[Incidental discovery of a patent ductus arteriosus in adults].

Abstract

The patent ductus arteriosus is a vascular structure that connects the proximal descending aorta to the main pulmonary artery near the origin of the left pulmonary artery. The persistence of ductal patency after the first weeks of life is abnormal. In adults, it is most often an isolated finding but it may be associated with other congenital anomalies. Its repercussions depend on the size of the duct, varying from the absence of signs and symptoms to Eisenmenger's syndrome. Echocardiography is the keystone of diagnosis. Multimodal imaging allows precise anatomical characterization. Treatment with percutaneous placement of a closure device is recommended based on ultrasound parameters and right heart catheterization.
