Abstract
Background: Surgery for congenital heart disease has progressed by leaps and bounds in the last few decades, but the right ventricular outflow tract continues to pose a challenge to the congenital heart surgeon.
Objective: To describe short and intermediate term outcome in congenital heart disease patients undergoing surgical repair using right ventricle to pulmonary artery conduits.
Patients and Methods: Our study included 33 patients that were operated upon by putting a conduit between the RV and the pulmonary artery in a single center (Al Agouza police hospital) between 2015 and 2019.
Results: This study was done in order to follow up patients who underwent surgery for conduit placement between the RV and PA, to observe the re-intervention rates and to determine the most important determinants of re-operation. 33 patients were included in this study, with age range 1.5-17 years and mean age of 8.29 +/- 4.7 years. The mean age at placement of the first conduit was 3.57 +/- 3.18 years. The youngest patient at time of conduit placement for the first time was 0.2 years old and the oldest had 12.5 years.
Conclusion: The use of conduits to treat the RV to PA discontinuity is a cornerstone in the treatment of some congenital heart diseases requiring construction of the RVOT. Nevertheless, conduit failure and replacement is inevitable, and depends on many factors: as age at first operation, type of conduit, mean and peak pressure gradient across the conduit. The higher the age at first conduit, the bigger the event / re-intervention free survival period
