valve or in the tissues between the heart chambers.
Heart rhythm problems. Heart rhythm problems can occur if
the heart's electrical system has been damaged by the infection. This can cause

Blocked blood flow.
Endocarditis may produce blood clots (emboli) with infectious bacteria that can
break off (embolize) from where they originate and travel through the

Heart attacks are caused by complete blockage of blood flow to a part of the
Stroke. A stroke can occur if the blood
clot blocks blood flow in the arteries that lead to the brain.
oxygen because of blood clots in the lung. These blood clots can occur if the
endocarditis is in the right side of the heart.
