Tetralogy of Fallot.

This paper reviews the available literature on normal fetal and transitional circulation and its importance in understanding the abnormal circulation related to tetralogy of Fallot (TOF). The anatomical defects of TOF are described along with the clinical manifestations related to each defect. Surgical management and risk factors, which play a major role in the anesthetic management of these patients, and the surgical corrections and associated risk factors are related to anesthetic management currently in use. Anesthetic techniques of choice, emphasizing the impact of drug interactions and complications, are reviewed. Current postoperative results are presented with long-term survival rates.
