Atrial myxomas are rare primary cardiac tumors that present with obstructive, embolic, or constitutional symptoms and are effectively treated with early surgical resection.
Left atrial myxomas predominate with obstructive symptoms; leaves open optimal management timing in asymptomatic cases.
Primary cardiac tumors are extremely rare and constitute only about 5% of all cardiac tumors. Cardiac myxomas are noncancerous primary tumors of the heart and constitute about of 50% of all primary heart tumors. Left-sided atrial myxomas are more common than right-sided atrial myxomas. Atrial myxomas can lead to a triad of complications. The most common symptoms are associated with obstruction due to the size and location of the tumor. The next most common symptoms are associated with pulmonary and systemic embolization. Patients may also present with constitutional symptoms. Diagnosis is made via means of transesophageal echocardiography and magnetic resonance imaging. Early diagnosis and surgical resection remain the treatment of choice to prevent complications. Patients usually have a good prognosis after resection.
