Usual types of ASD are the commonest ostium secundum ASD and the less common varieties of ostium primum ASD and sinus venosus ASD. Sinus venosus ASD can be subdivided into superior vena cava type and inferior vena cava type.
An ostium secundum atrial septal defect is a type of congenital heart defect called an atrial septal defect (ASD). An ASD is a hole in the wall (septum) between the two upper chambers of the heart (the atria). ASDs can be classified by location. An ostium secundum ASD is a hole in the center of the atrial septum. The ostium secundum atrial septal defect is the most common type of atrial septal defect and comprises 6–10% of all congenital heart diseases. [ citation needed ] The secundum atrial septal defect usually arises from an enlarged foramen ovale , inadequate growth of the septum secundum , or excessive absorption of the septum primum .
The most common type of ASD (accounting for 50-70% of all cases) is known as ostium secundum defect, or simply, secundum (2). In this case, the hole is located near the center of the atrial septum. Atrial septal defect is classified according to the area of the septum in which it is located. In general, its anatomical forms are: Ostium secundum: they are the most common type of ASD, constituting 80% of the cases. It is located in the area of the fossa ovalis. Sinus venosus: they comprise 5% of ASD. They are locatedin the superior or Background Atrial septal defect (ASD) is one of the more commonly recognized congenital cardiac anomalies presenting in adulthood. ASD is characterized by a defect in the interatrial septum The most characteristic feature of an atrial septal defect is the fixed split S2. As mentioned in the murmur overview, a split S2 is caused physiologically during inspiration because the increase in venous return overloads the right ventricle and delays the closure of the pulmonary valve.

The normal atrial septum (panel A) as well as various types of atrial septal defects (ASD) are shown. Panel B: secundum ASD is formed by the poor growth of the
These ASDs are called septum secundum ASDs. The two other types of ASDs are septum primum ASDs and sinus vensosus ASD, together account for just 10 %
Types: • Secundum ASD (50-70%): This most common type is located in the upper, thicker part of the septum. Most close spontaneously without intervention.

Importantly, the high ostium secundum. ASD is not associated with anomalous pulmonary venous return.
An ostium secundum ASD is a hole in the center of the atrial septum. The ostium secundum atrial septal defect is the most common type of atrial septal defect and comprises 6–10% of all congenital heart diseases. [ citation needed ] The secundum atrial septal defect usually arises from an enlarged foramen ovale , inadequate growth of the septum secundum , or excessive absorption of the septum primum . An atrial septal defect of the secundum type is relatively common and occurs from failure of the septum secundum to develop.

The presence of an ostium secundum-type ASD or PFO was identified by ICD-9 diagnosis code 745.5. The primary study outcome was perioperative acute ischemic stroke. Between 2004 and 2014, there were 639,985 admissions for noncardiac surgery with an in-hospital echocardiogram. An ASD or PFO was documented in 9,041 (1.4%) hospitalizations.
Se hela listan på de.wikipedia.org What are the Different Types of ASD? There are three common types of atrial septal defect (ASD): Ostium Secundum - located in the center of the atrial septum (most common type) Ostium Primum - located near the lower portion of the atrial septum, may be associated with defects in the mitral and tricuspid valve (second most common type) Secundum ASD is by far the most common of the atrial septal defects, accounting for greater than 80% of all atrial defects where the specific sub-type is identified. Secundum ASD is ~ 6 times more common than the ostium primum ty pe ASD (1.7 per 10,000 live births) and ~ 25 www.intechopen.com Our series of patients with ASD by transcatheter occlusion shows that the procedure is safe and effective in the vast majority of cases. To further reduce the complications rate, the criteria of device selection according to ASD morphology and some technical tips during implantation are discussed. Atrial Septal Defect.

7 Oct 2016 Methods: From April 2011 to January 2012, 30 patients with secundum type ASD were treated by transcatheter closure of their defects.
het ostium primum defect. A few studies evaluating ECG variables among patients with secundum-type ASD have demonstrated an increase in P-wave dispersion. After comparing 62 patients with secundum-type ASD and 47 healthy individuals, it was reported thatP maximum, P minimum, andPdispersion times were prolonged for patients with secundum-type ASD due to mechanical and electrical changes in the atrial myocardium.

Grundsätzlich besteht bei asymptomatischen Patienten mit einem Shunt-Volumen <40% keine Therapieindikation.
