septal defect

Etymology: L, saeptum, fence, defectus, failure
a defect in the wall separating the left and right sides of the heart. Depending on the size and the site of the defect, various amounts of oxygenated and deoxygenated blood mix, causing a decrease in the amount of oxygen carried in the blood to the peripheral tissues. The defect is usually congenital. Kinds of septal defects are atrial septal defect and ventricular septal defect.

septal defect

An abnormal opening in the central wall of the heart providing a communication from the right side to the left or vice versa. This is a developmental congenital defect and its significance varies from trivial to grave depending on its position and size. Popularly known as ‘hole in the heart’.

positive defect
in neurology, an involuntary movement, such as tremors, abnormal posture or seizures.

Three of these occur frequently enough to be considered part of the anomaly: ventricular septal defect in approximately two thirds of patients (2); left ventricular (pulmonary ventricular) outflow tract obstruction, which can be valvular and/or subvalvular, in one half (1); and anatomic abnormalities of the tricuspid (systemic atrioventricular) valve in 90%, many of which are not clinically significant and the most common of which is Ebstein's anomaly (2).
For example, closure of the ventricular septum occurs by 6 weeks post conception, so an exposure that causes a ventricular septal defect (VSD) must occur before 6 weeks.
