Large aneurysms and pseudoaneurysms of surgically reconstructed right ventricular outflow tracts

Aneurysm and pseudoaneurysm development is a known, albeit uncommon, complication after right ventricular outflow tract surgical reconstruction. Large right ventricular outflow tract aneurysms and pseudoaneurysms have not been extensively described in recent literature and we report our experience with this unusual complication in five patients at our institution over the last 8 years. Although uncommon, this complication has potentially important clinical implications. Thus, clinicians should be aware of its potential, particularly in certain anatomic conditions.
