Atypical Complications of Huntington Chorea Disease

Foramen ovale, also called Foramen Botalli or Ostium Secundum of Born, is an anatomical interatrial communication which links the right atrium to the left atrium in the fetal heart. Histologically, it is a fibromuscolar flapping tissue which crescent in the limbus of the fossa ovalis. 

Following the birth, when there is an increased blood return to the left atrium because the lungs have expanded, the septum primum should normally closed against the left side of the limbus of the fossa ovalis. The Patent Foramen Ovale (PFO) is an atrial septal defect: It is one of the most common intra-cardiac anomaly. Its incidence is 10- 15% of the normal population and 27% of the autopsy. It was the first congenital cardiac defect to be repaired by using cardiopulmonary bypass. Read more>>>>>>>>>
