Background

Patient-reported outcome measures have been shown to have important prognostic value after various cardiac interventions. We assessed the association between the change in Kansas City Cardiomyopathy Questionnaire-12 (KCCQ-12) score after TAVR and mortality.

Methods

We included patients who underwent TAVR at Mayo Clinic from February 2012 to June 2022 and who completed the KCCQ-12 before and 30-45 days after the procedure. Patients were categorized into 3 groups: those who experienced significant (≥ 19 points, group-1), modest (1-19 points, group-2), and no (≤ 0 points, group-3) improvement.

Results

A total of 1,124 patients were included: 60.8% male, 97.6% white. Mean age was 79.4±8.3 years, KCCQ-12 score was 53.9±24.5, and median STS score was 4.9%(IQR: 3.1%-8.0%). At 45 days, the mean change in KCCQ-12 score was 19±24 points: 46.3%(n= 520) of patients had …
