CTICasesProsthetic Valve Endocarditis
Imaging findings
CT chest and echocardiogram show a massive, mobile, lobulated soft-tissue mass (vegetation) measuring several centimeters anchored to a prosthetic cardiac valve, in a patient with a remote history of drug use.
Key takeaways
Prosthetic valve endocarditis is a severe, high-mortality infection. Vegetations can grow to massive sizes on prosthetic material, presenting on gated cardiac CT as large mobile filling defects that can cause valvular dysfunction, embolization, or heart failure.
