  Purpose

The ALternate site cardiac reSYNChronization (ALSYNC) study, a non-comparative, prospective, non-randomized, multi-national clinical investigation.

The purpose of this clinical investigation is to evaluate the safety and performance of the investigational atrial transseptal endocardial LV lead delivery system and the implant procedure for delivering the SelectSecure® Model 3830 lead into the Left Ventricle via a superior approach, and to evaluate the performance of the SelectSecure® Model 3830 lead in the Left Ventricle.

Primary Outcome Measures:
  • Percentage of patients free from lead, delivery system and implant related complications. [ Time Frame: Six months ]

Secondary Outcome Measures:
  • Percentage of patients with successful lead implant in the Left Ventricle via a superior approach. [ Time Frame: 6 Months ]
  • Ease of positioning the SelectSecure® Model 3830 using the Models 6227ATS, 6248HS, JS, or JL catheters. [ Time Frame: 6 Months ]
    To evaluate the ease of positioning of the above lead and catheters, a rating scale of Poor, Fair, Good, Very good, and Excellent will be used.

  • Left Ventricular pacing voltage threshold at 0.4 ms pulse width. [ Time Frame: 12 months ]
  • Left Ventricular sensed R-wave amplitude. [ Time Frame: 12 months ]
  • Left Ventricular pacing impedance. [ Time Frame: 12 months ]
  • Change in NYHA Class. [ Time Frame: 6 months ]
  • Change in 6 minute hallwalk. [ Time Frame: 12 Months ]
  • Change in Left Ventricular End-Systolic Volume. [ Time Frame: 6 months ]
  • Change in Left Ventricular Ejection Fraction. [ Time Frame: 6 months ]
  • Change in Left Ventricular End-Diastolic Diameter. [ Time Frame: 6 months ]
  • Change in Mitral Regurgitation. [ Time Frame: 6 months ]
  • Change in Brain Natriuretic Peptide (BNP)/N-Terminal-prohormone BNP levels. [ Time Frame: 6 months ]
