Multimodality imaging of a cardiac angiosarcoma presenting with atrial flutter.

Area of Science:

• Cardiology
• Oncology
• Medical Imaging

Background:

• Atrial flutter can present with various symptoms, necessitating comprehensive diagnostic workups.
• Cardiac tumors, though rare, require accurate and timely diagnosis for effective management.

Observation:

• A 39-year-old female presented with palpitations and dyspnea, and an electrocardiogram showed atrial flutter.
• Initial investigations involved a series of advanced imaging techniques.

Findings:

• Multimodality imaging, encompassing transthoracic echocardiography, computed tomography, and cardiac magnetic resonance imaging, was employed.
• Intracardiac echocardiography-guided tissue biopsy confirmed the diagnosis of right atrial angiosarcoma.

Implications:

• This case highlights the importance of considering rare cardiac tumors in the differential diagnosis of atrial flutter.
• Advanced imaging modalities play a critical role in the precise localization and characterization of cardiac masses.
• Early diagnosis of right atrial angiosarcoma is essential for guiding treatment strategies and improving patient outcomes.
