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.

Sema4, Mount Sinai, Sanofi announce launch of new collaborative asthma study

Sema4, a patient-centered predictive health company, and the Mount Sinai Health System today announced the launch of a five-year collaborative study with Sanofi designed to provide new insights into the biological mechanisms and other factors implicated in asthma.

Researchers shed light on molecular mechanisms of heart valvular disease

About three per cent of the world's population is affected by valvular heart diseases. It is also the most common cause of heart surgery, as no drug-based treatment is available.

Study evaluates second-hand marijuana smoke exposure among children

In a study designed to evaluate second-hand marijuana smoke exposure among children--a topic that scientists have not yet widely addressed--researchers at the Icahn School of Medicine at Mount Sinai found that nearly half of children whose parents smoked marijuana showed evidence of second-hand marijuana smoke exposure.

Researchers develop tool that speeds up analysis and publication of biomedical data

Researchers at the Icahn School of Medicine at Mount Sinai have developed a tool that speeds up the analysis and publication of biomedical data from many months or years to mere minutes, transforming the way researchers communicate results of their studies.

Miniature pacemakers aim to make heart procedures for infants less invasive, more efficient

At 2:15 p.m. C.T. on Sunday, Nov. 11, Rohan Kumthekar, M.D., a cardiology fellow working in Dr. Charles Berul's bioengineering lab at the Sheikh Zayed Institute for Pediatric Surgical Innovation, part of Children's National Health System, presents a prototype for a miniature pacemaker at the American Heart Association's Scientific Sessions 2018.

AI in medical space must be carefully tested for performance across wide range of populations

Artificial intelligence tools trained to detect pneumonia on chest X-rays suffered significant decreases in performance when tested on data from outside health systems, according to a study conducted at the Icahn School of Medicine at Mount and published in a special issue of PLOS Medicine on machine learning and health care.

4TECH successfully completes first two implantations of TriCinch Coil tricuspid valve repair system

4TECH Inc., a leader in the field of transcatheter tricuspid valve repair, initiated its U.S. Early Feasibility Study, following receipt of approval from the U.S. Food and Drug Administration, with the successful first two implantations of the TriCinch Coil System at Piedmont Heart Hospital, Atlanta, Georgia, by Dr. Christopher Meduri, Dr. Vivek Rajagopal and Dr. Mani Vannan.

Researchers find key differences in brains of males and females with schizophrenia

Researchers from the Icahn School of Medicine at Mount Sinai have found clear disparities in the way males and females--both those with schizophrenia and those who are healthy--discern the mental states of others.

Individual heart cells respond differently to high blood pressure

A team of cardiologists have found that single cells within the heart are affected by high blood pressure in different ways. Some adapt, whilst others fail.

Individual cells within the same heart cope differently with high blood pressure, study shows

Individual cells within the same heart cope differently with high blood pressure, according to a study in human cells and mice by a team of cardiologists and computational biologists at the University of Tokyo.

People overestimate benefits and underestimate risks of medical procedures, shows research

From major heart surgery to a course of minor drugs, people overestimate the benefits and underestimate the risks of a variety of medical procedures, according to new research.

Researchers explore whether open heart surgery affects cognitive abilities

Most people who need open heart surgery to repair damaged heart valves are aged 65 or older. The American Heart Association estimates that nearly 8 million people have had heart surgeries.

Computational model helps predict immune response in patients undergoing heart surgery

A research team led by Peter Sloot, professor of Complex Adaptive Systems at the UvA, has managed to pinpoint the mechanisms behind the immune response triggered in patients undergoing open heart surgery.

Day of discharge after heart surgery does not affect hospital readmissions

Despite a common belief that weekend and holiday discharge after major heart surgery may impact hospital readmissions, research published online today in The Annals of Thoracic Surgery showed that day of discharge does not affect readmissions.

Researchers design modeling system to infer relationships between genes, drugs, and their environment

A team of researchers at the Icahn School of Medicine at Mount Sinai and the University of Washington has designed a modeling system that integrates genomic and temporal information to infer causal relationships between genes, drugs, and their environment, allowing for a more accurate prediction of their interactions over time.

Study: Mastectomy does not completely eliminate need for future breast imaging

The proportion of breast cancer patients who are eligible for breast conservation therapy, yet opt for mastectomy, is increasing, for reasons that include the desire to eliminate future screening and/or biopsy of the remaining breast tissue.

Excessive use of erectile-dysfunction medication could lead to long-term vision problems

In a first-of-its-kind study, Mount Sinai researchers have shown that color vision problems caused by retinal damage on a cellular level can result from a high dose of sildenafil citrate, the popular erectile-dysfunction medication sold under the brand name Viagra.

TEAD1 protein appears to be important regulator of tumor migration in glioblastoma

A specific protein called TEAD1 is an important regulator of tumor migration in glioblastoma, the most common brain tumor in adults, and deactivating this protein may stop tumor cells from migrating away from the main tumor mass, according to research conducted at the Icahn School of Medicine at Mount Sinai and published October 1 in the journal Nature Communications.

New project aims to develop strategies for more durable animal-derived heart valves

Animal-derived heart valves are preferred to mechanical ones for valve-replacement heart surgery because they are more biocompatible and do not require a life-changing regime of anticoagulant drugs.
