The goal of this trial is to see if a tool that may reduce wait times will reduce bad outcomes in participants on the TAVI waitlist. The main questions it aims to answer are:

• How many deaths, hospitalizations, or urgent TAVI procedures take place while participants wait
• Days alive and out of hospital at 30 days and 12 weeks, total health care costs, and wait times

Researchers will compare usual wait times to see if the tool reduces death, hospitalizations, and urgent procedures.

Inclusion Criteria:

• All patients referred for TAVI who are 18 years or older at one of 11 TAVI hospitals

Exclusion Criteria:

• Any inpatient referrals who have an urgent inpatient TAVI on the same admission
• Any referral during the 1-month transition period

No personal information or personal health information is being collected from participants.
