OBJECTIVES The aim of this study was to analyze the long-term follow-up of dilated cardiolaminopathies. BACKGROUND Lamin A/C (LMNA) gene mutations cause a variety of phenotypes. In the cardiology setting, patients diagnosed with idiopathic dilated cardiomyopathy (DCM) plus atrioventricular block (AVB) constitute the majority of reported cases. METHODS(More)
Left ventricular ejection fraction (LVEF) ≤35% is a major determinant for implantable cardioverter-defibrillator (ICD) therapy for primary prevention of sudden death (SD) in patients with non-ischaemic dilated cardiomyopathy (DCM). However, as a risk marker for SD, low LVEF has limited sensibility and specificity. Selecting patients according to the current(More)
OBJECTIVES We sought to describe the diagnostic work-up, phenotype, and long-term evolution of dilated cardiomyopathy (DCM) associated with Dystrophin (DYS) defects. BACKGROUND X-linked DCM associated with DYS defects can be clinically indistinguishable from other types of DCM. METHODS The series comprises 436 consecutive male patients diagnosed with(More)
OBJECTIVES The authors sought to investigate the gene and protein expression in Lamin A/C (LMNA)-mutated dilated cardiolaminopathy (DCM) patients (DCM(LMNAMut)) versus LMNA-wild-type DCM (DCM(LMNAWT)), and normal controls (CTRL(LMNAWT)). BACKGROUND Dilated cardiolaminopathies are clinically characterized by high arrhythmogenic risk and caused by LMNA(More)
The gold standard for the study of the macro-anatomy of the aortic root are multi-detector computed tomography (MDCT) and magnetic resonance (MR) imaging. Both technologies have major advantages and limitations. Although 4D echo is entering the study of the aortic root, 2D echo is the most commonly used diagnostic tool in daily practice. We designed and(More)
OBJECTIVE To evaluate the prevalence and phenotype of smooth muscle alpha-actin (ACTA2) mutations in non-syndromic thoracic aortic aneurysms and dissections (TAAD). DESIGN Observational study of ACTA2 mutations in TAAD. SETTING Centre for Inherited Cardiovascular Diseases. PATIENTS A consecutive series of 100 patients with TAAD. Exclusion criteria(More)
BACKGROUND The major clinical problem of Marfan syndrome (MFS) is the aortic root aneurysm, with risk of dissection when the root diameter approximates 5 cm. In MFS, a key molecule, transforming growth factor-beta (TGF-beta), normally bound to the extracellular matrix, is free and activated. In an experimental setting, TGF-beta blockade prevents the aortic(More)
BACKGROUND Atrial dilatation and atrial standstill are etiologically heterogeneous phenotypes with poorly defined nosology. In 1983, we described 8-years follow-up of atrial dilatation with standstill evolution in 8 patients from 3 families. We later identified 5 additional patients with identical phenotypes: 1 member of the largest original family and 4(More)
OBJECTIVES The INHERITANCE project, funded by the European Commission, is aimed at studying genetic or inherited Dilated cardiomyopathies (DCM) and at understanding the impact and management of the disease within families that suffer from heart conditions that are caused by DCMs. The biomedical informatics research activity of the project aims at(More)
