(Press-News.org) Patients with atrial fibrillation (A-fib) who cannot take blood thinners now have an alternative to reduce their risk of stroke, which is five times more common in people with the rhythm disorder. The non-surgical procedure works by tying off the left atrial appendage (LAA), the source of most blood clots leading to stroke in patients with A-fib. Northwestern Medicine® heart rhythm specialists from the Bluhm Cardiovascular Institute were the first to perform this procedure in Illinois.
"Traditionally, surgery was required to close off the LAA. Now we have the ability to safely and permanently close it using a minimally invasive, non-surgical approach," said Brad Knight, MD, medical director of the Center for Heart Rhythm Disorders at the Bluhm Cardiovascular Institute. "This is an innovative method that has the potential to revolutionize the field of stroke prevention in patients with cardiac rhythm disorders."
The procedure, known as LAA occlusion, is performed using the FDA-approved LARIAT® Suture Delivery Device. Doctors access the LAA by inserting a catheter, or thin tube, under the rib cage into the sac around the heart through which the suture to tie off the LAA is delivered. Another catheter is advanced through a blood vessel in the groin up into the heart, and positioned inside the LAA to help guide the suture over the LAA. The outpatient procedure eliminates the number one source of heart related stroke, while avoiding the potentially serious side effects associated with blood thinners.
"We are happy to be able to give our patients another option. Non-surgical procedures mean less discomfort and a shorter recovery time," said Albert Lin, MD, associate medical director of Cardiac Electrophysiology at the Bluhm Cardiovascular Institute. "Drug therapies have historically been the first line of defense for patients with A-fib, but they are not tolerated by all patients and can pose serious side effects for some. Now, we have the ability to safely and permanently close the LAA without the need for major surgery and potentially protect against the risk of stroke."
A-fib is a condition where a rapid and irregular heart beat can cause serious complications, including stroke, heart failure and early death. Some people with A-fib have no symptoms and are unaware of their condition until it's discovered during a physical examination. Those who do have A-fib symptoms may experience palpitations or sensations of a racing, irregular heartbeat, shortness of breath, chest pain or lightheadedness.
A-fib related deaths have increased over the past two decades and now account for one-quarter of all strokes in the elderly.
"There has recently been a renaissance in the treatment of atrial fibrillation. This latest technological advance represents yet another novel approach to treat atrial fibrillation," said Clyde Yancy, MD, chief of the Division of Cardiology and associate director of the Bluhm Cardiovascular Institute.
"This is a great option for patients with A-fib who are at high risk for stroke but cannot safely take blood thinners," said Knight. "The procedure is non-invasive and the recovery time is short, so patients are able to return to their daily activities quickly."

GAINESVILLE, Fla. — "Hot Jupiter-type" planets are most likely to be alone in their systems, according to research by a University of Florida astronomer and others, made public today.
"Hot Jupiters" are giant planets beyond our solar system, roughly the size of Jupiter but orbiting close to their parent stars and thus much hotter than the Earth or Jupiter, said UF professor Eric Ford. They have very short orbital periods, completing a turn around their stars in fewer than 10 days. This study, published in the journal Proceedings of the National Academy of Sciences, provides ...
To calculate physicians' fees under Medicare – which in turn influence some state and private payers' decisions on how they will pay doctors -- the Centers for Medicare and Medicaid Services (CMS) relies on the recommendations of an American Medical Association advisory panel. A study led by Miriam Laugesen, PhD at Columbia University's Mailman School of Public Health, found that the Medicare and Medicaid agency closely followed the committee's recommendations on the fees physicians are paid, which are based on an assessment of time and effort associated with various physicians' ...
Changes in the speed that ice travels in more than 200 outlet glaciers indicates that Greenland's contribution to rising sea level in the 21st century could be significantly less than the upper limits some scientists thought possible.
The finding comes from a paper funded by the National Science Foundation (NSF) and NASA and published in today's journal Science.
While the study indicates that a melting Greenland's contributions to rising sea levels could be less than expected, researchers concede that more work needs to be done before any definitive trend can be identified.

DURHAM, N.C. -- Advanced high-speed gene-sequencing has been used in the clinical setting to find diagnoses for seven children out of a dozen who were experiencing developmental delays and congenital abnormalities for mysterious reasons.
"I thought if we could obtain even a couple of relatively secure diagnoses out of the 12 patients, that would prove the value of deploying sequencing approaches systematically in patients with unknown but apparently genetic conditions," said David Goldstein, Ph.D., director of the Duke Center for Human Genome Variation and professor ...
San Diego, CA, May 8, 2012 – As populations move even further away from urban centers, more people spend longer hours behind the wheel on their way to and from work. While sedentary behavior is known to have adverse effects on cardiovascular and metabolic health, the impact of long commutes by automobile are less understood. A new study has found that greater commuting distances are associated with decreased cardiorespiratory fitness (CRF), increased weight, and other indicators of metabolic risk. The results are published in the June issue of American Journal of Preventive ...
