Neonatal Nursing Certification Review: Section 3 Cardiac Part 6.2 – TET & Tricuspid Atresia

🚨 MASTER Hypercyanotic "Tet Spells" Emergency Protocols & Single Ventricle Fontan Staging! Recognize Life-Threatening Episodes That Require Immediate Knee-Chest Positioning

👶 Tetralogy of Fallot represents the most common overall cyanotic heart defect, while tricuspid atresia exemplifies single ventricle physiology requiring complex staged palliation. This session covers the four components of TOF, distinguishes "Pink Tet" from severe forms, provides detailed hypercyanotic spell management protocols, and explains the three-stage Fontan approach. Learn why left axis deviation is pathognomonic for tricuspid atresia and how RVOT obstruction severity determines clinical presentation from mild cyanosis to ductal-dependent circulation.
