What is the difference between an atrial septal defect and a patent foramen ovale? - patent foramen ovale
a patent foremen ovale is a form of ASD. The foramen ovale is a hole between the two atria, which opens at the fetus in the womb. This allows the blood to be sent directly from the right heart will be to those without (which left no sense to the lungs in the womb, as they are,) only the oxygenation of the blood.
if the baby is born, blood preasure in the left atrium suggests that the foramen ovale slides closed. the definition of a patent foramen ovale, is when it is closed. Treatment is often surgical.
Other types of atrial septal defects, the other parts of the partition, but not on the closure of the open oval foramen. They are also surgical treatments, but are caused by other development issues.

Foramen ovale and atrial septal defect information
The most common type of atrial septal defect (80% of cases) is the persistence of the ostium secundum is the central partition, less frequently, the ostium primum (which is low in the septum), the mitral or tricuspid valve abnormalities may also be present. A third is the defect in the venous sinuses of the upper bulkhead. This is often associated with abnormal partial drainage of the pulmonary veins into the vena cava. In all cases, is usually oxygen-rich blood pressure via the left atrium into the right atrium, increasing the production of the right ventricle and pulmonary blood flow.
Although most people with a defect in the septum, relatively small amounts from left to right shunt left, people with moderate to severe shunts the risk of severe pulmonary hypertension is a result of irreversible pulmonary vascular disease. This can lead to Eisenmenger's syndrome, characterized by a straight left, and cyanosis. Atrial septal defects also predispose to atrialNone of the ostium secundum defect (see ECG). Primum defect incomplete or complete right bundle branch block is present in virtually all cases of atrial septal defect and indicated superior QRS ostium (see ECG available). With sinus-venous malformations, is the axis on the left side of P 15 degrees. The chest radiograph shows a large pulmonary artery, increased pulmonary vascular markings, an atrium and right ventricle is enlarged, and a small aortic knob.
The prognosis and treatment of the septum and the foramen ovale
Patients with small shunts can lead a normal life. Where the major cause of disability of 40 years. Raised pulmonary vascular resistance secondary to pulmonary hypertension is rare in childhood or adulthood in secundum defects but is more common in primum defects. After 40 years, pulmonary hypertension, cardiac arrhythmias (especially AF) and congestive heart failure May secundum defects occur. Paradoxical arterial embolization is a concern, especially in patients with pulmonary hypertension or venous thrombosis. Foramen ovaleis not associated with maneuvers, so they are asymptomatic. However, they are the lesion responsible for most of paradoxical emboli and are one of the most common causes of stroke. However, the risk of such events is relatively low, except in people with atrial septal aneurysm, requiring aggressive anticoagulation or closure of the defect. Infectious endocarditis not occur frequently.
Small atrial septal defects do not require surgery. The risks are now so low that patients with too right shunt and pulmonary and systemic flow ratio from 1.5 to 2.0 then the attacker can exploit the left, if the overall picture mandates clinic. Ratios above 2.0 are an indication for the surgical closure of the lesion.
Transcatheter techniques are now widely used for the closure of atrial septal defects and patent foramen ovale. These include the use of an umbrella-like device from a position of blocking the femoral vein. The device is most effective in patients with central secundum defects.
Shou SurgeryLD is investing in patients with pulmonary hypertension with right (left) shunting (Eisenmenger syndrome) abandoned because the risk of acute right heart failure. Removal of the pulmonary veins in patients with partial anomalous venous drainage. In ostium primum defects, and the closure of the defect, cracks in the seam of the mitral valve, the valve is especially recommended if the degree of significant mitral regurgitation is present. The rate of operative mortality is low (\\ \\ \\ \\ \\ \\ \\ \\ u0026lt, 1%) in patients under age 45 who do not have heart failure and those with pulmonary arterial systolic blood pressure u0026lt \\; 60 mmHg. Increase of 5-10% in 40 patients with heart failure or pulmonary arterial systolic pressure above 60 mmHg.
