Description
A 10-year-old boy was referred to the department of surgery because of congenital heart disease and infective endocarditis. He was diagnosed with Williams-Beuren syndrome when he was 3-year-old.Remarkable physical examination findings included cardiac murmurs and positive Babinski sign is on the right side. He had normal body temperature at that time .A transthoracic echocardiogram revealed supravalvular aortic stenosis, pulmonary stenosis, ascending aorta almost fully filled with echogenic neoplasms, double aortic arch, pantet and embolization of the right anterior tibial artery. A contrast-enhanced full-body computed tomography further showed the three-dimensional structure of supravalvular aortic stenosis, pulmonary stenosis and double aortic arch. After conforming the diagnosis, infected lesions were removed surgically. Aortaplasty and pulmonary angioplasty were also performed to correct the cardiac anomalies. Postoperative recovery was satisfactory. The patient remains asymptomatic 3 months of after the surgery.
Key Finding(s)
The patient had a variety of rare and complex congenital heart malformations, and especially ascending aorta almost fully filled with echogenic neoplasms were rarely reperted.
Differential Diagnosis
supravalvular aortic stenosis, infective endocarditis
Implication(s)
In this case ，Williams-Beuren syndrome ,double aortic arch and ascending aorta almost fully filled with echogenic neoplasms were rare . Maybe It is a good case.

An unusual case of complex Congenital Heart Disease

ECHO ASIA is organized by Asian-Pacific Association of Echocardiography (AAE). The meeting combines the basic echocardiography training curriculum and the state-of-the-art lectures/scientific sessions provided by international as well as Asian-Pacific experts. The meeting is a unique forum where scientists from many countries in the Asian-Pacific region who are involved in the field of Doppler echocardiography gather together to exchange knowledge and skills. Various internationally distinguished faculties consent to present their findings and reveal their clinical experiences in ECHO ASIA.
