Fig 1 Photo shows fetal cardiac instrumentation in the in vivo arrest model. Note the sonomicrometry crystals (purple wires) on the right ventricle and the Millar catheter entering the base of the right ventricle (white) from the left side. The yellow vessel loop encircles the pulmonary artery distal from the ductus and just proximal to the first bifurcation. In the fetus, a 14-gauge plegia cannula was used to cannulate the pulmonary artery for bypass (blue tip below yellow vessel loop) and secured with a 5-0 Prolene (Ethicon, Somerville, NJ) purse string. An 18-gauge plegia cannula was used to deliver plegia to the fetal aortic root and secured by 6-0 Prolene purse string sutures.
