Primary Outcome Measures:
  • Primary Outcome Measure [ Time Frame: 7 days and 1 year ] [ Designated as safety issue: Yes ]

    The long-term primary safety endpoint is the percentage of subjects that expire from all-cause mortality within 12-months post ablation.

    The acute primary safety endpoint is the percentage of subjects experiencing cardiovascular-specific adverse events (CSAE) within 7 days of the ablation procedure.



Secondary Outcome Measures:
  • Secondary Outcome Measure [ Time Frame: Yearly ] [ Designated as safety issue: Yes ]
    Acute effectiveness, chronic effectiveness, pre/post assessment for hospitalization for heart failure, hospitalization for arrhythmia, ICD shocks (for subjects with implantable defibrillators), Ejection Fraction (EF), Quality of Life (QOL), and NYHA classification. Additionally, incidence of cardiac transplantation and mortality will be evaluated.


Estimated Enrollment: 249
Study Start Date: January 2007
Estimated Study Completion Date: December 2012
Estimated Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: NAVISTAR® THERMOCOOL® Catheter
    The primary objective is to provide additional, corroborative safety data for the NAVISTAR THERMOCOOL catheter for the treatment of subjects with sustained, monomorphic VT or incessant VT associated with coronary artery disease
Detailed Description:

This study is a prospective, non-randomized, single-arm, multi-center condition of approval evaluation. The device is currently FDA approved for commercial distribution. Subjects with ischemic ventricular tachycardia will be considered for the condition of approval study. This study will be conducted at up to 30 centers in a minimum of 249 evaluable subjects.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Four or more documented spontaneous episodes of sustained ventricular tachycardia, OR incessant VT (present 50% of the time with intervention for a period >12 h) refractory to medication and cardioversion due to prior myocardial infarction that have occurred in the last six months.
  • For patients with ICDs: Documented episodes must be four or greater for entry into the study.
  • For patients without ICDs: Documented episodes must be two or greater within two months and the assessment will be performed by a review of ECGs and hospitalization records
  • Failed therapy with an antiarrhythmic drug or ICD due to spontaneous recurrence of symptomatic ventricular tachycardia.
  • Left ventricular ejection fraction > 10% as estimated by echocardiography, contrast ventriculography or radionuclide imaging within the previous 90 days.
  • Age 18 years or older.
  • Signed Patient Informed consent form
  • Able and willing to comply with all pre-, post-, and follow-up testing requirements

Exclusion Criteria:

  • Definite protruding left ventricular thrombus on pre-ablation echocardiogram.
  • Myocardial infarction within the preceding 2 months. Patients with incessant VT (present 50% of the time with intervention for a period >12 h) may be enrolled if their MI is at least 3 weeks old.
  • Patients with idiopathic VT.
  • Other disease process likely to limit survival to less than 12 months.
  • Class IV heart failure.
  • Serum creatinine of > 2.5 mg/dl.
  • Thrombocytopenia or coagulopathy.
  • Contraindication to heparin.
  • Women who are pregnant.
  • Cardiac surgery (i.e. ventriculotomy, atriotomy) within the past 2 months. Patients with incessant VT (present 50% of the time with intervention for a period >12 h) may be enrolled if their surgery is at least 3 weeks old.
  • Acute illness or active systemic infection.
  • Unstable angina.
  • Severe aortic stenosis or flail mitral valve.
  • Uncontrolled heart failure.
  • Significant congenital anomaly or medical problem that in the opinion of the principal Investigator would preclude enrollment in the study.
  • Enrolled in an investigational study evaluating another device or drug.
