摘要

Cardiac myxomas,the commonest primary benign cardiac tumors,are extremely rare,with an incidence ranging from 0.0017 to 0.19%and only about one-fi fth of them originating from the right chambers of the heart.A 60-year-old woman was admitted because of recurrent attacks of chest tightness and shortness of breath.Transthoracic echocardiography detected a giant mass in the right atrium;myxoma was indicated by[18 F]fl uorodeoxyglucose PET/CT.Preoperative selective coronary angiography was performed to assess the extent and severity of coronary stenosis,and showed a strongly neovascularized right atrial mass supplied by two feeding vessels with multiple branches from the left and right coronary arteries.The myxoma was successfully excised with open heart surgery and the patient was free of myxoma recurrence during the 3-year follow-up.
