How do you evaluate atrial septal defect?

For a suspected heart defect, your doctor might request one or more of the following tests:

1. Echocardiogram. This is the most commonly used test to diagnose an atrial septal defect.
2. Chest X-ray.
3. Electrocardiogram (ECG).
4. Cardiac catheterization.
5. MRI.
6. CT scan.

What is a secundum type atrial septal defect?

A secundum ASD is a hole in the middle of the septum. The hole lets blood flow from one side of the atria to the other. The direction depends on how much pressure is in the atria.

What is the difference between primum and secundum ASD?

Secundum ASD occurs in the middle part of the atrial septum. Primum ASD occurs in the lower part of the atrial septum close to the tricuspid and mitral valves. Sinus venosis occurs in the upper part of the atrial septum near the veins that drain into the right and left atrium.

What is ostium secundum?

The foramen secundum, or ostium secundum is a foramen in the septum primum, a precursor to the interatrial septum of the human heart. It is not the same as the foramen ovale, which is an opening in the septum secundum.

How many types of atrial septal defects are there?

There are five types of atrial septal defects ranging from most frequent to least: patent foramen ovale, ostium secundum defect, ostium primum defect, sinus venosus defect, and coronary sinus defect. Small atrial septal defects usually spontaneously close in childhood.

Can echo detect ASD?

A comprehensive echocardiogram includes evaluation of anatomical ASD characteristics, flow direction, associated abnormalities (eg, anomalous pulmonary veins), right ventricular anatomy and function, pulmonary pressures, and the pulmonary/systemic flow ratio.

What are the 3 types of atrial septal defects?

There are 3 major types of ASDs or interatrial communications: ostium secundum, ostium primum, and sinus venosus (Figure 1A) defects. The ostium secundum is a true defect of the atrial septum and involves the region of the fossa ovalis.

What are the 3 types of ASD?

The three types of ASD that will be discussed are:

• Autistic Disorder.
• Asperger’s Syndrome.
• Pervasive Development Disorder.

What is ASD in Echo?

Abstract. Atrial septal defect (ASD) is a common congenital abnormality that occurs in the form of ostium secundum, ostium primum, sinus venosus, and rarely, coronary sinus defects.

How are echocardiographs used to diagnose atrial septal defects?

Echocardiography is method of choice for assessment of patient with a known or suspected atrial septal defect. A Thorough knowledge and understanding of all echocardiographic view is essential for complete assessment of atrial septal defect , associated physiological status and assessment of neighbouring intracardiac structures.

Which is the most common atrial septal defect?

Ostium secundum (70%): defect located in the mid-portion of the interatrial septum Ostium primum (20%): defect located at the inferior portion of the inter-atrial septum (associated with a cleft mitral valve)

What are the parameters of an echocardiographic assessment?

Describe the echocardiographic parameters to characterize the normal interatrial septum and the abnormalities of atrial septal defect, atrial septal aneurysm, and patent foramen ovale. This will include the best practices for measurement and assessment techniques.
