Key result
Rivaroxaban therapy successfully dissolved a giant left atrial ball thrombus over seven months, demonstrating the value of cardiac magnetic resonance in diagnosing and monitoring cardiac masses.
Why the study?
A male patient with a giant left atrial cardiac mass in an atypical location needed quick histological discrimination for individualized and effective treatment.
Case Report (n=1)
CMR is a valuable tool for the precise diagnosis of cardiac masses, and rivaroxaban can be an effective alternative to surgery for treating a giant left atrial thrombus.
Suggests rivaroxaban as potential alternative to surgery for left atrial thrombus; leaves open need for confirmatory studies.
Male patient with left atrial cardiac mass was in need of a quick diagnosis for individualized and effective treatment. Transthoracic echocardiography showed presence of а giant left atrial cardiac mass with atypical location for thrombus. Cardiac Magnetic Resonance (CMR) Imaging was performed for histological discrimination, and showed a large cardiac mass wall attached in the left atrium, homogeneous, with diameter of 3.4cm x 3.2cm. Late Gadolinium Enhancement sequences revealed black avascular tissue without signal, confirming the characterization of a thrombus. The patient refused hospital initiation of low molecular weight heparin treatment and started treatment with Rivaroxaban. Six weeks later he presented with NYHA class II, almost complete dissolving of the thrombus on CMR scan. Seven months from the initial CMR scan, echocardiography screen was done showing complete absence of the left atrial mass. With this case report we have demonstrated the significance of the CMR as one step further in the precise diagnostics of cardiac masses, solving critical clinical dilemma.

Trajcheski et al. (2023) conducted a case report in Left atrial ball thrombus (n=1). Rivaroxaban was evaluated on Thrombus resolution. Rivaroxaban therapy successfully dissolved a giant left atrial ball thrombus over seven months, demonstrating the value of cardiac magnetic resonance in diagnosing and monitoring cardiac masses.
