Complications

In endocarditis, clumps made of germs and cell pieces form an abnormal mass in your heart. These clumps, called vegetations, can break loose and travel to your brain, lungs, abdominal organs, kidneys, or arms and legs.

As a result, endocarditis can cause several complications, including:

• Heart problems, such as heart murmur, heart valve damage and heart failure
• Stroke
• Pockets of collected pus (abscesses) that develop in the heart, brain, lungs and other organs
• Blood clot in a lung artery (pulmonary embolism)
• Kidney damage
• Enlarged spleen
