I am a proffessional firefighter and had AVR surgury 4 weeks ago . I choose a Saint Jude valve knowing I would have to be on coumadin for life. I am hearing that I will not be allowed to do my job even after I am through rehab, because of the anticoagulant . My surgeon and cardiologist say I will e fine to go back to work but the city says not on coumadin. Any other police or firemen with valve replacement out there? Did you go back to full duty? How careful do you have to be on coumadin? Is this going overboard by the city ? I know there are NFPA rules in place but they don't make allot of sense given the advances in medicine these days. Any input is appreciated.
