Video 20.20 Sano conduit is seen entering the branch pulmonary arteries
In this view the Sano conduit is seen entering the branch pulmonary arteries. Note that the pulmonary arteries appear “tented” by the conduit. Branch pulmonary artery stenosis is a concern following stage 1 with Sano modification, and extensive branch pulmonary arterioplasty is common at the time of stage 2.
