Study Population

This clinical investigation will enroll subjects of all genders who have recurrent, drug-refractory, sustained monomorphic ventricular tachycardia in patients with non-ischemic structural heart disease.

You may qualify if:

  • Patient or legally acceptable representative or parent/guardian (as applicable) must provide written informed consent prior to any clinical investigation-related procedure
  • Subjects who have recurrent, drug-refractory, sustained MMVT with non-ischemic structural heart disease and a clinical decision has been made to use FlexAbility SE for an ablation procedure prior to enrollment in the research study
  • Refractory (i.e. not effective, not tolerated or not desired) to at least one Class I/III anti-arrhythmic medication for treatment of MMVT
  • Implanted with a market released ICD or CRT-D prior to the Index Ablation Procedure
  • Able and willing to comply with all study requirements

You may not qualify if:

  • Documented or known intracardiac thrombus or myxoma
  • Active systemic infection
  • History of atriotomy or ventriculotomy within 4 weeks prior to the Index Ablation Procedure
  • Patients with prosthetic valves as the catheter may damage the prosthesis
  • Unable to receive heparin or an acceptable alternative to achieve adequate anticoagulation
