There are a few ways in which the pulmonary artery might not work properly.

* It leaks - in which case you would probably die (slowly if it were a simple leak, or quickly if it fully ruptured) without surgical care. (Very rare) * It is clogged with a clot - which would probably dislodge and move to the lungs. (Very dangerous, fairly common.) * It doesn't constrict or open properly - would lead to congestive heart failure. (Very common) There are other issues a person may have, and under competent medical care, each of the above can be treated.
