Ventricular Septal Defect
Also written as: VSD — Ventricular Septal Defect
A congenital heart defect characterized by an abnormal opening in the wall separating the heart's two lower chambers.
Full Definition
Ventricular septal defect (VSD) is the most common type of congenital heart defect, occurring when there is a hole in the ventricular septum that allows blood to flow from the left ventricle to the right ventricle. This condition can range from small defects that may close spontaneously to large defects requiring surgical intervention. VSDs are classified by location within the septum and can lead to increased pulmonary blood flow and potential complications if left untreated. The condition may be isolated or associated with other congenital heart abnormalities.
Usage
