VENTRICULAR TACHYCARDIA

This study tests whether using a special computer tool (Ablation Index) can make a heart procedure faster and more effective for people with a history of heart attack and a dangerous fast heartbeat called ventricular tachycardia. About 100 adults with ischemic cardiomyopathy will…

This study is for adults with a serious heart condition called ventricular tachycardia that hasn't improved with standard treatments. Researchers want to see if giving a single, lower dose of radiation is just as safe and effective as splitting the same total dose into three sepa…

This study tests if a non-invasive radiation treatment (radio-ablation) works as well as the standard catheter procedure for controlling ventricular tachycardia, a dangerous fast heartbeat. About 244 adults with heart disease and an implanted defibrillator will be randomly assign…

This study tests a precise, high-dose radiation treatment (stereotactic radiotherapy) for people with a dangerous heart rhythm called ventricular tachycardia (VT) that hasn't improved with medication or standard procedures. The goal is to see if this radiation can reduce the numb…

This study tests a noninvasive radiation treatment for ventricular tachycardia (VT), a dangerous heart rhythm that can cause sudden death. It is for 12 people with heart disease who have not been helped by standard treatments like medication or catheter ablation. The approach use…

This study tests a new catheter that uses real-time MRI guidance to treat ventricular tachycardia, a fast and dangerous heart rhythm, in people with ischemic heart disease. About 64 participants will receive a targeted ablation (burning) of the heart tissue causing the problem. T…

This study tests whether a non-invasive radiation treatment (SBRT) can reduce dangerous heart rhythms as effectively as the standard catheter ablation procedure in 60 people with advanced heart disease. Participants will be randomly assigned to receive either radiation or cathete…

This study tests whether adding a special alcohol injection to the standard heart procedure (ablation) can better control dangerous heart rhythms in people with prior heart attacks. About 156 adults with an implanted defibrillator will be randomly assigned to get ablation alone o…

This study tests whether a sedative called dexmedetomidine can help people with a life-threatening heart rhythm problem called electrical storm. About 192 adults in intensive care will receive either the sedative or a placebo for 2-3 days. The goal is to see if the drug reduces d…

This study tests if using a tiny ultrasound camera inside the heart during ablation for ventricular arrhythmias can reduce the need for X-rays. About 70 adults with premature ventricular contractions or ventricular tachycardia will be randomly assigned to receive ablation with or…

This study tests if a non-invasive magnetic stimulation device can reduce dangerous heart rhythm episodes in people with ventricular tachycardia storm. About 60 adults who have had multiple episodes despite medication will be randomly assigned to real or sham stimulation. The mai…

This study is looking for new genes and blood markers that can help predict who will get arrhythmogenic cardiomyopathy (AVC), a genetic heart condition that can cause sudden cardiac arrest. Researchers will enroll 1000 people, including patients with AVC or unexplained cardiac ar…

This study compares two techniques used during a procedure to treat a dangerous fast heartbeat called ventricular tachycardia. The goal is to see which method better prevents the abnormal heart rhythm from coming back. About 222 people with an implanted defibrillator will be rand…

This study looks at how well a heart procedure called catheter ablation improves quality of life for people with a fast heart rhythm (ventricular tachycardia) who also have an implantable defibrillator. Researchers will ask 70 adults to fill out questionnaires about their health …

This study looks at why some people tolerate ventricular tachycardia (a fast, abnormal heart rhythm) better than others. Researchers will measure blood pressure and blood flow in the heart arteries of 70 people already scheduled for a heart catheter procedure. They want to see if…

This study tests a new imaging method to help doctors treat a dangerous heart rhythm called ventricular tachycardia (VT). VT happens when scar tissue in the heart creates an electrical "short circuit." Doctors use a procedure called catheter ablation to block that circuit, but cu…

This study is testing a new, paddle-shaped catheter designed to map abnormal heart rhythms (arrhythmias) in people with conditions like atrial fibrillation or ventricular tachycardia. About 60 participants will undergo a standard heart-mapping procedure using this investigational…

This study aims to understand why ventricular tachycardia (a fast, dangerous heart rhythm) happens in people with certain heart conditions. Researchers will measure the electrical signals in heart tissue from 10 participants to find the exact spots that cause the problem. The goa…

This study looks at 200 adults with early-onset atrial fibrillation (before age 60) who have certain genetic changes. Researchers will use cardiac MRI and electrical mapping during a scheduled heart procedure to see who is at risk for ventricular tachycardia, a dangerous fast hea…

This study looks at 90 people with a heart condition called mitral valve prolapse who need surgery to fix a leaky valve. Researchers want to see if the surgery reduces dangerous heart rhythms and changes scarring in the heart muscle. Participants will have heart scans and wear a …

This study looks at how blocking a nerve cluster near the spine (stellate ganglion block) changes the heart's electrical activity in 20 adults with ventricular tachycardia who are already scheduled for a catheter ablation. Researchers will measure heart tissue recovery time and w…
