Atrioventricular septal defect (AVSD) is characterized by a deficiency of the atrioventricular septum of the heart. It is caused by an abnormal or inadequate fusion of the superior and inferior endocardial cushions with the mid portion of the atrial septum and the muscular portion of the ventricular septum. The following codes are used with International Statistical Classification of Diseases and Related Health Problems. ... The following is a list of codes for International Statistical Classification of Diseases and Related Health Problems. ... The heart and lungs (from an older edition of Grays Anatomy) The heart (Latin cor) is a hollow, muscular organ that pumps blood through the blood vessels by repeated, rhythmic contractions. ... The interatrial septum is the wall of tissue that separates the right and left atria of the heart. ... Interventricular septum: The stout wall separating the lower chambers (the ventricles) of the heart from one another. ...
If there is a defect in this septum, it is possible for blood to travel from the left side of the heart to the right side of the heart, or the other way around. Since the right side of the heart contains venous blood with a low oxygen content, and the left side of the heart contains arterial blood with a high oxygen content, it is beneficial to prevent any communication between the two sides of the heart and prevent the blood from the two sides of the heart from mixing with each other.
VSDs can be detected by cardiac auscultation, they cause atypical murmurs and loud heart tones. Confirmation of findings from cardiac auscultation can be obtained with a cardiac ultrasound (echocardiography) (less invasive) and cardiac catheterization (more invasive). Auscultation is the technical term for listening to the internal sounds of the body, usually using a stethoscope. ... Medical ultrasonography (sonography) is an ultrasound-based diagnostic imaging technique used to visualize internal organs, their size, structure and any pathological lesions. ... An echocardiogram. ... Cardiac catheterization (heart cath) is the insertion of a catheter into a chamber or vessel of the heart. ...
Treatment is surgical. Open surgical procedures require a heart-lung machine and are done with a median sternotomy. Percutaneous endovascular procedures are less invasive and can be done on a beating heart, but are only suitable for certain patients. A cardiac pump or cardiac bypass pump or heart-lung machine temporarily takes over the function of breathing and pumping blood for a patient. ... Median sternotomy is a surgical procedure in which a vertical inline incision is made along the sternum, after which the sternum itself is divided, or cracked. This procedure provides access to the heart and lungs for surgical procedures such as heart transplant, corrective surgery for congenital heart defects (CHDs... In surgery, percutaneous pertains to any medical procedure where access to inner organs or other tissue is done via needle-puncture of the skin, rather than by using an open approach where inner organs or tissue are exposed (typically with the use of a scalpel). ...

Atrioventricularseptaldefects represent a spectrum of lesions that are associated with maldevelopment of the atrioventricular septum and adjoining atrioventricular valves.
The most complex combination is that of a defect of the atrial portion on the atrioventricular septum, a nonrestrictive ventricular septaldefect, and complex morphology of the atrioventricular valves.
Unbalanced atrioventricularseptaldefect refers to the situation in which the two atrioventricular valves (or the common atrioventricular valve) overrides the ventricular septum to an such an extent that one of the ventricles is well developed (most commonly the left), and the other ventricle is hypoplastic.
