Identification of Genetic Basis of Atrioventricular Conduction Defects: From Congenital Forms to Degenerative Forms
Identification of genes involved in congenital atrioventricular block and progressive Cardiac Conduction Disease.
• Patients with idiopathic congenital atrioventricular block diagnosed before the age of 15 years.
• Non-immune congenital atrioventricular block documented by a maternal serology (negative for anti-nuclear antibodies or anti Ro-SSA antibodies and anti La-SSB antibodies)
• Written consent to participate to the study and written consent of both parents.
• Parents of children with idiopathic congenital atrioventricular block.
• Patients with isolated cardiac conduction disorder with a normal morphology of the heart confirmed by echocardiography.
• Relatives of patients with isolated cardiac conduction disorder
• Written consent to participate to the study
