Abstract

Objective: To investigate the significance of great artery ratio, for decision for right ventricular outflow tract management in patients with Tetralogy of Fallot (TOF).

 

Methods: A retrospective review of surgical record of patients operated for total correction of Tetralogy of Fallot from January 2015 to December 2015 in department of pediatric cardiac surgery NICVD was done. Patients whose aortic annual was documented in record were included in study. A relation of great artery ratio with cut off value of 0.55 with transannular patch enlargement repair and patient outcome was evaluated. Data was analysis on SPSS 21 and presented using frequency/percentage and analysis was done for any association with outcome.

 

Results: Of total 66 patients male were 44 (66.7%) and female were 22 (33.3%). Great artery ratio of 0.55 or less was calculated in 26 (39.4%) patients. While transannular patch enlargement repair of Tetralogy of Fallot was observed in 10 (15%) patients with 6 patients in GA Ratio 0.55 or less required trans annular patch enlargement compare to 4 patients in GA Ratio of >0.55 ( p=0.14 ). However a significant association of mortality was observed with, 4 (15.4%) patients expired in group with low GA Ratio compare to no mortalities in patients with GA ratio of >0.55 (p=<0.05).

 

Conclusion: In our patient population only 10 (15%) patients required transannular patch enlargement with insignificant association with low GA Ratio. However a significant association of decrease survival was observed in low ratio group.
