AORTIC VALVE STENOSIS

This study tested whether implanting a new aortic valve (TAVI) without first using a balloon to open the narrowed valve is safer and as effective as the standard procedure with balloon predilatation. 250 adults with severe aortic stenosis who were at high risk for open-heart surg…

This study tested a device designed to catch and remove debris that can break loose during transcatheter aortic valve replacement (TAVR), a procedure to replace a narrowed heart valve. The device uses two filters placed in arteries leading to the brain. The trial involved 260 peo…

This study followed 650 low-risk patients with severe aortic valve narrowing who received a less invasive valve replacement called TAVI. Researchers tracked deaths, strokes, and return hospital visits for heart problems. The goal was to see how well TAVI works in everyday practic…

This study tested whether empagliflozin (Jardiance), a diabetes drug, can help the heart recover after aortic valve replacement. 206 patients took either the drug or a placebo for six months. The goal was to see if the drug reduces heart muscle thickness and improves symptoms.

This study looked at whether giving a drug called protamine to all patients after a minimally invasive heart valve replacement (TAVI) reduces bleeding complications compared to giving it only when needed. The trial involved 1000 adults with aortic valve stenosis. The goal was to …

This study looked at whether using half the usual dose of heparin during heart surgery (bypass or valve replacement) could reduce bleeding afterward. Heparin is a blood thinner used to prevent clots during surgery, but it can increase bleeding. The study involved 238 adults and c…

This study tested two new heart valves (Portico and Navitor) in 30 Indian patients with severe aortic stenosis, a condition where the heart's main valve narrows. The goal was to see if the valves are safe and work well. Researchers tracked complications and heart function for up …

This study tested whether the anesthetic sevoflurane protects the heart better than propofol during aortic valve replacement surgery. 82 patients were randomly assigned to receive either sevoflurane or propofol during and after surgery. The researchers measured troponin levels, a…

This study tested a new heart valve called Evolut PRO in 638 people with severe aortic stenosis who were at high risk for open-heart surgery. The valve was implanted using a thin tube through an artery, avoiding major surgery. Results showed that only 3.3% of patients died within…

This study tested whether giving the pain medicine sufentanil as a continuous drip during heart surgery helps patients wake up and leave the ICU sooner compared to giving it as single shots. 65 adults having planned heart surgery took part. The goal was to see if the drip method …

This study tested whether an ultrasound-guided belly muscle nerve block (TAP block) can reduce pain and movement during a minimally invasive heart valve replacement (TAVI). Fifty adults having elective TAVI received either the block plus sedation or sedation alone. The goal was t…

This study tested a new sedative called ciprofol against the standard drug propofol for general anesthesia in 124 older adults undergoing transcatheter aortic valve replacement (TAVR). The goal was to see if ciprofol causes fewer episodes of low blood pressure after anesthesia. R…

This study tested whether a special ultrasound-guided nerve block (PENG block) can reduce pain and the need for extra painkillers in 40 adults undergoing transcatheter aortic valve implantation (TAVI) for aortic stenosis. The block targets nerves around the hip to provide pain re…

This study tested whether using lighter sedation (monitored anesthesia care) instead of general anesthesia with a breathing tube could help people recover faster after a minimally invasive heart valve replacement called TAVR. The trial included 170 adults getting TAVR through a l…

This study tested a new way to predict dangerous heart rhythm problems after a common heart valve procedure called TAVR. Researchers combined ECG results with CT scan measurements and implant depth to see if they could safely identify low-risk patients. The study looked back at 2…

This study compared two common sedation drugs, propofol and dexmedetomidine, in 65 older adults undergoing a less invasive heart valve replacement called TAVR. The goal was to see which drug leads to better kidney function, less confusion, and fewer complications after the proced…

This study looked at 22 people with severe aortic stenosis who were scheduled for valve replacement. Before surgery, they had an ultrasound of the heart, and during surgery a tiny sample of heart muscle was taken to check for scarring (fibrosis). The goal was to see if ultrasound…

This study looked at 70 adults having open heart surgery (aortic valve or bypass). It compared a newer, smaller heart-lung machine to the standard one. The goal was to see which method better protects the body's tissues and the brain during surgery. Results will help doctors choo…

This study looked at 60 heart surgery patients to see how two different bypass machines affect blood flow in tiny vessels under the tongue. One method was minimally invasive, the other was the standard approach. The goal was to find out which technique keeps small blood vessels w…

This study looked at 86 people with severe aortic valve stenosis who had valve replacement surgery. Researchers used special MRI scans to measure scarring in the heart muscle before and one year after surgery. The goal was to see if the scarring improves and whether MRI could hel…

This study tested whether automated alerts in electronic health records help doctors identify and treat patients with severe aortic stenosis or mitral regurgitation. Over 2,100 patients were included, and some doctors received alerts while others did not. The goal was to see if a…

This study tested a program to help people with severe aortic stenosis get a TAVI heart valve procedure faster. The program included a website and booklet for patients, plus better coordination among hospital teams. Researchers measured whether more patients could be treated with…

This study looked at whether the time of day a person has heart surgery changes how their heart muscle tolerates the stress of the procedure. Researchers took small tissue samples from the hearts of 88 patients having planned heart surgery, either in the morning or afternoon. The…

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…

This study followed 77 patients under 60 who had a mechanical aortic valve replacement to see if a mismatch between the valve size and the patient's body affects heart recovery and exercise ability. Participants did exercise tests and heart ultrasounds years after surgery. The go…

This study tested whether two advanced heart ultrasound measures (LACI and LV speckle tracking) can better predict complications like hospital readmission, heart attack, or stroke after TAVI valve replacement. Researchers studied 100 patients with severe aortic stenosis. The goal…

This study used a special ultrasound technique called elastography to measure heart muscle stiffness during planned aortic valve replacement surgery. Researchers compared stiffness in patients with aortic stenosis to those having bypass surgery. The goal was to see if aortic sten…
