Abstract
Objective To improve the diagnosis and differential diagnosis ability for different type of anomalous origin of the left coronary artery from the pulmonary artery(ALCAPA)by summarizing patient's echocardiography features and in combination with its clinical and electrocardiogram performances. Methods The echocardiography results of twenty-four cases with confirmed diagnosis of ALCAPA by surgery were retrospectively reviewed. According to the development of coronary artery collateral circulation,patients were divided into infantile type and adult type. The different and the common echocardiography features were summarized in two types of ALCAPA. Results The same echocardiography features of infantile and adult types:①There was no left main coronary artery ostium in left coronary cusp,in stead,the left coronary artery( LCA)was originated from pulmonary artery. ②Left ventricle chamber was enlarged obviously. The segments movement of interventricular septum and anterior wall of left ventricle was disorderd. The systolic function of left ventricle was reduced. ③The fibrosis of left ventricle was extensive and the area of endocardium was significant. ④The echo of mitral chordae tendineae and papillary muscle was enhanced. ⑤The diameter of right coronary artery( RPA)was significantly dilated. ⑥The flow of left coronary descending and circumflex branch was inversed.⑦The mitral regurgitation was mild or severe. The following features differed in infantile and adult types. The significant collateral vessels were established between the RCA and LCA in adult type,however it was not the case for infantile type. The collateral vessels were less in infantile type. Conclusion The different types of ALCAPA have some specific echocardiography features. Combining patient 's echocardiography features with clinical and electrocardiogram performances,the accurate diagnosis can be achieved.关键词
