VALVE REPLACEMENT SURGERY
Valvular heart disease is a form of heart disease that 
occurs when one or more of the heart’s four valves 
don’t function properly. Valve replacement surgery may 
be an option if the valves of your heart are too fragile, 
scarred, or otherwise damaged to repair.
REASONS FOR REPLACEMENT
The valves of the heart are responsible for allowing 
nutrient-rich blood to flow through the chambers of your 
heart. Each valve is supposed to close completely after 
ushering in blood flow. Diseased heart valves aren’t 
always able to perform the job as well as they should.
The signs of valvular heart disease can include:
•fatigue
•dizziness
•lightheadedness
•shortness of breath
•cyanosis
•chest pain
•fluid retention, especially in the lower limbs
TYPES OF VALVE REPLACEMENT SURGERY 
Aortic Valve Replacement:-
The aortic valve is on the left side of the heart and serves as an outflow 
valve. Its job is to allow blood to leave the left ventricle, which is the 
heart’s main pumping chamber.
Survival rates depend on:
•your age
•your overall health
•other medical conditions you have
•your heart function.
Mitral Valve Replacement:-
The mitral valve is located on the left side of the 
heart. It serves as an inflow valve. Its job is to 
allow blood from the left atrium to flow into the 
left ventricle. Surgery may be required if the 
valve doesn’t fully open or completely close.
The following also play a role in survival rate:
•your age
•your overall health
•other medical conditions you have
•your heart function
Double Valve Replacement
A double valve replacement is a 
replacement of both the mitral and the 
aortic valve, or the entire left side of the 
heart. This type of surgery is not as 
common as the others and the mortality 
rate is slightly higher.
Pulmonary Valve Replacement
The pulmonary valve separates the 
pulmonary artery, which carries blood to the 
lungs for oxidation, and the right ventricle, 
which is one of the heart’s chambers. Its job 
is to allow blood to flow from the heart to 
the lungs through the pulmonary artery. The 
need for pulmonary valve replacement is 
usually due to stenosis, which restricts blood 
flow. Stenosis may be caused by a congenital 
defect, infection, or carcinoid syndrome.
