Atrial fibrillation

This study tested a device called the Amplatzer Amulet, which is implanted to close a part of the heart and reduce stroke risk in people with non-valvular atrial fibrillation who cannot take blood thinners. The study enrolled 50 participants in China and tracked safety and effect…

This study aimed to see if combining surgical and catheter ablation (hybrid therapy) works better than standard catheter ablation alone for people with persistent atrial fibrillation. The trial was terminated after enrolling only 7 participants, so no meaningful conclusions can b…

This study compared two types of heart ablation for people with paroxysmal atrial fibrillation (AFib). One group received standard pulmonary vein isolation, while the other also had the back wall of the left atrium isolated. Both used a newer technique called pulsed-field ablatio…

This study looked at whether a procedure called renal denervation could help people with recurrent atrial fibrillation (an irregular heartbeat) that keeps coming back even after standard treatment. The procedure uses energy to calm certain nerves near the kidneys. Only 6 people t…

This study tested a drug called CardiolRx in 90 hospitalized COVID-19 patients who also had heart disease or risk factors like diabetes or high blood pressure. The goal was to see if the drug could lower the chance of death, needing intensive care, or having heart problems. The t…

This study tested a medical device that freezes small areas of heart tissue to treat atrial fibrillation (AFib) and related irregular heartbeats. The goal was to see if the procedure safely stops abnormal rhythms for at least 12 months. The study enrolled 91 people, but was termi…

This trial tested whether giving two quick electrical shocks instead of one could better restore a normal heart rhythm in people with atrial fibrillation. It focused on patients with factors that make standard shock treatment less likely to work, such as obesity or lung disease. …

This study looked at how well the DiamondTemp ablation system controls atrial fibrillation (a type of irregular heartbeat) over three years. It included 84 adults with paroxysmal AF who had not responded to medication. The study was terminated early, so the full results are not a…

This pilot study compared a heart ablation procedure (pulmonary vein isolation) to standard medications for managing atrial fibrillation in people with heart failure with preserved ejection fraction. Only 13 participants were enrolled before the study was terminated early. The ma…

This study tested whether checking blood clotting levels every week with a small finger-prick device is better than the usual monthly lab test for elderly nursing home residents on blood thinners. The goal was to see which method keeps patients in the safe therapeutic range longe…

This study tested whether a single high dose (2000 mg) of the heart medication amiodarone, taken by mouth, could safely and quickly restore normal heart rhythm in people with acute atrial fibrillation. The trial planned to include both hospital and outpatient settings, but was te…

This study tested a device called Efferon LPS that filters blood during heart surgery when a heart-lung machine is used. The goal was to see if it could prevent multiple organ failure, especially kidney damage. Only 14 people took part before the study was stopped, so the results…

This study looked at whether the drug dronedarone could prevent atrial fibrillation (AFib) from coming back after a heart ablation procedure. About 22 adults with AFib who had ablation were randomly given either dronedarone or a placebo. The goal was to see if the drug reduced ir…

This small pilot study tested whether a special oral appliance (like a mouthguard) could reduce episodes of atrial fibrillation, a common heart rhythm problem. Only 3 people participated, and the study was ended early. The device is already used for snoring and sleep apnea, but i…

This study looked at whether using a positive airway pressure (PAP) machine at night can reduce the return of atrial fibrillation (an irregular heartbeat) in people who also have obstructive sleep apnea. About 129 participants with both conditions were assigned to receive either …

This study looked at using the WATCHMAN FLX device, a small plug placed in the heart, to prevent strokes in people with atrial fibrillation (an irregular heartbeat) who also had serious gastrointestinal (GI) bleeding. The device is meant to close off a part of the heart where clo…

This study compared two types of nerve blocks (serratus anterior plane block and erector spinae plane block) using the same dose of ropivacaine to manage pain after hybrid arrhythmia ablation surgery. It enrolled 28 adults aged 18-80. The trial was terminated early, so findings a…

This study looked at whether letting patients manage their own recovery precautions after heart surgery leads to a better quality of life compared to following standard sternal precautions. Ten adults who had heart surgery were followed for up to a year. Researchers checked pain,…

This study looked at how two common pain relievers—celecoxib (a Coxib) and naproxen (an NSAID)—affect blood clotting in people with rheumatoid arthritis who also have heart disease or are at high risk for it. All participants took low-dose aspirin daily. The goal was to see if on…

This study aimed to understand why some people with genetic early-onset atrial fibrillation (AF) are at risk for a dangerous heart rhythm called ventricular tachycardia (VT). Researchers used special heart mapping during a standard AF ablation procedure in 32 adults. The goal was…

This study looked at a common heart rhythm problem called atrial fibrillation (AF). The goal was to find better ways to predict which patients would benefit from a procedure called ablation, which creates scar tissue in the heart to stop abnormal rhythms. Researchers planned to u…

This study looked at how Medtronic heart devices detect and manage atrial fibrillation (AF) in Indian patients. It tracked whether the condition became persistent over time. The study enrolled 79 people over 55 with heart devices. It was terminated early, so results are limited.

This study looked at whether using ultrasound to guide vein puncture reduces complications like bleeding or false aneurysms in people undergoing ablation for atrial fibrillation. Over 1,000 adults scheduled for the procedure were enrolled. The study was terminated early, so resul…
