A reduced LAFI is associated with adverse outcome and an independent predictor of mortality in TAVR patients. TAVR improves LAFI within 12 months after the procedure. Left Atrial Function Index (LAFI) in Patients undergoing Transcatheter Aortic Valve Implantation. A Kaplan-Meier survival analysis of 1-year all-cause mortality in patients with LAFI ≤ 13.5 compared with patients with LAFI > 13.5. Comparing rates of 1-year all-cause mortality between the different LAFI groups, we found a significant association between left atrial function and mortality. LAFI Left atrial function index. B Comparison of the mean LAFI before and after TAVR. After long-term follow-up the LAFI improved significantly. LAFI Left atrial function index; FU follow-up. C Assessment of the left atrial function index using the pre-procedural transthoracic echocardiography. A Measurement of the minimal left atrial volume (LAEDV). B Assessment of the maximal left atrial volume (LAESV).
