2. Fig 1
Pulmonary valve replacement (PVR) types at each institution per 5-year interval. The number of pulmonary valve implants each year stratified by group at both institutions: St. Louis University (SLU) porcine (black bar), SLU pericardial (diagonal hatched bars), and SLU homograft (checkered bars); and Indiana University (IU) porcine (horizontal hatched bars), IU pericardial (vertical striped bars), and IU homograft (plaid bars). (HO = homograft; PE = pericardial; PO = porcine.)

3. Fig 2
The change in pulmonary insufficiency (PI) before pulmonary valve replacement (solid bars) and at latest follow-up (open bars). PR grade: 1, mild; 2, moderate; 3, severe. (HO = homograft; PE = pericardial; PO = porcine.)

4. Fig 3
The change in right ventricular end-diastolic dimension (RVEDD) indexed to body surface area before pulmonary valve replacement (solid bars) and at latest follow-up (open bars). (HO = homograft; NS = not significant; PE = pericardial; PO = porcine; RVEDD = right ventricular end-diastolic dimension.)

5. Fig 4
Quantitative comparison of the peak echocardiographic gradient (mm Hg) between the right ventricle and the main pulmonary artery before prosthetic pulmonary valve replacement (solid bars) and at latest follow-up (open bars). (HO = homograft; NS = not significant; PE = pericardial; PO = porcine.)

Kaplan-Meier actuarial freedom from valve explantation in patients (Pts) who underwent initial pulmonary valve replacement for chronic pulmonary insufficiency. (HO = homograft; PE = pericardial; PO = porcine.)
