stages of hypoplastic left heart surgery

A

Norwood to make megatrunk with unobstructed outflow

*with Blalock-Taussig shunt (artery to artery shunt: right subclavian artery to right PA)

*or Sano (modification of Norwood) to increase shunting

Q

Norwood

A

goal: all systemic flow from RV - neoaorta constructed via side-to-side anastomosis of MPA and hypoplastic aorta - Blalock-Taussig shunt to divert some flow to lungs (systemic-pulmonary shunt)

Q

Blalock-Taussig shunt

A

done in conjunction with the Norwood

BTS is a synthetic graft from Right Subclavian Artery to Right Pulmonary Artery

also…if PDA is present that is taken down to prevent overshunting to the lungs

Q

to prevent overshunting (pulmonary edema), what step needs to be done during the Blalock Taussig shunt?

A

take down a PDA if present to prevent over shunting

Q

complications of a BT shunt

A

subclavian steal syndrome
possible over shunting and pulmonary edema (worse if you don’t take down a PDA)
