Introduction
Immune-mediated inflammatory disease (IMID) is a subset of autoimmune diseases including systemic lupus erythematosus, rheumatoid arthritis, and psoriasis that is emerging as a risk factor for many cardiovascular diseases including valvular disease.
Objectives
To determine whether IMID is associated with frequent and early development of bioprosthetic valve failure (BVF) after surgical aortic valve replacement (SAVR) and transcatheter valve replacement (TAVR).
Methods
Serial echocardiograms for patients who underwent SAVR and TAVR at Cleveland Clinic between 2000 and 2022 were assessed for time to development of BVF after procedure. ICD10 codes were used to stratify to those with and without IMID. Kaplan-Meier curve and cox proportional hazard regression analysis were used to assess for differences in development of BVF after TAVR and SAVR.
Results
351 TAVR patients (52 IMID and 299 controls) and 1961 SAVR patients (300 IMID and 1661 controls) were included. BVF after TAVR occurred in 12 (23.1%) IMID and 21 (7.0%) control patients, respectively, yielding an adjusted hazard ratio of 4.02 (1.81 - 8.92). Time to 50% of patients developing BVF was earlier among IMID, occurring at 6.6 years IMID and not reached in controls (p < 0.001). There were no significant differences in prevalence and time to development of BVF in IMID vs controls after SAVR.
Conclusion
After TAVR, BVF occurred earlier and more frequently in patients with IMID than controls. This risk should be included during shared decision making among IMID patients considered for TAVR, and may warrant more frequent monitoring post procedure. These differences in BVF were not seen after SAVR.
