Overview
Cardiac myxomas are classified by the World Health Organization (WHO) histological classification of tumors of the heart, as "Benign tumors and tumor-like lesions" and categorized into a type of pluripotent mesenchymal tumor.
Classification
- Based on the location and biological behavior of symptoms, cardiac myxomas may be classified into two groups: typical and atypical. In typical cases, cardiac myxomas are almost always single, and there is a striking predilection for the left atrium, with approximately 75-86% occurring there.[1][2][3]
- In atypical cases, presentation is usually early and multicentricity is more common. They are more frequently located on the right side of the heart (38%), or in the left ventricle (5%). There is also recurrence after surgical excision (12%–22%) and an association with other conditions, such as the Carney complex.[1]
- Cardiac myxomas are anatomically distributed, as following:[1]
- Atria (95%)
- Left (75%)
- Right (20%)
- Ventricles (5%)
- Atria (95%)
- There is no established histological differentiation between both type of cardiac myxomas (typical and atypical).[4]
