Award for TTK Chitra heart valve prosthesis

TTK Healthcare and Chitra Tirunal Institute for Medical Science and Technology have bagged the..National award for successful commercialization of indigenous technology 2001 for developing artificial heart valve prosthesis...It is a tilting disc valve design incorporating a metallic housing, which is integrally machined from a cobalt based wrought alloy. The circular disc inside is made of ultra...

Defective heart valve causes problems

According to researchers, a recent study shows that a leaky heart valve raises the risk of abnormal heart rhythms. In atrial fibrillation (AF) the upper chambers of the heart beat randomly and unsuccessfully. The condition is linked to heart attack and stroke.// Researchers at the University of Texas, have now shown that having a leaky heart valve - separating the upper and lower heart chambers...

Cardiac Valve Disease Linked To Genes

A new study suggests that death from cardiac valve disease might be predominant in certain families. Researchers analyzed // death certificates and genealogy data of people who died of aortic and mitral valve disease . ..Results show deaths from nonrheumatic mitral and aortic diseases are clustered among close and distant relatives, which suggests a genetic link. Deaths from these conditions be...

Mutations in NOTCH1 cause an early developmental defect in the aortic valve

Dr. Srivastava and his colleagues of UT Southwestern Medical Center of Dallas// discovered that the mutation in a gene NOTCH1 is responsible for aortic valve disease. Aortic valve disease is a common heart birth defect which causes adult heart disease. ..The study was done in five generations of a Dallas family; the researchers studied the DNA mutations in all the 11 members of the family who we...

Heart valve surgery may be replaced by new heart therapy

The most common heart problems among the old people are those involving the mitral valve(that which controls the flow of blood between the two left chambers of the heart) and the aortic valve(that which controls the flow of blood into the heart). Until now, surgeons surgically replaced the damaged valve in these patients by opening the breast bone. However, a recent discovery// of a new procedure...

Percutaneous aortic valve replacement- a revolution in Cardiac Surgery

The aortic valve in the heart is the valve that governs the flow of blood into a large blood vessel namely the aorta, which supplies blood to various organs of the body. // It prevents the blood from flowing back inside the heart from the rest of the body. ....The effective functioning of the heart depends on the proper functioning of the aortic valve. The aortic valve can be defective in some ca...

Laboratory Heart valve to study Heart diseases

Researcher Grande-Allen is developing a laboratory heart valve which could be used in testing the action of drugs on heart valves in an invitro model. // This new bioreactor heart valve would help in breaking the etiology behind the cause of heart valve disease. ....Research on the laboratory heart valve is funded with $750,000 from NIH and the researchers have found the difference in biochemica...

ResQ-Valve With CPR In Cardiac Arrest Patients To Be Assessed By National Study

It has been proposed by researchers at Medical College of Wisconsin to conduct a large-scale clinical trial to assess the improvement in survival rate in cardiac arrest patients, given CPR and ResQ-Valve//. ....The study would be funded by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health. The ResQ-Valve Study offers a promise in the emergency manag...

Valve Disease Study Suggests New Public Health Concern

Research from Mayo Clinic estimates that about 5 million adult Americans have moderate or severe heart valve disease as a consequence of aging, according to a Mayo Clinic study// published online in The Lancet. ....While rheumatic fever was previously the main cause of valve diseases and was a major public health issue even in the middle of the 20th century, rheumatic fever is not a serious conc...

First Keyhole Heart Valve Surgery Scheduled in Britain

Heart surgeons are getting ready for the first heart valve replacement operation in Britain using key hole technique. // ....The operation is scheduled for Tuesday and will be performed by Jan Kovac and a team of cardiologists. The surgery is termed as percutaneous aortic valve replacement. This technique called the key hole technique was first performed in France. .... The novelty of this surge...

"Umbrella" Valve Provides Potential Alternative to Lung Surgery

A new umbrella-like valve may help patients with emphysema breathe easier and may ultimately provide a noninvasive alternative to lung reduction surgery. // In a new study presented at CHEST 2006, the 72nd annual international scientific assembly of the American College of Chest Physicians (ACCP), the IBV? Valve, a nonsurgical, investigational device, was shown to be safe and effective for patie...

Cancer Patient’s Life Improved With Anti-reflux Valv

An anti-reflux valve developed to help esophageal cancer patients also has been shown to help those with bile duct obstruction, according to a research//. The study, using the anti-reflux biliary stent in patients with cancer of the pancreas or bile duct, appears in the May issue of Gastrointestinal Endoscopy journal. ....This bile duct stent with the “Dua Anti-Reflux Valve,” named after its in...
