“…Distinction between a thrombus and a myxoma in the left atrium is not always straightforward . Left atrial myxomas characteristically appear as round or oval structures containing a mucopolysaccharide myxoid matrix, but they sometimes have a nonhomogeneous appearance, reflecting cystic areas or hemorrhages .…”

A 15 3 13 mm mobile ovoid mass attached via a 15 3 5 mm stalk to the interatrial septum in the left atrium was detected on transesophageal echocardiography and was diagnosed as a myxoma in a 70-year-old woman with chronic atrial fibrillation. She was prescribed anticoagulant therapy with warfarin before elective cardiac surgery and demonstrated no thromboembolic event during a 2.5-month period. Preoperative transesophageal echocardiography showed the disappearance of the intracardiac mass and the presence of a left atrial septal pouch, suggesting that the initial image was a thrombus originating from the left atrial septal pouch.

“…While a mass in the LAA is usually a thrombus especially in the setting of atrial fibrillation, myxomas have also been rarely reported 1,2 . The distinction between a thrombus and a myxoma in the LA is not always straightforward and cases of difficulty have been reported 1–3 . Precise diagnosis is important as treatment modalities differ and are not without risk.…”

Left Atrial Thrombus Masquerading as a Myxoma in a Patient with Mitral Stenosis

The preoperative differentiation of a thrombus from a myxoma is important but not always easy. Clinical and echocardiographic characteristics of myxoma and thrombi are not diverse enough to always reliably distinguish the two. We report the case of a patient who was found to have a left atrial appendage thrombus that was misdiagnosed as a myxoma on the basis of its imaging characteristics on cardiac magnetic resonance in addition to the detection of dense neovascularization on coronary angiography. This case highlights the unusual features of an organized thrombus that can mimic many of the distinguishing characteristics of a myxoma.

“…Tranexamic acid is effective in the treatment of trauma induced coagulopathy and blood loss. [1] We report global left and right ventricular dysfunction after tranexamic acid injection in a patient of polytrauma. A 45-year-old polytrauma patient presented with profuse bleeding from external wounds.…”

“…The few remaining tumors originate from atypical sites such as left or right ventricle and valves. [1][2][3] Although, transesophageal echocardiography is more sensitive, two-dimensional (2D) transthoracic echocardiography (TTE) is usually adequate for diagnosis. Surgical resection of the myxoma is the treatment of choice, with low morbidity and mortality.…”
