Q

What’s the difference between endocarditis and myocarditis/ Pericarditis?

A

Endocarditis is inflammation of the inner walls of the heart. Caused most often by valvular repair and surgery. Look for peds with CHD’s receiving surgery. Bacterial.

Myocarditis/pericarditis is caused by a viral infection.
