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.

Newly released national framework identifies obstacles to improving EMS systems

As part of nationwide efforts to improve emergency medical care, researchers at the Mount Sinai Health System, in collaboration with UC San Diego Health, have released a national framework report titled "Promoting Innovations in Emergency Medical Services" that identifies regulatory, financial, and technological obstacles to improving local and state EMS systems.

Researcher explore why some patients recover quickly after surgery while others don't

Why do some patients recover quickly after surgery, while others don't? That is an important question when treating older frail patients suffering from aortic stenosis. Lead author Dae Hyun Kim, M.D., M.P.H., Sc.D., and principle investigator Director Lewis A. Lipsitz in the Marcus Institute for Aging Research at Hebrew SeniorLife explore this question in a paper published today in the Journal of the American Medical Association Internal Medicine.

Meta-analysis of adults with autism shows large impairments in key cognitive domains

The first comprehensive, systematic review and meta-analysis of adults with autism shows that despite having an intact IQ, these adults have medium to large impairments in four key social- and non-social cognitive domains: theory of mind, emotion perception and knowledge, processing speed, and verbal learning and memory.

Kidney disease risk gene found in more populations than previously known

In the largest population genomics investigation to date, a team of researchers at the Icahn School of Medicine at Mount Sinai, Stanford University, and the University of Colorado have discovered that kidney disease risk variants of the gene APOL1, previously known to affect African and African American populations, are also found at appreciable frequencies in Caribbean and Latin American populations.

Whole genome study identifies genetic architecture for diagnosis of polycystic ovary syndrome

In the largest genetic analysis of polycystic ovary syndrome (PCOS) performed to date, an international consortium, including researchers at the Icahn School of Medicine at Mount Sinai, conducted a whole genome association study to identify common genetic architecture for different diagnostic criteria used to define the syndrome.

Study finds how pyruvate helps improve cardiac output in pediatric patients with LCOS

Can pyruvate, the end product of glycolysis, help improve cardiovascular function in children who have cardiopulmonary bypass surgery and suffer from low cardiac output syndrome? This question is one that Rafael Jaimes, Ph.D., a staff scientist at Children's National Heart Institute, a division of Children's National Health System, is studying, thanks to a two-year grant from the American Heart Association.

Novel 3D printing workflow helps predict leaky heart valves

More than one in eight people aged 75 and older in the United States develop moderate-to-severe blockage of the aortic valve in their hearts, usually caused by calcified deposits that build up on the valve's leaflets and prevent them from fully opening and closing.
