A member asked:

I'm aware this guy who has a hole in his heart and he's gonna have to have surgery. what's gonna actually happen to him?

It depends: The operations vary depending on where the hole is and what other problems the patient might have. Usually, the hole is closed. This is usually done by covering it with a patch, but not always. To do this, blood has to be rerouted away from the heart and lungs to the cardiopulmonary bypass machine, which pumps blood and exchanges gases like oxygen and carbon dioxide.
