In this patient engagement study, patients and partners will attend a presentation, group meeting and responding to the survey to help the research team gage the acceptability of using a biological therapy to prevent cardiac arrhythmia. Patient Partners will also help to clarify which outcomes are important to patients, to ensure the selected outcomes align with patient interests.

There will be four study groups:

1. Heart patients who experienced a cardiac arrhythmia while in hospital,
2. Heart patients who did not experience a cardiac arrhythmia while in hospital,
3. Heart patients with an upcoming procedure that have not had a cardiac arrhythmia,
4. Members of the general public.

There will be a presentation, two surveys and a team meeting. Results will be compiled and analyzed.

Inclusion criteria:

• Upcoming or previous cardiac procedure.

Exclusion Criteria:

• Inability to complete an electronic survey or participate in a small group meeting.

Patients will be recruited from in house databases after confirming patients have agreed to participate in research.

IPD will not be shared
