Where are LA Myxomas typically attached?

Myxomas, particularly left atrial myxomas, are typically attached to the interatrial septum. This location is significant because the interatrial septum is the wall that divides the left and right atria of the heart, and myxomas often arise from this area. The septal attachment allows the myxoma to grow into the left atrium, which can lead to various clinical manifestations, including obstruction of blood flow or embolic events when small pieces break off and travel to other parts of the body.

Understanding the anatomy of the heart is crucial when diagnosing and managing cardiac tumors like myxomas. They are most commonly found in the left atrium and are usually an isolated mass, and their characteristic attachment to the interatrial septum is a key feature that aids healthcare professionals in confirming a diagnosis during imaging studies such as echocardiography.
