About this trial
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 criteria
Qualifiers
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
Disqualifiers
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
