BACKGROUND: Pulmonary stenosis with ventricular septal defect and major aortopulmonary collaterals (PS/VSD/MAPCAs) is an extremely rare form of congenital heart defect. Although it has been assumed that PS/VSD/MAPCAs would be similar to pulmonary atresia (PA) with VSD/MAPCA, there are currently no data to support this conjecture. This study reviewed our surgical experience with reconstruction of PS/VSD/MAPCA.
METHODS: This was a retrospective review of 25 patients (14 boys, 11 girls) who were born with PS/VSD/MAPCA and underwent surgical reconstruction. Preoperative pulmonary angiography was used to define the central branch pulmonary arteries and MAPCA. Patients were a median age of 4 months at the first operation.
RESULTS: There was one operative death (4%) in this cohort of 25 patients, and complete repair was achieved in the 24 survivors (96%). There were two distinct subgroups of patients: 11 demonstrated cyanosis in the neonatal timeframe and underwent an initial procedure to augment pulmonary blood flow (+PBF). The remaining 14 patients formed the second group (-PBF). The median age at the first operation was 0.8 months in the +PBF group and 5.2 months in the -PBF group (p<0.005). Complete repair was achieved in 91% of patients in the +PBF group and in 100% in the -PBF group; however, the average number of procedures to achieve complete repair was 2.8 in the +PBF group vs 1.0 in the -PBF group (p<0.005).
CONCLUSIONS: Outcomes for PS/VSD/MAPCAs as a whole were excellent, with a low surgical mortality and high rate of complete repair. There were two identifiable subgroups with distinctive differences required in their surgical management. These results provide a prognostic outlook for patients with PS/VSD/MAPCAs that can be compared and contrasted with PA/VSD/MAPCAs.
