I was born with a small hole in my heart could i have out grown it how would i know if i didn't ?

VSD: Many people outgrow a ventricular septal defect (which i bet is what you are describing) during childhood as the muscle develops and occludes the hole. However, ignoring a vsd that remains in place is very dangerous. A physician needs to follow you closely and advise about need for surgery and/or infection prevention.

Usually so: Technically, everyone is born with a "hole in their heart" between the upper chambers (atria) called a patent foramen ovale (pfo). This closes gradually over time, but in 1-in-7 people it never closes completely. Holes between the lower chambers (ventricular septal defects or vsds) can also close over time. A vsd makes a murmur your doctor can hear. A PFO does not but testing is rarely needed.

ECHO: If it was a small muscular type of ventricular septal defect usually are asymptomatic and spontaneously close with time. An echocardiogram or transesophageal echocardiogram can show if there is any resudual vsd. A small ASD will not close. A patent foramen ovale may close or become probe patent only.
