조영심초음파도를 이용한 선천성 심장질환의 진단

Abstract

Contrast echocardiography has played an important role in the development of ultrasound as the leading noninvasive technique for the evaluation of various cardiovascular entities. This is useful in identifying normal and abnormal cardiac structures, extra and intracardiac shunts and in the evaluation of complex congenital heart problems. We studied contrast echocardiography for the patients with congenital heart diseases (33 cases), and compared the results with those of cardiac catheterization and cardiac angiography. The results were as follows 1. Sixteen of 17 cyanotic heart diseases were tetralogy of Fallot, and we could observe the interventricular right·to-left shunt and simultaneous filling of left ventricle and aorta in all patients. 2. In 11 patients with Eisenmenger syndrome, 5 patients were VSD, 4 patients ASD, and 2 patients PDA. Contrast echocardiogram showed the exact site of right to left shunt in all patients. 3. Four cases of ASD and 1 case of VSD showed negative contrast echoes, revealing left-ta-right shunts at interatrial and interventricular septum. 4. In all cases, same results were obtained by cardiac catheterization and angiography.
