A stenosis is an abnormal narrowing in a blood vessel or other tubular organ or structure.
Patients of the Mainz University Medical Center with heart valve disease have recently been able to benefit from a new treatment option for a narrowed aortic valve.
For years, spine surgeons have debated the best methods for treating scoliosis in adults. Spinal curvature often results in more back pain, leg pain and other symptoms for adults than teens because adults also can have degeneration in the discs between vertebrae, and spinal stenosis -- a narrowing of the opening for the spinal nerves.
Why do some patients recover quickly after surgery, while others don't? That is an important question when treating older frail patients suffering from aortic stenosis. Lead author Dae Hyun Kim, M.D., M.P.H., Sc.D., and principle investigator Director Lewis A. Lipsitz in the Marcus Institute for Aging Research at Hebrew SeniorLife explore this question in a paper published today in the Journal of the American Medical Association Internal Medicine.
Affecting an estimated one in eight people older than 75, aortic valve stenosis - a narrowing of the heart's main artery - makes the heart work harder to supply the body with blood, potentially limiting patient's activity levels an quality of life. Ultimately, aortic stenosis can lead to stroke, arrhythmia, heart failure and death.
Engineers at The University of Texas at Austin have developed a new noninvasive technique for simulating repairs to the heart's mitral valve with levels of accuracy reliable enough for use in a clinical setting.
Founded in 2008, the Biodonostia Health Research Institute was the first institute for medical research in the Basque region of Spain. Facing difficult surgical challenges every day, it recently partnered with Tknika, a Research and Applied Innovation Centre for Vocational Education and Training in the Basque region, and Tecnun, a specialist division of Universidad de Navarra, to enable surgeons to harness the latest 3D printing technology as a tool to aid surgical preparedness.
Imec have developed a prototype medical device based on silicon photonics for the screening of arterial stiffness and cardiovascular diseases.
Thubrikar Aortic Valve, Inc., a privately held medical device company, today announced the first human implant of the Optimum TAV using their transcatheter aortic valve implantation system.
RTI Surgical, Inc., a global surgical implant company, and Paradigm Spine, LLC, a leader in motion preservation and non-fusion spinal implant technology, today announced that they have entered into a definitive agreement whereby RTI will acquire all outstanding equity interest of Paradigm Spine in a cash and stock transaction valued at up to $300 million, consisting of $150 million at closing plus potential future milestone payments.
Individual cells within the same heart cope differently with high blood pressure, according to a study in human cells and mice by a team of cardiologists and computational biologists at the University of Tokyo.
Most people who need open heart surgery to repair damaged heart valves are aged 65 or older. The American Heart Association estimates that nearly 8 million people have had heart surgeries.
Loyola Medicine neurologist Michael Schneck, MD, is a 2018 recipient of a Presidential Citation from the Neurocritical Care Society in recognition of his extraordinary efforts on behalf of the society.
In the largest multi-institutional study to date, led by researchers from Penn Medicine, the team found that among patients who underwent a transcatheter aortic valve replacement, a high number experienced severe and moderate cases of prosthesis-patient mismatch--meaning the implanted heart valve is too small for the patient which can lead to inadequate blood flow.
Resistant hypertension affects 12 percent to15 percent of patients treated for high blood pressure according to a new scientific statement from the American Heart Association.
In the current issue of Cardiovascular Innovations and Applications (Volume3, Number 2, 2018, pp. 237-250(14); DOI: https://doi.org/10.15212/CVIA.2017.0040 Randy R. Jeffrey, Robert F. Hamburger, Janelle Gooden-Ebanks and John W. Petersen from the Division of Cardiovascular Medicine, Department of Medicine, University of Florida, Gainesville, FL, USA consider impaired longitudinal strain as a common deficit in various cardiac diseases.
Royal Philips, a global leader in health technology, today announced that the European Society of Cardiology has incorporated instantaneous wave-free ratio into its updated revascularization guidelines.
Results of a clinical trial using transcatheter aortic valve replacement provided a "strong signal" that it is safe for patients with low surgical risk, potentially helping to open the way for broader use of the minimally invasive procedure, also known as TAVR.
Unnecessary heart procedures can be avoided with a non-invasive test, according to late breaking research presented at ESC Congress 2018 and published in Journal of the American College of Cardiology.
The initial findings of a study on spontaneous coronary artery dissection, a major cause of heart attacks in women, are reported today in a late breaking science session at ESC Congress 2018.
A weight loss drug does not increase cardiovascular events, according to late breaking results from the CAMELLIA-TIMI 61 trial presented today in a Hot Line Session at ESC Congress and published in the New England Journal of Medicine.
