Dear Light, the open oval window (Open Company) is located in an interatrial septum (a septum between the right and left auricle (auricles - two top chambers of heart). In norm or rate it is closed right after birthes. Sometimes Open Company is closed later. If it or this does not occur or happen, functioning of Open Company, as a rule, do not frame vital issues. In opinion of different authors, about 20 % of people live from Open Company all life. But problems can arise in that case when the size of a window is great and is available expressed sbrom from left in the right auricle. So, the forecast in your case depends on the size of a window and size of dump through it or him.
