6. For adults with an RV-to-PA conduit, severe stenosis and/or
severe regurgitation, and symptoms or worsening functional
capacity or a sustained arrhythmia, conduit intervention
should be performed to improve cardiovascular status.*
2a B-NR
7. For adults with an RV-to-PA conduit, moderate stenosis
and/or moderate regurgitation, and symptoms or worsening
functional capacity or a sustained arrhythmia, conduit
intervention is reasonable to improve cardiovascular status.*
2a B-NR
8. For asymptomatic adults with an RV-to-PA conduit and
severe stenosis and/or severe regurgitation, and reduced RV
ejection fraction, RV dilation, or progressive tricuspid valve
regurgitation to at least moderate, conduit intervention is
reasonable to improve cardiovascular status.*
* For criteria for interventions in patients with repaired TOF and an RV-to-PA conduit, refer to
Section 4.3.5, "TOF."
