About my husbands bad mitral valve,doctor,symptoms prophylactic meds.?

my hubby, is 55 who needs a mitral valve.. queston: this was his second echo.first was done 5 yrs ago. i ask art(hubby)the next Dr. visit,"how was the test?" Ok i guess Dr. didn't say anything? 3 mths later,We WE WENT TO drs. I asked dr.about test(.answer): What test? To make this shorter, not get hopping mad again.we were sent to the cardiologists in 4days, results. Needs new valve.He now has"servere" mitral valve disease.
I'd like a new internest.wouldn't you? this last echo shouldn't have been missed.
should he be on asprin therapy until surgery?
cardio said he has calcium builup on valves & thinks he was born with 2 mitral flaps not 3.
cardo said lets wait till he gets more symtoms?
Art is always sleeping..at the least 10 to 12 at night and 1, 2naps. Has different
pressures in his arms. no chest pain, pressure.
his heart is VERY loud.can he have heart attack at any time
question: Mechanicl or pig valve.why?
me"respiratory" life suports
advise:of other potential symps?

I had a friend with the same problem. She was born with 2 instead of 3 valves. Not sure of exactly what happened. I urge you not to take this condition lightly. Have your hubby to stay away from any form of caffeine or chocolate. These ingrediends cause the heart to flutter. Also have the doctors to check him for blood clots. This is what took my friends life. Just to be on the safe side. But, lately I have heard of quite a few people with this problem either had blood clots all along or got them. Make sure his physician(s) are aware of his sleeping habbits. I'm not trying to scare you. I'm just trying to prevent you from losing your loved one as I have.

Good Luck
