Patent Foramen Ovale More Condition_symptoms How Does One Know If They Have A Connection Between The Right & Left Sides Of The Heart (patent Foramen Oval)?

During fetal development, the inter-atrial septum develops, and finally the left atrium and the right to separate. The foramen ovale during fetal development remains open to allow venous blood to bypass the lungs and go into the systemic circulation. Since before the birth, the oxygen saturation of blood through the placenta and lung. A layer of tissue begins to cover the foramen ovale during fetal development, and then close completely after birth. Closes after birth, the pressure in the pulmonary circulation and the foramen ovale. Approximately 25% of adults in the foramen ovale does not seal over. ) In this case, increasing the pressure in the pulmonary circulation (eg pulmonary hypertension due to various causes, or only temporarily, during a cough may cause the opening of the foramen ovale. This is called a patent foramen ovale (PFO).
Foramen ovale usually does not, you can use the river to and from the lungs as an indirect connection. If I remember right, from Embryolgy, the foramen ovale normally closes Ebryonic development of the heart, if not, perhaps, paradoxical embolism. I do not think that a patent foramen ovale be heard on Auscutation.
