Introduction: Cardiac myxomas are the most common primary tumors of the heart with high embolic potential. Case Presentation: We present a young man with progressing stroke and atrial myxoma in an unusual site from the left upper pulmonary vein. Conclusions: Intravenous (IV) thrombolysis can be safe in patients with intracardiac myxoma and CNS embolization after good case selection. However, further studies are needed for better decision-making.

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.

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.

Cardiac myxomas may have different clinical presentations that may expose the patient to sudden death due to obstruction of the left ventricle inflow. 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.

Background: Recurrence of sporadic cardiac myxoma remains unusual but the seriousness of the situation justifies the realization of a surgical resection as complete as possible with post-operative clinical and echocargdiographic monitoring. Case presentation: We recall the case of myxoma of the left atriumin a 64-year-old women complicated by functional mitral stenosis and heart failure. She underwent urgent heart surgery, during which a friable tumor attached by a sessile base to the anterior atrial septum was removed. The postoperative effects were complicated by a pulmonary embolism. Eight months later, the patient consulted for exertional dyspnea with an echocardiographic image in favor of a recurrence of myxoma of the left atrium. Conclusion: Several mechanisms have been proposed to explain such recurrence, the most avoidable remain incomplete surgical resection and Implantation of embolic fragments of the original tumor in the myocardium due to a previous surgery.

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.

Variable Clinical Presentation

AbstractPrimary tumors of the heart are rare. The majority of them are benign, the left atrial myxoma being the most frequent one. Clinical appearance varies from unapparent to life-threatening complications such as stroke, acute heart failure, or even sudden death. Diagnosis and consecutive surgical treatment strongly depend on the clinical symptoms, but their extent does not correlate with the risk for serious complications. Therefore, patients with variable clinical presentation can be especially endangered. Consequent diagnostic and immediate operative therapy is essential.

A second recurrence of an excised nonfamilial cardiac myxoma is rare. Myxomatous cerebral aneurysms as a complication of cardiac myxomas are equally rare. A unique case of a patient with a total of 4 myxomas over a 20-year interval is presented. Her most recent presentation was a second recurrence of a left atrial myxoma, a de novo right atrial myxoma, and multiple cerebral myxomatous aneurysms. The challenging reconstruction of the normal anatomy was achieved with the use of porcine extracellular matrix patches. A diagnostic cerebral angiogram was later performed, and the aneurysms will be monitored for growth and possible intervention.

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.
