Catheter ablation for chronic atrial fibrillation improves quality of life

People who have endured the effects and risks of an irregular heartbeat for years can get long-lasting relief from a procedure that takes less than two hours, a definitive new study shows.

Biosense Webster receives FDA approval for technology to treat heart rhythm disease

The U.S. Food and Drug Administration (FDA) today approved an innovative combination of technologies that will enhance a doctors' ability to treat patients with abnormal heart rhythms (cardiac arrhythmias).

European markets for cardiac catheterisation imaging systems

With a sharp increase in the incidence of cardiovascular disorders and mortalities in Europe, the need for early detection as well as cardiac interventional procedures has created enhanced scope for the uptake of cardiac catheterisation imaging systems.

Implantable defibrillators benefit women as much as men after heart attack

Women who have had a heart attack get as much survival benefit as men from implanted cardioverter defibrillators (ICDs), devices designed to monitor the heart's pumping rhythm and shock it back to normal when needed, according to a study published in the December edition of the Journal of Cardiovascular Electrophysiology.

Lay people can effectively use defibrillators to save the lives of cardiac arrest victims

The first large-scale study to see whether trained volunteers and lay people can use defibrillators to save the lives of cardiac arrest (CA) victims has concluded that their use by lay people is safe, and if the response time can be shortened to within eight minutes there is the potential to save the lives of 15 out of 100 people who collapse suddenly with CA.

Carvedilol, a cardiovascular drug, may improve heart failure and help prevent sudden death

Research shows that Carvedilol, a cardiovascular drug, could be useful in reducing cardiac death in high risk patients with prior myocardial infarction and/or heart failure and also in reducing the incidence and/or preventing the occurrence of atrial fibrillation in a number of clinical situations.

Support for heart implants to be returned to manufacturers after death

The U.S. Food and Drug Administration (FDA) is throwing it's weight behind a policy that would mean implantable heart defibrillators would be returned to their manufacturers to be studied for possible defects after the patient dies.

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.

Study demonstrates feasibility of a revolutionary, minimally invasive approach to introducing an electrical lead to stimulate the heart

Correcting the timing of heart contractions through cardiac resynchronization therapy can be a lifesaver for people with advanced heart failure. But the procedure, as it is done today, fails in about 15 percent of patients.

Recommendations for fellowship training in pediatric cardiology

The American College of Cardiology Foundation (ACCF), the American Heart Association (AHA), and the American Academy of Pediatrics (AAP) have joined forces to develop important first-ever recommendations for fellowship training in pediatric cardiology.

Link between insomnia and obesity

A possible link between lack of sleep (insomnia) and obesity has been traced to hypocretin/orexin cells in the hypothalamus region of the brain that are easily excited and sensitive to stress, Yale School of Medicine researchers report in the April issue of Cell Metabolism.

Cryoablation may be safer alternative for stopping abnormal electrical patterns

Freezing abnormal electrical pathways in the hearts of young patients may be a safer alternative to zapping them with powerful radiofrequency probes in order to treat tachycardias and other arrhythmias, according to a new study in the April 5, 2005, issue of the Journal of the American College of Cardiology.

Bionic eyes from Stanford

Stanford physicists and eye doctors have teamed up to design a "bionic eye," of sorts. On Feb. 22 in the Journal of Neural Engineering, Daniel Palanker, Alexander Vankov and Phil Huie from the Department of Ophthalmology and the Hansen Experimental Physics Laboratory and Stephen Baccus from the Department of Neurobiology published a design of an optoelectronic retinal prosthesis system that can stimulate the retina with resolution corresponding to a visual acuity of 20/80

New form of technology to treat cardiac arrhythmias

Virginia Commonwealth University Medical Center physicians are among the first in the country to use a new form of technology to treat distant, malfunctioning areas inside the heart that cause irregular heartbeats, or cardiac arrhythmias.

Catheter ablation to treat supraventricular tachycardia (SVT) is not detrimental to patients

This data refutes previous evidence which suggested a high incidence of injury to a patient's cardiac nerves, possibly resulting in accelerated heart rates following the procedure.

31 Jan 2005

Catheter ablation safe for patients

A recent study published in Pacing and Clinical Electrophysiology (PACE) determined that the use of catheter ablation to treat supraventricular tachycardia (SVT) is not detrimental to patients.

Cardiovascular experts issue blueprint for safer X-Ray imaging

Millions of invasive cardiovascular procedures that involve the use of potentially hazardous X-rays are done in the United States each year.

Heart arrhythmias easily treated, yet few know risks

Since she was a young girl, Sandra Moore, 46, of Glen Ellyn, Ill., had episodes every few months when her heart started racing.

Scientists have developed a fast and safe method for collecting heart stem cells from small amounts of biopsied heart tissue

In human and animal studies, scientists at Johns Hopkins have developed a fast and safe method for collecting heart stem cells from remarkably small amounts of biopsied heart tissue (15 mg or less), and growing the cells in the lab to get more.
