Closure of patent Potts shunt with aortic endoluminal stent graft

Pulmonary hypertension secondary to residual Potts shunt is not an uncommon phenomenon. A 59-year-old male with a history of tetralogy of Fallot was noted, on a full heart study, to have persistent pulmonary hypertension, normal left ventricular function, severe aortic regurgitation, and a residual Potts shunt. A previous surgical attempt at closure of the shunt during definitive repair was unsuccessful. An aortic endoluminal stent graft was deployed to definitively close the shunt. There was a subsequent normalization of pulmonary pressures following Potts shunt closure. The patient will now proceed with surgical aortic root repair and aortic valve replacement.
