Less Invasive, Implantable Defibrillators Pose Less Risks to Heart Patients

Comstock/Thinkstock(ROTTERDAM, Netherlands) -- Implantable heart defibrillators save lives, but there are risks associated with them. A new type of defibrillator that's less invasive, however, may help reduce some of those risks without compromising efficiency.

Implantable Cardioverter Defibrillators, or ICDs, work by detecting and correcting abnormal heart rhythms that can lead to heart attack or death. The sensor part of the defibrillator is placed directly in the heart.  Serious problems could develop if it breaks, gets dislodged or causes an infection.

But the new ICD, or S-ICD, is implanted just under the skin instead of the heart.

According to a report presented at an international meeting of the Heart Rhythm Society, the new device performed with 100-percent accuracy.

Researchers in the Netherlands studied 98 patients over a nine-month period.  The ICD under the skin never failed to detect and correct abnormal heart rhythms during the trial.

The new ICD is already in use in Europe, but not in the United States. If approved by the FDA, the device could have a profound impact on heart patients, especially in cases where several members of a single family suffer congenital heart conditions.

Study Finds Heart Failure Treatment More Effective For Women 

Image Courtesy - Getty Images(CHICAGO) -- A new study says that a therapy to prevent heart failure is twice as effective in women as it is in men. When women were treated with a device that serves as both a pacemaker and a defibrillator, they had a 70-percent reduction in heart failure, compared to just half that rate in men, the study found.

This research builds off of a similar study done in 2009 that showed patients fared better with a combination device, rather than just with a defibrillator alone. Researchers say this data is significant because it is the first study that shows a treatment that is clearly more effective in women than in men.

The reason the combination device proved to be so effective, the study said, is because it not only regulates the heart's pace, but can monitor if there is a slowdown in the heartbeat, and send an electrical pulse to make it pick up the pace. The research centers around what is known as resynchronization therapy, a process that forces both sides of the heart to beat in unison. Women generally suffer more from this problem, researchers said, which explained why their bodies responded better to the device.

Included in the research were 453 female participants and 1,367 male subjects.

The study, entitled "Cardiac Resynchronization Therapy Is More Effective in Women Than in Men:
The Multicenter Automatic Defibrillator Implantation Trial With Cardiac Resynchronization Therapy Trial," was published in the Journal of the American College of Cardiology.

FDA Seeks Tougher Oversight for Defibrillators

Photo Courtesy - Getty Images(ROCKVILLE, Md.) – The Food and Drug Administration has asked for greater standards for external defibrillators as issues with the technology have led to several recalls, according to HealthDay News.

The FDA Tuesday asked a panel of advisors for stricter oversight on the devices, which are used to jumpstart a patient’s heart in an emergency, because manufacturers have failed to fix problems that led to the recalls.

In the past five years, the FDA says there have been 68 recalls of the device, as well as 23,591 reports of malfunction.

Defibrillators Can Be Recycled after Resterilizaton, Researchers Say

Photo Courtesy - Getty Images(CHICAGO) -- Researchers have recently discovered that implantable cardioverter defibrillators can be removed from patients no longer needing them and reimplanted into other patients, provided that they have sufficient battery life, according to MedPage Today.

A recent test resulted in a 35-percent success rate in the procedure, reported Dr. Behzad Pavri of Thomas Jefferson University in Philadelphia at an American Heart Association meeting.

To date, infectious complications from the procedure, which requires that patient data be erased from the devices before sterilization and repackaging, have not been reported.
