Went for my 6 month teeth cleaning and the dentist said "American Heart Association said no cleaning or elective procedures, only emergencies during the first year after open heart surgery".......has anyone else had this happen?? Never heard of it. My cardiologist must of not known since she said that I wouldn't need antibiotics for cleaning.:confused2:

Laura - There is a very good reason for the majority vote here: the Consensus Guidelines (AHA/ACC/ADA) dispute both your dentist and cardiologist. Here are the AHA Guidelines for Prevention of Endocarditis:
http://circ.ahajournals.org/content/116/15/1736.full.pdf as well as the same incorporated into the ACC Valve Disease Guidelines:
http://content.onlinejacc.org/cgi/reprint/52/13/e1.pdf. The changes made in 2007 are more than a little controversial, particularly the recommendation that those with native valve disorders (such as BAV) no longer need to premedicate, but the consensus recommendation still stands that prophylactic antibiotics should be used for anyone with a prosthetic heart valve for
most "disruptive" dental procedures (the Guidelines do list some exclusions for less risky procedures such as removable appliances). Now, it's still not definitively proven that this is the best medical decision, but based on the limited amount of available evidence, the experts in the field agree it's the most "reasonable" recommendation to make.
Anyway, moving on, as for the 6 month or 12 month waiting period, that usually stems from the endothelialization (not nearly this simple but basically tissue overgrowth) period of the valve replacement, specifically things such as the sewing cuff and sutures which are prone to short term infection until full endothelialization takes place. Normally, that happens within a 3 to 6 month period of time, though. Now, not that this means anything, but I do actually remember reading one isolated recommmendation somewhere, I think maybe a surgeon in a valve related webchat, to wait 12 month, but by no means is that common practice. The general consensus has always seemed to be 6 months (which of course matches up in schedule with a recommended pre-surgery visit), and I don't think I've ever seen a 12 month waiting period in any AHA guidelines. Maybe your dentist would like to share his source? :confused2:
