Echocardiography

Echocardiography is used in the diagnosis of MRSA endocarditis. The findings on an ECHO include:

• Irregular echogenic mass attached to valve leaflet
• Large vegetations occur with staph. aureus endocarditis.
• The hemodynamic effects are mostly due to valvular regurgitation as a result of valve destruction.

The minimum size of a vegetation that is identifiable on trans thoracic echocardiography is 3 mm and by transoesophageal echocardiography route is 2 mm.
