Nomogram showing the total risk score as well as the individual risk score associated with each predictor. Patients are classified into 4 risk groups according to their total risk scores: very low (0–40 points), low (40–60 points), moderate (60–80 points) and high (80–100 points). AVA, aortic valve area; AVA ratio, ratio of post-procedural aortic valve area to pre-procedural area; AVA–PNA ratio, ratio of post-procedural aortic valve area to prosthetic nominal area; PPMI, permanent pacemaker implantation; RBBB, right bundle branch block
