Heart Valve Surgery - A New Minimally Evasive Procedure
Every 12 months about 200, 500 patients in the particular United States will need a new coronary heart valve since they have got severe aortic stenosis. This is a condition in which the aortic valve starts to be able to narrow and affect the efficient blood circulation from the coronary heart to the other parts of the body. This can cause congestive heart failure plus sudden death.

Open-heart surgery is a very popular procedure for many of these heart patients. But also for some who will be too old, also sick or may have had chest surgery before, this kind of is not the option.

A less invasive procedure is usually now available intended for these patients. The doctor needs to mount a valve about a catheter then insert it in the patient's groin or perhaps chest and line it towards the heart.

This strategy does not need stopping the cardiovascular and placing typically the patient over a heart-lung bypass machine, therefore weaker or sicker patients can withstand the procedure. Without valve replacement, the life span expectancy of patients with severe aortic stenosis is typically less than five many years.

This two-hour procedure to replace the broken aortic valve with a 'stent-supported valve' was pioneered within France in 2002. In February 2009, Singapore became typically the first country in Asia to perform it.

Since then, five elderly patients have undergone this kind of procedure at the particular Singapore General Hospital's National Heart Middle. cardiology clinic is recommended just to most patients who have not any other options or perhaps who are struggling from narrowed-valve symptoms like heart problems and even breathlessness.


This procedure is still relatively new and exactly how long the valve will last plus the long lasting outcomes are still mysterious. Comparatively the manufactured valves used throughout conventional open-heart surgery lasts 10 to be able to 20 years. For this reason, the hospital is just not advertising the procedure in order to younger patients and those who are suitable for standard surgical treatment.

There are in addition risk factors and even a patient undergoing such procedure could die from your punctured blood vessel.

The particular success rates in this transcatheter technique within USA and Europe have been documented being 90%.

The conventional valve charges about US$3000 although the new device is almost 10 times more, nevertheless this is expected to be reduced in time.

With an ageing population, the center centres in Singapore are expected to treat an increasing number of patients using valve problems.
