Outcome Measures

Primary Outcomes (4)

  • All-cause mortality

    To analyse the safety of B-blocker discontinuation, the all-cause mortality, as part of a composite endpoint, is assessed within 30 days after transcatheter aortic valve replacement (TAVR).

    At 30 days

  • Re-hospitalization due to heart failure

    To analyse the safety of B-blocker discontinuation, the incidence of re-hospitalization due to heart failure, as part of a composite endpoint, is assessed within 30 days after TAVR. Re-hospitalization due to heart failure is defined as an admission occurring after the index hospitalization or study enrollment, where new or worsening heart failure is the primary reason for a hospital stay exceeding 24 hours. This determination is based on symptoms and signs of heart failure, confirmed by diagnostic tests, and requires treatment with intravenous or mechanical heart failure therapies. This includes both primary (cardiac-related) and secondary (non-cardiac-related) causes.

    At 30 days

  • Stroke Rate

    To analyse the safety of B-blocker discontinuation, the incidence of stroke, as part of a composite endpoint, is assessed within 30 days after TAVR.

    At 30 days

  • Severe arrhythmia requiring treatment

    To analyse the safety of B-blocker discontinuation, the incidence of severe arrhythmia that requires treatment, as part of a composite endpoint, is assessed within 30 days after TAVR. Severe arrhythmia requiring treatment are e.g. new onset atrial fibrillation/flutter, ventricular tachycardia/ventricular fibrillation, new atrioventricular block (AB, first-, second- or third-degree), new left bundle branch block, new right bundle branch block, new severe bradycardia or tachycardia (\<40bpm or \>120bpm).

    At 30 days

Secondary Outcomes (6)

  • Permanent pacemaker implantation Rate

    At 30 days and 1 year

  • Stroke Rate

    At 30 days and 1 year

  • All-cause mortality

    At 30 days and 1 year

  • Cardiovascular mortality

    At 30 days and 1 year

  • Re-hospitalization due to heart failure

    At 30 days and 1 year

  • +1 more secondary outcomes

Other Outcomes (1)

  • Health economic assessment

    At 30 days and 1 year

Study Arms (2)

Pausing group

EXPERIMENTAL

Subjects in the pausing group will stop their B-blocker medication 72h before the scheduled transcatheter aortic valve replacement (TAVR) procedure. Post-procedural B-blocker therapy will be resumed 72h after the procedure using the same type and dosage as prescribed before.

Other: Transcatheter aortic valve replacement in the absence of B-blocker treatment

Control group

OTHER

Subjects in the control group will keep their B-blocker medication in their prescribed dose during the scheduled TAVR procedure.

Other: Transcatheter aortic valve replacement

Interventions

Transcatheter aortic valve replacement (TAVR) is performed in patients that temporarily pause B-blocker treatment.

Pausing group

Transcatheter aortic valve replacement (TAVR) is performed in patients that do not temporarily pause B-blocker treatment.

Control group
