Seven months pregnant, the fetus was found to have a ventricular septal defect of 2.5mm.

Patient's question:

No

Doctor's answer:

A simple ventricular septal defect does not affect the blood circulation of the fetus, meaning there are no issues with nutritional supply. Moreover, over 90% of small defects can naturally close within the first year of life. Large defects may lead to heart failure requiring treatment within 2 to 8 weeks after birth. Only a small number of extremely large ventricular septal defects can cause immediate heart failure upon birth. The surgical survival rate is over 90%, and postoperative physical endurance is normal, meaning it is the same as in healthy individuals.
