Importance of Fossa Ovalis
The foramen ovale before birth allows the oxygenated blood that enters the right atrium through the inferior vena cava, to enter the left atrium, and to clog the flow back the opposite way, through the way of valve. Due to this function of foramen ovale the heart doesn’t work hard to pump blood where it is not needed.
The location of the fossa ovalis is required for a number of significant surgical procedures. Patent foramen ovale and atrial septal defect repair, Right heart catheterization, Percutaneous balloon valvuloplasty, Radiofrequency catheter ablation, Pulmonary vein isolation, Left atrial appendage closure, Catheter-based mitral valve repair, Hemodynamic assessment of the mitral valve, Paravalvular leak closure are few surgical procedures that require the position of fossa ovalis.
Fossa Ovalis
The heart is a muscular organ that circulates blood through the circulatory/vascular systems around the body. It assists in the distribution of oxygen to every region of the body. The heart is shaped like a quadrangular pyramid, with the anterior thoracic wall at its apex and the posterior thoracic wall at its base. It is split into two halves by a septum or partition. Four chambers are created by further dividing these sections. It is situated in the middle of the mediastinum and is surrounded by the pericardium, a two-layered sac filled with fluid. Electrical impulses generated by this muscle cause the heart to beat and pump blood throughout the body. The large blood vessels that branch out from the heart supply blood to the upper and lower limbs, thorax, and belly. The cardiovascular system of the body is made up of the heart and the circulatory system.
