Highlights & Basics
- Atrial myxoma is the most common of the rare benign primary cardiac tumors.
- Usually found in the left atrium and typically attached to the septum.
- Most common presentation is with symptoms of mitral valve obstruction, followed by embolic manifestations. Constitutional symptoms include fever, fatigue, and weight loss.
- The only definitive treatment is surgical.
