How Is It Treated?

In AV Septal repair, the ventricular and atrial septal defects are closed with patches (or a single patch) made of a synthetic material. The malformations of the valves are repaired by suturing to the patched atrial and ventricular septa, which separate them.

In cases where the mitral and tricuspid valves are connected, forming a single opening, the patch of the ventricular septal defect is used to divide the two valves, which are then reduced in size by suturing.

In the animation at left, a single patch (shown in pink) is used to close the ASD and VSD and to divide the mitral and tricuspid valves (See also animation on this page).
