The definition, prevalence, classification and clinical relevance of anomalous origin of coronary arteries (AOCA) are still the subject of debate. Most international series estimate its prevalence at 1-2% but we found values ranging from 0.3 to 5.6% in the literature. The prevalence in our population was 0.54%, absence of the left main coronary artery being(More)
Noncompaction of the ventricular myocardium (NVM) is a rare congenital disease caused by an arrest in normal myocardial embryogenesis, leading to persistence of numerous prominent trabeculations which communicate with the left ventricle. It was first described as a congenital condition affecting children, but several cases have been reported of late(More)
Left-ventricular non-compaction (LVNC) is a rare congenital cardiopathy, which results from the failure of the myocardial compaction process, leading to the persistence of numerous and deep trabeculations communicating with the ventricular cavity. Its main clinical manifestations are heart failure, arrhythmias (supraventricular or ventricular) and episodes(More)
Isolated pulmonary valve endocarditis is a very rare entity, usually associated with intravenous drug abuse. We describe a case of isolated pulmonary valve endocarditis in a diabetic patient with no apparent precipitating factors besides a lesion on the right hallux. The clinical course was favorable and he was discharged home after a six-week course of(More)
AIMS Stratifying risk of sudden death is a major issue in the management of hypertrophic cardiomyopathy (HCM). Existing risk factors have low positive predictive value and new parameters are needed. Determination of myocardial deformation (strain) by 2D Speckle tracking is a new methodology for determining LV regional function and could correlate with(More)
AIMS Brugada syndrome (BrS) is a life-threatening arrhythmia disorder associated with autosomal-dominant mutations in the SCN5A gene. We aimed to characterize the diagnostic challenges and clinical manifestations of a novel SCN5A mutation associated with BrS. METHODS AND RESULTS From a novel SCN5A mutation (c.664C>T; p.Arg222X) identified in a proband(More)
Left ventricular noncompaction (LVNC) is a rare congenital disease caused by an arrest in normal myocardial embryogenesis, leading to persistence of numerous prominent trabeculations that communicate with the left ventricle. It was first described as a congenital condition affecting children, but several cases have been reported of late presentation. The(More)
Lupus is an inflammatory autoimmune disease that can affect multiple organ systems. As such, it can be diagnosed because of multiorgan or constitutional symptoms, but frequently medical treatment is sought only when there is clinical involvement of a particular organ or system, even if established--but undiagnosed--systemic disease is already present. The(More)
A 69-year-old man, with a history of hypertension, dyslipidemia, stroke in 1995 and left thoracic-abdominal trauma in 1999 resulting in hemopneumothorax after being hit by an ox, was referred for cardiology consultation following the incidental finding on thoracic-abdominal computed tomography (CT) of an extensive area (54 mm×36 mm×20 mm) of irregular,(More)
