心脏原发性肿瘤临床罕见,而一半以上是粘液瘤。心脏粘液瘤可发生于任何心腔的心内膜面,95%发生于心房,75%以上发生于左心房,最好发的部位是左房卵园窝区。Ribbert 认为肿瘤发生自残留的胚胎性粘液样组织,此种残留组织多见于卵园孔的边缘部,故可解释为何肿瘤多发生于该处。好发年龄自幼年至老年均有报告,而最多见于中年。较多发生于女性,女与男之比为3∶1。近年每有心脏粘液瘤家族史的报道,1976年 Tanen等报告一家母子四人均发现有心房粘液瘤;另外,这位妇女的父兄均为突然死亡而未确诊,从这个家庭的资料来看,此病为一连续显性遗传。 Primary cardiac tumors are rare clinically, and more than half are myxomas. Heart myxoma can occur on the endocardial surface of any heart chamber, 95% occurs in the atrium, more than 75% occurs in the left atrium, and the best site is the left atrial ovary. Ribbert believes that tumors develop from residual embryonic myxoid tissue. This type of residual tissue is more common in the margins of the ovary or foramen, and it can explain why tumors occur in this area. The prevalent age has been reported from childhood to old age, and is most commonly seen in middle age. More often occurred in women, the ratio of women to men was 3:1. In recent years, the family history of cardiac myxoma has been reported. In 1976, Tanen et al. reported that a mother and a mother were found to have atrial myxoma; in addition, the woman’s father and brother all died suddenly and had not been diagnosed. From the family’s data, this The disease is a continuous dominant inheritance.
