BACKGROUND: Data regarding change in neurocognitive function after transcatheter aortic valve replacement (TAVR) are conflicting. We sought to investigate the change in cognition up to 6 months post-TAVR in patients with mild cognitive impairment (MCI).
METHODS: This is a prospective, observational, nonrandomized, cohort study of patients with MCI who underwent TAVR between February 2022 and June 2023 in a multicenter health care system. The inclusion criteria were TAVR patients with MCI, defined as a score of ≤25/30 on the Mini Montreal Cognitive Assessment (Mini MoCA) exam. The Mini MoCA exam was evaluated pre-TAVR, 30 days post-TAVR, and 6 months post-TAVR.
RESULTS: Of 81 enrolled TAVR patients, 73 (90.1%) and 66 (81.5%) completed 30-day and 6-month post-TAVR MoCA exams, respectively. The median age was 81 (IQR: 75.0-86.0) years and 47.4% were male. At baseline, history of stroke, transient ischemic attack, and dementia were 17.3, 9.9%, and 9.9%, respectively. The Mini MoCA scores showed a small but significant increase from the preoperative assessment to the 30-day interval (21.0 [17.5-22.5] vs. 22.0 [18.5-24.5]; p < 0.001) and was improved in 64.4% of patients. At 6 months, the Mini MoCA scores were increased in 89.4% of patients and had an absolute and significant increase of 2.3 points compared to preoperative assessment (23.3 [20.5-25.0] vs. 21.0 [17.6-22.9], p < 0.001).
CONCLUSIONS: Among patients with baseline MCI undergoing TAVR, neurocognitive function as measured by the Mini MoCA exam significantly improved at 30 days and 6 months postprocedure. TAVR in the setting of MCI is a safe therapeutic option for patients with aortic valve disease.
