Safety and Effectiveness of the Sphere-9™ Catheter and Affera™ Ablation System for the Treatment of Ventricular Tachycardia (Sphere VT)
Safety and Effectiveness of the Sphere-9™ Catheter and Affera™ Ablation System for the Treatment of Ventricular Tachycardia
Sphere VT is a prospective, multi-center, single-arm, unblinded pivotal clinical study. Adult subjects with recurrent, sustained, monomorphic ventricular tachycardia (MMVT) due to prior myocardial infarction (MI) will be enrolled and treated with the Sphere-9 Catheter and Affera Ablation System.

Descripción
Inclusion Criteria:
- Prior myocardial infarction (MI).
- At least one episode of sustained (continuous for >30 seconds or requiring ICD intervention for termination) monomorphic ventricular tachycardia within the 6 months prior to enrollment.
- Recurrence of sustained ventricular tachycardia despite Class I or III antiarrhythmic drug therapy or ICD intervention.
- Implanted with an implantable cardiac defibrillator (ICD) or CRT-D for at least 2 months prior to the ablation procedure.
- Age 18 through 85 years old.
- Willing and able to provide informed consent.
- Willing and able to comply with all pre-, post-, and follow-up testing requirements.
Exclusion Criteria:
- Incessant VT necessitating hemodynamic support prior to the ablation procedure.
- Unstable polymorphic VT or ventricular fibrillation (VF).
- Idiopathic VT or VT of non-ischemic cardiomyopathy.
- VT secondary to electrolyte imbalance, active thyroid disease, or any other reversible or non-cardiac cause (e.g., drug-induced arrhythmia).
- VT or VF thought to be from channelopathies.
- More than two prior VT ablations at any time, more than one prior VT ablation within 12 months prior to the ablation procedure, or any VT ablation within 4 weeks prior to the ablation procedure.
- Sarcoidosis.
- Hypertrophic cardiomyopathy, except when due to an apical aneurysm.
- Unstable angina.
- Active myocardial ischemia.
- Type 1 myocardial infarction within 2 months (60 days) prior to the ablation procedure.
- Any percutaneous coronary intervention performed in a setting of unstable angina or acute MI (STEMI or non-STEMI) within 2 months (60 days) prior to the ablation procedure. Note: elective PCI performed during elective angiogram would be excluded only if occurring within 30 days prior to the ablation procedure.
- Any cardiac surgery within 2 months (60 days) prior to the ablation procedure. Note: ICD lead implant/replacement falls under this exclusion, but ICD generator-only replacement does not.
- Left ventricular ejection fraction (LVEF) <15%.
- NYHA Class IV heart failure.
- Decompensated heart failure.
- Extravascular ICD (EV-ICD) or subcutaneous ICD (S-ICD)
- Currently receiving support, or anticipated to receive support prior to the index ablation procedure, via extracorporeal membrane oxygenation (ECMO).
- Circulatory/ventricular assist device (VAD; surgical or percutaneous) implanted, planned or required for the procedure.
- Severe aortic or mitral stenosis, or severe aortic or mitral regurgitation.
- Presence of prosthetic valve in the aortic or mitral valve.
- Patients with advanced COPD (on home oxygen).
- Presence of intracardiac tumor or other abnormality that precludes vascular access, catheter introduction, or manipulation.
- Thromboembolic event (stroke or transient ischemic attack) within 6 months (180 days) prior to the index ablation procedure or with neurologic deficit.
- Left atrium (LA) or left ventricle (LV) intracardiac thrombus on imaging.
- Severe bleeding, clotting or thrombotic disorder, or thrombocytopenia (defined as platelet count <80,000).
- Contraindication to anticoagulation.
- End-stage renal disease (requiring dialysis).
- Acute illness, active infection, or sepsis.
- Life expectancy less than 12 months.
- Any woman known to be pregnant or breastfeeding, or any woman of childbearing potential who is not on a reliable form of birth regulation method or abstinence.
- Body mass index >45 kg/m2.
- Known ongoing drug or alcohol dependency.
- Current or anticipated participation in any other ongoing study of a drug, device, or biologic during the duration of the study not pre-approved by the Sponsor.
- Vulnerable subjects (such as a prisoner, handicapped or mentally disabled person, or person under tutelage or guardianship).
- Any other condition that, in the opinion of the investigator, would preclude enrollment in this study or compliance with follow-up requirements or would pose a significant hazard to the subject if an ablation procedure were performed.

Primary Safety
Periodo de tiempo: As applicable, within 7 days or 3 months after the index ablation procedure
|
A pre-defined list of device- or procedure-related SAEs, as adjudicated by the Clinical Events Committee (CEC), occurring within 7 days after the index ablation procedure (or within 3 months after the index ablation procedure for any esophago-pericardial fistula/esophageal perforation) will be considered a primary safety event. |
As applicable, within 7 days or 3 months after the index ablation procedure

Primary Effectiveness
Periodo de tiempo: Through 6 months after the index ablation procedure
|
Freedom from recurrence of sustained monomorphic VT (MMVT) in the absence of new or increased dose of Class I or III antiarrhythmic drugs (AAD) through 6 months after the index ablation procedure. |
Through 6 months after the index ablation procedure
