Brief summary
The purpose of this study is to evaluate the quality of life, patient acceptance and exercise capacity with leadless compared to transvenous pacing in elderly patients with new-onset high-grade atrioventricular block. Consecutive patients with high-grade atrioventricular black and preserved sinus node function with indication for permanent pacemaker implantation according to the latest european guidelines, are included in a prospective, partly patient and accessor blinded and partly open label, 1:1 randomized combined parallel and cross-over trial to implantation with 1) a Micra AV Transcathter Pacing System or 2) an Azure XT DR dual chamber pacemaker.
Interventions
Patients are implanted with a leadless Micra AV TPS
Patients are implanted with a transvenous Azure XT DR pacemaker

Eligibility
Inclusion criteria
* First time pacemaker implantation on class I or II ESC recommendations for AVB with an expected amount of right ventricular pacing \>80% of the time, * Age 75 years or older * Intact sinus node function * Expected survival more than 12 months based on clinical evaluation * Able to provide informed consent
Exclusion criteria
* Persistent or previous cardiac implantable electronic device i.e., pacemaker, ICD, or CRT. * Persistent, or chronic atrial fibrillation * Reversible AVB * Transient AVB due to ongoing ischemia * Heart failure NYHA class III-IV * Heart failure with branch block and indication for CRT implantation, irrespective of NYHA class * Indication for primary or secondary prophylactic ICD implantation * Acute myocardial infarction (AMI) within 3 months * Severe chronic pulmonary disease with pulmonal hypertension limiting exercise capacity * Expected survival \< 12 months based on clinical evaluation * Performing high intensity sport * Participation in another trial with experimental treatment * Contraindication against device implantation (e.g., concurrent infection) * Failure to provide informed consent
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Quality of Life by SF36 | 7 months | Self-reported health-related quality of life as measured by Short-Form 36 quality of life questionnaire. The scale ranges from 0 to 100. 0 denotes minimal quality of life and 100 denotes maximum quality of life. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Patient Acceptance by FPAS | 7 months | Self-reported patient acceptance as measured by Florida Patient Acceptance Scale. The scale ranges from 0-100. 0 denotes minimal device acceptance and 100 denotes maximal device acceptance. |
| Exercise capacity by 6MWT | 7 months | Exercise capacity as measured by 6-minute walk test |
