Thoracic endovascular aortic repair (TEVAR) has emerged as an alternative treatment for adult patent ductus arteriosus (PDA) in recent years.¹ We report here our preliminary experience in treating adult PDA with stent–grafts.

Clinical Summary

From September 2005 to March 2007, a total of 4 patients with a large PDA and pulmonary hypertension underwent TEVAR. All patients had exertional dyspnea. Transthoracic echocardiography, computed tomographic angiography, and right heart catheterization were conducted before the operation. All patients had severe pulmonary hypertension. Indications for stent–graft implantation were as follows: (1) adult patient with large PDA, (2) no other congenital cardiac defects, (3) no right-to-left shunt, (4) adequate landing zone (arch diameter <35 mm), and (5) adequate access route. The study was approved by the institutional review board, and informed consent was obtained. Clinical data are summarized in Table 1.
