在感染性心内膜炎的尸解中,肺动脉辩感染性心内膜炎仅占1.1％,单纯肺动脉瓣感染性心内膜炎很少见。当患者具有先天性心脏病或后天性肺动脉瓣疾患,并出现新的肺动脉返流性杂音、发热、肺栓塞现象和血培养阳性时,应当考虑单纯肺动脉瓣感染性心内膜炎的诊断。最后证实要靠手术或尸解。最近,由于静脉内滥用麻醉药物患者增加,肺动脉瓣感染性心内膜炎的发病也有所增加。但是在诊断上仍有一定困难,最主要的问题是不能理想的显示肺动脉瓣及其赘生物。作者复习了28例单纯肺动脉瓣感染性心内膜炎患者的临床、手术和尸解资料,对其超声心动图和微生物学方面的主要特征予以介绍,以进一步阐述这一易被忘记的综合征。
In the autopsy of infective endocarditis, the pulmonary artery debatable infective endocarditis accounted for only 1.1%, simple pulmonary valve infective endocarditis is rare. Diagnosis of simple pulmonary valve infective endocarditis should be considered when patients have congenital heart disease or acquired pulmonary valve disease and new pulmonary regurgitation murmurs, fever, pulmonary embolism, and blood culture positive. Finally confirmed by surgery or autopsy. Recently, the incidence of pulmonary valve infective endocarditis has also increased due to an increase in intravenous abuse of narcotic drugs. However, there are still some difficulties in diagnosis. The most important problem is that the pulmonary valve and its neoplasm can not be displayed satisfactorily. The authors reviewed the clinical, surgical, and autopsy data from 28 patients with simple pulmonary valve disease who received endocarditis and presented their echocardiographic and microbiological characteristics to further elucidate the easily forgotten syndrome .
