Which option is historically used to palliate Tetralogy of Fallot?

Tetralogy of Fallot palliation historically centers on increasing blood flow to the lungs to lessen cyanosis while awaiting definitive repair. The classic approach is a shunt that connects a systemic artery to the pulmonary artery, most commonly a subclavian-to-pulmonary artery connection. This Blalock shunt temporarily boosts pulmonary perfusion and oxygenation, buying time for the baby to grow or stabilize before complete repair can be done. Other options fit different contexts: methods like.fontan or Norwood are staged strategies for other congenital heart conditions, and Rastelli is a repair technique used in TOF with specific anatomy rather than a palliative measure.
