VENTRICULAR TACHYCARDIA

This study tests a new, non-invasive radiation treatment against the standard catheter procedure for ventricular tachycardia, a life-threatening fast heart rhythm. About 244 adults with weak hearts and an implanted defibrillator will be randomly assigned to one of the two treatme…

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 a new catheter (Vision-MR 2.0) to treat ventricular tachycardia, a fast heart rhythm that can be life-threatening, in people with ischemic heart disease. About 64 participants will undergo a procedure to burn small areas of heart tissue causing the abnormal rhyth…

This study tests a one-time, targeted radiation treatment 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 cut the number of severe episodes by at lea…

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

This study tests a noninvasive radiation treatment for people with dangerous heart rhythms (ventricular tachycardia) caused by scarred heart tissue. The treatment aims to destroy the faulty electrical pathways in the scar using precise radiation beams, similar to cancer therapy. …

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

This study is testing whether a sedative medication called dexmedetomidine can help control a life-threatening condition called 'electrical storm,' where the heart's lower chambers beat dangerously fast and repeatedly. About 192 adult patients in intensive care units with this co…

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 tests a new guidance tool called Ablation Index to help doctors perform heart ablation more precisely in people with ventricular tachycardia (a fast, dangerous heart rhythm) and ischemic cardiomyopathy (weakened heart muscle from past heart attacks). The goal is to see…

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's arteries during a controlled fast pacing in 70 adults already scheduled for a heart cathe…

This study looks at how well treatments for a fast heart rhythm called ventricular tachycardia (VT) work by asking patients about their quality of life. About 70 adults with an implanted defibrillator (ICD) will fill out questionnaires before and after treatment, either with a ca…

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

This study is testing a new paddle-shaped catheter designed to map abnormal heart rhythms (arrhythmias) in the upper and lower chambers of the heart. About 60 people with conditions like atrial fibrillation or ventricular tachycardia will take part. The main goal is to check if t…

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

This study aims to understand why some people with heart disease develop dangerous heart rhythms called ventricular tachycardia. Researchers will measure the electrical signals in heart tissue during a routine procedure to identify which areas trigger the abnormal rhythm. The goa…

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…

This study tests a new imaging method to find the exact location of electrical 'short circuits' in the heart that cause dangerous rapid heartbeats. Researchers will use special body-surface electrodes and CT or MRI scans to create 3D maps before and after a standard ablation proc…

This study is looking for 1,000 people with a genetic heart condition called arrhythmogenic cardiomyopathy (AVC) or their family members. The goal is to discover new genes and blood markers that can predict who will get the disease, how it will progress, and who is at risk for da…
