Congenital aortic valve insufficiency

This study tested whether a new way of processing tissue for Edwards heart valves is safe and works well. 777 adults who needed a new aortic or mitral valve took part. Researchers checked for valve problems like wear or calcification over about a year, and will follow patients fo…

This study tested a special heart-protection method given during heart surgery to see if it could reduce damage to the heart muscle. 210 adults having aortic valve surgery took part. Researchers measured a protein called troponin I in the blood for 72 hours after surgery to check…

This study tested whether virtual reality relaxation or binaural beat stimulation can improve sleep and reduce discomfort in 140 adults who had mechanical heart valve replacement. Many patients struggle with sleep due to the sound of the new valve. Participants were randomly assi…

This completed study looked at 172 patients who received either a new-generation biological aortic valve or a traditional one during heart surgery. Researchers tracked survival and valve function over five years to see how the newer valves compare. The goal is to provide real-wor…

This study looked at 1,811 patients aged 60-70 who had heart valve replacement surgery. Researchers compared different types of artificial valves to see if the valve type was linked to developing depression, anxiety, or sleep disorders later. The goal was to understand if the cho…

This completed study used artificial intelligence to analyze electrocardiograms (ECGs) and chest X-rays from over 116,000 adults. The goal was to see if combining these routine tests could predict which patients would develop moderate or severe heart valve regurgitation. The rese…

This study looked at 80 adults having heart valve or aortic surgery to find out how long a special heart protection solution (Del Nido cardioplegia) keeps the heart safe during surgery. Researchers took blood samples at set times to see when heart injury began. The goal was to le…

This study looked back at 198 patients who had a sutureless aortic valve replacement to see how often they developed heart rhythm problems. These newer valves are faster to implant but have a metal frame that might affect the heart's electrical system. The goal was to better unde…

This study collected information from multiple hospitals on the Cor-Knot® device, which automatically ties knots during heart valve surgery. The goal was to see how safe and effective it is. Over 550 adults having planned valve surgery took part. The main focus was on whether lea…
