Causes

Endocarditis can involve the heart muscle, heart valves, or lining of the heart. Most people who develop endocarditis have heart disease of the valves.

Risk factors for developing endocarditis include:

  • Injection drug use
  • Permanent central venous access lines
  • Prior valve surgery
  • Recent dental surgery
  • Weakened valves

Bacterial infection is the most common source of endocarditis. However, it can also be caused by fungi. In some cases, no cause can be identified.
