Key result
Surgical removal and histopathological evaluation of a left ventricular mass in a 35-year-old man with prior myocardial infarction revealed it to be a myxoma rather than a thrombus.
Why the study?
Left ventricle myxomas are extremely rare and can be easily mistaken for a thrombus.
Case Report (n=1)
Left ventricular myxomas are extremely rare and can mimic thrombi, especially in patients with prior myocardial infarction, highlighting the importance of surgical excision and histopathology for definitive diagnosis when masses do not respond to anticoagulation.
Myxomas can mimic post-MI thrombi; this case leaves open whether histopathology is warranted for nonresponsive LV masses.
Myxomas arising from the left ventricle (LV) are extremely rare and can be easily mistaken for a thrombus. We report a case of a 35-year-old man who presented with an acute cerebrovascular accident, having had a prior history of an anterior wall myocardial infarction 2 years back with an echocardiographic evaluation showing mild LV systolic dysfunction. His present prothrombotic workup revealed hyperhomocystinaemia and elevated levels of factor VIII. Present echocardiography revealed a mass arising from a scarred LV wall. Considering the possibility of a thrombus, he was initially started on parenteral anticoagulation. Unfortunately, consequent echocardiogram evaluation showed no reduction in size of the LV mass hence surgical removal was done. Histopathological evaluation unveiled the mass to be a myxoma.
