The cause is a failure of closure of the ostium secundum and the result is a persistent communication between the right and left circulations at atrial level. The commonest form of this defect (so called Secundum ASD) is a defect in the central part of the "Atrial Septum" (the partition separating the Atriums). This allows red blood to pass through into the right side of the heart, leading to enlargement of the right ventricle and excessive flow in the lung circulation. A sinus venosus ASD is a type of atrial septum defect in which the defect involves the venous inflow of either the superior vena cava or the inferior vena cava. [citation needed] A sinus venosus ASD that involves the superior vena cava makes up 2 to 3% of all interatrial communication.

In this report, we present the case of a 20-year-old female patient diagnosed with Eisenmenger syndrome secondary to a large secundum ASD. The patient responded well to medical treatment. This is a cardiology VIDEO presenting a case of a secundum atrial septal defect (ASD). The findings in the ECG, chest X-ray, transthoracic echocardiography (TTE), 2-D and 3-D transesophageal echocardiography (TEE) are shown and explained in this cardiology video. 2017-05-01 An atrial septal defect (ASD) is an opening in the interatrial septum, causing a left-to-right shunt and volume overload of the right atrium and right ventricle. Children are rarely symptomatic, but long-term complications after age 20 years include pulmonary hypertension, heart failure, and atrial arrhythmias.

These may be classified as: Patent foramen ovale.

Device closure is frequently performed for secundum ASD, depending on the size of the defect and the weight of the child. During the cardiac catheterization procedure, the child is sedated and a small, thin, flexible tube (catheter) is inserted into a blood vessel in the groin and guided to the inside of the heart.

Spontaneous closure reported in secundum ASD within the first year of life. An initial chest X-ray (Figure 1) was suggestive of a significant left to right shunt with In contrast to primum or secundum atrial septal defects, IVC-ASD do not secundum ASD. 60-90% of all ASDs; usually an isolated abnormality · primum ASD. 5-20%; associated with cleft anterior mitral valve leaflet (partial atrioventricular Feb 6, 2019 Most radiologists will interpret multidetector chest CT and should be a Large ostium secundum ASD (black arrow) in a 51-year old female An atrial septal defect (ASD) is an abnormal hole in this wall.

This type of ASD is a true deficiency of the interatrial septum and is distinct from the frequently identified patent foramen ovale. Best visualized on subcostal four-chamber view of the heart. Ostium secundum ASD's appear as a larger than expected area of dropout in the central portion of the septum secundum (in the vicinity of the foramen ovale) or as a deficient foraminal flap (septum primum) that fails to cover the entire foramen ovale. Atrial septal defects (ASDs) can be classified as morphologic defects of the interatrial septum that directly communicate the right and left atria (ostium primum ASD, endocardial cushion defects, ostium secundum ASD) and as defects that do not involve the interatrial septum but physiologically behave like interatrial septal defects (sinus venosus ASD, unroofed coronary sinus). Förmaksseptumdefekt (ASD-secundum; secundum atrial septal defect) är ett medfött hjärtfel som består i en defekt i förmaksskiljeväggen.

The most common type of ASD, the ostium secundum ASD, generally occurs in isolation. It is located centrally in the atrial septum, superimposed on the fossa ovalis. The ostium primum ASD is the second most common type. An ASD is characterized by a defect in the interatrial septum that allows pulmonary venous return to pass from the left to the right atrium (i.e., left-to-right shunt), resulting in right atrial and right ventricular chamber dilation. There are four types of ASD. The first type is an ostium secundum defect. A more robust method for demonstrating a secundum ASD is to acquire phase-contrast images parallel to the septum at the level of the fossa ovalis.

With either type of ASD, ASD will usually cause the blood flow from the right atrium to skip going to the right ventricle and instead flow to the left atrium.
