The final stage in a double valve replacement is the insertion of the aortic valve. The new valve is then lowered into position and all of the sutures are tied. The aorta is closed up.
Air is removed from the heart and blood is let over back into the heart.
The cardioplegic solution is washed out of the heart and the heart starts up beating by itself. The Foley catheter is removed and the left atrium closure is completed. When the heart is strong enough, it beats out any remaining air. The heart then completely takes over from the heart-lung machine and the cannulae are removed. The chest can now be closed and the operation is complete.
