VENTRICULAR SEPTAL DEFECT
ventricular septal defect (VSD) is a birth defect of the heart in which there is a hole in the wall (septum) that separates the two lower chambers (ventricles) of the heart.
This wall also is called the ventricular septum.
A ventricular septal defect happens during pregnancy if the wall that forms between the two ventricles does not fully develop, leaving a hole.
A ventricular septal defect is one type of congenital heart defect. Congenital means present at birth.
An infant with a ventricular septal defect can have one or more holes in different places of the septum. There are several names for these holes.
Some common locations and names are (see
- Conoventricular Ventricular Septal Defect
In general, this is a hole where portions of the ventricular septum should meet just below the pulmonary and aortic valves.
- Perimembranous Ventricular Septal Defect
This is a hole in the upper section of the ventricular septum.
- Inlet Ventricular Septal Defect
This is a hole in the septum near to where the blood enters the ventricles through the tricuspid and mitral valves. This type of ventricular septal defect also might be part
- of another heart defect called an atrioventricular septal defect (AVSD).
- Muscular Ventricular Septal Defect
This is a hole in the lower, muscular part of the ventricular septum and is the most common type of ventricular septal defect.
A ventricular septal defect usually is diagnosed after a baby is born.
- Shortness of breath,
- Fast or heavy breathing,
- Tiredness while feeding, or
- Poor weight gain.
