Abstract

OBJECTIVES

A calcified thrombus is rare, but needs to be recognized and to be differentiated from calcified nodule.

METHODS

We report a case of acute coronary syndrome and a large intracoronary mobile mass, which was identified as a calcified thrombus by optical frequency domain imaging and intravascular ultrasound.

RESULTS

Successful direct stenting indicated that mobile mass was a calcified thrombus, not a calcified nodule.

CONCLUSIONS

Cardiologists should be aware that an intracoronary mobile mass could be a calcified thrombus. This diagnosis can be confirmed through the combined use of optical frequency domain imaging and intravascular ultrasound.

摘要

目的

钙化血栓较为罕见，但需要识别并与钙化结节相鉴别。

方法

我们报告一例急性冠状动脉综合征及冠状动脉内一个大型可移动团块的病例，该团块经光学频域成像和血管内超声检查确定为钙化血栓。

结果

成功进行直接支架置入术表明该可移动团块是钙化血栓，而非钙化结节。

结论

心脏病专家应意识到冠状动脉内的可移动团块可能是钙化血栓。通过联合使用光学频域成像和血管内超声可确诊。
