Pulmonic valve endocarditis usually occurs in IV drug addicts or patients with congenital heart disease, most commonly pulmonic stenosis, patent ductus arteriosus, tetralogy of Fallot, and ventricular septal defect.

The diagnosis of pulmonic valve endocarditis is difficult clinically and echocardiography is a reliable method to detect the presence of pulmonic valve endocarditis. Diagnostic finding is vegetations on the pulmonic valve appear as shaggy echo-dense masses or thickening of the pulmonic valve during diastole and/or systole.

The prevalence of pulmonic valve endocarditis has increased significantly recent years, especially among intravenous drug addicts.

However, few reports have dealt with the echocardiographic and clinical features of pulmonic valve endocarditis. We, therefore, reviewed the clinical spectrum and echocardiographic features of pulmonic valve endocarditis in two patients with ventricular septal defect.
