Q

What two heart conditions are found in Lutembacher Syndrome?

A

1. Mitral Stenosis

2. ASD

Lutembacher syndrome is defined as a combination of mitral stenosis and a left-to-right shunt at the atrial level. Typically, the left-to-right shunt is an atrial septal defect (ASD) of the ostium secundum variety. Both these defects, ASD and mitral stenosis, can be either congenital or acquired
