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.

Prior administration of erythropoietin reduces need for blood transfusions

Anemia increases operative mortality and morbidity in non-cardiac and cardiac surgical procedures. Anemic surgical patients may require more blood transfusions, raising the risk of transfusion-related complications and increasing costs.

Study: Stem cells can communicate with mature heart cells, form electrical couplings

Stem cells drawn from amniotic fluid show promise for tissue engineering, but it's important to know what they can and cannot do. A new study by researchers at Rice University and Texas Children's Hospital has shown that these stem cells can communicate with mature heart cells and form electrical couplings with each other similar to those found in heart tissue.

Catheter-delivered aortic valve durable at three years

All-cause and cardiovascular mortality were similar for transaortic valve replacement compared to open-heart surgery in high-risk older patients at three years with no increased risk of stroke after 30 days, according to results from the PARTNER study presented today at the American College of Cardiology's 62nd Annual Scientific Session.
