15 The septum primum becomes contiguous with the systemic venous tributaries to form the inflow of the superior and inferior vena cavae. A) It is measured in mm Hg. Before birth, the fetal circulation directs oxygen-rich blood returning from the placenta to mix with blood from the hepatic veins in the inferior vena cava. In 106 patients (54%), ASA was associated with interatrial shunting (atrial septal defect, n=38; patent foramen ovale, n=65; sinus venosus defect, n=3). Before describing the TP procedure, it is of utmost importance to become familiar with IS anatomy. At birth, a small flap of tissue moves to cover the foramen ovale and prevent the flow of blood between the atria. The foramen ovale is continuous with the ostium secundum, again providing for continued shunting of blood. Welcome to Anatomy of Heart Quiz! Before describing the TP procedure, it is of utmost importance to become familiar with IS anatomy. As judged from TEE, ASA involved the entire septum in 100 patients (51%) and was limited to the fossa ovalis in 95 (49%).

Pas na nieuwe vondsten uit 1964 door John Ostrom kreeg het dier zijn naam, Normally in an adult heart, the interatrial septum bears an oval-shaped depression known as the fossa ovalis, a remnant of an opening in the fetal heart known as the foramen ovale. 15 The septum primum becomes contiguous with the systemic venous tributaries to form the inflow of the superior and inferior vena cavae. Foramen ovale: anatomic opening between the right and left atrium. interatrial septum. The flap of the foramen ovale is termed the fossa ovalis and is formed by the septum secundum, septum primum (which attaches on the left atrial [LA] side of the septum secundum), and the AV canal septum. The heart is charged with the sole function of pumping blood throughout the body and, in so doing, ensuring nutrients can be transported with ease.
