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.

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

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.

Context: Cardiac tumors are rare and myxomas are the most prevalent between them. Although histologically benign, they may cause severe effects given their intracardiac location. Unspecific symptoms compromise the diagnosis, leading to complications such as changes in the cerebral vascular dynamics. Case report following the CARE guidelines. Case report: A 62-year-old woman was admitted to a high complexity hospital in Minas Gerais, with history of unstable angina, aphasia, right hemiparesis, dysarthria, claiming precordialgia with strong intensity. Complained hyporexia and weight loss during the last month. Medical history of 7 transient ischemic attacks (TIA) in the last two years. Physical examination with no abnormalities. Chest x-ray and transesophageal echocardiogram showed bilateral neovascularization and 4.9 x 2.9 cm dimension mass in the left atrium. Coronary angiography revealed proximal calcification and atherosclerotic plaque occluding 40% of the flux in the middle third of the anterior descending artery, pointing to the coexistence of coronary disease and left atrial myxoma. The occurrence of a TIA was determined and the prescription of an anticoagulant to avoid future embolic events. A surgical approach was necessary. Biopsy concluded myxoid and hyaline-rich stroma tumor, evident vascular system, star-shaped cells isolated or forming small groups, confirming myxoma diagnosis. After a ten-day hospitalization, the patient was clinically stable, and was discharged after health education. Conclusion: Cardiac tumors such as myxomas lead to important cerebral vascular consequences, so that the clinical investigation is essential to the differential diagnosis between a stroke and the TIA, to provide adequate treatment and disease prevention.

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.

Myxomas are benign and the most common tumors of the cardiac muscle (Reynen, 1995). They are predominantly located in the left atrium. Clinical manifestations may vary according to the localization and the size of the myxoma. On the other hand, imaging of a myxoma by contrast dye during coronary angiography is a rare sign, which displays the vascular supply of the tumor. Here, we report the case of a 51-year-old man presenting with presyncope and palpitations due to a giant left atrial myxoma having its vascular supply from the right coronary artery (RCA).

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.

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.
