Catecholaminergic polymorphic ventricular tachycardia 1

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 trial tests whether an 8-week course of the immunosuppressive drug prednisone can reduce episodes of ventricular tachycardia (a potentially fatal fast heart rhythm) and improve heart function in people with non-ischemic cardiomyopathy and confirmed heart inflammation. Partic…

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 whether a new, more powerful 7 Tesla MRI can better detect scarring and swelling in the heart muscle of people with cardiomyopathy. Researchers will scan 13 adults aged 20-70 to see if the higher-resolution images improve diagnosis. The goal is to see if this adv…

This study gathers health information from children under 18 who have cardiomyopathy linked to mutations in the MYBPC3 gene. Researchers aim to map the disease's natural course, identify risk factors, and measure how it affects quality of life. By reviewing past and future medica…

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 small pilot study is testing whether a gentle, non-invasive electrical stimulation on the ear (auricular vagus nerve stimulation) can change how the heart's electrical system works. Ten people who are already scheduled for a heart procedure will receive the stimulation while…
