2. Fig 1
Kaplan-Meier estimated freedom from reoperation (FFR). The open markers indicate FFR for patients with tetralogy of Fallot with subarterial ventricular septal defect. The solid markers indicate patients with infracristal ventricular septal defect. Vertical bars indicate the lower 95% confidence intervals. The number of patients at risk are shown in parentheses (infracristal ventricular septal defect, upper row; subarterial ventricular septal defect, lower row). The FFR curves are significantly different (p = 0.01; log-rank test).

3. Fig 2
Kaplan-Meier estimated actuarial incidence of aortic valve regurgitation (AIAR) of more than mild degree. The open markers indicate AIAR for patients with tetralogy of Fallot with subarterial ventricular septal defect. The solid markers indicate patients with infracristal ventricular septal defect. Vertical bars indicate the upper 95% confidence intervals. The number of patients at risk are shown in parentheses (subarterial ventricular septal defect, upper row; infracristal ventricular septal defect, lower row). The AIAR curves are significantly different (p = ; log-rank test).

4. Fig 3
An estimated mechanism of late aortic regurgitation. Deep stitches on the distal ventricular septal patch (arrow) can fix or plicate the aortic valve annulus adjacent to the right coronary cusp (A). This can interfere with growth of this leaflet (arrows) and may cause prolapse and regurgitation in the long-term (B).

5. Fig 4
An adequate sized ventricular septal patch leaves the right ventricular outflow tract patent (A). In contrast an oversized patch with redundancy left at the distal end can obstruct the outflow tract (B).
