What CXR findings are expected after truncus repair?

Post-operative CXR shows median sternotomy wires, RV-PA conduit (extracardiac), improved pulmonary vascular markings (compared to pre-op plethora), and residual cardiomegaly that should resolve over weeks.

What conduit is used for truncus repair?

Rastelli repair uses a valved RV-to-PA conduit (cryopreserved homograft or bovine jugular vein conduit). Conduit position is typically anterior and to the right of midline on CXR.

When does the conduit need replacement?

RV-PA conduits typically require replacement every 5-10 years due to somatic growth in children and progressive conduit stenosis or regurgitation. Conduit dysfunction appears as right heart enlargement on echo/CXR.
