Overview

There are no hallmark findings in cardiac myxoma. However, clinical features of cardiac myxoma are determined by tumor location, size and mobility. Symptoms may occur at any time, but most often they tend to occur with changes in body position. A positive history of systemic embolism and heart failure may be suggestive of cardiac myxoma. The most common symptoms of cardiac myxoma include chest pain, syncope, and dyspnea on exertion. About 20% of cardiac myxomas are asymptomatic at the time of diagnosis.

History

Common Symptoms

Symptoms associated with cardiac myxomas are typically due to the effect of the mass of the tumor obstructing the normal blood flow within the heart chambers. Left atrial myxoma symptoms may mimic mitral stenosis, while right atrial myxomas rarely produce symptoms until they have grown to be at least 13 cm wide. General symptoms may also mimic those of infective endocarditis.[3]

Clinical features can be categorized as:[4][5][6]

Valvular obstruction

Embolic event

  • Distribution will depend on location of tumor
  • Most are left sided, and therefore most are systemic (brain or extremities)

Constitutional symptoms

Less Common Symptoms

Less common symptoms may include:[7][8]
