Discovering, diagnosing and treating CHD early is important to improve the existence rate and the existence quality of the patients. Modern cardiovascular image can not only provide the cardiovascular conformation and dissection, but also provide the information of the blood flow dynamics and the myocardial contractibility and extendibility. Echocardiography and X-ray could guide the interventional treatment.PURPOSE1.To compare the accuracy of transthoracic echocardiography (TTE) and cardiovascular digital imaging (CVDI) in measuring simple defect size and to discuss their use in interventional treatment. 2.To study comparatively the change of heart size and function before and after the...
