Clinical introduction

A 66-year-old woman was admitted to our hospital for a 2-year history of shortness of breath on exertion and intermittent fatigue, without chest pain and palpitations. Her medical history was unremarkable. Physical examination found normal vital signs, but a grade 2/6 systolic murmur best heard at the lower left sternal border; she had no lower extremity oedema. ECG and blood test showed no obvious abnormality. Transthoracic echocardiography showed an intracardiac mass concomitant with moderate tricuspid regurgitation (figure 1A), since the abnormal findings, a contrast-enhanced chest CT (figure 1B) was performed for further evaluation.
