INTRODUCTION In pulmonary embolism (PE) without hemodynamic compromise, the prognostic value of right ventricular (RV) dysfunction as measured by echocardiography, computed tomography (CT) or biological (natriuretic peptides) markers has only been assessed in small studies. METHODS Databases were searched using the combined medical subject headings for(More)
BACKGROUND Single center studies using serial cerebral diffusion-weighted magnetic resonance imaging in patients having cardiac catheterization have suggested that cerebral microembolism might be responsible for silent cerebral infarct (SCI) as high as 15% to 22%. We evaluated in a multicenter trial the incidence of SCIs after cardiac catheterization and(More)
AIMS We sought to describe our experience with major coronary anomalies (MCAs) diagnosed in transthoracic echocardiography (TTE) in a large adult and paediatric population. MCAs may have serious clinical consequences. No echocardiographic studies have prospectively screened MCA in a general adult and paediatric population. METHODS AND RESULTS From June(More)
In recent years, heart failure has been recognized as a major and increasing public health issue. In the context of the shortage of heart donors and increasing waiting time on the transplantation list, nonpulsatile left ventricular assist devices (LVAD) have shown their efficiency in reducing mortality and improving quality of life in patients with(More)
BACKGROUND Arterial hypertension (AH) induces cardiac hypertrophy and reactivation of "fetal" gene expression. In rodent heart, alpha-Myosin Heavy Chain (MyHC) and its micro-RNA miR-208a regulate the expression of beta-MyHC and of its intronic miR-208b. However, the role of aldosterone in these processes remains unclear. METHODOLOGY/PRINCIPAL FINDINGS(More)
Transdiaphragmatic peritoneopericardial hernia is a rare complication after peritoneopericardial window formation, coronary artery bypass grafting using the gastroepiploic artery, or subxiphoid epicardial pacemaker insertion. We describe two different clinical presentations of transdiaphragmatic peritoneopericardial hernia in patients who had undergone(More)
We report the case of a 64-year-old Jarvik 2000 recipient with a high risk of bleeding (anticoagulation treatment and acquired von Willebrand disease), who presented with intractable gastrointestinal hemorrhage due to severe gastric angiodysplasia. He was successfully treated with long-acting octreotide.
BACKGROUND Late antibody-mediated rejection (AMR) after heart transplantation is suspected to be associated with a poor short-term prognosis. METHODS A retrospective single-center observational study was performed. Late AMR was defined as AMR occurring at least 1 year after heart transplantation. The study included all consecutive patients with proven and(More)
INTRODUCTION The relationship between brain natriuretic peptide (BNP) increase in acute pulmonary embolism (PE) and the increase in mortality and morbidity has frequently been suggested in small studies but its global prognostic performance remains largely undefined. We performed a systematic review and meta-analysis of data to examine the prognostic value(More)
