Transcatheter extraction safely removes right atrial thrombus in sickle cell disease.
Case Report (n=1)
This case highlights the importance of integrating clinical context with cardiac magnetic resonance characteristics for diagnosing intracardiac masses, and demonstrates the successful use of a novel transcatheter extraction technique in a high-risk adolescent.
May support transcatheter extraction for right atrial thrombi in select sickle cell adolescents; leaves open need for prospective validation before wider use.
A 17-year-old female patient with hemoglobin SS sickle cell disease, Moyamoya disease, a history of stroke, and pulmonary embolism was incidentally found to have a large pedunculated right atrial mass on cardiac magnetic resonance imaging. The differential diagnosis included thrombus, tumor, and vegetation. She underwent cardiac catheterization for therapeutic removal and pathologic confirmation of the diagnosis. This case highlights the diagnostic challenges of right atrial masses and the importance of integrating clinical context with multimodality imaging.

Almasri et al. (2026) conducted a case report in Right atrial mass (n=1). Transcatheter extraction was evaluated on Successful removal and diagnosis of the mass. Transcatheter extraction successfully removed a right atrial mass in a 17-year-old female with sickle cell disease, which was pathologically confirmed as an organizing thrombus.
