BACKGROUND Accurate quantification of left ventricular (LV) volumes and ejection fraction (EF) is of critical importance. Cardiac magnetic resonance (CMR) is considered as the reference and three-dimensional echocardiography (3DE) is an accurate method, but only few data are available in heart failure patients. We therefore sought to compare the accuracy of(More)
Cardiopulmonary exercise testing (CPX) has become the cornerstone of risk stratification for heart failure patients. Peak oxygen consumption (VO2) was the first CPX variable to demonstrate prognostic value and is still the most frequently analyzed variable in clinical practice. More recently, several investigations have shown that ventilatory efficiency,(More)
BACKGROUND AND PURPOSE The high risk of recurrence and comorbidity after a stroke associated with atrial fibrillation (AF) justifies an aggressive diagnostic approach so that anticoagulant treatment can be initiated. METHODS The clinical and paraclinical characteristics of consecutive ischemic stroke patients with and without documented AF were recorded.(More)
BACKGROUND Patent foramen ovale (PFO) in pulmonary embolism (PE) is associated with an increased risk of complications. However, little is known about PFO and ischemic stroke prevalence, particularly in acute intermediate-risk PE. In addition, in this context, the so-called "gold standard" method of PFO diagnosis remains unknown. We aimed to evaluate PFO(More)
INTRODUCTION The ultrasound assessment of RV structure and function is often sub-optimal. The range of excursions of the mitral or tricuspid annulus measured in millimetre by 2D or TM-mode in centimetre per second by DTI-mode echocardiography has been shown to reflect the systolic function of both ventricles. METHODS We studied a new technique based on a(More)
Strokes in young patients may be the clinical expression of many complex and extremely rare diseases. Uncommon causes constitute less than 5% of all strokes, but are present in 30% of strokes in young patients. We report the case of a young woman whose ischemic stroke led to the diagnosis of a rare embolic cardiomyopathy, left ventricular noncompaction(More)
