Venous Ethanol for Ventricular Tachycardia

Summary

Comparative effectiveness randomized clinical trial, comparing endocardial radiofrequency ablation alone vs radiofrequency ablation combined with venous ethanol in patients with ischemic ventricular tachycardia -Venous Ethanol for Left Ventricular Ischemic Ventricular Tachycardia -VELVET clinical trial

Eligibility

Inclusion Criteria:

* 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)
* One of the following VT events (within last 6 months): a) ≥3 episodes of VT treated with anti-tachycardia pacing (ATP) or anti-arrhythmic drugs; b) ≥1 appropriate ICD shocks; c) ≥3 VT episodes within 24 hr; d) sustained VT below detection rate of the ICD documented by EKG/cardiac monitor
* Patients deemed candidates for RF ablation of VT
* Able and willing to comply with pre-, post-, and follow-up requirements
* Willing to sign the informed consent

Exclusion Criteria:

* Serum creatinine \>1.5 mg/dL, or creatinine clearance \<30 ml/min
* Left ventricular (LV) ejection fraction ≤10%
* Mobile LV thrombus on echocardiography
* Absence of vascular access to the LV
* Disease process likely to limit survival to \<12 months
* New York Heart Association class IV heart failure
* Cardiac surgery within the past 2 months (unless VT was incessant),
* Acute coronary syndrome in the past 2 months (acute thrombus diagnosed by coronary angiography, or dynamic ST segment changes demonstrated on EKG)
* Another reversible cause of VT (e.g. electrolyte abnormalities, drug-induced arrhythmia)
* Severe aortic stenosis or mitral regurgitation with a flail leaflet
* Pregnancy
* Unwilling or unable to provide informed consent
* Covid-19 positive testing within 14 days of randomization procedure
* Enrolled, or planning to get enrolled, in another research study during his/her participation on the Velvet trial
