Post Transcatheter Aortic Valve Replacement outcomes among patients with Cardiac Amyloidosis and Aortic Stenosis.
Abstract Body (Do not enter title and authors here): Background Aortic stenosis (AS) and cardiac amyloidosis (CA) frequently coexist. There is a paucity of data on whether the presence of CA impacts post-procedural and clinical outcomes after transcatheter aortic valve replacement (TAVR) among AS patients. Objective In this analysis, we sought to leverage data from the TriNeTX Global Collaborative Network to determine the impact of CA on mortality and cardiovascular/ischemic outcomes at 1-month and 1-year post-TAVR. Methods The TriNeTX Global Collaborative Network research database was used to identify patients aged ≥18 years from January 2012 to April 2023. Patients with AS were categorized into two groups: one with CA and having TAVR, and a control group with non CA group having TAVR. Patients were followed for 1 month and 1 year respectively. Propensity score-matched analysis (PSM) (1:1) was performed on age, gender, race, hypertension, diabetes mellitus, and chronic kidney disease. Primary outcome was all-cause mortality (ACM), while secondary outcomes were acute myocardial infarction (AMI), ischemic stroke, ventricular arrhythmias, and major adverse cardiovascular event (composite of ACM, ischemic stroke and AMI).
Results After 1:1 PSM, the study cohort comprised of 351 patients in the CA group and 351 patients in the non-CA group. The mean age of patients in CA and non-CA groups was 79.6 and 79.5 years. PSM analysis showed that ACM was comparable between CA and non-CA group after 1-month (RR, 1.00 (95%CI: 0.42-2.39), P=0.98), and after 1-year follow up (RR, 0.92 (95%CI: 0.59-1.44), P=0.736). AMI was also found comparable between the two cohorts, both after 1-month (RR, 1.189 (95%CI: 0.503-2.811), P=0.693), and after 1-year (RR, 1.288 (95%CI: 0.598-2.773), P=0.516). Similar trends were found for ischemic stroke, ventricular arrhythmias and MACE both after 1-month and 1-year follow up.
Conclusion This study shows that TAVR can be safe to be considered among cardiac amyloidosis patients with aortic stenosis
