What is fossa oovalis?
Fossa ovalis is a structure located in the human heart. This structure, shallow depression, is formed in the right atrium just after birth. The formation of Fossa ovalis divides the heart into two parts, right and left. This allows the cardiovascular system to effectively distribute oxygenated blood throughout the body.
Before birth, the area that becomes fossa ovalis is open. This open structure, then known as foramen ovale, allows blood to flow freely from the right atrium of the embryonic heart to the left without passing through the lungs. Blood must bypass the lungs of the fetus because they are not used until birth and the blood received from the mother through the umbilical cord is already oxygenated.
During the first three months after birth, foramen ovale usually closes and becomes fossa ovalis. When the child uses his lungs, the pressure increases in the left atrium. This increased pressure is forced by foramen ovale. Complete closure may not occur until the child is two years old or in some cases not at all. This condition known as the patent foramen ovalE (PFO) may not cause any symptoms or problems for the patient. Many people do not even realize that they have PFOs unless the condition is detected by medical tests such as echocardiogram.
Incomplete formation of Fossa oovalis is unknown that it is a definitive cause of any health conditions or complications. However, some studies find correlation between this condition and the increased risk of stroke. Patients with Fossa ovalis opening can therefore receive aspirin therapy or treatment with other blood directors in an effort to prevent blood clots from exceeding the defect and minimize the risk of stroke.
Having a PFO can also cause patients to suffer from migraines. In particular, intense migraines, which are in patients with PFO, include vision of light aura as a symptom. The connection between PFO and migraines is stronger and better to improvePainted than the connection between PFOs and moves, because patients said their migraines stopped after they had surgery to repair defects in Fossa ovalis.
