Atrioventricular dissociation

This study tests whether pregnant women at high risk for fetal heart block can use a home monitor to catch early signs of the condition. If detected, they receive steroids and IVIG to try to reverse the block before it becomes permanent. The goal is to prevent stillbirth and the …

This study follows 2000 people who have or will get the OmniaSecure defibrillation lead, a wire that helps control dangerous heart rhythms. Researchers will track how often the lead causes problems over 5 years. The goal is to make sure the lead is safe and works as expected in e…

This study compares a newer pacemaker method, left bundle branch area pacing (LBBAP), to the standard right ventricular pacing in 200 patients with heart block and normal heart function. The goal is to see if LBBAP better preserves the heart's pumping ability and reduces complica…

This study compares a newer pacing method called left bundle branch area pacing (LBBAP) with standard right ventricular pacing in 100 adults who need a pacemaker but have normal heart function. The goal is to see if LBBAP better prevents the decline in heart pumping ability that …

This study is tracking 100 adults who receive an EluPro antibiotic-eluting envelope during implantation of a heart device (like a pacemaker). The envelope slowly releases antibiotics to prevent infection. Researchers are monitoring complication rates in real-world use to see how …

This study tests if a newer pacing method called left bundle branch pacing (LBBP) is better than standard right ventricular pacing (RVP) at preserving heart function in 683 adults with atrioventricular block (a type of heart block). Participants will be randomly assigned to one o…

This study compares a new leadless pacemaker (Micra AV) to a standard dual-chamber pacemaker in 100 patients aged 70 and older with heart block. The goal is to see if the leadless version works just as well for exercise capacity. Participants are randomly assigned to receive one …

This study tests whether a new leadless pacemaker (Micra AV) is better than a traditional wired pacemaker for people aged 75 and older with heart block. The goal is to see if the leadless device improves quality of life, patient acceptance, and exercise ability. Eighty participan…

This registry follows 545 people with arrhythmia who received a heart ablation using the DiamondTemp system. Researchers will track how many stay free of their heart rhythm problem and how many have serious side effects over 12 months. The goal is to see how well the device works…

This study follows over 3,400 people who have already received the Aveir VR leadless pacemaker, a small device placed directly in the heart to treat slow heart rhythms. Researchers are using real-world medical records to check for complications up to 10 years after implantation. …

This study watches 40 adults who need a leadless pacemaker to see if where the device sits inside the heart changes heart rhythm or pumping strength. Researchers will use CT scans and ECGs to check heart function and valve leakage. The goal is to find the best spot for the pacema…

This study was designed to compare a newer pacing method (left bundle branch area pacing) with the standard method (right ventricular pacing) in patients who developed heart block after TAVR valve replacement. The goal was to see which method better preserves heart function and r…

This study is a nationwide registry in Taiwan that will follow 300 people who have or will receive a leadless pacemaker. The goal is to track how well the device works and any complications that may occur during or after the procedure. The study does not test a new treatment but …
