Key result
Dacron baffle shrinkage can cause insidious late pulmonary vein obstruction after Mustard's operation.
Why the study?
Late pulmonary vein obstruction can develop after Mustard's operation despite earlier absence of this complication, necessitating close observation.
Case Report (n=3)
Late PVO may develop insidiously after Mustard repair; this case series leaves open the value of lifelong surveillance.
Three patients developed late pulmonary vein obstruction (PVO) following Mustard's operation for transposition of the great arteries. In all three the absence of PVO had been documented by an earlier postoperative cardiac catheterization. At reoperation shrinkage and kinking of the dacron baffle was evident. After Mustard's operation, patients should be observed closely for symptoms and signs of PVO since it can occur insidiously despite previously proven absence of this complication.

Driscoll et al. (1977) conducted a case report in Transposition of the great arteries (n=3). Mustard's operation using a dacron baffle was evaluated on Late pulmonary vein obstruction (PVO). Late pulmonary vein obstruction can occur insidiously following Mustard's operation using a dacron baffle due to shrinkage and kinking of the baffle.
