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: * Creatinine clearance \<25 cc/min (using Cockcroft-Gault equation) except for patients on dialysis. (Contrast induced nephropathy is irrelevant in end-stage renal disease patients on dialysis, in whom the concern for contrast-induced renal dysfunction is not there since there is no chance of further kidney damage). Additionally, patients on dialysis will be excluded from the imaging sub-study. * 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
