Outcomes after inhospital, subacute, and elective TAVI in COMPARE-TAVI 1

We aimed to compare procedural, echocardiographic, and clinical outcomes within the first year after transcatheter aortic valve implantation (TAVI) among inhospital and subacute patients to elective patients in the COMPARE-TAVI 1 cohort.

Among 1030 patients treated with TAVI, 927 (90%) had an elective procedure, 63 (6.1%) had a subacute procedure, and 40 (3.9%) had an inhospital procedure. Procedural characteristics and outcomes were comparable. Among elective, subacute, and inhospital patients, mortality at 30 days was 15 (1.6%), 0 (0%), and 0 (0%) and at 1 year 54 (5.8%), 4 (6.3%), and 2 (5.0%). Stroke at 30 days was 28 (3.0%), 0 (0%), and 3 (7.5%) and at 1 year 42 (4.5%), 5 (7.9%), and 3 (7.5%). New pacemaker at 30 days was 119 (14%), 12 (21%), and 6 (17%) and at 1 year 130 (16%), 14 (25%), and 7 (19%). Elective, subacute, and inhospital patients with LVEF ≤40%, improved their LVEF from 33% (28–37), 33% (27–37), and 28% (22–33) before TAVI to 46% (35–60), 43% (33–52), and 42% (33–55) at 30-days, and 54% (45–62), 53% (43–61), and 49% (39–63) at 1-year. Differences between the groups were not statistically significant.

After transfemoral TAVI with balloon-expandable valves in COMPARE-TAVI 1, procedural, echocardiographic, and clinical outcomes were comparable among elective, subacute, and inhospital patients within the first year.
