Heart Surgery News and Research

RSS

Heart surgery is done to correct problems with the heart. More than half a million heart surgeries are done each year in the United States for a variety of heart problems. Heart surgery is used to correct heart problems in children and adults. This article discusses heart surgeries for adults. For more information about heart surgeries for children, see the Diseases and Conditions Index articles on congenital heart defects, holes in the heart, and tetralogy of Fallot.

The most common type of heart surgery for adults is coronary artery bypass grafting (CABG). During CABG, surgeons use healthy arteries or veins taken from another part of the body to bypass (that is, go around) blocked arteries. CABG relieves chest pain and reduces the risk of heart attack.

Final report from manufacturer KCI indicates greater benefit of NPWT

Negative pressure wound therapy has been used in hospitals for over 20 years; over 100 studies have been completed. However, conclusions on benefit and harm are in part uncertain because study initiators are withholding results.

TAVR procedure safe in patients with unusual valve anatomy

Compared with patients who had a typical tricuspid aortic valve, patients with a more unusual bicuspid aortic valve had a similar rate of death but a higher likelihood of stroke after undergoing a procedure to replace the valve by threading surgical equipment through an artery, according to research presented at the American College of Cardiology's 68th Annual Scientific Session.

Study finds TAVR to be as good as open-heart surgery for patients at low surgical risk

A new trial comparing self-expanding transcatheter aortic valve replacement (TAVR) to standard open-heart surgery for valve replacement—this time in patients with severe aortic stenosis who are considered low surgical risk—found no difference in the combined rate of disabling stroke or death from any cause at two years.
