CARA-VT RCT Trial Summary

This trialcompares an invasive procedure to non-invasive radio ablation to treat ventricular tachycardia, using a novel mapping tech.

Who is the study for?
This trial is for patients aged 55 or older with a type of heart disease called cardiomyopathy, poor heart function (ejection fraction ≤ 35%), and an implanted defibrillator. They must have experienced repeated rapid heartbeats despite previous treatments. Excluded are those unable to consent, women who may become pregnant not using effective birth control, severe heart failure patients, those with less than a year to live, prior chest radiotherapy recipients, participants in other trials, and anyone under 55.Check my eligibility
What is being tested?
The study compares two treatments for rapid heartbeat due to ventricular tachycardia: the standard invasive procedure using catheters versus a new non-invasive method using targeted radio waves guided by advanced ECG mapping technology. Patients will be randomly assigned to one of these treatment groups.See study design
What are the potential side effects?
Potential side effects from catheter ablation can include bleeding or infection at the insertion site and damage to the blood vessels or heart. Radio ablation might cause skin irritation where the rays enter the body and could potentially affect nearby organs.
