Is calcification of the mitral valve a type of heart disease?
Generally, calcification of mitral valve was part of rheumatic heart disease with long standing mitral stenosis. But rheumatic mitral stenosis is gradually becoming a rarity with lower prevalence of rheumatic fever and its sequelae.
What is a calcified aortic valve?
Calcified Aortic Valve and Mitral Heart Valve Calcification. The heart valves are important structures in the heart and at its junction with the major arteries. By opening and closing at different stages of heart contraction, these valves ensure that blood flows in one direction through the heart.
Does calcification of the aorta require surgery?
Aortic valve sclerosis — thickening and stiffness of the valve and mild aortic calcification — usually doesn't cause significant heart problems, but requires regular checkups to make sure your condition isn't worsening. If the valve becomes severely narrowed (stenotic), aortic valve replacement surgery may be necessary.

How is calcification of the heart valve treated?
Surgical aortic valve replacement (SAVR) has become the most common treatment for severe calcific aortic stenosis in which patients undergo an open-heart surgery to replace their aortic valve with a mechanical or a bioprosthetic valve; in this procedure calcified native leaflets are cut and removed.
How serious is calcification of the aortic valve?
Aortic valve calcification is a condition in which calcium deposits form on the aortic valve in the heart. These deposits can cause narrowing at the opening of the aortic valve. This narrowing can become severe enough to reduce blood flow through the aortic valve — a condition called aortic valve stenosis.
How do you get rid of aortic calcification?
Currently no clinical therapy is available to prevent or reverse this type of vascular calcification. Some possible targets to block and regress calcification include local and circulating inhibitors of calcification as well as factors that may ameliorate vascular smooth muscle cell apoptosis [2].
Can a calcified aortic valve be repaired?
The novel repair technique of calcified bicuspid aortic valve is described, in which the calcified body of the cusps is repaired with autologous pericardium leaving the native free margin and commissures in place for anchoring. The technique has been used in 48 consecutive patients offering excellent early results.

How does a calcified aortic valve affect the heart?
A calcified aortic valve severely disrupts the normal heart functioning and cardiac output. The heart has to compensate by enlarging the muscle of the left ventricle (hypertrophy). The ventricle is now able to pump harder and the pressure within it increases substantially at contraction, significantly above the norm.
When does heart valve calcification occur?
It occurs over decades and is the reason why heart valve calcification is more often seen after the age of 50 years. The longer human lifespan in this day and age means that heart valve calcification is more frequently seen than it was even half a century ago.
How many cusps does an aortic valve have?
When the aortic valve is affected by calcification, it is known as calcific aortic stenosis. This valve has three cusps but in some people it may only be made up of two cusps and this is known as a congenital bicuspid valve.
What is the name of the valve that pumps blood out of the lungs?
Oxygen-rich (oxygenated) blood returning from the lungs empty into the left atrium and then fill into the left ventricle. When the left ventricle contracts in order to push out the blood through the aorta and to the rest of the body, the bicuspid valve between the left atrium and ventricle closes. This valve is also known as the mitral valve.
What causes mitral valve regurgitation?
It can cause regurgitation when the ability to contract and return to its normal position is impaired due to calcification. Furthermore there may be a narrowing as the calcific deposits may prevent the valve from opening fully when the ventricles relax. Mitral valve calcification can, however, affect other aspects of cardiac physiology and serves as a risk factor for other diseases : 1 Calcific deposits may penetrate the heart wall and affect the electrical conduction system of the heart. 2 Calcific deposits may provide a site for blood clot formation ( thrombus) which can later dislodge ( embolus) and lodge in arteries like the carotid artery thereby leading to a stroke. 3 Calcific deposits may provide a convenient site for bacteria to multiply in infective endocarditis.
What valve is used to prevent backward flow?
When the ventricle contracts, the blood flows to the lungs through the pulmonary artery and the tricuspid valve closes to prevent backward flow. The pulmonary valve, also know as the pulmonic valve, lies at the root of the pulmonary artery. When the right ventricle relaxes and prevents backward flow from the aorta.
What is calcified heart valve?
What is a calcified heart valve? A calcified valve, or valve calcification, is the hardening of the valve due to the deposition of calcium salts at the site of wear-and-tear and damage. Heart valves experience significant wear-and-tear throughout life.
What causes mitral valve calcification?
The most common disease that causes mitral valve calcification is rheumatic valve disease. This typically occurs when a streptococcal throat infection affects the valve during youth but will not become evident until adolescence or adulthood.
What does calcified heart valve mean?
Dr. Borger Says: A calcified heart valve is one in which a large amount of calcium has been deposited over many years. Heart valves are normally formed of leaflets that are thin and pliable. When a heart valve becomes calcified, the leaflets become stiff and the valve eventually becomes narrowed (“stenotic”).
What is TAVR surgery?
Dr. Borger Says: Older, high risk patients with aortic stenosis are currently treated with transcatheter aortic valve replacement (TAVR), a revolutionary procedure that is usually performed through the groin and without the use of cardiopulmonary bypass.
What is BAV in medical terms?
Bicuspid aortic valves (BAV) and other valve anomalies result in particularly turbulent blood flow, which is why these patients present with valve calcification at a much earlier age. BAV disease is the most common congenital cardiac anomaly, occurring in 1-2% of the general population. 4.
Why do heart valves calcify?
One particular reason is attributed to the normal wear and tear of the heart valves because of the fact that the heart is the hardest working muscle in the body. In addition, there can be genetic reasons which include congenital valve abnormalities where the valve stiffens later in life. Other factors that contribute to calcification include smoking, diabetes, chronic kidney disease and elevated cholesterol and triglyceride levels. Most valves become calcified by atherosclerosis, which is a process that causes blockages in the arteries of the heart as well as the rest of the body.
What causes calcification in the heart?
Most valves become calcified by atherosclerosis, which is a process that causes blockages in the arteries of the heart as well as the rest of the body.
Which valve regulates the blood that leaves the heart?
The aortic valve, which is the main valve or the “front door of the heart”, regulates all of the blood that leaves the heart and is the valve that calcifies most frequently. It is very unusual for the right- sided heart valves (tricuspid and pulmonary) to calcify and it is not really clear why.
Where are the mitral and aortic valves located?
The mitral valve separates the left upper and left lower chambers of the heart. The aortic valve is located at the top of the left lower chamber of the heart. The mitral and aortic heart valves are commonly affected by two main types of conditions: Regurgitation (leakage of the valve): The ...
What are the valves in the heart?
×. The heart has four valves that ensure blood flows in the proper direction through the heart. The two most commonly discussed heart valves are the mitral valve and the aortic valve. These two valves are located on the left side of the heart. The mitral valve separates the left upper and left lower chambers ...
What causes the mitral valve to not close?
The mitral and aortic heart valves are commonly affected by two main types of conditions: Regurgitation (leakage of the valve): The valve does not fully close, causing blood to flow backward. This forces the heart to pump more blood on the next beat, making it work harder. Stenosis (narrowing of the valve): The opening of the valve narrows, ...
How long do biological valves last?
Biological valves are made from animal tissue (cow or pig). They last approximately 10 to 15 years, and patients do not require long-term blood thinning medications. A biological valve is recommended for those 65 or 70 and older. Learn more about mitral valve repair and replacement.
What is the purpose of ring annuloplasty?
Decalcification to remove calcium and improve valve mobility. Repair of the fibrous strings that support the valves. Ring annuloplasty tightens the ring-like structure (the annulus) that supports the valve by inserting an artificial ring made of metal, tissue or cloth around the valve.
Why does the heart pump blood with increased force?
This causes the heart to pump blood with increased force in order to move blood through the narrowed or stiff (stenotic) valve. “When the mitral and aortic heart valves fail to open and close properly, the heart’s ability to pump blood adequately through the body is hampered. The implications for the heart can be serious ...
Can a faulty aortic valve be replaced?
With aortic valve replacement surgery, the faulty valve is removed and replaced with an artificial valve. As with mitral valve replacement surgery, a damaged mitral valve can be replaced with either a mechanical valve or a biological valve. The decision to choose a mechanical or biological aortic valve depends on the unique needs of each patient.
What is the best treatment for calcification of the heart valves?
The primary option for treatment of calcification of the heart valves is surgery. For certain patients, focused ultrasound could provide a noninvasive alternative to surgery with less risk of complications – such as surgical wound healing or infection – at a lower cost.
How does cavitational focused ultrasound work?
How it Works. Where the beams converge, pulsed cavitational focused ultrasound (or histotripsy) will deliver mechanical energy to the calcium deposits on the valve. This improves blood flow and the valves' ability to open. This is similar to lithotripsy, which is used on kidney stones.
Is there a clinical trial for aortic stenosis?
A clinical trial has been extended in Europe for severe aortic stenosis patients who are not candidates for open aortic valve replacement or transcatheter aortic valve replacement. Initial results from this trial have been published.
Is Cardiawave used for kidney stones?
This is similar to lithotripsy, which is used on kidney stones. Cardiawave is treating patients with aortic stenosis that have calcifications on their aortic valves. The initial use is for patients with severe, symptomatic aortic stenosis patients. This study is believed to be the first in human treatment. Advantages.

Upper lobe vessels are also a little prominent. Calcification of the mitral valve is seen only rarely these days as most persons with mitral stenosis get operated before ...
Can mitral valves be calcified?
Calcification of the mitral valve is seen only rarely these days as most persons with mitral stenosis get operated before the valves become calcified. Only long standing cases unfit for surgery due to other reasons can be noted to have such dense calcification on chest X-ray.
Is mitral valve calcification a rheumatic disease?
Generally, calcification of mitral valve was part of rheumatic heart disease with long standing mitral stenosis. But rheumatic mitral stenosis is gradually becoming a rarity with lower prevalence of rheumatic fever and its sequelae.
What is the condition of a calcified heart valve?
However, if your calcified heart valve causes a condition known as stenosis -- a narrowing of the valve, which impedes blood flow -- then treatment may be necessary. According to MedlinePlus.com, when stenosis occurs, you may need valve replacement surgery.
What tests are used to check for calcified heart valves?
The Cleveland Clinic reports that your physician may also use a variety of tests to identify the calcified heart valve, including echocardiograms, electrocardiograms and cardiac catheterization. The Cleveland Clinic reports that other diagnostic tests such as ultrasounds, computer tomography and magnetic resonance imaging tests can be used.
Why is my heart valve calcified?
Causes of Calcification. Not having enough magnesium in your diet can cause you to suffer from a calcified heart valve. Age also can bring about calcification of your heart valves. In fact, the University of Maryland Medical Center reports that aortic valve calcification is common in people who are older than 75.

Function
- The heart valves are important structures in the heart and at its junction with the major arteries. By opening and closing at different stages of heart contraction, these valves ensure that blood flows in one direction through the heart. There are four main valves in the heart and blood vessels one between the atrium and ventricle on each side (atrioventricular or AV valve) and one in each …
Prognosis
- It is important to remember that any valve can become calcified. However, calcification is more likely to affect the valves on the left side of the heart mitral valve and aortic valve because it experiences greater pressure than the valves on the right side of the heart. Calcification is not an overnight process. It occurs over decades and is the reason why heart valve calcification is mor…
Mechanism
- Studies suggest that the valves may not transform from an otherwise normal valve into a calcified valve over time as it was previously thought. Instead it may undergo several different stages of degenerative changes similar to atherosclerosis. Eventually calcification causes it to harden and narrow. However, in light of these different stages of degenerative changes, it is therefore likely t…
Pathophysiology
- The aortic valve closes when it is filled with blood from the initial backward flow of blood at the end of ventricular contraction (systole). The free margin is usually spared of any calcification but the parts of the cusps near its point of attachment are most affected. These are the flexible parts of the valve that experience the most amount of bending when the cusps open and close. The c…
Clinical significance
- A calcified aortic valve severely disrupts the normal heart functioning and cardiac output. The heart has to compensate by enlarging the muscle of the left ventricle (hypertrophy). The ventricle is now able to pump harder and the pressure within it increases substantially at contraction, significantly above the norm. However, the muscle wall also n...
