Isolated Pulmonary Valve Endocarditis.

Endocarditis of only the pulmonary valve is a very rare finding and is often missed during echocardiographic evaluation due to limited views of the pulmonary valve and a low index of suspicion. We report 2 cases of pulmonary valve endocarditis (PVE), highlighting the importance of echocardiography in the assessment of the infected pulmonary valve. In addition, we review the published case reports of isolated PVE from 1979 to 2013 in order to study the role of echocardiography in the diagnosis of pulmonary valve masses.
