A Case of Patent Ductus Arteriosus with Eisenmenger Syndrome Treated by Ligation of PDA

ABSTRACT

We experienced a case of eisenmenger syndrome treated by simple surgical intervention. Eisenmenger syndrome refers to patients with congenital heart defects who have a systemic level of pulmonary arterial pressure and high pulmonary vascular resistance, with right-to-left or bidirectional shunting. Because a progressive rise in pulmonary vascular resistance may be better tolerated with an intracardiac communication, surgical repair in such patients may shorthen their life. But, urgent surgical intervention should be undertaken to reverse process if the pulmonary vascular disease is of recent origin. Patients who respond to vasoilator therapy, such as oxygen, are subjected to surgery. We reported a case of PDA with eisenmenger syndrome whose pulmonary vascular resistance fall following vasodilator, 100% oxygen, and closure of defect during cardiac catheterization, preoperatively, and who may faborable after simple surgical repair.
