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.

MRI measurements of scar tissue accurately predict the risk of arrhythmia-related sudden death

Using magnetic resonance imaging (MRI) scans of the heart wall, researchers at Johns Hopkins have found that people whose muscle wall thickness contained more than 25 percent scar tissue were approximately nine times more likely to test positive for a fast and dangerous heart rhythm known as ventricular arrhythmia.

New device offers potential for accurate and reliable monitoring of brain oxygenation during cardiac surgeries

A new device that uses near-infrared light to non-invasively monitor the oxygenation of the brain during surgery appears to be a promising alternative to the more invasive techniques currently in use, according to a new study by Duke University Medical Center anesthesiologists.

Surgery to treat obesity far more risky for men

Researchers say that using stomach-shrinking surgery to treat severe obesity is riskier than previously thought for men, the elderly and people with conditions such as hypertension.

Large scale study to see if angioplasty can be safely performed in small hospitals

Cardiologists at Johns Hopkins have launched a nationwide study of more than 16,000 patients to see if a potentially life-saving procedure called angioplasty can be safely performed in smaller, community hospitals, easing access to the therapy for patients. Researchers expect to enroll the first study patients in early fall 2005.

Aspirin shown to be beneficial before heart surgery

Surgeons who have been advising their patients to avoid taking aspirin in the days before surgery because they feared it could cause bleeding, will be reassured by the results of a new study.

Ways to avoid hazards of heart bypass under study

The heart-lung bypass machine that stills the heart while surgeons bypass an adult’s clogged arteries or repair a baby’s malformed heart can also trigger a potentially deadly inflammatory response.

Inflammation plays an important role in post-operative stroke

Duke University Medical Center researchers have discovered that patients who have two specific gene variants are more than three times as likely to suffer a stroke after heart surgery.

Coronary angioplasty increases risk of developing Alzheimer's disease

Boston University School of Medicine (BUSM) researchers have discovered that patients who have either coronary artery bypass graft surgery or coronary angioplasty are at an increased risk of developing Alzheimer's disease.

Researchers test experimental drug Neuprex on infants undergoing heart surgery

UT Southwestern Medical Center is the only institution in the nation approved by the Food and Drug Administration to test an experimental drug on infants undergoing heart surgery to see whether it can help them avoid potentially lethal infections and improve survival.

Heart surgery safe and successful for many 80 year olds

According to a new report, cardiac surgery can be safely performed in octogenarians and may improve their life expectancy.

Heparinase I is not a suitable replacement for protamine

The results of an international clinical trial led by Duke University Medical Center researchers has shown that a new drug is not a suitable replacement for protamine, a drug that has been used for more than 40 years after coronary artery bypass surgery to return thinned blood to its normal state.

Healing touch, music, relaxation a plus for heart surgery patients

According to a newly released study people who learned about relaxed breathing and received soothing touch and music before heart surgery were more likely to be alive 6 months after the procedure.

Study finds better long-term outcomes when surgeons place a bypass graft to all the territories of the heart that have significantly blocked arteries

Pointing out that not all coronary artery bypass operations are performed the same way or have equivalent outcomes, cardiothoracic surgeons at Cedars-Sinai Medical Center have found that patients who have blockages of multiple coronary arteries and undergo "complete revascularization" - grafting of arteries to restore blood flow to all affected territories of the heart - have consistently better long-term survival rates than those who have "incomplete revascularization."

Private health insurance given the go-ahead in Canada

A Quebec law that banned some private health insurance, has been overruled by the Supreme Court of Canada and is a decision which is likely to pave the way to a greater use of private health care to supplement a crumbling public system.

Atrial fibrillation may soon have an effective treatment

In laboratory tests in dogs, cardiac researchers at Washington University School of Medicine in St. Louis have found that treatment with anti-inflammatory drugs after heart surgery may lessen or prevent atrial fibrillation. They report their findings in the June 7 issue of Circulation.

New study shows that bypass surgery is more successful than stents in heart surgery

A study of nearly 60,000 patients has found that people with several clogged heart arteries did better if they had bypass surgery rather than a less-drastic procedure in which the blood vessels are propped open with tiny mesh cylinders called stents.

Increase in heart surgery mortality from SSRIs or depression?

Duke University Medical Center researchers have found that patients who were using a class of anti-depression drugs known as selective serotonin reuptake inhibitors (SSRI) prior to undergoing coronary artery bypass surgery have significantly higher death and rehospitalization rates up to five years after the procedure than patients who were not on SSRIs.

Specific variants of genes predict bleeding after heart surgery

Duke University Medical Center researchers have found that the presence of specific variants of genes that control clotting and the contractility, or "tone," of blood vessels can double the ability of physicians to predict those heart surgery patients at greatest risk of bleeding after surgery.

Can hospital data detect poor performing doctors?

For over 20 years, routine data sources such as the hospital episode statistics have been widely perceived as being of little value because of problems with completeness and accuracy, and the Department of Health has in the past dismissed their use for identifying poor quality services.

Technology helps Stanford shed new light on coronary bypass surgery

On March 31, Joel Dyels celebrated his 72nd birthday by having coronary bypass surgery at Stanford Hospital. He also became the third patient at Stanford - and in the United States - to benefit from a new imaging system that lets doctors see the blood pathways they have created while the patient's chest is still open.
