Fossa ovalis (heart) The fossa ovalis is a depression in the right atrium of the heart, If the atrial septum does not close properly, it leads to a patent foramen ovale. Structure Heart section showing ventricles and ventricular septum Ventricles.
108 CHAPTER 6 Cardiovascular System Atrial and ventricular septal defects occur when there is an undesired opening in the septum connecting the right and left sides of the heart, allowing for the mixing of oxygenated and deoxygenated blood. When the foramen ovale fails to close properly, it is commonly referred to as a patent foramen ovale (PFO).
