Abstract
A 39-year-old male was admitted for recurrent ischemic strokes. TEE was performed to detect the potential intra-cardiac thrombi and right-to-left shunts. A large hypermobile, echodense, irregular mass was found in the right atrium, which looked like a cluster of grapes. The motion of the components of the mass was synchronized, prolapsing into right ventricle in an octopus-like fashion during diastole. There was no evidence for PFO or other intra-cardiac shunts by color flow Doppler. The patient was referred to surgery and a continuous 30 cm long thrombus spanning from the inferior vena cava to the right ventricle was discovered.
Highlights
The right atiral masses are most likely to be either tumor or thrombi [1]
We report a Type A right atrial thrombus confirmed by pathology examination
The patient had a Type A right atrial thrombus, with which the pulmonary thromboembolism rate ranging between 79% and 98% [5]
Summary
The right atiral masses are most likely to be either tumor or thrombi [1]. The differentiation between the right atrial tumor and thrombi is difficult and often impossible without invasive interventions, despite the wide availability of echocardiography, CT scan and magnetic resonance imaging [3] [4]. In this case, we report a Type A right atrial thrombus confirmed by pathology examination. We report a Type A right atrial thrombus confirmed by pathology examination The morphology of this thrombus is unusual with a synchronized octopus-like prolapsing into the right ventricle during diastole
