the american heart association guidelines have changed. only the people at the greatest risk for bad outcomes from infective endocarditis -- an infection of the heart valves -- should receive short-term preventive antibiotics before common routine dental and medical procedures. i generally request that patients have a screening by a cardiologist and a specific recommendation to go along with it.
i have a heart murmur and was told that pre-medication is no longer necessary before dental treatment. is this true?
