Acute pulmonary artery dissection in an adult with chronic pulmonary hypertension secondary to congenital heart disease: a case report.

Pulmonary hypertension and previous pulmonary artery dilatation are reported as the main underlying conditions leading to PAD. No previous cases of PAD are described in patients with history of d-TGA and atrial switch procedure. Evidence regarding the best treatment of PAD is lacking, but it seems reasonable to reduce parietal stress using pulmonary vasodilators. Nevertheless, in patients with post-capillary pulmonary hypertension, pulmonary vasodilatation may cause important pulmonary congestion.
