Left ventricular myxoma: case report

Left atrial myxoma presenting with acute pulmonary edema and syncope in a middle-aged black African woman: a case report

Cardiac myxoma is a very rare benign cardiac neoplasm. Its annual incidence globally is between 0.5 to 1 case per one million individuals. It has a 0.03% prevalence rate in the general population. It commonly occurs in the left atrium, but can also be located in the other heart chambers. Its clinical presentations are variable, non-specific, and can mimic various cardiovascular and systemic diseases, posing a diagnostic dilemma. Thus, a high index of suspicion with appropriate use of radiologic and laboratory diagnostic tools is essential for its accurate diagnosis and management. The diagnosis and management of a rare case of left atrial myxoma in a middle-aged African woman who presented with heart failure-like symptoms, features of acute pulmonary edema, and syncope is presented in this literature. The diagnosis was suspected following echocardiography. The tumor was surgically excised, and the diagnosis was confirmed histopathologically. The patient´s post-operative condition has been excellent.

Left Ventricular Myxoma: A Case Report

Cardiac myxomas are the most common primary cardiac neoplasms, with only a small percentage being found in the left ventricle. Herein, we describe a 25-year-old male who presented with a complaint of chest pain for almost three months and was found to have a 2x2 cm encapsulated tumor attached by a 2-3 mm stalk to the mid-septum, 5 cm below the aortic annulus, via echocardiography. Additionally, a chest CT angiography was performed and revealed a small defect in the left ventricle with a low attenuation density originating from the septum. The tumor was later managed surgically with a median sternotomy approach, and left ventricular myxoma was confirmed histopathologically. Even though cardiac myxomas are incredibly uncommon, they are usually located in the left and right atria and are very unlikely to present in the left ventricle. This incident highlights the importance of taking cardiac myxoma into account as a potential differential diagnosis in cases of chest pain to prevent any further complications.

Left atrial myxoma with left ventricular myxoma diagnosed by ultrasound examination: A case report

RATIONALE

Left ventricular (LV) myxoma is a rare type of benign cardiac tumor, which may result in unfavorable consequences due to embolism, arrhythmia, obstruction to the outflow tract, and other constitutional symptoms. LV myxoma can be easily misdiagnosed as LV thrombosis. Although some literatures have reported LV myxoma, the echocardiographic features of Left atrial (LA) myxoma with LV myxoma have rarely been reported till date. Here, we report case of LA myxoma with LV myxoma diagnosed by echocardiographic examination.

PATIENT CONCERNS

A 56-year-old male patient suffering from chest tightness and asthma for 6 months and progressive aggravation for 1 month was admitted to our hospital.

DIAGNOSIS

Echocardiographic imaging gave the suspicion of LA myxoma with LV myxoma, which was confirmed by pathology.

INTERVENTIONS

This patient was treated surgically.

OUTCOMES

The patient had no postoperative complications and is currently under regular follow-up.

LESSONS

Echocardiography can be an effective imaging method for the evaluation of LV myxoma. The combination of echocardiography and clinical symptoms may help to make an accurate diagnosis.
