Thirteen patients with clinical suspicion of patent ductus arteriosus were evaluated by transthoracic and transesophageal echocardiographic studies. Findings were corroborated during corrective surgery in 8 patients and by cardiac catheterization in 5. Transthoracic echocardiography confirmed the diagnosis in 7 patients; in 2 of the patients endarteritis of the pulmonary artery was demonstrated, and in one infective vegetations in aortic and mitral valves. With transesophageal echocardiography, patent ductus arteriosus was established in all 8 patients and endarteritis of the pulmonary artery was shown in 3, including 1 not discovered by transthoracic technique. In 1 of these patients, vegetations were also found on the pulmonic valve. Both techniques demonstrated significant pulmonary hypertension in 5 cases; contrast studies showed the venoarterial shunt between the pulmonary artery and the aorta with particular clarity in transesophageal images. On the basis of these findings it may be concluded that transesophageal echocardiography complements the information provided by transthoracic recordings in adult patients with patent ductus arteriosus, especially when it is associated with pulmonary hypertension or pulmonary endarteritis.
