Key result
ToF repair shows prolonged hemodynamic times and increased right heart-pulmonary blood volume vs septal repair.
Why the study?
Does the biatrial dye-dilution method reveal differences in postoperative hemodynamics between patients undergoing complete correction of Tetralogy of Fallot and those with septal defects?

Does the biatrial dye-dilution method reveal differences in postoperative hemodynamics between patients undergoing complete correction of Tetralogy of Fallot and those with septal defects?
The biatrial dye-dilution method demonstrates that patients undergoing complete correction of Tetralogy of Fallot experience significant but transient right heart and pulmonary circulatory disturbances in the immediate postoperative period compared to those with simple septal defects.
Horiuchi et al. (1969) conducted an observational in Tetralogy of Fallot and Septal Defects (n=16). Complete correction of Tetralogy of Fallot vs. Septal defect repair was evaluated on Hemodynamic time factors and right heart-pulmonary blood volume. Following complete correction of tetralogy of Fallot, right atrial dye-dilution curves showed marked prolongation of time factors and increased right heart-pulmonary blood volume in the early postoperative period compared to septal defect repairs.
