Transcatheter closure with a "single lobe" Amplatzer Vascular Plug of a tubular patent ductus arteriosus in a neonate with transposition of the great arteries and heart failure

Abstract

A patent ductus arteriosus in patients with transposition of the great arteries is usually beneficial to allow shunting between pulmonary and systemic circulations. However, if the duct is too large, it can cause haemodynamic instability, pulmonary oedema and compromised organ perfusion. We present a neonate in whom a 5 mm short and tubular ductus arteriosus was causing significant cardiac failure with necrotising enterocolitis and liver impairment, leaving him too unstable for the arterial switch operation. At day 14 of life (3.1 kg), the baby underwent successful transcatheter closure using an Amplatzer vascular plug (Abbott, Chicago, Il, USA) delivered through a 5Fr catheter from the aortic side. The procedure was uncomplicated and successful as the neonate was extubated 2 days later. He subsequently underwent successful arterial switch surgery.
