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.

NIH program provides a real-time risk assessment of variants of SARS-CoV-2

Faculty from the Departments of Microbiology, Medicine Genetics and Genomic Sciences, and Pathology and Molecular Cell-Based Medicine at the Icahn School of Medicine at Mount Sinai play key roles in a National Institutes of Health (NIH) program set up to provide a real-time risk assessment of variants of SARS-CoV-2, the virus that causes COVID-19. The program, called SARS-CoV-2 Assessment of Viral Evolution (SAVE) and described in a paper published March 31 in Nature, assesses how the variants might affect transmission, virulence, and resistance to both disease-induced (convalescent) and vaccine-induced immunity.
