**Question:** True about V.S.D. is, all except
A. Ventricular septal defect (VSD) is a congenital heart defect where there is a hole in the wall (septum) separating the ventricles (lower chambers) of the heart.
B. VSD can be either muscular or membranous, depending on the type of septum affected.
C. VSD is a rare condition with a prevalence of around 1 in 1000 live births.
D. VSD can be closed surgically, using a heart catheterization procedure.
**Correct Answer:** D. Ventricular septal defect can be closed surgically, using a heart catheterization procedure.
**Explanation:**
Ventricular septal defect (VSD) is a congenital heart defect where there is a hole in the wall (septum) separating the ventricles (lower chambers) of the heart. This separation is essential for proper circulation as it ensures that oxygen-rich blood from the lungs is directed to the left ventricle and oxygen-poor blood from the rest of the body is directed to the right ventricle.
VSD can be either muscular or membranous, depending on the type of septum affected. Muscular VSD occurs when the wall between the ventricles is made up of a layer of muscle tissue, and membranous VSD occurs when the wall is made up of a layer of membrane-like tissue.
VSD is a relatively common congenital heart defect, with a prevalence of around 1 in 1000 live births. However, the question provided asks about a specific aspect of the condition, specifically the surgical closure of the defect.
While the correct answer is D, which explains that VSD can be closed surgically using a heart catheterization procedure, the other options are important to understand as well:
A. VSD is a congenital defect, which means it is present at birth and is not acquired later in life.
B. VSD can be managed conservatively, meaning without surgical intervention, by prescribing medications like diuretics to manage symptoms like congestive heart failure.
C. The prevalence of VSD in live births indicates its relatively common occurrence, but does not address the surgical closure methods.
In summary, while knowing that VSD can be closed surgically using a heart catheterization procedure is essential, understanding the nature of the defect, management options, and its prevalence also plays a crucial role in grasping the concept thoroughly.
