  Purpose
The study is designed to collect data of the performance and confirm the safety of the DX (Diagnostic eXtension) functionality in the Lumax 640/470 HF-T in patients with permanent atrial fibrillation and CRT-D indication according to current ESC guidelines. The DX functionality is a feature, which can be activated in the Lumax 640/740 HF-T when connected to the LinoxSMART S DX right ventricular lead. The combination of these devices enable atrial sensing via a sensing dipole in the ventricular lead and therefore reduces the number of implanted leads without sacrificing atrial information. Atrial pacing can not be provided but is not needed in patients with permanent atrial fibrillation.

Condition
Atrial Fibrillation Heart Failure

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective

Primary Outcome Measures:
  • Quality of IEGM recording [ Time Frame: 3 months ]
    to assess if the IEGM Online recordings of the Lumax 640/740 HF-T with DX functionality provide adequate quality to classify the atrial rhythm

  • Safety of the Lumax 640/740 HF-T with DX functionality based on the Serious Adverse Device Effects related to the DX functionality [ Time Frame: 3 months ]
    to assess the safety of the Lumax 640/740 HF-T by the analysis of Serious Adverse Device Effects which are related to the DX functionality

  • Safety of the Lumax 640/740 HF-T with DX functionality based on all, serious and non-serious, Adverse Device Effects related to DX functionality [ Time Frame: 3 months ]
    to assess the safety of the Lumax 640/740 HF-T with DX functionality by the analysis of all (serious and non-serious) Adverse Device Effects which are related to the DX functionality

  • Number of patients with maintenance of diagnosis of permanent AF [ Time Frame: 3 months ]
    to investigate whether the diagnosis of permanent AF at enrollment is maintained after device implantation


Enrollment: 18

Criteria

Inclusion Criteria:

  • Patient eligible for programming of DX functionality according to the physicians` decision
  • Patient is willing and able to comply with the CIP and provided written informed consent
  • Patient accepts Home Monitoring® concept and has sufficient GSM/GPRS coverage

Exclusion Criteria:

  • Patients with any contraindication to CRT-D therapy
  • Patients listed for heart transplantation
  • Life expectancy less than 12 months
