Isolated pulmonic valve endocarditis is a rare condition. The clinical and laboratory finding are not specific and experiences about that are limited. Most cases of that occur in children with congenital heart disease or in intravenous drug abusers and the main predisposing factor in adults is intravenous drug abuse. The most common pathogens are staphylococcus aurous and coagulase negative staphylococcus.
In this case report we present a 27 years old man with chronic fever (4 months) and a history of congenital ventral septal defect (VSD). Echocardiography revealed the pulmonic valve and pulmonary artery vegetations. He referred for surgery after 3 weeks of intravenous antibiotic therapy.
Careful evaluation of pulmonic valve in echocardiography should be done, when ever vegetation is not detected in other valves, and clinical suspicion for infective endocarditis is high.
孤立性肺动脉瓣心内膜炎是一种罕见疾病。其临床和实验室检查结果不具有特异性，相关经验有限。大多数病例发生于患有先天性心脏病的儿童或静脉药物滥用者，而成人中的主要易感因素是静脉药物滥用。最常见的病原体是金黄色葡萄球菌和凝固酶阴性葡萄球菌。
在本病例报告中，我们呈现了一名27岁男性，有慢性发热（4个月）及先天性室间隔缺损（VSD）病史。超声心动图显示肺动脉瓣和肺动脉有赘生物。在进行了3周的静脉抗生素治疗后，他接受了手术治疗。
当在其他瓣膜未检测到赘生物而临床高度怀疑感染性心内膜炎时，应在超声心动图中对肺动脉瓣进行仔细评估。
