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.
