Nervous about level 2 scan

At my anatomy scan they saw something with the heart that they want to look at on a higher level u/s. I'm nervous that the baby will have some kind of heart defect. I go tomorrow to a hospital that actually had the equipment for the scan. The only bright side (other then hopefully hearing everything looks OK or at least nothing's serious) is they couldn't tell the gender at my anatomy scan so I'm holding my breath and crossing my toes that they can tell this time. Otherwise its going to be a long wait until another scan.
