Does transesophageal echocardiography improve the detection of right atrial appendage angiosarcoma compared to conventional transthoracic echocardiography?
Transesophageal echocardiography is a valuable imaging modality for detecting right atrial appendage angiosarcomas that may be missed by conventional transthoracic echocardiography.
Primary cardiac tumors are extremely rare, among which malignancies comprise about 15-25%. As the most common type of primary cardiac malignancies, angiosarcomas tend to arise in the right heart, especially right atrium. In this case report, we presented a 32-year-old female with primary cardiac angiosarcoma in the right atrial appendage detected by transesophageal echocardiography, as it is difficult to display on conventional transthoracic echocardiography.
