Gerbode defect is a rare type of left ventricle to right atrium shunt. It is usually congenital in origin, but acquired cases are also described, mainly following infective endocarditis, valve replacement, trauma or acute myocardial infarction. We report a case of a 50-year-old man who suffered an extensive and complex infective endocarditis involving a(More)
AIMS Catheter ablation (CA) of atrial fibrillation (AF) might be a definitive curative therapy for selected groups of patients (pts). However, current ablation protocols are not standardized and predictors of CA success and sinus rhythm maintenance are not clearly defined. To evaluate whether left atrium (LA) volume quantification provided by multi-detector(More)
INTRODUCTION Pulmonary embolism (PE) is an entity with high mortality and morbidity, in which risk stratification for adverse events is essential. N-terminal brain natriuretic peptide (NT-proBNP), a right ventricular dysfunction marker, may be useful in assessing the short-term prognosis of patients with PE. AIMS To characterize a sample of patients(More)
BACKGROUND Trastuzumab (TZB) is a recombinant humanized monoclonal antibody, used for the treatment of HER2-positive breast cancer, with recognized associated-cardiotoxicity. The methods for its early sub-clinical detection are not well defined. OBJECTIVE To evaluate TZB-induced cardiotoxicity in patients (pts) with breast cancer followed for a 3-month(More)
The role of depression in cardiovascular disease is increasingly emphasized. Whether it precedes or follows coronary events, it is an obstacle to adherence to preventive measures and physical recovery. Between January and November 2005, we interviewed 82 patients admitted to a central hospital, with a discharge diagnosis of acute myocardial infarction (MI),(More)
One of the points that differentiates most Linux distributions nowadays is the meta-installer. Meta-installers are software programs that run over RPM / DEB / TGZ installation systems, providing for automatic resolution of dependencies. Meta-installers like Apt-get, Smart or Yum are used widely and are starting to have more features. A framework for the new(More)
INTRODUCTION Acute pulmonary embolism (PE) is a common clinical entity in the emergency department, and remains a diagnostic challenge for physicians. The role of the 12-lead electrocardiogram (ECG) in its diagnosis and assessment of severity and prognosis is not as well defined as for acute coronary syndromes. We report four cases of massive and submassive(More)
INTRODUCTION According to the current guidelines for treatment of ST-elevation myocardial infarction (STEMI), percutaneous coronary intervention (PCI) should be performed within 90 min of first medical contact and total ischemic time should not exceed 120 min. The aim of this study was to analyze compliance with STEMI guidelines in a tertiary PCI center. (More)
Left ventricular pseudoaneurysm is a rare complication of acute myocardial infarction, associated with high mortality. However, it can present in a non-specific manner, complicating and delaying the diagnosis. The authors present the case of a 65-year-old patient, hypertensive, with no other known relevant medical history, who presented with chest pain,(More)
