A stenosis is an abnormal narrowing in a blood vessel or other tubular organ or structure.
A collaboration between stroke neurologists at the Medical University of South Carolina and bioengineers at the University of Massachusetts has led to the creation of a realistic, 3D-printed phantom of a stenotic intracranial artery that is being used to standardize protocols for high-resolution MRI, also known as vessel-wall MRI, at a network of U.S. and Chinese institutions, according to an article published online March 9, 2017 by the Journal of NeuroInterventional Surgery.
UCLA scientists have found that conscious sedation -; a type of anesthesia in which patients remain awake but are sleepy and pain-free -; is a safe and viable option to general anesthesia for people undergoing a minimally invasive heart procedure called transcatheter aortic valve replacement.
One of the most common, and most serious, heart valve diseases is aortic stenosis. Left untreated, aortic stenosis gradually diminishes quality of life and leads to heart failure and death.
Low-level laser therapy has been shown by recent studies to be a non-invasive and effective alternative for treating neuropathic pain, a chronic condition caused by nerve damage, spinal cord injury or diseases such as diabetes.
A new tool for assessing the narrowing of the heart's arteries was found to be as effective as current methods and less painful for patients.
People with spinal deformity also requiring a total hip replacement are at greater risk for dislocation or follow-up revision surgery, suggesting that these higher-risk patients may benefit from a more personalized approach to their surgeries to reduce the risk of poorer outcomes.
A ground-breaking project at Birmingham Children’s Hospital using wireless technology to predict deterioration in seriously ill children has recruited it’s 1,000th patient.
Well-informed patients who decide with their orthopaedic surgeon what treatment is best for them have better outcomes and higher patient satisfaction rates, according to new study presented today at the 2017 Annual Meeting of the American Academy of Orthopaedic Surgeons.
An approved international test to check whether people need open heart surgery could be sending twice as many people under the knife unnecessarily, at a cost of nearly £75m, research by the University of Leicester has suggested.
A team of researchers from the Research Institute of the McGill University Health Center found that elevations in a unusual form of cholesterol, called Lipoprotein(a) or Lp(a), as responsible for 1 in 14 heart attacks and 1 in 7 cases of aortic valve disease.
Many patients live with low back pain that radiates to the buttock, groin, thigh, and even knees. The challenge for patients, and often their doctors, is determining the origin of the pain -- the hip, the spine, or both.
Elderly patients with aortic stenosis (AS) and medium surgical risk experienced better than expected results after undergoing traditional surgical aortic valve replacement, according to research presented at the 53rd Annual Meeting of The Society of Thoracic Surgeons.
As the valves in a heart stretch with each beat, their cells take in life-giving oxygen. But if the supply is cut off, aortic and mitral valves use different strategies to compensate, according to Rice University scientists.
OrbusNeich has announced the launch of its latest generation Dual Therapy Stent (DTS), the COMBO Plus.
For patients with degenerative spinal disease, surgery is more effective in reducing pain that interferes with sexual activity, compared to nonsurgical treatment, reports a study in the November 15 issue of Spine, published by Wolters Kluwer.
EuroEcho-Imaging 2016 brings advanced techniques to the bedside with international experts set to discuss the use of holograms and 3D printing to guide interventions.
UK charity Heart Valve Voice today launches its report, ‘Towards a Heart Healthy Future: a 2020 Vision for Heart Valve Disease’ at a parliamentary event attended by MPs across the country.
The 28th annual Transcatheter Cardiovascular Therapeutics (TCT), the annual scientific symposium of the Cardiovascular Research Foundation featured a number of first report investigations on novel stents that could become the next generation of bioresorbable stents in patients.
Researchers at the National Institutes of Health have developed a new, less invasive way to perform transcatheter aortic valve replacement (TAVR), a procedure widely used to treat aortic valve stenosis, a lethal heart condition.
During their lifetime, as many as eight out of ten people experience back pain that lasts more than three days. However, for a vast majority of these people, the pain goes away with simple treatment.
