Echo-Doppler Features of Pulmonary Valve Endocarditis

Three patients with fever and pneumonitis were found to have pulmonary valve vegetations by echocardiography. Pulsed and color flow Doppler studies demonstrated mild to moderate pulmonary valve insufficiency in these patients. All patients responded to the appropriate antibiotics without requiring valve surgery. Echocardiography is of value in diagnosing pulmonary valve endocarditis and should be considered in every patient with recurrent pneumonitis
