Heart valve repair or replacement procedures are performed by our team of professionals to improve your heart circulation by fixing the existing heart valve or replacing it with a mechanical (man-made) or porcine (pig) valve. This surgery may be done in combination with coronary artery bypass surgery.

Diagnosis and treatment of heart valve disease
There are four valves in the heart that open and close to regulate the blood flow through the heart: aortic valve, mitral valve, tricuspid valve and pulmonic valve. Each heart valve has two or three sections called leaflets. Treatment of heart valve disease includes careful monitoring, medical therapy or heart valve surgery (repair or replacement).
Our cardiologists will diagnose heart valve disease after a careful examination and diagnostic tests.
The aortic valve is between the heart’s lower chamber on the left side of the heart and the aorta, which sends blood to the body. The two diseases of the aortic valve are aortic stenosis and aortic regurgitation. Aortic valves can become thick and narrowed (stenosis), and not able to open completely. Aortic regurgitation happens when leaking occurs due to irregular valve edges (aortic valve regurgitation or insufficiency), causing backflow of blood into the left ventricle due to incomplete valve closure.
The mitral valve is between the heart's upper-left chamber (atrium) and the heart's lower-left chamber (ventricle). A narrowing of the mitral valve is called stenosis (mitral stenosis). The valve will not open all the way and blood flow between the left chambers of the heart is decreased. This can be caused by rheumatic heart disease.
Diagrams of the heart
When the mitral valve does not close completely, that is called regurgitation (or mitral regurgitation). This causes blood to leak or flow backward in the heart on the left side. This happens when part of the valve flops back (prolapse). Usually this is mild but can develop into a severe condition. This can happen over years and you may not know you have this disease until you have symptoms of heart failure.
When surgery is needed
The most common reason for surgery is aortic stenosis (narrowing of the aortic valve opening), and valve replacement is commonly necessary. The second most common reason is mitral regurgitation. (the mitral valve leaks), and the majority of the time the valve can be repaired. The HealthEast Heart Care physician team has extensive experience with mitral valve repair.
Heart valve repair & replacement surgeries
When surgery is needed for heart valve stenosis (narrowing), the valve is most often replaced with an artificial valve. Sometimes a narrowed valve can be repaired in surgery by cutting and shaving back the misshapen leaflets.
Heart valve replacement requires removing the diseased valve and replacing it with a prosthetic (artificial) valve that is sewn into the opening of the natural valve. This can be done with either a mechanical valve or a biological valve.
Replacement valve types
- Mechanical valves are made of synthetic carbon material. These are sturdy and last for many years. Blood can stick to mechanical valves and cause blood clots. If you have a mechanical valve, you will need to take blood-thinning medicines (anticoagulants) for the rest of your life, but the mechanical valve will also last the rest of your life.
- Biological valves are made from animal tissue or come from a donated human heart. Sometimes your own tissue can be used for valve replacement. If you receive a biological valve, you will not need to take blood-thinning medicine unless other conditions are present. Biological heart valves do not last as long as mechanical heart valves and may need to be replaced later after an average of 15 to 18 years of artificial valve function.
HealthEast is proud to offer one of the most promising recent advances in cardiac care to our patients. Transcatheter aortic valve replacement (TAVR) allows treatment of severe aortic stenosis without the need for open heart surgery. This results in patients having shorter recovery times while having their aortic valve replaced with lower risk. The team at HealthEast is among the most experienced in the Twin Cities and is leading the way in the East Metro by introducing the latest generation of heart valves to the area.
