Cardiac Myxomas

Cardiac myxomas are benign tumors composed of sparse stellate cells in an extensive mucoid stroma. The surface of these tumors is often friable and gelatinous. Their intracardiac location makes embolization a constant threat. We report a patient who had diffuse systemic embolization of a left atrial myxoma coincident with a low-velocity frontal motor vehicle crash.

Rheumatic Heart

Primary cardiac neoplasms are uncommon with an overall incidence of 0.0017 to 0.02%. The majority of these tumors are benign and half of these tumors are myxomas. About 75% of them are located in the left atrium. Acute embolic cerebral stroke is major problem with increased mortality and morbidity. Embolus arising from cardiac origin costitutes about 20% of ischemic strokes. Atrial fibrillation is cause of more than 50% of cardiogenic emboli. Congenital heart diseases, such as atrial septal defect, patent foramen ovale, prosthetic and rheumatic heart valvular disease, dilated cardiomyopathy and endocarditis are predisposing factors for cardiogenic emboli. Emboli from primary tumors of the heart are extremely rare, with an incidence of 0.02 %. Myxoma is a potential source of systemic embolization to the brain or peripheral arteries. Thus, cerebral stroke may be the first manifestation of the presence of left atrial myxoma.

The authors report a case of 34 years old male who was diagnosed with left atrial myxoma that presented as mitral valve obstruction with severe pulmonary hypertension. He underwent emergent sternotomy under cardiopulmonary bypass and the myxoma was successfully removed. The postoperative course was uneventful.

Myxoma is the most common primary tumor of the heart. The rarity of infected cardiac myxomas leads to numerous diagnostic and therapeutic difficulties. We present a case of infected left atrial myxoma caused by methicillin-sensibleStaphylococcus aureusin a 48-year-old woman complicated by systemic embolism and septic shock.

Myxoma is benign tumor of the heart. It is mostly located in the left atrium and revascularized by the left and right coronary artery in 30% to 40% of cases. Symptoms of these neovascularized cardiac myxomas are typically quite variable, from obstruction of mitral valve to coronary embolism resulting in acute myocardial infarction. In this case, left atrial myxoma that is revascularized by nodal branches of the right coronary artery presented as a sick sinus syndrome, which is rare in literature.

Cardiac myxomas are rare tumors. Esophageal adenocarcinomas are common tumors of the gastrointestinal tract. Simultaneous occurrence of these tumors has not been reported. A 52-year-old gentleman presented to our hospital with dysphagia and was diagnosed with esophageal adenocarcinoma. Routine echocardiography discovered a cardiac tumor in the left atrium. The cardiac tumor was surgically removed and biopsy confirmed a myxoma. We removed the cardiac tumor as the first step and then initiated neoadjuvant chemotherapy. It is ideal to constitute a multidisciplinary team to decide on the course of treatment in such cases.

Cardiac Myxomas

Cardiac myxomas are benign primary tumors of the heart that require prompt surgical intervention because of the possibility of developing syncope and hemodynamic or embolic complications. From 1 January 1981 to 31 December 1996, 20 patients (11 male and 9 female) underwent surgery for cardiac myxoma at Singapore General Hospital. Nineteen patients had a left atrial myxoma and 1 had a right atrial myxoma. Five patients had concomitant coronary artery disease including one with severe mitral regurgitation. Nine patients presented with progressive dyspnea, 5 with systemic embolus, 2 with syncope, 3 with congestive cardiac failure, and 1 with right ventricular failure. In 6 patients the diagnosis was established by cardiac catheterization and 14 patients were diagnosed by two-dimensional echocardiography. Cardiopulmonary bypass with mild to moderate systemic hypothermia was used for excision of the myxoma in all cases. Five patients had concomitant coronary artery bypass grafting and 2 had concomitant mitral valve replacement. There was no hospital mortality among patients who had only excision of the myxoma, including a patient who had a recurrence of her left atrial myxoma 5 years after the initial excision. There were 2 deaths in patients with coexisting cardiac and other diseases. Surgical excision is recommended for all cases of cardiac myxoma. There is little risk associated with this procedure. All patients should be followed up regularly with echocardiographic assessment as there is a small risk of recurrence.

We report the fatal course of a left atrial myxoma: its systemic embolization to the coronary, cerebral, renal, and peripheral vascular beds in a 39-year-old woman resulted in rapid clinical deterioration, multiorgan failure, and death. Among reported cases of left atrial myxoma, this degree of embolic burden is exceedingly rare. In addition to reporting the patient's case, we discuss the presentation and diagnosis of possible intracardiac sources of systemic emboli.

Systemic Embolization

Myxomas are the most common primary tumors of the heart. We report an extraordinary severe case of left atrial myxoma, presenting with stroke, myocardial infarction, and multiple arterial embolism including aorta, splenic and renal arteries, and several peripheral arteries. The patient had previously been diagnosed with systemic vasculitis, a typical but less common finding caused by multiple emboli mimicking vasculitis. The myxoma was removed and atrial septum reconstruction was performed. In summary, early diagnostic differentiation of myxoma from vasculitis is critical, and immediate surgical removal of myxoma is required as the probability of thromboembolic complications increases over time.

Abstract Background Cardiac myxomas are considered the most common benign heart tumours. The clinical manifestations mainly depend on the size of the tumour. They usually vary from asymptomatic, mild non-specific symptoms, to severe obstructive cardiac and systemic findings. We describe herein a significantly large left atrial myxoma in a patient misdiagnosed with respiratory asthma. Case summary A 54-year-old lady, was diagnosed previously with asthma, presented with a history of dyspnoea on exertion, palpitations, and mild peripheral oedema. Chest X-ray suggested pulmonary congestion. Due to high suspicion of cardiac issues, transthoracic echocardiography was done revealing giant left atrial mass. Consequently, the mass was approached and excised surgically through the inverted T biatrial incision. Grossly, the mass measured 10 × 8 × 6 cm, and it had a smooth surface and was filled with gelatinous material. The histopathology confirmed benign myxoma without malignant features. Discussion Our article mainly focuses on the diagnostic challenges of a patient with atrial myxoma. The major discrepancy between the tumour size and the severity of the patient’s symptoms should draw physicians’ attention to consider atrial myxoma over a long list of differentials, in order to take immediate action to reduce the mortality and improve the overall prognosis.

Abstract Background Cardiac myxomas are the most common benign primary cardiac tumours. The natural history of left cardiac myxomas is thought to be of slowly growing tumours. Cardiac myxomas are a heterogeneous group with a variable growth rate. They present usually with stroke, valve obstruction, or non-specific symptoms. Surgical resection is the effective treatment. Case summary This case report describes a 56-year-old hypertensive and dyslipidaemic female, when she was admitted in January 1990, complaining of loss of appetite, aches, pains, and palpitations. Her workup included a transthoracic echocardiography and transoesophageal echocardiography, which showed a left atrial mass attached to the inter-atrial septum, highly suggestive of left atrial myxoma. She was referred for surgical removal of the left atrial mass. However, she was reluctant to undergo surgery as she felt better. The patient was followed-up for almost 30 years with the left atrial mass confirmed as left atrial myxoma by cardiac magnetic resonance imaging. The left atrial mass became smaller in size and more calcified. Discussion Cardiac myxomas are a group of heterogeneous tumours, thought to be slowly growing. The growth rate of cardiac myxomas prior to diagnosis is not well known, as the vast majority is treated with surgical resection immediately after diagnosis. Our case showed the natural progression of an unoperated smooth-surfaced left atrial myxoma followed-up for almost 30 years, which slowly became smaller and more calcified.
