Elongation of the aorta and multiple cardiovascular abnormalities associated with larsen syndrome.

Larsen syndrome is a genetically heterogeneous group of disorders characterized by multiple joint dislocations and a characteristic face. We describe a girl with the typical features of Larsen syndrome. She also had associated multiple cardiovascular anomalies. The anomalies included elongation of the aorta, bicuspid aortic valve, subaortic stenosis, mitral valve prolapse with mitral regurgitation, atrial septal defect of the secundum type, and a patent ductus arteriosus.
