A great deal of evidences indicate that impaired fetal growth and in utero exposure to risk factors, especially maternal hypercholesterolemia, may be relevant for human pathophysiological signs of atherosclerosis and subsequent development of cardiov...

Restrictive cardiomyopathy (RCM) is defined on the basis of the haemodynamic finding of restrictive ventricular physiology. However, restrictive ventricular pathophysiology is also a feature of other subtypes of cardiomyopathy, including hypertrophic...

The authors describe different bioinformatic approaches to cardiovascular research, focusing on: (i) the complexity of cardiovascular diseases; (ii) how does systems biology work and its application to cardiology; (iii) new systems research in cardio...

Loss-of-function mutations in the SCN5A gene, encoding the cardiac Nav1.5 sodium channel, have been previously associated with Brugada syndrome (BrS). Despite the low prevalence of the disease, we identified a patient carrying two SCN5A mutations. We...

A 35-year-old woman was referred to our centre for clinical management of hypertrophic cardiomyopathy (HCM) with left ventricular (LV) systolic dysfunction (end-stage evolution). She was recently diagnosed elsewhere because of palpitations. Her 7-yea...

Major advances have been achieved over the two last decades in the field of genetic cardiovascular diseases, not only through increased recognition and understanding of underlying molecular defects but also through rapid translation of knowledge into...

Hypertrophic cardiomyopathy (HCM) is characterized by unexplained left ventricular hypertrophy. HCM is often hereditary, but our knowledge of the mechanisms leading from mutation to phenotype is incomplete. The transcriptional expression patterns in...

The identification of molecular anomalies in patients with inherited arrhythmias or cardiomyopathies is a multi challenge due to: i) the number of genes involved; ii) the number of polymorphisms and the fact that most mutations are private; and iii)...

Idiopathic restrictive cardiomyopathy (IRC) is a rare form of heart muscle disease. Genetic studies have revealed that in about half the cases, IRC forms part of the hereditary sarcomeric contractile protein disease spectrum. Mutations in several sar...

Pediatric cardiomyopathy is a genetically heterogeneous disease associated with significant morbidity. Although identification of underlying etiology is important for management, therapy, and screening of at risk family members, molecular diagnosis i...

Myxomas are the most common primary cardiac tumors, with an estimated incidence of 0.5 per million per year. Familial myxoma constitutes 10% of all myxomas, among these tumors, one in ten is part of Carney complex - an autosomal dominant syndrome, wh...

Alström syndrome is a rare autosomal recessive disorder with dilated cardiomyopathy in 60% of patients. Despite the frequency of cardiac involvement in Alström syndrome, conduction system abnormalities or arrhythmias have not been characterized previ...

Idiopathic ventricular fibrillation can be caused by subclinical channelopathies such as Brugada syndrome. Our objective is to study the clinical behaviour of a new SCN5A mutation found in a woman with idiopathic ventricular fibrillation. A 53-year-o...
