title: Long-term survival in truncus arteriosus communis type A1 associated with Ehlers-Danlos syndrome--a case report.
abstract: Long-term survival is rare in patients with truncus arteriosus communis type A1 due to the early appearance of pulmonary artery obstructive changes. A 48-year-old woman with truncus arteriosus communis type A1 diagnosed with chest radiography, two-dimensional echocardiography, and cardiac catheterization is presented. The right ventricular pressure was 108 mm Hg, whereas the systolic pulmonary artery pressure was 98 mm Hg. A concomitant diagnosis of the Ehlers-Danlos syndrome was made with clinical findings. The association of Ehlers-Danlos syndrome, in which a collagen synthesis defect is observed in arterial vessels, might have interfered with pulmonary artery intimal proliferation, thus precluding the appearance of advanced pulmonary artery luminal obstructive changes and allowing long-term survival.
