Inclusion Criteria:  Male or female the ages of ≥ 18 years Suitable for a catheter ablation due to Ischemic and/or non-ischemic symptomatic monomorphic Ventricular Tachycardia, also monomorphic is defined as a similar QRS configuration from beat to beat. Has or will be receiving an ICD prior to hospital discharge post procedure. Scheduled for a de novo VT ablation and refractory to at least one AAD, based on physician discretion and hospital standards (Refractory is defined as an AAD not able to treat the arrhythmia satisfactorily or inducing unwanted side effects). Subject has LVEF > 20%, confirmed by echo or comparable technique during baseline evaluation Willingness, ability, and commitment to participate in baseline and follow-up evaluations for the full length of the study Willingness and ability to give an informed consent  Exclusion Criteria:  In the opinion of the Investigator, any known contraindication to a ventricular tachycardia ablation, TEE, or anticoagulation, including but not limited to the identification of any cardiac thrombus or evidence of sepsis Any duration of continuous arrythmia that is not monomorphic ventricular tachycardia. Multiple mono morphic tachycardia is acceptable, but poly morphic VT is not. History of previous ablation or surgical treatment for ventricular tachycardia Ventricular tachycardia secondary to electrolyte imbalance, active thyroid disease, or any other reversible or non-cardiac cause  Structural heart disease as described below:  Aortic aneurysm Previous cardiac surgery, ventriculotomy or atriotomy (excluding atriotomy for CABG), Previous cardiac valvular surgical or percutaneous procedure, or prosthetic valve Interatrial baffle, closure device, patch, or PFO occlusion device IVC filter Coronary artery bypass graft (CABG) procedure within six (6) months prior to the ablation procedure Unstable angina or ongoing myocardial ischemia Severe Mitral or Aortic insufficiency or stenosis based on most recent TTE Cardiac myxoma Significant congenital anomaly Recent Myocardial Infarct (MI) or unstable angina, within 60 days prior to the ablation procedure Any previous history of cryoglobulinemia History of blood clotting or bleeding disease Any prior history of documented cerebral vascular accident (CVA), TIA or systemic embolism (excluding a post-operative DVT), within 6 months. Pregnant, anticipated during study follow-up Current enrollment in any other study protocol where testing or results from that study may interfere with the procedure or outcome measurements for this study Any other condition that, in the judgment of the investigator, makes the patient a poor candidate for this procedure, the study or compliance with the protocol (includes vulnerable patient population, mental illness, addictive disease, terminal illness with a minimal life expectancy as it pertains to follow up)
