Problems with the Walls

1. Atrial Wall

Problem: Atrial Septal Defect

The wall between the right atrium and left atrium is called Atrial Septum. Please note that the word "septum" in Greek means "wall."

A hole between the two atriums called an Atrial Septal Defect (ASD). When the blood coming back from the lungs to the Left Atrium crosses the ASD it mixes with the blue blood coming back from the body in the Right Atrium

Fix: Patch Operation

Doctors fix an Atrial Septal Defect (ASD) by patching the hole between the two atriums.

2. Ventricular Wall

Problem: Ventricular Septal Defect

The wall between the front two chambers (between the two ventricles) is called Ventricular Septum.

A hole between the two ventricles is called a Ventricular Septal Defect (VSD). When the pink blood in the Left Ventricle crosses the VSD it mixes with the blue blood in the Right Ventricle.

Fix: Patch Operation

Doctors fix a Ventricular Septal Defect (VSD) by patching the hole between the two ventricles.
