OBJECTIVE
Primary heart tumors are rare and most of them are benign. The majority of benign cardiac tumors are myxomas, although almost all malignant cardiac tumors are sarcomas. Malignant cardiac tumors usually appear in children.
METHODS
There have been cases described of stroke secondary to embolism caused by cardiac sarcomas, but it is rarely the first manifestation of the tumor.
RESULTS
We describe a 48-year-old man who suffered a cardioembolic stroke secondary to cardiac sarcoma.
CONCLUSION
Malignant cardiac tumors typically appear through 1 of 4 mechanisms: obstruction to blood flow and interference with valve function; local invasion causing arrhythmias or pericardial effusion; embolic phenomena or systemic symptoms. We analyze the characteristics of cardiac sarcoma and the pathophysiology of embolism.
目的
原发性心脏肿瘤罕见，且大多数为良性。大多数良性心脏肿瘤是黏液瘤，尽管几乎所有恶性心脏肿瘤都是肉瘤。恶性心脏肿瘤通常出现在儿童中。
方法
有病例描述了心脏肉瘤引起栓塞继发的中风，但这很少是肿瘤的首发表现。
结果
我们描述了一名48岁男性，他因心脏肉瘤继发心源性栓塞性中风。
结论
恶性心脏肿瘤通常通过以下4种机制之一出现：血流阻塞和瓣膜功能干扰；局部侵犯导致心律失常或心包积液；栓塞现象或全身症状。我们分析了心脏肉瘤的特征和栓塞的病理生理学。
