  Figure 1. Forest plots of the included studies showing the pooled estimate of the frequency of transcatheter aortic valve explantations. CI, Confidence interval; EV, number of events; TRT, number of treated.

• 

  Figure 2. Forest plots of the included studies showing the pooled estimate of the mean Society of Thoracic Surgery predicted risk of mortality (STS-PROM) score at the time of transcatheter aortic bioprosthesis implant (A) and explant (B). CI, Confidence interval.

  Figure 3. Forest plots of the included studies showing the pooled estimate of the mean time interval (days) from transcatheter aortic bioprosthesis implant to explant. CI, Confidence interval.

• 

  Figure 4. Forest plots of the included studies showing the pooled estimate of 30-day mortality after surgical transcatheter aortic bioprosthesis explantation. CI, Confidence interval; EV, number of even; TRT, number of treated.

  Figure E5. Forest plots of the included studies showing the pooled estimates of the proportion of indications for transcatheter valve explantation: endocarditis (A), structured valve degeneration (B), paravalvular leak/aortic insufficiency (C), failed implantation (D), aortic stenosis (E), and others (F). CI, Confidence interval; EV, number of events; TRT, number of treated.
