Hi cheryl, my little girl had large bilateral choroid plexus cysts. Needless to say I worked myself into a panic for sometime but she is a beautiful healthy little girl. The cysts are often found in babies without any genetic abnormalaties and resolve on their own. A lot of literature suggests not telling parents as they are generally not a problem and just cause the parent worry.

As for the heart it may just have been the position te baby was in that made it hard to visulise the septum. If they can see four chambers it is present, they like to have a good look at it to see that it is whole.

Good luck with the anomaly scan, just think of it as another chance to see your bubs
