I have a history of congenital heart disease, am i more susceptible to getting endocarditis?

Depends on defect: Some types of congenital heart disease increase one's risk for infectious endocarditis more than other types. Congenital heart defects that raise the risk for endocarditis include: bicuspid aortic valve, patent ductus arteriosus, ventricular septal defect, coarctation of the aorta, and tetralogy of Fallot.

It depends: Depending on what condition you have and if you have had any surgical correction and how recent some of these repairs may make you more prone to a heart valve infection. Check with your doctor.
