Left Ventricular Myxoma Leading to Stroke

Abstract

Primary cardiac tumors are rare, and most are myxomas. Only approximately 5% of cardiac myxomas originate from the ventricles.We report the case of a 23-year-old man presenting with right hemiplegia and muscle strength degeneration under a diagnosis of stroke. Transthoracic echocardiography revealed a 29 × 26 mm mass arising from the anterior interventricular septum. The tumor was surgically removed, and histology confirmed the diagnosis of left ventricular myxoma.We report its clinical features and treatment to add to the current knowledge.

Left atrial myxoma with left ventricular myxoma diagnosed by ultrasound examination

“…Compared with LV thrombosis, the typical LV myxoma has higher mobility and narrower base. Kong Y et al [ 4 ] reported a TTE finding of LV myxoma leading to stroke. Through TTE, Qin W et al [ 12 ] observed a LV myxoma attached at the base of the anterolateral papillary muscle in a patient with no history of syncope, palpitation, or dyspnea.…”

“…However, Left ventricular (LV) myxoma could be located in any part of the left ventricle. [ 4 ] LV myxoma is usually benign, but may lead to fatal consequences including emboli and cardiac arrhythmias resulting in sudden death. [ 5 , 6 ] Because of the deadly outcome of this disease, it is important to make a correct diagnosis.…”

“…Left atrial (LA) myxoma usually originates in atrial septum. However, Left ventricular (LV) myxoma could be located in any part of the left ventricle [4] . LV myxoma is usually benign, but may lead to fatal consequences including emboli and cardiac arrhythmias resulting in sudden death [5,6] .…”
