The Ancient Egyptians did not remove the heart during mummification. The liver, intestines, stomach and lungs were removed and kept in canopic jars. The brain was also removed, but discarded.
You've forgotten the ankh... A symbol for "life", and the eye of Horus which was the symbol of protection, good health and power. The scarab amulet was carried as a good luck symbol and also wrapped in the layers around a mummy.
