Mitral Valve Diseases, Congenital and Acquired

Congenital mitral anomalies are rare as isolated lesion. These anomalies are frequently encountered in combination with other lesions such as atrioventricular septal defects, Shone complex, hypoplastic left heart syndrome (HLHS). Mitral valve prolapse and rheumatismal mitral valve diseases are more common in older children or adolescents. Three-dimensional echocardiography (3D) allows visualization of mitral valve, as it looks in reality and provide its anatomical details.
