Intramural Hematoma and Oozing Rupture of Left Atrium after Resection of Wide-Based Left Atrial Myxoma

Myxomas are rare tumours but are the most common benign tumours of the heart. They can arise from any heart chamber. However, they arise more frequently from the left atrium. They have rarely been described as originating in early age. A case of left atrial myxoma successfully removed using cardiopulmonary bypass in a 8-year-old child is presented. Review of the literature emphasizes the rarity and clinically aggressive behavior of this tumor in this age group. The object of this case report is to present myxoma in children and to evaluate possible differences between young and adult patients.

The Mean

We report the case of a 41-year-old female patient with symptoms of cerebrovascular accident manifesting with loss of consciousness during episodes of cough. Computed multislice chest tomography showed a 7.3- by 4.15-cm mass in the left atrium. A transesophageal echocardiogram showed a giant mass in the left atrium that passed through the mitral valve to the left ventricle, and severe obstructive stenosis was suggested by the mean transmitral gradient. After a comprehensive assessment of the mass, we decided to perform surgery. The pedunculated and fragile mass was attached to the interatrial septum with its handle, and the majority of it prolapsed through the mitral valve to the left ventricle and became stacked among the mitral valve leaflets. The removed mass was analyzed histopathologically and was found to be a myxoma. It is important for the cardiac surgeon to surgically remove an atrial myxoma because of the risks associated with embolization, including sudden death, as myxoma can block the blood supply from the atrium to the ventricle.

Rheumatic Mitral Stenosis

Primary cardiac tumors are very rare. Atrial myxomas are the most common primary tumors and are commonly located in the left atrium. Myxomas can cause mitral valve inflow obstruction and can present with clinical signs and symptoms of mitral stenosis and the possibility of myxoma should be considered in differential diagnosis of mitral stenosis. Left atrial myxoma is rarely associated with rheumatic mitral stenosis. Transesophageal echocardiography plays a major role in the diagnosis of this tumor. We report a case of an extremely rare association between left atrial myxoma and rheumatic mitral stenosis. Because of its location and mobility, a thrombus in the left atrium may have a similar appearance to left atrial myxoma. However, a careful inspection of features of the left atrial mass may allow a diagnosis of left atrial myxoma. In our case, the site near the atrial septum, heterogeneous echogenicity, and detection of a stalk connecting the myxoma to the atrial septum were inspected. Such findings essentially exclude thrombus.

Myxomas are the most common benign tumors of the heart and are often locatedin the left atrium and interatrial septum. They are rarely seen in the right atriumand ventricles. Myxoma usually has a benign character, but when it reaches largevolumes it causes severe mechanical obstructive symptoms in patients. Shortness ofbreath, dizziness, cough, palpitation may be its symptoms. Also constitutional complaintssuch as fever, myalgia and weight loss can be seen in patients. This case isabout a 82-year-old female patient with large size atrial mxyoma that was detectedby echocardiography.

Unusual Origin

ABSTRACT Atrial myxoma is the most frequent intracardiac tumor, accounting for nearly 50% of benign cardiac tumours in adults. We present here a rare case report of a solitary left atrial myxoma attached to the left atrial wall near the origin of the right pulmonary vein. The stalk of tumor was not attached to the interatrial septum, which is the most common site of attachment. Instead, it was attached on the wall of left atrium adjacent to the interatrial septum. Surgical exploration confirmed its attachment in the left atrium near the origin of right upper pulmonary vein. How to cite this article Bhardwaj V, Makhija N, Bhoje A, Chitara KK.

Abstract Background Myocarditis is an uncommon, potentially life-threatening disease that presents with a wide range of symptoms. In acute myocarditis, chest pain (CP) may mimic typical angina and also be associated with electrocardiographic changes, including an elevation of the ST-segment. A large percentage (20–56%) of myxomas are found incidentally. Case summary A 62-year-old female presenting with sudden onset CP and infero-lateral ST-elevation in the electrocardiogram. The diagnosis of ST-elevation myocardial infarction was presumed and administered tenecteplase. The patient was immediately transported to a percutaneous coronary intervention centre. She complained of intermittent diplopia during transport and referred constitutional symptoms for the past 2 weeks. Coronary angiography showed normal arteries. The echocardiogram revealed moderate to severe left ventricular systolic dysfunction due to large areas of akinesia sparing most of the basal segments, and a mobile mass inside the left atrium attached to the septum. The cardiac magnetic resonance (CMR) suggested the diagnosis of myocarditis with concomitant left atrial myxoma. The patient underwent resection of the myxoma. Neurological evaluation was performed due to mild vertigo while walking and diplopia in extreme eye movements. The head magnetic resonance imaging identified multiple infracentimetric lesions throughout the cerebral parenchyma compatible with an embolization process caused by fragments of the tumour. Discussion Myocarditis can have various presentations may mimic acute myocardial infarction and CMR is critical to establish the diagnosis. Myxoma with embolic complications requires emergent surgery. To the best of our knowledge, this is the first case reported in the applicable literature of a myxoma diagnosed during a myocarditis episode.
