Ventricular tachycardia

This early study tests a new catheter technique called VINTAGE for people with ventricular arrhythmia that hasn't improved with standard treatment. The procedure uses special catheters to reach and destroy heart tissue causing the abnormal rhythm. Thirty adults will be enrolled a…

This study tests a new system that combines a leadless pacemaker with a subcutaneous defibrillator to treat dangerously fast heart rhythms. The devices communicate wirelessly to deliver pacing therapy without wires inside the heart. About 300 people at risk for ventricular tachyc…

This study tests a new device that uses extreme cold (cryoablation) to treat a fast, dangerous heart rhythm called sustained monomorphic ventricular tachycardia. About 206 adults with this condition will receive the freezing treatment. The goal is to see if it safely stops the ab…

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 is testing a new type of catheter that uses pulsed electrical fields to treat certain heart rhythm problems, specifically premature ventricular contractions (PVCs) and ventricular tachycardia. The device, called Farapoint, is designed to map and ablate (destroy) the ti…

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 a new device that combines two heart therapies: one to strengthen heartbeats and another to stop dangerous rhythms. About 300 adults with heart failure and a weak heart pump will get the device. Researchers will check if it safely converts life-threatening heart …

This study tests a new catheter that uses two types of energy (radiofrequency and pulsed field) to destroy the tiny areas of heart tissue causing ventricular tachycardia, a fast and dangerous heart rhythm. Thirty patients with recurrent episodes will undergo the procedure. The go…

This study compares two ways of programming implantable defibrillators (ICDs) in 398 Japanese patients. One group uses early, multiple bursts of rapid pacing (ATP) to stop dangerous heart rhythms, while the other uses a longer detection time before pacing. The goal is to see whic…

This early study tests a new catheter that uses two types of energy (radiofrequency and pulsed field) to treat rapid heartbeats from the lower chambers. Ten adults with drug-resistant ventricular arrhythmias will receive the procedure. The main goal is to check safety and see if …

This study tests a new mapping method for ventricular tachycardia (VT) ablation that avoids purposely triggering VT. Instead, it uses special software to identify slow-conduction areas during normal heart rhythm. The goal is to see if this approach reduces VT recurrence, death, o…

This study tests a new type of wire (lead) for implantable heart devices like ICDs or CRT-Ds. The lead is designed to pace the heart's natural conduction system, which may work better than standard pacing. About 414 adults who need these devices will be followed for 3 months to c…

This trial tests whether a procedure called catheter ablation works better than anti-arrhythmic drugs for people with structural heart disease who have had a dangerous fast heart rhythm (ventricular tachycardia). About 162 participants will be randomly assigned to either ablation…

This early study tests a new type of lead (a wire) for an implantable cardioverter-defibrillator (ICD) in 19 people who need one. The lead is placed under the breastbone to deliver a shock if the heart beats dangerously fast. The goal is to see if it is safe and works well enough…

This study is checking how well a special pacemaker feature called iATP works in everyday medical practice. The iATP automatically sends tiny, painless electrical pulses to stop a fast, dangerous heart rhythm called ventricular tachycardia. Researchers are tracking 2,200 people w…

This study follows 62 people with non-ischemic structural heart disease who have recurrent, drug-resistant ventricular tachycardia. They are treated with the FlexAbility SE ablation catheter, which uses heat to destroy small areas of heart tissue causing the abnormal rhythm. Rese…

This study asks whether tiny RNA molecules in the blood can signal a higher risk of dangerous heart rhythms in people who have heart failure after a heart attack and use an implanted defibrillator. Researchers collect blood samples from 57 participants and compare RNA patterns be…

This study tests a new, non-invasive ultrasound method called electromechanical wave imaging (EWI) to see if it can more accurately locate and diagnose heart rhythm problems compared to standard tests. About 322 adults already scheduled for a heart procedure will get an EWI scan …

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 looks at heart rhythm problems in people with hypertrophic cardiomyopathy, a condition where the heart muscle is thicker than normal. Researchers want to see how often new rhythm issues like atrial fibrillation happen, and whether sleep apnea plays a role. About 260 ad…

This study collects blood or skin samples from 100 adults with inherited heart rhythm disorders (like Long QT Syndrome or Brugada Syndrome) and healthy volunteers. Researchers will turn these samples into stem cells and then into heart cells to study how these diseases work and t…

This study is a large international registry that collects information from patients who have a heart ablation procedure for ventricular tachycardia or premature ventricular contractions. The goal is to track how well the procedure works and any complications, helping doctors imp…
