2 Vital Reasons Explaining Why Mitral Valve Surgery Is Needed


Undoubtedly, the heart is the most indispensable part of human body which plays a vital role in giving life to it by pumping blood to the lungs and other parts of the body. It is an extremely hard-working organ that keeps on maintaining the flow of blood throughout the body; even a slight disorder in its functionality can result in a number of problems which may sometime prove fatal.  We all know well that heart comprises four major valves, each one responsible for supplying a specified quantity of blood to major arteries; one valve among them is the mitral valve which is found on the left side of the heart.


Blood generally flows right to left, i.e. from right upper chamber to right lower chamber, then to lungs to the left atrium and moving through mitral valve it goes into the left ventricle and then to other organs of the body; this cycle goes on continuously till the last breath of a person.

As mitral valve lies in between left atrium and ventricle, it regulates the flow of blood between the two chambers and thus plays a vital role in blood circulation cycle. If due to any reason it starts malfunctioning, the entire cycle will get disturbed causing lots of complications sometimes leading to death. These days heart-related diseases are occurring frequently which many times lead to the fatality of a person; one among them is related to the mitral valve. The solution to mitral valve malfunctioning is mitral valve surgery.

In this surgery, the mitral valve is either repaired or replaced in case of severe damage. Let us have a look, in what kind of situations this surgery is used or what are the reasons which compel a person to go for this surgery.

  • Backflow problem (Regurgitation)

Backflow problem, also known as regurgitation, is the most common disorder that occurs when two leaflets of valve fails to seal the opening between the left atrium and left ventricle successfully (also known as leaflet prolapse), causing blood leakage from one chamber; this gives birth to the backflow problem, ultimately leading to the valve failure. This sometimes increases lungs pressure eventually causes heart failure too.

Remedy to get rid of this problem:

Sewing the cleft: By far, we have seen that regurgitation is caused due to blood leakage or blood flow disorder through cleft; the most viable option to get resolved this issue is to sew the cleft simply thereby preventing the leakage.


Another approach to chuck out this problem is annuloplasty. You might have known that the valve’s leaflets are naturally attached to the heart by a ring-shaped annulus; so in this methodology, the surgeon attempts to provide support for the leaflets by putting an artificial ring in the region of the annulus.

  • Stenosis

Stenosis, though occur rarely, is another vital reason which compels a person to go for mitral valve surgery. This problem is generally found in patients who have ever suffered from rheumatic fever in their childhood. Actually, this fever affects the immune system of the patient and attacks the mitral valve’s leaflets making them stiffen and thicken; this, in turn, restricts the leaflets to open as widely as they should. This incapability confines the blood flow from the left atrium to the left ventricle resulting in the rise of blood pressure; this in turn sometimes leads to blood clots and even heartbeat stoppage.

Remedy Mitral Commissurotomy:

As we came to know from above paragraph that stenosis occurs due to a congenital defect or rheumatic fever which results in valve’s flaps to fuse together, that in turn hinders blood flow and sometimes prove life threatening too. This can be resolved through mitral valve open surgery procedure namely mitral commissurotomy.

This could be performed in two ways:

Cutting through the breastbone:

Catheterization From the above paragraphs, you might have come to know that it is the disorder or deregulation of blood flow which creates so much complexity and compel a person to go for mitral valve surgery. This is an effective approach that sort out the disorder in blood circulation and increases the survival chances of a patient providing them an improved lifestyle.
