Generally, infective endocarditis is found at the left side of the heart. The right side infective endocaritis accounts for only 5~10% of all cases of infective endocarditis. The right side infective endocarditis occurs especially among drug users employing intravenous injection. A typical site of infection is the tricupid valve, and isolated pulmonary valve involvement is rare. It is assumed that its rarity is due to the low pressure gradients within the right heart, the low prevalence of valve disease, and the lower oxygen content of the venous blood. We describe a case of isolated pulmonary valve endocarditis requiring valve replacement. Antibiotic therapy was conducted for 4 weeks before surgery and 2 weeks after surgery. Clinical course was favorable and the patent was discharged home 18 days after surgery.
一般来说，感染性心内膜炎多见于心脏左侧。右侧感染性心内膜炎仅占所有感染性心内膜炎病例的5%至10%。右侧感染性心内膜炎尤其多见于静脉注射吸毒者。典型的感染部位是三尖瓣，单纯肺动脉瓣受累罕见。据推测，其罕见性是由于右心内压力梯度低、瓣膜疾病患病率低以及静脉血含氧量低。我们描述了一例需要进行瓣膜置换的单纯肺动脉瓣心内膜炎病例。术前进行了4周的抗生素治疗，术后进行了2周的抗生素治疗。临床过程顺利，患者术后18天出院回家。
