Was ist ein Atrium Septum Defekt?
Der Atriumseptumdefekt (ASD), Vorhofseptumdefekt (unübliche Abkürzung VSD) oder Vorhofscheidewanddefekt ist ein Loch in der Herzscheidewand zwischen den beiden Vorhöfen des Herzens (Septum interatriale). Er ist mit ca. 7,5 \% aller angeborenen Herzfehler die dritthäufigste angeborene Herzfehlbildung.
Wo ist das Vorhofseptum?
Das Vorhofseptum (Septum interatriale cordis) besteht aus einer relativ dünnen Wand und liegt zwischen dem rechten und linken Vorhof. Auf der posterioren Seite des Herzens zeichnet sich dieses Septum schwach sichtbar als Sulcus interatrialis ab.
How are the six types of atrial septal defects differentiated?
The six types of atrial septal defects are differentiated from each other by whether they involve other structures of the heart and how they are formed during the developmental process during early fetal development.
What are the possible complications of an uncorrected secundum atrioventricular ASD?
Complications of an uncorrected secundum ASD include pulmonary hypertension, right-sided heart failure, atrial fibrillation or flutter, stroke, and Eisenmenger’s syndrome . While pulmonary hypertension is unusual before 20 years of age, it is seen in 50\% of individuals above the age of 40.
What is the prevalence of mitral valve prolapse in ostium secundum ASD?
About 10 to 20\% of individuals with ostium secundum ASDs also have mitral valve prolapse. An ostium secundum ASD accompanied by an acquired mitral valve stenosis is called Lutembacher’s syndrome. Most individuals with an uncorrected secundum ASD do not have significant symptoms through early adulthood.
What is the function of the interatrial septum during pregnancy?
During development of the baby, the interatrial septum develops to separate the left and right atria. However, a hole in the septum called the foramen ovale, allows blood from the right atrium to enter the left atrium during fetal development.
