Abstract: The aortic origin of right or left branch pulmonary artery is a rare cardiac anomaly in which the right pulmonary artery usually arises from the ascending aorta just above the aortic sinuses, whereas the main pulmonary artery and the other pulmonary branch arise in their normal position. This article reports a rare case of isolated origin of right pulmonary artery from the ascending aorta. 2010-01-01T00:00:00Z https://www.um.edu.mt/library/oar/handle/123456789/4217 Title: An unusual vascular ring : origin of a ductus arteriosus from an aberrant right subclavian artery in a neonate with tetralogy of Fallot Authors: Walsh, Rowan; Chowdhury, Devyani; Kholwadwala, Dipak Abstract: A 2.6kg male infant with a prenatal diagnosis of congenital heart disease was delivered via normal vaginal delivery to a 29-year-old mother and subsequently evaluated at our institute. The patient was found to have arterial pre- and post-ductal saturations of 80% and physical examination revealed a holosystolic murmur. The patient did not have stridor. Low ionized calcium was also noted. Echocardiography demonstrated tetralogy of Fallot with an imperforate pulmonary valve and an unusual ductal flow pattern. Prostaglandin E1 infusion was commenced. 2010-01-01T00:00:00Z
