Patient's Query

Hello doctor,

My baby was diagnosed with 4 mm VSD during the 20th week of pregnancy. After delivery, an echocardiogram was done, and our pediatric cardiologist told me that my baby had large perimembranous VSD shunting bidirectionally. But did not tell us the size. My baby is three months old now. I wish to know whether size matters in VSD or not. My baby has poor weight gain. So cardiologist told us to prepare for surgery. Currently, he is on Furosemide 0.2 ml twice a day.

Hello,

Welcome to icliniq.com.

Yes, size matters small VSDs (ventricular septal defect) do not require treatment, while large ones (usually more than 6 mm of the size of the aorta) need surgical correction only. So here it is being large and has no significant gradient across it, so it needs surgical correction. So here, whether it is 8 mm, 10 mm or 12 mm, or some other size, management remains the same. So relatively, size is not important here.

Same symptoms don't mean you have the same problem. Consult a doctor now!
