Mitral valve stenosis

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 whether a left stellate ganglion block, given before mitral valve replacement, could protect the heart muscle. 62 adults undergoing elective on-pump mitral valve replacement received either a saline placebo or bupivacaine nerve block. Researchers checked for mic…

This study looked at two types of exercise training—moderate-intensity interval training and continuous training—in 56 adults aged 40-60 who had mitral valve replacement surgery 4-8 weeks earlier. Over 12 weeks, researchers measured walking ability, lung function, heart efficienc…

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 study tests a small, wearable ECG patch that uses artificial intelligence to monitor heart rhythms in patients recovering from cardiac surgery. Participants wear the patch for up to a week after leaving the intensive care unit. The goal is to see if the device can reliably t…

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 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…

This study tested a computer program called naevia medical that helps doctors decide the best treatment for heart valve disease. Researchers looked at 106 past patient cases to see if the tool gave better recommendations than usual care. The goal was to see if the tool could redu…
