Cardiac tumors can be primary (benign or malignant) or metastatic (malignant). Myxoma, a primary benign tumor, is the most frequent type. Cardiac tumors can be localized in any cardiac tissue and cause valvular or tract obstruction of entry or exit, thromboembolism, arrhythmias or pericardial disorders. The diagnosis is based on the results of echocardiography, and often cardiac MRI. The treatment of benign tumors is usually their surgical resection, although they may recur. The treatment of metastatic cancer depends on the type and origin of the tumor and the prognosis is usually unfavorable.
