Z95: Presence of cardiac and vascular implants and grafts

Z95.4: Presence of other heart-valve replacement

There are 4 valves in the heart. These valves ensure that the blood flows in the right direction. So they have to close tightly. They also have to open up fully so that the blood can be properly pumped out of the heart.

One of your heart valves had not worked properly. The heart valve may have been leaky or constricted. You have therefore received a new heart valve. Your new heart valve is made of artificial material or of material from your own body.
