Three-Dimensional Rotational Angiography as Guidance for Percutaneous Patent Ductus Arteriosus (PDA) Device Closure: A Case Report

Abstract

Background: Patent Ductus Arteriosus (PDA) is a prevalent congenital heart defect characterized by the persistence of an open arterial connection between the aorta and the pulmonary. Percutaneous PDA closure involves deploying occlusion devices through catheter- based procedures. Case Presentation: We report a 1-year and 6-month-old girl diagnosed with Patent Ductus Arteriosus, presented with persistent complaints of failed to thrive , shortness of breath and recurrent cough. Physical examination revealed a continuous murmur at the upper left sternal border, and the Echocardiography examination confirmed a PDA with size of 4-7 mm, with diastolic shortening and dilatation of the Main Pulmonary Artery (MPA). The successful percutaneous PDA device closure procedure was performed using Three-Dimensional Rotational Angiography (3DRA), following an attempt with Two-Dimensional Angiography, which failed to determine the actual defect size in the patient. Conclusions: Confirming the morphology and size of a PDA can be difficult due to its location between the aorta and pulmonary blood vessels, making it a challenging congenital anomaly to assess accurately. 3DRA precisely delineates the PDA structure located between the aortic and pulmonary blood vessels and acts as a guidance tool for percutaneous PDA device closure.
