Disadvantages:
Rejection
Antigens on the surfaces of cells in animal organs are drastically different from human antigens, rendering them very easily recognized and targeted by the immune system, leading to organ necrosis and rejection. This rejection may be mitigated by immunosuppressants but this would mean that the patient will have to take immunosuppressant drugs for the rest of their lives and live with an increased risk for infections due to immunosuppression.
Physiological differences between species
Physiological differences between humans and the animal species means that the animal organ may not be designed to perform the same function that it does in humans or it performs the function to a different extent.
Disease
Certain diseases can cross the species barrier and infect the patient if the animal organ is not appropriately chosen.
Ethical
Certain patients may not wish to have animal organ transplants for religious, animal rights or other psychological concerns.
Advantages:
Availability
Animal organs, especially those from domesticated species (sheep, pig, dog, etc.) are easily accessible as these animals are easy to breed and their anatomies are well understood.
Cost
While no cost can be assigned to a human organ, an animal organ can be bought or sold at a price proportional to the animal's economic value.
Ethical
Animal transplantation is more justifiable than human organ trade.

Generally they're not used, since animal organs are not similar to human organs, so are not suitable for maintaining function within the human body. In very rare circumstances they are used to try and bridge a gap until a human organ becomes available. They are never used as a long term solution (because they do not work long term). Whether they should be used or not is practically irrelevant, since they cannot be used as a long term solution.
