Eligibility
Inclusion criteria
* Meet standard indication for ICD/CRT-D therapy * First ICD/CRT-D implantation or upgrade from pacemaker * Duly signed informed consent form * Willing to participate for the whole study duration * Patient accepts Home Monitoring concept and is able to activate and use the CardioMessenger * Patient has a legal capacity and ability to consent
Exclusion criteria
* Meet a standard contraindication for an ICD/CRT-D therapy * Age \< 18 years * Pregnant or breast-feeding * Cardiac surgery planned within the next six months * Enrollment in another cardiac clinical investigation with active treatment arm * Mechanical tricuspid valve prosthesis or severe tricuspid valve disease * Known dexamethasone acetate intolerance
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| TD01 Pacing Threshold | 3 month follow-up | Non-inferiority of the pacing threshold compared to Linox TD. It is expected, that pacing thresholds of the TD01 leads will be statistically significant lower than 0.8V. Pacing threshold is the minimal electrical stimulus (voltage) required to produce consistent cardiac depolarization (heart contraction). Linox TD is another (predecessor) electrode that is used for comparison. |
| TD01 Sensing Amplitude | 3 month follow-up | Non-inferiority of the sensing amplitude compared to Linox TD. It is expected, that the sensing amplitudes of the TD01 leads will be statistically significant higher than 9.7mV. Sensing amplitude is the value for the measured voltage maximum (mV) during the ventricular depolarization (QRS complex during contraction). Linox TD is another (predecessor) electrode that is used for comparison. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| SADE-free Rate Related to TD01 | 3 month follow-up | SADE-free rate related to TD01. It is expected, that the SADE-free rate is higher than 0.9 (90%). SADE Free Rate is a safety parameter and defined as p = 1 - number of SADEs divided by the number of TD01 leads implanted. Whereby Serious Adverse Device Effects (SADEs) are accounted that relate to the TD01 ICD lead and were observed between implantation until the predefined follow-up time, e.g. the three month follow-up. |

Outcome results
TD01 Pacing Threshold
Non-inferiority of the pacing threshold compared to Linox TD. It is expected, that pacing thresholds of the TD01 leads will be statistically significant lower than 0.8V. Pacing threshold is the minimal electrical stimulus (voltage) required to produce consistent cardiac depolarization (heart contraction). Linox TD is another (predecessor) electrode that is used for comparison.

TD01 Sensing Amplitude
Non-inferiority of the sensing amplitude compared to Linox TD. It is expected, that the sensing amplitudes of the TD01 leads will be statistically significant higher than 9.7mV. Sensing amplitude is the value for the measured voltage maximum (mV) during the ventricular depolarization (QRS complex during contraction).

SADE-free Rate Related to TD01
SADE-free rate related to TD01. It is expected, that the SADE-free rate is higher than 0.9 (90%). SADE Free Rate is a safety parameter and defined as p = 1 - number of SADEs divided by the number of TD01 leads implanted. Whereby Serious Adverse Device Effects (SADEs) are accounted that relate to the TD01 ICD lead and were observed between implantation until the predefined follow-up time, e.g. the three month follow-up.
