3D Model of the heart by Dr. Matthew Bramlet. Credit: NIH 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 (TAVR), a high number experienced severe and moderate cases of prosthesis-patient mismatch (PPM)—meaning the implanted heart valve is […]Continue Reading ...
Most people who need open heart surgery to repair damaged heart valves are aged 65 or older. The American Heart Association (AHA) estimates that nearly 8 million people have had heart surgeries. However, we don’t fully understand the effects of heart surgery on an older adult’s cognition (the ability to remember, think, and make decisions). […]Continue Reading ...
Animal-derived heart valves are preferred to mechanical ones for valve-replacement heart surgery because they are more biocompatible and do not require a life-changing regime of anticoagulant drugs. However, in young patients, animal-derived valves only have a lifespan of around five to ten years as the result of premature dysfunction. This means valves derived from cattle […]Continue Reading ...
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 (TAVR), a high number experienced severe and moderate cases of prosthesis-patient mismatch (PPM)–meaning the implanted heart valve is too small for the patient which can lead to inadequate blood […]Continue Reading ...
August 14, 2018 Current treatment guidelines say patients who undergo minimally invasive aortic heart valve replacements should receive two antiplatelet drugs to reduce the risk of dangerous blood clots. A new Loyola Medicine study has found that giving patients a single antiplatelet drug may work as well as giving two drugs, with significantly lower risks […]Continue Reading ...
July 4, 2018 A Smidt Heart Institute patient is the first in the country to receive a new device to fix a leaky heart valve. The patient, Sheldon Kardener, MD, received the device July 1 during a 30-minute minimally invasive procedure in Cedars-Sinai’s Cardiac Catheterization Lab as a treatment for mitral valve regurgitation. The procedure […]Continue Reading ...
April 19, 2018 In the current issue of Cardiovascular Innovations and Applications (Volume 2, Number 4, 2018, pp 431-434(4); DOI: https://doi.org/10.15212/CVIA.2017.0034, researcher Blase A. Carabello, from East Carolina University, Greenville, NC, USA presents a case study of an asymptomatic patient with severe mitral regurgitation. In primary mitral regurgitation there are anatomic abnormalities of the mitral […]Continue Reading ...
Infective endocarditis is “not uncommon” after surgical mitral and aortic valve replacement, as determined by a Danish registry analysis. The cumulative risk of infective endocarditis over 10 years was 5.2% after both mitral and aortic valve replacement, according to Lauge Østergaard, MB, of Rigshospitalet in Copenhagen, and colleagues. Their study took records from the Danish […]Continue Reading ...
A latest study has shown that sudden cardiac death could be linked to a very common heart condition – mitral valve prolapse. Sudden cardiac death occurs when the heart suddenly stops beating. This connection is a significant breakthrough say experts. The new study titled, “Mitral valve prolapse and sudden cardiac death: a systematic review and […]Continue Reading ...
A University of Adelaide-led team of researchers has found a link between sudden cardiac death (when the heart suddenly stops beating) and a common heart condition known as mitral valve prolapse that affects around 12 in every 1000 people worldwide. In a paper, published in Heart, researchers aanalyzed more than 7600 studies and found that […]Continue Reading ...
August 17, 2018 When Medicare in 2011 agreed to pay for a revolutionary procedure to replace leaky heart valves by snaking a synthetic replacement up through blood vessels, the goal was to offer relief to the tens of thousands of patients too frail to endure open-heart surgery, the gold standard. To help ensure good results, […]Continue Reading ...
July 19, 2018 The number of patients undergoing mitral valve operations are at an all-time high, and new research posted online today in The Annals of Thoracic Surgery suggests that many patients don’t undergo surgical intervention until it’s too late to completely reverse damage caused by mitral valve disease. “This study shows that a significant […]Continue Reading ...
April 27, 2018 A new study finds patients who stay in the hospital for more than 72 hours when undergoing trans-femoral transcatheter aortic valve replacement (TF-TAVR) procedure may be associated with negative short and long-term outcomes. The authors, for the first time, report a significant decline in the rates of delayed discharge; and identified independent […]Continue Reading ...
April 18, 2018 Calcific aortic valve disease (CAVD) – a disease that leaves the aortic valve stiff and calcified, preventing blood flow from the heart into the aorta – affects one quarter of the U.S. population aged 65 and over. There is no pharmacological treatment for CAVD. Without an invasive valve replacement surgery, most patients […]Continue Reading ...
March 7, 2018 The U.S. Food and Drug Administration today expanded the approval of a heart valve to include a size small enough to be used in newborn pediatric patients to treat heart defects. Specifically, the agency approved the Masters Series Mechanical Heart Valve with Hemodynamic Plus (HP) Sewing Cuff to include the 15-mm valve […]Continue Reading ...
