The latest trend in the medical profession is that of a refined open-heart surgery. In the days of old, doctors had to open a person's entire rib cage to get at the parts of the heart they needed access to. Well, this has just been changed drastically.
Surgeons can now perform the surgery without making large incisions.
In some cases, they don't even have to stop the heart like they did in the past. In this new method, which is called minimally invasive heart surgery, the doctors insert little cameras into the patient's body so that they can get all the angles that they used to. The only difference is that these cameras prevent the previous requirement that the entire chest cavity needed to be opened. By inserting these cameras, the images of the inner body are projected on monitors around the operating room so that the doctor can easily see what is going on. However, one other thing has to be done in order to have a successful operation.
