Picasso NAV High-Density Mapping Catheter for Signal Analysis of Complex Arrhythmias - First-In-Man

Phase 1

Completed

• Conditions: Arrhythmias
• Interventions: Procedure: Ablation procedure; Device: Picasso NAV Catheter

• Registration Number: NCT02110004
• Lead Sponsor: Biosense Webster, Inc.

Brief Summary

The primary purpose of the First-In-Man clinical investigation is to assess the Picasso NAV Catheter's ability to collect intracardiac signals within the desired chambers (atrial and/or ventricle) in the heart for the analysis of complex arrhythmias.

Inclusion Criteria

Subjects must meet all of the following inclusion criteria to be eligible for participation in this clinical investigation.

1. Age > 18 years or older.
2. Patients who have signed the Patient Informed Consent Form (ICF)
3. Patients who are scheduled to undergo a clinically-indicated catheter ablation procedure for the management of a complex arrhythmia. (Patients having undergone a previous ablation procedure may be included.)
4. Subjects who have failed at least one antiarrhythmic drug (AAD) (including AV nodal blocking agents such as beta blockers and calcium channel blockers) as evidenced by recurrent symptomatic complex arrhythmia, or intolerable to the AAD
5. Complex arrhythmias (including atrial fibrillation, atypical flutter, ventricular tachycardia) defined as patients who have been diagnosed with a complex arrhythmia anytime within the last 5 years prior to enrolment. Symptoms may include, but are not restricted to, palpitations, shortness of breath, chest pain, fatigue, left ventricular dysfunction, or other symptoms, or any combination of the above.
6. At least one episode of the complex arrhythmia must have been documented by ECG, Holter, loop recorder, telemetry, implanted device, or transtelephonic monitoring within 12 months of enrollment.
7. Able and willing to comply with all pre-, post-, and follow-up testing and requirements.

Exclusion Criteria

Subjects who meet any of the following exclusion criteria are not eligible for enrollment.

1. A complex arrhythmia secondary to a reversible cause.
2. Atrial arrhythmias: patients with a left atrial size >55 mm (echocardiography, parasternal long axis view).
3. Left Ventricular Ejection Fraction < 25%
4. NYHA Class III or IV
5. Significant congenital anomaly or medical problem that in the opinion of the investigator would preclude enrollment in this study.
6. Atrial arrhythmias: patients with structural atrial disease such as a prior history of atriotomy from prior atrial surgery, presence of an atrial septal defect, and/or presence of an atrial septal closure patch.
7. History of or current blood clotting or bleeding abnormalities, contraindication to systemic anticoagulation (i.e., heparin, warfarin, dabigatran, or a direct thrombin inhibitor)
8. Subjects that have ever undergone valvular cardiac surgical procedure (ie, ventriculotomy, atriotomy, and valve repair or replacement and presence of a prosthetic valve)
9. Any cardiac surgery within the past 60 days (2 months) (includes PCI)
10. Concurrent enrollment in a study evaluating another device or drug.
11. A complex arrhythmia secondary to electrolyte imbalance, thyroid disease, or non-cardiac cause.
12. Presence of intra-cardiac thrombus or myxoma, interatrial baffle or patch, tumor or other abnormality that precludes catheter introduction or manipulation.
13. Presence of a condition that precludes vascular access.
14. Women of child bearing potential whom are pregnant, lactating, or planning to become pregnant during the course of the clinical investigation
15. Active illness or active systemic infection or sepsis.
