Traumatic aortopulmonary window as a complication of pulmonary artery balloon angioplasty: transcatheter occlusion with a covered stent. A case report.

We describe a case in which pulmonary artery balloon angioplasty was complicated by formation of an aortopulmonary window, a previously unreported complication associated with this technique. A novel transcatheter approach for occluding the defect, a covered stent, was utilized. Deployment of the covered stent significantly reduced the shunt, allowed for clinical stabilization, and averted the need for emergency surgical intervention.
