Measure
1: Access to HMSC
Full functionality of the Home Monitoring System for an early optimization of CRT and management of AF with a full access for the treating physician to the HMSC Home Monitoring (CRT and AF therapy with Home Monitoring feature): CRT and AF therapy according to medical guidelines, where the physician receives relevant daily data from the implant via Home Monitoring
2: No Access to HMSC
Limited access of the treating physician to the HMSC where only events regarding implant and lead status will be generated and sent to the physician. Home Monitoring (CRT and AF therapy, without Home Monitoring): CRT and AF therapy according to medical guidelines, without daily data transmission from the implant via Home Monitoring (except for the safety data on device integrity)

Outcome measures

Outcome measures
Measure
1: Access to HMSC
n=88 Participants
Full functionality of the Home Monitoring System for an early optimization of CRT and management of AF with a full access for the treating physician to the HMSC Home Monitoring (CRT and AF therapy with Home Monitoring feature): CRT and AF therapy according to medical guidelines, where the physician receives relevant daily data from the implant via Home Monitoring
2: No Access to HMSC
n=75 Participants
Limited access of the treating physician to the HMSC where only events regarding implant and lead status will be generated and sent to the physician. Home Monitoring (CRT and AF therapy, without Home Monitoring): CRT and AF therapy according to medical guidelines, without daily data transmission from the implant via Home Monitoring (except for the safety data on device integrity)

Standard Deviation 52.5
16.0 Days lost per patient
Standard Deviation 47.8

SECONDARY outcome

Population: Endpoint was not evaluated because of the insignificant result for the primary hypothesis and early study discontinuation due to low enrollment

Analysis of the fraction of patients with worsened composite clinical score in the two treatment arms.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: 12 months

Population: Endpoint was not evaluated because of the insignificant result for the primary hypothesis and early study discontinuation due to low enrollment

Analysis of the change in left ventricular end-systolic volume, left atrial diameter, left ventricular EF, and the degree of mitral regurgitation from enrollment to the end of the follow-up in the two treatment arms

Outcome measures
