People with Common Heart Defect Also More Likely to Have Brain Aneurysms

04.05.2010
A new study shows that people with a common heart defect may also be more likely to have brain aneurysms. The study is published in the May 4, 2010, print issue of Neurology®, the medical journal of the American Academy of Neurology.

Up to two percent of the population is born with the heart defect called a bicuspid aortic valve (BAV). The aortic valve allows blood to flow from the heart to the aorta. It normally has three flaps that open and close to regulate blood flow. In people with a bicuspid aortic valve, the valve does not develop fully during gestation and there are two flaps instead of three.

Some people with BAV never have any problems, but many develop narrowing or leakage of the aortic valve, especially as adults.

Recent research has shown that the artery problems with BAV may also occur in the brain, and that BAV may be a connective tissue disorder. Brain aneurysms are a weakening in a brain artery that causes a bulge in the artery.

“Since brain aneurysms are a treatable problem that can lead to death and disability if they rupture, we wanted to find out how common they are in people with BAV,” said study author Wouter Schievink, MD, Director of Microvascular Neurosurgery at Cedars-Sinai Medical Center in Los Angeles, Calif.

For the study, 61 people with BAV were screened for brain aneurysms, along with 291 people who did not have BAV but were undergoing scans for a suspected stroke or brain tumor during the same time period.

Six of the 61 people with BAV had brain aneurysms, or 9.8 percent, compared to three of the 291 people who did not have BAV, or 1.1 percent. Studies have shown that 0.5 to two percent of the general adult population has brain aneurysms.

“While more research needs to be done to confirm these results, these findings show a significant increased risk of brain aneurysms in people with bicuspid aortic valves,” Schievink said.

Schievink said the heart defect has been shown to cluster in families, and screening is generally recommended for close family members of people diagnosed with bicuspid aortic valves.

The American Academy of Neurology, an association of more than 22,000 neurologists and neuroscience professionals, is dedicated to promoting the highest quality patient-centered neurologic care. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as multiple sclerosis, restless legs syndrome, Alzheimer’s disease, narcolepsy and stroke.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
