There are two main types of prosthetic valves. They are-
 Bioprosthetic valves lasts about 10-15 years. These are usually obtained from animals or human organ donors. Human Valves are referred as Homograft or allograft. Valves from pigs (porcine) or cows (bovine) can be used and are referred as heterograft or Xenograft. Both these valves have a metal wire or stent in the middle and have a similar design. Stentless valves are also present but are hard to implant. Tissue valves seem to improve the patient’s hemodynamics, but tend to stiffen in 10-15 years and calcify causing a stenotic valve. An organ donor’s valve is cryopreserved in liquid nitrogen and used when there is a requirement for the valve. Patients’ chances of rejecting the valve are low. It shows good durability and hemodynamics. Mechanical valves are purely metal and lasts a lifetime. Complications of blood clots and emboli are common in patients with a mechanical valve. So patients take Coumadin or blood thinners all their life. The most commonly used valve in the United States is a bileaflet valve called as “ST. Jude”. Incidence of thrombosis in this valve is low. “Starr-Edwards” is a caged ball valve, which has very long durability but high incidences of thromboembolism. Since 1952, 30 different valves have been used worldwide and the recent one being a bileaflet valve. The bileaflet valve does not close completely and allows back flow of blood to an extent and therefore is not ideally used. TTK chitra valve is the only Indian made valve. It is a tilting disc valve, durable and highly cost effective. |

Posted on: 02/19/2011 Patients undergoing mitral valve replacement are susceptible to the following risks. Bleeding, infection, complex reaction to anesthetic. The risk involved in most cases can be determined by the physician and it depends on a variety of factors such as the patient’s age, general condition, specific medical problems and heart functions.

Posted on: 02/19/2011 Alternative treatment is Balloon valvuloplasty.Balloon valvuloplasty is performed using a catheter, i.e. a very thin flexible tube which can be inserted into the body, with a balloon at the end. The balloon is put inside the valve and is expanded thus stretching the valve and bringing it back to its normal size. For more info: heart-consult.com/articles.
