The purpose of this study was to evaluate the prevalence and clinical significance of incidental cardiac findings in non-ECG-gated chest CT.
Non-ECG-gated chest CT examinations of 300 patients were retrospectively analyzed for incidental cardiac findings. Subsequently, these findings were evaluated for their clinical relevance by a cardiologist.
A total of 107 out of 300 examined patients had 174 incidental cardiac findings including coronary calcification (90), aortic/mitral valve calcification (42), iatrogenic changes (23), pericardial effusion (6), dilatation of the heart (4), myocardial changes (3), thrombus in the left ventricle (2), constrictive pericarditis (2) and atrial myxoma (1). Of the cardiac findings 51% were described in the written report and in 53 out of the 107 patients the cardiac findings were unknown. Newly detected incidental findings from 8 patients were rated as clinically significant: pericardial effusion (4), constrictive pericarditis (1), thrombus in the left ventricle (1), atrial myxoma (1) and dilatation of the heart (1).
Incidental cardiac findings are frequent in non-ECG-gated chest CT and may have a high clinical relevance.
本研究的目的是评估非心电图门控胸部CT中偶然发现的心脏病变的患病率及其临床意义。
对300例患者的非心电图门控胸部CT检查进行回顾性分析，以寻找偶然发现的心脏病变。随后，心脏病专家对这些病变的临床相关性进行评估。
300例受检患者中，共有107例出现了174处偶然发现的心脏病变，包括冠状动脉钙化（90处）、主动脉/二尖瓣钙化（42处）、医源性改变（23处）、心包积液（6处）、心脏扩大（4处）、心肌改变（3处）、左心室血栓（2处）、缩窄性心包炎（2处）和心房黏液瘤（1处）。在这些心脏病变中，51%在书面报告中有描述，107例患者中有53例的心脏病变未被发现。8例患者新发现的偶然病变被评为具有临床意义：心包积液（4例）、缩窄性心包炎（1例）、左心室血栓（1例）、心房黏液瘤（1例）和心脏扩大（1例）。
在非心电图门控胸部CT中，偶然发现的心脏病变很常见，且可能具有较高的临床相关性。
