The National Institutes of Health has awarded the Icahn School of Medicine at Mount Sinai an $8.5 million renewal grant to continue groundbreaking work aimed at understanding and improving long-term outcomes for children with congenital heart disease—the most common type of birth defect in the United States.

In a world-first, a team of researchers at the National Institutes of Health (NIH) and Emory School of Medicine, Atlanta, has successfully performed a coronary artery bypass — a normally open-heart surgery — without cutting the chest wall. The team employed a novel intervention to prevent the blockage of a vital coronary artery, which is a very rare but often lethal complication following a heart-valve replacement. The results suggest that, in the future, a less traumatic alternative to open-heart surgery could become widely available for those at risk of coronary artery obstruction.
