Venous Ethanol for Ventricular Tachycardia (VELVET Trial)

Phase 2
Recruiting
Led By Miguel Valderrabano, MD
Research Sponsored by The Methodist Hospital Research Institute
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Male and female, ages of 18 and 85 years and with a prior ICD implant
Diagnosed with ischemic cardiomyopathy: Prior myocardial infarction (pathological Q waves or imaging evidence of regional myocardial akinesis/thinning in the absence of a non-ischemic cause)
Timeline
Screening 3 weeks
Treatment Varies
Follow Up 0-12 months
Awards & highlights
No Placebo-Only Group

Summary

This trial is comparing two treatments for a heart condition called ischemic ventricular tachycardia. One treatment involves using radiofrequency ablation alone, while the other treatment combines radiofrequency ablation

Who is the study for?
This trial is for men and women aged 18-85 with ischemic cardiomyopathy, evidenced by a past heart attack or heart muscle issues. They must have had multiple rapid heartbeat episodes treated with pacing or drugs, an ICD shock, or documented ventricular tachycardia. Candidates should be eligible for radiofrequency ablation therapy and willing to follow the study's procedures.
What is being tested?
The VELVET clinical trial is testing two treatments for severe rapid heartbeat due to heart muscle damage: one group receives standard catheter ablation while the other gets additional venous ethanol treatment. Participants are randomly assigned to either method.
What are the potential side effects?
Potential side effects may include discomfort at the catheter insertion site, bleeding, infection risk from the procedure, possible damage to blood vessels or heart tissue from ablation or ethanol injection, arrhythmias (irregular heartbeats), and rarely more serious complications.
