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. Objectives We aim to describe the outcomes of patients with CHD who had surgical placement of right ventricle to pulmonary artery conduits with a focus on the risk factors for redo-surgery. Methods We performed a retrospective single-center clinical data review of patients who had RVOT surgery using RV-to-PA conduits Results Thirty-three patients (54.5% males) were included. The mean age at first conduit placement was 3.57 ± 3.18 years, mean conduit size conduit was 14.45 ± 3.85 mm. 51.5% of patients received Contegra tubes. On a mean follow-up of 2.07 ± 2.36 years, 45.5% of patients underwent RV-to-PA conduits redo replacement after 5.67 ± 3.25 years from the first surgery, 2 patients underwent re-intervention for the second time, 7 patients had transcatheter interventions on RVOT or branch PAs. The main mode of conduit failure was stenosis. The median survival without the need for surgical reintervention was 2.5 years for the non-contegra subgroup versus 3 years for the contegra subgroup (P = 0.59). we predicted that 100% of the study group would require redo surgery for conduit replacement within the first 11 years post-initial surgery. For every year of age increase at follow-up, the hazard ratio for redo surgery increases by a factor of 1.47. For every year of age increase at the time of first operation, the hazard ratio for redo surgery decreases by a factor of 0.7. Conclusions The use of conduits to treat the RV to PA discontinuity is a cornerstone in treating congenital heart diseases. Nevertheless, conduit failure and replacement are inevitable. In our experience the higher the age at the first conduit, the longer the re-intervention-free survival period. |
