Descripción detallada

A prospective, single-arm, multi-center, open label, pre-market, clinical study designed to provide safety and efficacy data regarding the use of the Adagio System in the treatment of scar-mediated SMVT in ischemic and non-ischemic patients. Study subjects will include patients who experience recurrent SMVT and are scheduled for an endocardial VT ablation. Study subjects must have an Implantable Cardioverter Defibrillator (ICD) prior to the cryoablation procedure.

The VTS study is being initiated to collect safety and effectiveness data and support future PMA supplement marketing application.

  • EC 3 VTs due to any of the following causes:

    1. Idiopathic VT
    2. Automaticity or triggered activity
    3. Bundle Branch Reentry (BBR)
    4. Any focal tachycardia (e.g., papillary, RVOT)
    5. Ventricular tachycardia secondary to electrolyte imbalance, active thyroid disease, or any other reversible or non-cardiac cause

  • EC 4 NICM patients only, if any of the following apply:

    1. Congenital condition that limits access to the left or right ventricles
    2. Severe aortic or mitral stenosis, severe mitral regurgitation, or severe aortic insufficiency
    3. Active inflammatory processes (e.g., myocarditis) within the past 120 days
    4. Sarcoidosis
    5. Hypertrophic cardiomyopathy
    6. Drug- or alcohol-induced cardiomyopathy
  • EC 5 Any VT ablation within 4 weeks prior to enrollment
  • EC 6 More than one prior (>4 weeks) VT ablation or prior surgical treatment for VT within the past 2 years
  • EC 7 Cardiogenic shock, unless it is due to incessant monomorphic VT

  • EC 8 Any other cardiovascular conditions as described below:

    1. Class IV heart failure
    2. Aortic aneurysm
    3. Previous cardiac surgery or percutaneous coronary intervention within 60 days prior to index procedure
    4. Interatrial baffle, closure device, patch, or PFO occlusion device
    5. Coronary artery bypass graft (CABG) procedure within six (6) months prior to the ablation procedure
    6. Acute MI or unstable angina in the previous 60 days
    7. Mechanical mitral or aortic valve
    8. Cardiac myxoma
    9. Significant congenital heart disease
  • EC 9 Acute illness or active systemic infection

  • EC 16 Pregnant, or anticipated pregnancy during study follow-up
  • EC 17 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
  • EC 18 Any other condition (e.g., ARVC with extensive free wall scarring) 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, candidate for heart transplantation, patient with ventricular assist device, or terminal illness with a life expectancy less than 12 months)

¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Primary Safety Endpoint
Periodo de tiempo: 7 days following the ablation procedure

Primary Safety Endpoint is freedom from definite or probable device or procedure related Major Adverse Events (MAEs) that occur within 7 days following the cryoablation procedure.

Events will be adjudicated by an independent Clinical Events Committee (CEC). MAEs include any of the following: • Death • Acute myocardial infarction • Cardiac perforation/pericardial tamponade • Cerebral infarct or systemic embolism • Major bleeding requiring transfusion • Acute Mitral, Tricuspid or Aortic valve damage resulting in moderate or severe regurgitation • Access site complications requiring medical or surgical intervention • Pericarditis • Heart block requiring a permanent pacemaker • Other serious adverse device effects (SADEs), including TIAs, adjudicated by an independent Clinical Events Committee (CEC) to be probably or definitely related to the Adagio System.
7 days following the ablation procedure
Primary Efficacy Endpoint
Periodo de tiempo: 6 months after the procedure
Primary Efficacy Endpoint is defined as freedom from recurrent sustained MMVT in the absence of a new AAD or increase in dose of a pre-ablation AAD for VT management at 6 months following the ablation procedure, where sustained MMVT is defined as continuous MMVT for > 30 seconds (programmed monitoring zone only), or MMVT requiring appropriate ICD intervention regardless of duration. All ICD interrogation reports will be adjudicated by an independent VT Event Committee (VTEC) to support the primary efficacy endpoint.
6 months after the procedure
Primary Procedural Endpoint
Periodo de tiempo: at the end of the ablation procedure
Primary Procedural Endpoint is defined as non-inducibility of any VT targeted for ablation at the end of the procedure
at the end of the ablation procedure

Medidas de resultado secundarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Secondary Safety Endpoint
Periodo de tiempo: 12-months post ablation procedure
Secondary Safety Endpoint is defined as freedom from definite or probable device or procedure related Serious Adverse Events (SAEs) within 12 months following the cryoablation procedure. Events will be adjudicated by an independent Clinical Events Committee (CEC).
12-months post ablation procedure
Secondary Efficacy Endpoint
Periodo de tiempo: 12-months post ablation procedure
Secondary Efficacy Endpoint is defined as freedom from Ventricular Tachycardia lasting longer than 30 seconds or appropriate ICD intervention at 12 months
12-months post ablation procedure
