Systemic Shunts ( AtrioVentricular shunts in case of Dialysis if infected)
Prosthetic Joints ( like Knee and Hip Replacements)
Artificial heart valves.
A history of an infection of the lining of the heart or heart valves known as infective endocarditis.
A heart transplant in which a problem develops with one of the valves inside the heart.
Cardiomyopathy
Mitral Valve Prolapse with Regurgitation
Stents placed with Angioplasty if cardiologist recommends
Heart conditions that are present from birth, such as:

• Unrepaired cyanotic congenital heart disease, including people with palliative shunts and conduit.
• Defects repaired with a prosthetic material or device whether placed by surgery or catheter intervention during the first six months after repair.
• Cases in which a heart defect has been repaired, but a residual defect remains at the site or adjacent to the site of the prosthetic patch or prosthetic device used for the repair.
• Antibiotic prophylaxis guidelines also have been developed for people who have orthopedic implants such as artificial joints. In 2012, the ADA and American Association of Orthopedic Surgeons updated the recommendations and no longer recommend antibiotics for everyone with artificial joints. As a result, your healthcare provider may rely more on your personal medical history to determine when antibiotics are appropriate for people with orthopedic implants. For example, antibiotic prophylaxis might be useful for patients who also have compromised immune systems (due to, for instance, diabetes, rheumatoid arthritis, cancer, chemotherapy, and chronic steroid use), which increases the risk of orthopedic implant infection. If you have a heart condition or an orthopedic implant, talk with your dentist or physician about whether antibiotic prophylaxis before dental treatment is right for you.
