Brief Summary

Transcatheter aortic valve replacement (TAVR) is a well-established alternative to surgical aortic valve replacement (SAVR) for the treatment of patients with severe aortic stenosis regardless of surgical risk. While TAVR and SAVR share some of the benefits and risks, they importantly differ with regards to invasiveness, time to recovery, hemodynamics, as well as options for re-intervention and possibly valve durability. An early benefit of TAVR may be offset by late risks. Therefore, current guidelines of the European Society of Cardiology recommend an integration of patient values and preferences for the selection of the treatment modality. The objective of the TOGETHER trial is to investigate the efficacy of a structured shared decision making approach (SDM) to improve patient-centered outcomes for the choice between SAVR and TAVR. TOGETHER is an investigator-initiated, randomized, open-label, single-center clinical trial. A total of 140 patients referred for treatment of symptomatic severe aortic stenosis and deemed to undergo TAVR or SAVR according to heart team decision will be randomized in a 1:1 ratio to structured SDM or usual care.

Outcome Measures

Primary Outcomes (2)

  • Patient decisional conflict

    Assessed by decisional conflict scale (ranges from 0 to 100, with higher scores indicating a worse outcome)

    3 days post baseline visit

  • Patient decisional regret

    Assessed by the decision regret scale (ranges from 0 to 100, with higher scores indicating a worse outcome)

    30 days post TAVR/SAVR

Secondary Outcomes (11)

  • Patient-centered communication

    3 days post baseline visit

  • Patient knowledge about the treatment options and outcomes

    3 days post baseline visit

  • Patient procedural satisfaction

    3 days post baseline visit

  • Patient decisional satisfaction

    3 days post baseline visit; 30 days and 1 year post TAVR/SAVR

  • Incorporation of patient values

    3 days post baseline visit

  • +6 more secondary outcomes

Study Arms (2)

Structured SDM

OTHER

Structured shared decision making for the choice between SAVR and TAVR

Other: Structured SDM

Usual Care

OTHER

Usual care for the choice between SAVR and TAVR

Other: Usual Care

Interventions

The conversation between the heart team member and the patient will be structured according the adapted three-talk model for patients with symptomatic aortic stenosis and using the American College of Cardiology's decision aid for patients deciding between TAVR and SAVR

Structured SDM

Usual care will include baseline visits without a structured SDM approach. Usual care includes at least one decision making talk with a heart team member discussing information about the disease, treatment options as well as benefits and risks of each procedure.
