A<unk>  is generally considered pathologically benign, however outflow obstruction or embolism can be associated with syncope, chest pain, heart attack, stroke and sudden cardiac death. Symptoms due to<unk> s are generally due to either mechanical effects of the tumor or due to embolization of a portion of the tumor to a distal organ. In particular, chest pain or syncope may be due to transient occlusion of the left main coronary artery by the tumor, while a heart attack or sudden cardiac death may be due to embolization of a portion of the tumor into a coronary artery.
