Question

Which of the following statements is NOT correct?

Select one:

a. Septal defects are common congenital abnormalities

b. Ventricular septal defects are more common than atrial septal defects

c. Cyanosis is typically present in ventricular septal defects

d. Septal defects refer to a hole in the septum separating the left and right sides of the heart

e. Around one quarter of small septal defects close spontaneously during infancy

Answer 1

Answer is option- C - Cyanosis is typically present in ventricular septal defects

Ventricular septal defect is usually symptomless at birth. VSD is an acyanotic congenital heart defect, so there are no signs of cyanosis in the early stage.

Septal defect are mainly two type , Atrial septal defect and ventricular septal defect. These are most common congenital abnormality of the heart.

Atrial septal defects (ASD) are located between the heart's upper chambers (atria), which receive blood from the body. Ventricular septal defects (VSD) are located between the lower chambers (ventricles), which pump blood to the body.

spetal defect is the hole (defect) occurs in the wall (septum) that separates the heart's lower chambers (ventricles) and allows blood to pass from the left to the right side of the heart.

VSD for 20% and ASD for 10%. of the congenital abnormality of heart disease

most common congenital heart defects. Most of the small or moderate size (<6 mm) muscular VSDs close spontaneously within the first two years of life
