Successful Surgical Repair of a Window Ductus and Ventricular Septal Defect in a Neonate Utilizing Preoperative Three-Dimensional Modeling.

Window ductus (WD) is a very rare and anatomically distinct variant of patent ductus arteriosus, also known as a type B patent ductus arteriosus. We report the case of a neonate who was born with a rare triad of congenital heart defects including a large WD, multiple ventricular septal defects (VSD), and an atrial septal defect (ASD). The child had significant left-to-right shunting and pulmonary hypertension, and successfully underwent complete surgical repair. At 11 years of follow-up, the patient is doing well with good flow in both the aortic arch and the pulmonary arteries. To the best of our knowledge, this is the first case of WD diagnosis associated with multiple VSDs and an ASD that has been described in the literature.
