of drug-eluting stents in the context of mechanical reperfusion following ST-segment elevation myocardial infarction (MI) was initially viewed with concern. The main fear was that the drugs' action in unstable lesions could increase the risk of thrombotic stent occlusion. Furthermore, there was no evidence that the proven benefit of reduced instent restenosis could be extended to such pati...
Introdução: A angioplastia primária é a terapêutica de reperfusão com melhores resultados no enfarte agudo do miocárdio (EAM). Este facto assume particular relevância na população acima dos 75 anos, em que o risco hemorrágico relacionado com a trombólise se associa ao acréscimo de mortalidade condicionado pela idade. Objectivos: Avaliar em doentes com síndrome coronário agudo (SCA) com supradesnivelamento do s...
