Left Atrial Myxoma

Myxomas are the most common primary, benign cardiac tumors occurring. They typically occur in middle-aged adults with a higher incidence in women. Most commonly, myxomas are located in the left atrium (LA). Large myxomas can cause obstruction of the mitral inflow leading to hemodynamic changes similar to mitral stenosis. Smaller myxomas tend to be friable and more likely to cause cardioembolic sequelae such as strokes.
