Figure 2. Comparison of Structural Valve Deterioration (SVD) in Patients Randomized to Surgery or Transcatheter Aortic Valve Implantation (TAVI).

Small aortic annuli was defined as computer tomography perimeter-derived diameter of 23 mm or smaller and large aortic annuli as greater than 23 mm. Severe SVD cases were based on status at any follow-up echocardiography, not just at last-available echocardiography. For hazard ratios (HRs), Fine-Gray P values are reported. AR indicates aortic regurgitation; AS, aortic stenosis; RCT, randomized clinical trial.
