could you define "small in size"? We just had a 32 week ultrasound and have been told our boy has muscular VSD measuring 1.5mm.
Hi,
If the VSD is small in size and located in the muscular art of the interventricular septum (partition between the lower chambers of the heart), it usually closes spontaneously and especially in children below 2 yrs of age. Later on, such small VSD’s may not cause any significant problem with the exception of a risk of infection within the heart known as infective endocarditis. However, the closure can be done non-surgically also with the help of a catheter & an occluder in case you become symptomatic. I sincerely hope that helps. Take care.
