Abstract Objective: Through comparing ultrasonic imaging characteristics and the results of surgical pathological diagnosis and clinical follow-up of cardiac tumor, to summarize the ultrasonic imaging characterization and improve the identification of it. Method: Sixty-three cases of suspected cardiac tumor were found by color Doppler echocardiography examination in the First Affiliated Hospital of Tsinghua University from January 2003 to October 2019. The clinical features, echocardiograms characteristics, the results of surgical pathological diagnosis and clinical follow-up of these patients were compared and analyzed retrospectively. Results: Among 63 patients, 27(43%) were males, and 36(57%) were females. The age range was from 4 months to 83 years old. The average age was 35.5 years. All cardiac tumors obtain pathologic confirmation. There were 49 cases of benign tumors, including 28 patients with myxoma and 21 patients with other types. Eleven cases of malignant tumors and 2 cases of metastatic tumors, 1 case of thrombus. Benign myxoma was diagnosed in 28 cases preoperatively by ultrasound examination, which were consistent with surgical pathological results with accuracy of 100％． However there were 23 cases whose pathologic types could not be determined by ultrasound examination． Twenty cases were speculated as benign tumors and 3 cases were speculated as malignant tumor, but 21 cases were diagnosed as benign tumors, 1 case was diagnosed as malignant tumor and 1 case was diagnosed as thrombus according postoperative pathological results． Twelve cases diagnosed as malignant by UCG, being consistent with postoperative pathological results． Conclusion: The accuracy of ultrasonography in predicting myxoma is high． Cardiac tumors that invaded the heart system and were associated with pericardial effusion were more likely to be malignant. Ultrasound was the main examination in the diagnosis of cardiac tumors, combined with the history, by scanning the special features of the sonogram, misdiagnosis and missed diagnosis can be avoided or reduced.
