Diagnosis of cardiac myxoma is typically suggested in the presence of symptoms and echocardiographic findings of an intracardiac mass and confirmed histologically. Coronary angiography (CA) and cardiac magnetic-resonance-imaging (MRI) may provide specific additional information which could lead to a precise preoperative diagnosis. ... In patients with a cardiac mass, echocardiography remains the first diagnostic imaging modality but does not allow definite discrimination between cardiac tumors and thrombi. CA shows neovascularization in 50% and has, therefore, a low sensitivity and specificity in distinguishing the nature of the mass. MRI shows specific tissue characteristics facilitating the diagnosis of myxoma preoperatively. Surgery should be performed promptly and this can provide excellent early and mid-term results.
