Bicuspid aortic valve and MRSA
MRSA (Methicillin Resistent Staphylococcus Aureus) endocarditis can destroy heart valves, especially ones that are abnormal such as a bicuspid valve or prosthetic valves. If the infection damages a heart valve, sometimes surgery is needed. However, a decision to operate on a heart valve depends on complications caused by the malfunction. The decision to operate on a damaged valve is depended on a lot of factors that especially include evidence the valve is involved and heart failure. Sometimes the infection can be managed by antibiotics alone.
In a patient with MRSA there certainly would be a concern that a heart valve is or will become involved. Tests (often many times repeated) include blood cultures for MRSA and cardiac ECHOS. Regarding your question, I have never seen a MRSA infected valve without lots of related abnormalities.
Hope this helps,
