三房心的影像学诊断(附12例报告)

Imaging diagnosis of cor triatriatum(a report of 12 cases)

目的 评价经胸二维超声心动图 (2Dechocardioliography ,2DE )、心血管造影(cardioangiography ,CAG)和MRI在三房心诊断中的作用。方法 经手术证实的三房心 12例 ,其中行经胸 2DE检查 12例 ,CAG检查 6例 ,MRI检查 8例。结果 3种影像方法正确诊断三房心分别为经胸2DE 7例 (7/ 12 ) ,CAG 4例 (4 / 6 ) ,MRI 8例 (8/ 8)。MRI能较清晰地显示左房内的异常隔膜和隔膜孔的大小。

Objective To evaluate the clinical efficacy of transthoracic two dimensional echocardiography, cardioangiography (CAG), and MRI in the diagnosis of cor triatriatum. Methods Twelve cases of cor triatriatum were confirmed by operation. Imaging examination was performed in 12 cases by transthoracic two dimensional echocardiography, 6 cases by CAG, and 8 cases by MRI. Results The diagnostic accuracy of cor triatriatum was 7 out of 12 by UCG, 4 out of 6 by CAG, and 8 out of 8 by MRI, respectively. MRI provided excellent delineation of the intraatrial membrane and the size of the membrane orifice. Conclusion MRI was of great value in the diagnosis of cor triatriatum.
