Pulmonary valve insufficiency

This study looked at the SAPIEN XT heart valve, which is placed through a thin tube (catheter) to fix a failed valve in the heart's right ventricle. Researchers wanted to confirm it is safe and works well. They enrolled 57 people with a narrowed or leaky heart valve conduit. The …

This study tested a new valve called the Pulsta® Transcatheter Pulmonary Valve in 15 people with congenital heart disease and a faulty pulmonary valve. The valve is implanted through a catheter, avoiding open-heart surgery. Researchers checked if the valve improved blood flow and…

This study tests whether a new device that records chest vibrations from a distance can detect heart and lung diseases. Researchers will compare the vibration patterns of people with known cardiac or pulmonary conditions to those of healthy volunteers. If the technique works, it …

This trial tests whether a stellate ganglion block—an injection near a nerve cluster in the neck—can help people recover faster after heart valve replacement surgery. Half of the 62 participants receive the block with a numbing medication, while the other half gets a placebo. Res…

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 tested whether using a contrast dye during 3D ultrasound can accurately measure the size and function of the right heart chamber in people who had surgery for congenital heart disease. 25 participants received an injection of Lumason (an ultrasound contrast agent) and …

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…
