Background
The Value of Diagnosis the benign or malignat of cardiac masses by contrast enhanced ultrasound.
Method(s)
A total of 36 patients who were treated at Luoyang central Hospital of Zhengzhou University from January 2018 to January 2020 were enrolled in the present study. Cardiac masses were discovered by echocardiography in each of the patients. Contrast enhanced ultrasound（CEUS） were used to observe the shape， border and the degree of enhance of cardiac masses, and ultrasound-guided biopsy was performed on some lesions. Results of CEUS were compared with the results of pathology or other imaging examination (CT or MRI).
Result(s)
Confirmed by pathological results or other imaging examination ，among 36 patients, 30 were benign(15 were diagnosed as thrombus, 10 as myxoma, 1 as papillary elastic fibroma, 2 as rhabdomyoma, 1 as tuberous sclerosis and 1 as left ventricular three chamber heart) and 6 were malignant(3 were diagnosed as mediastinal lymphoma invading the heart, 1 as thymic lymphoma invading the heart, and 2 as metastatic tumor).Among the 6 malignant cases， 5 cases showed irregular margin, unclear surrounding tissue boundary, and contrast enhanced ultrasound showed high enhancement; Among the 30 benign cases,26 cases showed no enhancement or low enhancement, 28 cases showed smooth boundary and clear boundary with adjacent tissue. There were significant differences between benign and malignant cases in above aspects. Contrast enhanced ultrasound can clearly show the tumor boundary and adjacent relationship, which is conducive to ultrasound-guided puncture.
Conclusion(s)
CEUS can show the boundary, adjacent relationship and blood supply of cardiac mass clearly, which is benefit to diagnosting the nature of cardiac mass.

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.
