Papillary ‘tumours’ are small pedunculated lesions of the valve cusps and result from wear-and-tear. They are therefore frequent post-mortem findings in older patients. The vast majority are clinically silent, though occasionally such lesions when on the aortic valve may produce symptoms of myocardial or cerebral ischaemia. None has been known to cause symptoms when in the right side of the heart. A 52-year-old woman is reported who had transient episodes of right ventricular outflow obstruction related to the presence of a papillary tumour on the pulmonary valve. Extensive radiotherapy to the chest wall was thought to be a causal factor.
乳头状“肿瘤”是瓣膜尖的小带蒂病变,由磨损引起。因此,它们是老年患者尸检中常见的发现。绝大多数在临床上无症状,尽管偶尔位于主动脉瓣上的此类病变可能会产生心肌或脑缺血症状。据知,位于心脏右侧时均不会引起症状。据报道,一名52岁女性因肺动脉瓣上存在乳头状肿瘤而出现右心室流出道梗阻的短暂发作。胸壁的广泛放疗被认为是一个致病因素。
