Abstract
Objective To analysis the pathogenies which result in the simple enlargement of right heart, to provide ideas about the Echocardiograph diagnosis of this disease. Methods This study retrospectively analyzed 2086 patients diagnosed as right heart enlargement by Echocardiography in the Affiliated Union Hospital of Huazhong University of Science and Technology from January 2013 to May 2015, include the characteristics of echocardiography image and clinical data, then summarized the clinical pathogenies of right heart enlargement. Results A total of 2086 cases were collected, 1098 cases were congenital heart diseases (52.64%), including 804 cases of simple congenital heart diseases (38.54%), ASD 674 (32.31%), 294 cases of complex congenital heart diseases (14.09%). Three hundred and seventy three cases of secondary enlargement after operation of Congenital heart diseases and valvular diseases (17.88%).
